Digi One Family
The Digi One SP serial server provides reliable and cost-effective network connectivity for virtually any
type of serial device.
This compact serial server supports a wide range of protocols using serial tunneling, TCP/UDP
connections or Digi’s patented RealPort® COM port redirector for remote native COM port access.
RealPort enables existing applications to communicate, without modification, with serial devices over
the Ethernet as if they were communicating over a serial cable. Additionally, Digi One SP features
modem emulation, allowing equipment designed for modem access to communicate transparently
across the Ethernet.
PortServer TSFamily
PortServer TS serial servers offer RS-232 serial port expansion, making it easy to connect any serial
device to your network. Available in 1, 2, or 4-port models, these serial servers combine the inherent
benefits of data networking with proven asynchronous connectivity. They deliver powerful, yet simple
Ethernet connectivity for all your serial devices.
PortServer TS device servers are ideal for applications requiring COM ports or where TCP/UDP
Sockets or multicast functionality is required. All Digi device servers include Digi’s patented RealPort®
COM port redirector technology, which makes it possible to establish a connection between the host
and networked serial device by creating a local COM or TTY port on the host computer, allowing
existing software applications to work without modification.

Device set up process overview
The following is an overview of the process for setting up your Digi device. The rest of this guide
provides details on each step of the process.
Step 1: Deployment Considerations
Before beginning setup, consider the following:
n How to assign an IP address to the Digi device’s Ethernet interface, which can be accomplished
in a number of ways. See Configure the IPaddress.
n The various ways in which your Digi device can be configured. See Methods for configuring Digi
devices.
A key consideration is whether to use RealPort. Other considerations include the type of
peripheral that will connect to the port and the peripheral’s cabling requirements. See
Configure Industrial Automation (IA) and the online RealPort driver documentation and Cable
Guide, both of which are available on the Digi website, www.digi.com.
Step 2: Set Up Hardware
1. Mount brackets to side of device for rack mounting.
2. Adhere the rubber feet to the bottom of the device for desktop.
3. Connect the device to the network.
4. Connect peripherals to serial ports.
5. Connect the device to the network.
6. Connect the power supply to the Digi device.
Step 3: Download Digi Device Discovery Utility
The Digi Device Discovery Utility is a tool to help you discover Digi devices on your network. From this
utility’s interface, you can configure basic network settings and launch the configuration and
management web interface for your device. You can download the Digi Device Discovery Utility from
the Digi Device Discovery Utility support page.
Step 4: Configure an IP Address
There are a number of ways to configure an IP address. See Configure the IPaddress.
Step 5: Configure Ports

Methods for configuring Digi devices
Use this section to learn about the different methods for configuring Digi devices.
From an attached terminal
With this method, you cable a terminal or PC running terminal emulation software to a device server
port and then use the command line to enter commands. This method allows you to configure all
features. It requires, however, that you and the device server be in the same location. Some users find
it advantageous to configure the device server IP address this way and then use one of the other
methods for the rest of the configuration.
Note You cannot configure the Digi device from an attached terminal if you are using SP and DOIA. The
device type has changed from terminal to printer, which no longer allows access through the serial
port when SP and DOIA are set to factory defaults.
From a Telnet session
With this method, you Telnet to the device server and use the command line to complete configuration
tasks. The only disadvantage to this method is that you have to configure the device server with an IP
address before you can Telnet to it.
From the Web interface
The great advantage to this method is ease of use. This method requires that you configure the IP
address before you can access the configuration from the web interface, however, some features
cannot be configured this way.
To access the configuration from the web interface, follow these steps.
1. Make sure you have configured the Digi device with an IP address already. See Configure the
IPaddress.
2. Access the Digi device from a web browser by specifying the device server’s IP address in the
URL window. The web interface log in screen displays.
3. Log in to the web interface using the default user name and password.
n User name: root
n Default password: The unique default password is printed on the label on the device. If
the password is not on the label, the default password is dbps. If neither password
works, the password may have been changed. Contact your system administrator.

Download a configuration file
With this method, you configure a Digi device and then do the following:
1. Download an existing configuration file to a host system.
2. Edit the file with specific configuration using a text editor.
3. Upload the file to the device server.
This an excellent method for maintaining highly similar configuration files for multiple Digi devices. The
disadvantage is that the device server requires some configuration steps, such as the IP address, to
be completed before it can be used.
Quick reference for configuring features
This table is a quick reference for configuring features and performing device tasks, the Digi devices in
which the features are supported, and where to find them in the web interface.

Configure the IPaddress
The next step in configuring your Digi product is to configure an IP address and access the device for
more advanced configurations. You must set the initial IP before you can use the web interface. Once
the IP is set, the device can be accessed through the web interface and any changes made including
changing the IP address.
Before you begin
Before you configure your device server, write down the MAC Address located on the bottom of your
product. For Digi One IA and Digi One SP products, the MAC address also serves as the serial number.
Options for configuring the IPaddress and mask
The device server IP address can be configured using the following methods:
n From the command line, using the “set config” command. See Digi One and PortServer TS
Family Command Reference for more details including syntax and supported devices.
n By updating the ARP table on a server and then pinging the Digi device. This is called ARP-Ping.
See Configure the IP address using ARP-ing.
n Using a DHCP server. See Configure an IP Address using DHCP and RARP.
n Using a RARP server. See Configure an IP Address using DHCP and RARP.
n The IP address and mask can also be changed using the web interface, but not for initial IP
address configuration.
Configure the IP address using ARP-ing
An IP address can be configured by manually updating a server’s ARP table and then pinging the Digi
device.
The ARP-Ping command assigns the IP address you designate but also assigns default subnet mask
and gateway addresses. It is necessary to change the subnet mask and gateway addresses.
This procedure assumes that your Digi device is connected to the Ethernet network.
1. Record the MAC address of the Digi device. The MAC address is on the label side (bottom) of the
unit.
2. Access a server on the same subnet as the Digi device.
3. Manually update the server’s ARP table using the Digi device’s MAC address and the IP address
you want assigned to the Digi device. The following is an example of how this is done on a
Windows NT 4.0 system:
Digi One Family and PortServer TS Family
18
Configure the IPaddress Configure an IP Address using DHCP and RARP
Digi One Family and PortServer TS Family
19
arp -s 191.168.2.2 00-00-9d-22-23-60
4. Ping the Digi device using the IP address just assigned. For example:
ping 191.168.2.2
The ping will probably time out before there is a response from the Digi device.
5. Wait 30 seconds and then ping the Digi device again.
The Digi device replies to the ping, indicating that the IP address has been configured.
Configure an IP Address using DHCP and RARP
When the device server boots, it transmits a DHCP request and a RARP request. This continues until
an address is assigned.
n DHCP Option 12: If the device is configured to use DHCP, the combined host and domain will
be sent as a hint to the DHCP server when requesting an IP address. As a convention, some
DHCP servers use this hint to assign the IP address associated with the host name.
n DHCP Option 81 FQDN (Fully Qualified Domain Name): If the device is configured to use
DHCP, and the FQDN option is enabled in the advanced settings menu, the device will send the
combined host and domain name as a request to the DHCP server to assign the IP address
associated with the host name.
To use RARP or DHCP, follow these steps:
1. Set up an entry for an address on a DHCP or RARP server. If you intend to use RealPort, do the
following:
n Reserve a permanent IP address.
n Record the IP address. You will need it when you configure the RealPort driver.
2. Power on the device server. The DHCP or RARP server assigns the device server an IP address.
Access the Digi device
Once an IP address is set, you can access its configuration and management web interface from a
web browser.
1. Enter the IP address in the URL bar of your browser. A web interface login screen displays.
2. Log in to the web interface. The Home page for the Digi device appears allowing you to
configure the device for your specific needs. A tutorial is available to guide you in your
decisions. The Help button in the upper right corner is also available.
Configure the IPaddress Access the Digi device

3. Make any changes you need for your configuration.
4. Click Apply to save your changes.
5. Reboot when you are ready for the changes to take effect.
Configure network and serial ports
The next step in the device setup process is to configure the network and serial port settings, using
the web interface for your Digi product.
Assumptions
To access the web interface, an IP address must be assigned to your Digi product. See Configure the
IPaddress. This chapter assumes that you have logged into the web interface using the default user
name and password.

n In the Host Name field, enter a host name for a group of network devices.
3. Click Advanced Network Settings.
4. Enter the Base Socket. The base socket determines the network port (socket) on this Digi
terminal server that another network device (such as another Digi terminal server or a PC)
uses to communicate using the Digi device’s serial port services. These services include Telnet,
raw TCP/UDP, and SSL.
Most applications can leave this value unchanged. To calculate these settings:
n Telnet port = Base Socket + Serial Port Number
n Raw port = Base Socket + 100 + Serial Port Number
n SSL port = Base Socket + 600 + Serial Port Number
5. For example:
Service Base socket Network port
telnet 2000 2001
raw (TCP or UDP) 2000 2101
SSL 2000 2601

Advanced network settings
WARNING! The default Advanced Network Settings are appropriate for most
environments. Apart from setting the base socket, described in the previous topic, it is
recommended that you NOT alter the Advanced Network Settings. Changing these
settings could cause you to ‘lose’ your device on the Network. If you alter these network
settings, you may need to reset your device with the reset button and reconfigure your
device as if it were new. See Reset Device Configuration to Factory Defaults for
instructions.
Configure serial ports
1. Click Configuration > Serial Ports.
2. Click the port number that you want to configure.
3. Click Change Profile and select a profile based on the device you have connected to your port.
If this is the first profile assigned or the unit has been restored to factory defaults, the Select
Port Profile page is displayed. The following section shows the settings available for each
profile.

The available port profiles depend on supported by your Digi device. For example, if your Digi
product does not support Power Management feature, a port profiles for that feature is not
displayed. To verify whether your device supports a particular feature, see Quick reference for
configuring features. The More link provides additional details about each profile.
4. Click Apply to save the profile. The interface will determine any additional settings and port
options page will come up and ask for additional parameters if needed. See Port profiles or

Port profiles
Each port profile determines the settings needed. Following are overviews of the port profiles and
screen shots showing their settings. For more details about the port profile settings, click the Help
link.
RealPort port profile
The RealPort profile configures the serial port to interoperate with the RealPort Driver hosted on a
network-based PC. When RealPort is installed on a network-based PC, it emulates a serial port. That
is, the application “thinks” it is working with a real serial port, such as COM1. When the application
sends data to this serial port, RealPort encapsulates the data and ships it across the network to the
Digi device which in turn routes it to the serial device. This is also referred to as COM Port Redirection.
The network is transparent to both the application and the device.
With RealPort, SSL encryption is supported in network port 1027. Standard RealPort service is on
network port 771. Both can be configured on the Advanced Network Settings page. To use SSL
encryption, you must have a RealPort driver that supports SSL. For Unix and Linux, you can use one of
these drivers: Linux, Solaris, AIX, SCO Openserver 5.x and 6, and HP-UX. With Windows, you can use the
Win2k/Xp/2003 driver online, which supports Encrypted RealPort (OpenSSL/TLS1.0 128-bit AES).
A simple challenge/response MD5 hash authentication is also supported by the Windows driver on fs1.
Console Management port profile
Console Management involves accessing a device's console port over a network connection. Most
network devices such as routers, switches, and servers offer serial port(s) for management. Instead
of connecting a terminal to the console port, cable the console port to the serial port of your Digi
device. Then using Telnet features, network administrators can access these consoled serial ports
from the LAN by addressing the appropriate TCP port.
Configure network and serial ports Port profiles
Digi One Family and PortServer TS Family
28
Enabling port sharing
Under Console Management you can also enable port sharing. Port sharing allows multiple users to
access the port at the same time. If port sharing is disabled, then only one user may access the port
at a time. You may change the number of users at any time. If you increase the number of users from
2, the change takes effect immediately. If you decrease the number of users, the change does not
take effect until the users log off. For example, if port sharing is available for 9 with 9 users on, then
changed to 2, the change will not take effect until at least 2 users log off. If port sharing is enabled for
2 and then disabled, the change will not take effect until everyone is off. The default value when port
sharing is disabled is one.

Device and Driver Support for the Port Sharing Feature
n The port sharing feature and the set sharing command are supported in the following
products.
l All PortServer TS Family products.
l All Digi One products except Digi One IAP.
n The console menu feature and the Console Management port profile can be used to enable the
port sharing feature. The console menu feature and Console Manager port profile are available
on PortServer TS Family devices only. To configure port sharing for all other devices, use the
set sharing command.
n When used with RealPort, the port sharing feature is formally tested with the Windows
RealPort driver only, and not with Unix/Linux driver versions.
TCPSockets port profile
The Digi device supports TCP socket communication. TCP socket communication enables serial
devices to communicate with each other over an Ethernet network as though they were connected by
a serial cable.
Configuring TCP socket communications involves configuring the Digi device for the following types of
connections:
n Inbound connections, that is, connections that are initiated by the device on the other side of
the network.
n Outbound connection, that is, connections that are initiated by the device connected to the
serial port.
TCP Sockets profile is also the profile to use for Autoconnection. See Autoconnection.
Configure network and serial ports Port profiles
Digi One Family and PortServer TS Family
30
UDPSockets port profile
The Digi device is capable of UDP multicast. UDP multicast is used to send serial data over an Ethernet
cable to one or many hosts at the same time. UDP does not need a protocol because it sends data
without any form of acknowledgment of error or error correction.
Configure network and serial ports Port profiles
Digi One Family and PortServer TS Family
31
The number of devices that can receive a UDP multicast varies by product.
n PortServer TS 8/16 Family: up to 16 devices can receive a UDP multicast at one time.
n All other products, including the Digi One Family and PortServer TS 1/2/4: up to 64 devices can
receive a UDP multicast at one time.
Both the transmitting and receiving devices must be configured properly for UDP multicast to work.
Configuring UDP multicast communications involves configuring the Digi device for the following types
of connections:
n Inbound connections (UDPserver): Connections that are initiated by the device on the other
side of the network.
n Outbound connections (UDP client): Connections that are initiated by the device connected to
the serial port on the Digi device.
When you use UDPport profile, you are connecting a device with a serial port to the serial port on the
Digi device. The serial parameters for both devices must match. For example, if the serial port for the
device connected to the Digi device is set for 9600 bps, the serial port on the Digi device must also be
set for 9600 bps.

Serial Bridging port profile
The Digi device supports serial bridging (sometimes referred to as ‘tunneling’). A serial bridge is a
network connection between two serial devices, each of which uses a device server. The serial devices
“think” they are communicating with each other across a serial cable using serial communication

techniques. There is no need to reconfigure the server or the serial device. Neither is aware of the
intervening network.
This profile configures each side of the bridge separately. Repeat the configuration for the second Digi
device using the web interface. Enter the IP address in the URL bar of your browser and follow the
same procedure of the bridge specifying the IP address of the first Digi device.
Printer port profile
The Printer port profile allows you to connect a printer to a serial port. Use this profile if you intend to
print using the LPD protocol on your UNIX system.
Refer to your UNIX User Guide for tips on configuring the print spooler on your UNIX system.

Digi One Family and PortServer TS Family
34
Using the LPD Protocol
Here are some tips for configuring the print spooler on your UNIX system when you intend to print
using the LPD protocol to a printer attached to device server:
n The number of copies option with lpr is not supported.
n Banner pages are not supported.
n The device server’s DNS name or IP address is the remote system’s name.
n Queue names must conform to the following conventions:
l Begin the queue name with one of the following character strings: (a) Use ASCII if you want
device server to substitute carriage return and line feed characters for each line feed the
system sends. (b) Use raw if no substitution should be performed.
l After the queue name, insert an underscore character and the number of the device server
port to which the printer is attached.
l If you want to use either of the following options, specify an additional underscore and then
the letter that identifies the option: (a) Use f to append a form feed character to the end of
each file in a print job (b) Use d to add a Ctrl-d to the end of each file in a print job. (This is
often required by PostScript printers.)
Examples
String Result
ascii_1 Prints to port 1 and translates CR to
CR/LF.
ascii_8_f Prints to port 8, translates CR to CR/LF
and prints a form feed at the end of the
job.

Terminal port profile
This profile allows you to connect a terminal to the serial port. It also allows you to automatically
establish TCP connections, enabling the connection to a system or a device on the network when data
arrives.
Industrial Automation port profile
Note Before using use the Industrial Automation port profile, consider using the IA Wizard instead. The
IA Wizard is the recommended method for configuring your device for use with Industrial Automation

applications. It guides you through common IA scenarios and configures your Digi device. To launch the
IA Wizard from the web interface, click Applications > Industrial Automation > IA Wizard.
The Industrial Automation (IA) Profile allows you to connect IA devices and PLCs (programmable logic
controller) to the serial port in order to network-enable the devices. Use this profile if you need to
communicate over the network with an IA device or PLC that only uses serial protocols. This profile
may also be used to add routing capabilities to IA devices or PLCs that act as serial masters and send
packets to various systems or devices on the network. Industrial Automation enhances the IA device
or PLC connected to the serial port. Use the Help button for more assistance configuring this profile.

Configure Industrial Automation with Modbus
1. Click Serial Port > Change profile and select Industrial Automation.
2. Click Apply.
3. Under Profile settings, click Change protocol -(Master or Slave).
4. Select the serial protocol that your device expects to communicate on.
5. The only option is User defined. The User Defined IA serial protocol is useful for devices or PLCs
that do not use any of the predefined protocols and have a protocol that conforms to the
following criteria: All message packets are bounded by fixed header and trailer strings Every
protocol request is followed by a single response.
6. Use the Help button for additional information.
7. Click Apply.
Configure the serial port for the serial communication parameters (baud rate, data bits, parity and
stop bits) required by the connected IA device. If you configure the port for a slave, you do not have to
configure a network-based master. Communication with the master simply works. However, if the
master is connected to a serial port, it must be configured. If you configure a port for a master and the
slaves are located on the network, TCP sockets, UDP sockets, and Modbus/TCP are all supported. Use
the protocol required by the master.

Chat Mode port profile
This configuration allows multiple clients to simultaneously connect to or manage a server connected
to the same serial port, similar to a chat room. In chat mode, the serial device can be a slave or a
master. Enabling the device as a server (slave) allows you to establish the end of line detection, the
timeouts, and the disconnect conduct. Server settings establish the data echo direction. As a client
(master) device, the same settings apply but you may also direct your communication to a specific
port or other networked device.

Modem Emulation port profile
The Modem Emulation port profile allows you to configure the serial port to act as a modem. The Digi
device emulates modem responses to a serial device and seamlessly sends and receives data over an
Ethernet network instead of a PSTN (Public Switched Telephone Network). The advantage for a user
is the ability to retain legacy software applications without modification and use a less expensive
Ethernet network in place of public telephone lines.
For more details about modem emulation and descriptions of the commands that can be issued, see
Modem Emulation Commands in the Digi One and PortServer TS Family Command Reference.
Modem port profile
The Modem port profile configures the Digi device for attaching a modem to the serial port in order to
establish or receive connections from other systems and modems.
If the attached modem uses PPP connections, select Enable PPP Connections on this Modem and

Power Management port profile
The Power Management port profile allows you to connect the serial port to a power controller, such
as the Digi Remote Power Manager (Digi RPM). The Digi device will monitor the power controller to
provide the status and control of power outlets. This feature is used most commonly in a console
management application, where the console port of a server is connected to one serial port of the Digi
device for remote access, and the AC power plug of the server is connected to a power controller for
AC power control. Power controller settings can be automatically detected or configured manually.
Power controller outlets are configured on the Controller Outlets page, linked from the profile page.

Configure Industrial Automation (IA)
The Digi Industrial Automation (IA) capabilities enable Digi products to identify and intelligently
manage communications using several common Industrial Automation protocols. This chapter
discusses using Digi products with Industrial Automation (IA) applications, including configurations
that work for your for IA applications, and the configuration tasks required to use your Digi product in
an IA environment. The content in this chapter assumes you are familiar with the basics of the
industrial protocols you need to implement.
Key terms
Industrial Automation involves several key terms:
Term Description
Com Port Redirection
A method of redirecting the serial data
generated by a PC-based master to a slave
connected to a port on a network-based
device server. In this scheme, the master
“thinks” that it is communicating with a
device connected to a serial port on the PC
system when, in fact, the data is
encapsulated in network packets and
transported across the network to a device
connected to a serial port on the Digi device
server. Many applications, written to support
serial communication only, require this
service in order to communicate over the
Ethernet.
IA
Abbreviation for industrial automation.
master (or protocol master)
The host or IA device that initiates all
communication with a protocol slave.
multi-master
Any configuration in which more than one
master simultaneously communicates with a
slave.
Digi One Family and PortServer TS Family
56
Configure Industrial Automation (IA) Industrial Automation configuration wizard
Digi One Family and PortServer TS Family
57
Term Description
protocol request A message generated by the master and sent
to the slave that requests information or
issues a command.
protocol response
A message generated by the slave in
response to a protocol request from the
master.
slave (or protocol slave)
The device that responds to requests from
the master.
TCP socket (or TCP socket service)
A type of network service that uses TCP to
ensure reliability. When this manual discusses
TCP sockets, it means that IA protocol
messages are encapsulated in network
packets and transported across the network
using a standard network service. Many
applications support connections to devices
using TCP socket.
TCP tunnel
A TCP socket connection in which a master is
connected to the serial port of one device
server and a slave to the serial port of
another Digi device.
UDP sockets (or UDP socket service)
Similar to TCP socket service (discussed
above) except that the UDP protocol is used
instead of TCP, which means that the
reliability service TCP performs is not
provided. Advantages of UDP socket service
are slightly less protocol overhead and
support for multicasting. Some applications
support connections to devices using TCP
socket.
UDP tunnel
A UDP socket configuration in which a master
is connected to the serial port of one device
server and a slave to the serial port of
another Digi device.
Industrial Automation configuration wizard
To help you configure your Digi product for use in an IA application, a configuration wizard and several
configuration profiles, or scenarios, are provided.
To launch the wizard:
1. Log in to web interface.
2. Click Applications > Industrial Automation.
3. Click the link in the text: For a guided installation, launch the Industrial Automation
Wizard.

Serial Bridge profile: master and slave connected to Digi ports
Use this profile to connect a protocol master to the serial port of one device server and the protocol
slave (or slaves) to the serial port of another device server. This profile, which is often called a serial
bridge, is applicable to environments that use most IA serial port protocols and to multi-master
environments as well. The network is completely transparent to the serial devices, which means they
do not have to be reconfigured.
Configuration Options
The serial port connections must be configured to meet the requirements of the attached device,
which can be Modbus ASCII, Modbus RTU, DF1 Full-Duplex, Omron Hostlink, Omron FINS, and Omron
CompoWay/F. It can also be a serial port protocol that meets Digi’s definition of a “user defined”
protocol, that is, one that has fixed header and trailer strings that bound all message packets and
where each protocol request is followed by a single response.
For the network connection, Digi recommends TCP sockets, which works regardless of the serial port
protocol specified and provides an efficient and reliable network service. Another option is UDP
sockets, which also works with all the serial port protocols, although it lacks TCP socket reliability. For
Modbus devices, Modbus/TCP is an option, and for DF1 Full-Duplex devices, Allen Bradley Ethernet and
Ethernet/IP are options.

Configure MEIsettings
This section describes configuring MEI (Multiple Electrical Interface) settings through the web
interface for the PortServer TS 8 MEI* and PortServer TS 16 MEI*. The internal MEI settings are
switched to EIA-232 by default.
*Except for the PortServer TS 8 MEI and PortServer TS 16 MEI devices, the remaining Digi TS Family
have external DIP switches for MEI settings.
About MEIsettings
PortServer TS 8/16 MEI devices are shipped with the ports switched to EIA-232 by default. The 232
drivers will generate voltages of 6V max. This voltage is well within the tolerances of EIA 422/485. The
232 drivers are current limited so they can’t over-drive another EIA-422/485 output and damage their
devices.
The same engineering applies if a port is set at EIA-422 and a 232 device is connected to it. The
voltage generated is within the tolerance of the serial device and will not damage either device.
In either case, your serial device may or may not produce ‘data chatter’ - that is, text strings that have
no meaning. This is an indication that the MEI settings are not in agreement and should be configured.
If there is a loss of power to the unit, the device will not lose the MEI configuration. After it boots up, it
will recall and apply the last MEI settings.
Configure MEI switches
1. Log into the Digi PortServer TS.
2. Click Serial Ports > port #.
3. Select your port profile for your environment and click Apply.
4. Click MEI Serial Settings.
5. Select the Tx Control setting for your scenario.
n Select Tx Control > Always on if this device is the only one transmitting on one wire
pair, such as a single master in a master/slave configuration or if only two devices are
attached.
n Select Tx Control > Auto if multiple devices need to share the bus in a dual master
scenario or if the device is acting as slave in a multidrop environment. See Four-wire
multi-drop scenarios for more information about multi-drop scenarios.
6. Click Apply and the settings will take effect.
7. Repeat steps 2-6 for each port.
8. If you have not done so already, connect your serial device to the appropriate serial port.

Set the supported baud rate for multi-drop support
The PortServer TS 8/16 MEI requires setting a baud rate range in order to perform the automatic
transmitter control. This setting does not influence the performance in EIA-232 mode or for EIA-
422/485 configurations where the transmitter is always on.
The range supported by default is: 50 -230400 bps
To change the supported baud rate range
1. Select System > MEI.
2. From the Baud Rate drop-down box, select the appropriate baud rate.
3. Select Enable all serial ports (to enable the serial port transmitter) if appropriate.
4. Click Apply for configuration to take effect.
Four-wire multi-drop scenarios
There are two scenarios of devices on a four-wire multi-drop network: the Master and the Slave. A
Master has a dedicated pair of wires to talk to the Slaves. The Slaves share a return pair to the Master
and need to control their transmitters so that only one device at a time uses that pair. Following are
the specific procedures to set up a Master or Slave MEI setting.

Configure power over serial ports
The Serial Power feature available for the PortServer TS P MEI Series allows the Digi device to power
a serial device (power out) or use a serial device to power the Digi device (power in). The advantage of
this feature is to eliminate an external power supply.
Power out is available on all ports through Ring Indicator (RI) or Data Terminal Ready (DTR). Power in
is available only through RI and only on port one (1). The Serial Power feature is active on a specific
port when that port is configured for RS 232 operation.
n The power out budget equals one (1) watt (the total amount of power available). The available
power can be divided in any combination between the ports but the following rules must be
observed:
l RI = 5 volts @ up to 200 mA (max)
l DTR = 9 volts @ up to 100 mA (max)
l You may use DTR or RI as the source of power (power out) on any port but you may not use
both DTR and RI on the same port.
n Pinout information:
l RI is pin 1
l DTR is pin 9
n RI signaling is lost when the pin is used for power.
Configure Ring Indicator (RI) power
RIpower in
Ring Indicator (RI) power in accepts power into the Digi device only on port one. Power in is available
using the RI pin. The Digi device requires power in the range of 9-30 VDC @ 525mA (max). Ports 2, 3,
and 4 can still supply power to a serial device through the RI or DTR pins for each port. When using
power in through the RI, the external power supplies (both powered Ethernet and the barrel
connector power supply) are inoperative. Altpin will not work for RI power in.
1. Open the device case and move the black jumper to the following settings:
P-6 jumper on pins 1 and 2
Note When the jumper is placed correctly for power in, the jumper will set on the pins closest
to the edge of the board. The left arrow indicates the open pin and the right arrow is pointing
to the jumper.

2. Close the device unit enclosure.
RIpower out
RI power out is available on all ports. The total power budget for this feature is one (1) watt not to
exceed 5 volts @ up to 200mA on any single port. The following procedure assumes the unit will only
be used for RI power out.
1. Set the port DIP switches to the following places: switch 1 and 3 are up and 2 and 4 are down.
See Serial power table.
2. Enable the RI power through the web interface.
3. Connect power supply with the barrel-connector power supply provided with the device or use
powered Ethernet.
Note If the unit will be used with RI power in (port 1 only), set the jumper to the following
setting: P-6 jumper on pins 1and 2 and do not use an external power source. Port 1 cannot be
used for both power in and power out.
Configure DTRpower: power out
Data Terminal Ready (DTR) power out is the factory default on the Digi device. Total power budget for
this feature is one (1) watt not to exceed 9 volts @ up to 100mA to any single port.
1. Set the port DIP switches to EIA 232 (switch 1 is up, 2, 3, and 4 are down) to enable DTR power.
2. Open the port and set DTR high.
Note The graphic below shows the pins to verify the jumper position. The default position has the
jumper on the two pins furthest from the edge. DO NOT MOVE THE JUMPER FROM THE DEFAULT

Digi Remote Power Management
Digi Remote Power Manager (Digi RPM) is an intelligent power distribution unit for remote power
management that can be used with PortServer TS Family products. When integrated with PortServer
TS products, Digi RPM allows power management and device configuration from anywhere across the
corporate LAN/WAN. It provides an easy solution for the supervisory control and management of
attached electrical devices.
A Digi RPM integrated with your PortServer TS product can be used to:
n Remotely power on/off/reboot devices. Power control consists of three basic functions: on, off,
and reboot (power cycle).
n Measure electrical load and monitor ambient temperature.
n Configure alarms for 24/7 “real-time” monitoring and notification of out-of-spec conditions,
including load and ambient temperature. A user interface is provided for configuring these
alarms. Digi RPM also provides statistics on average/apparent power, RMS voltage/current,
circuit breaker status and maximum current.
n Integrate with select PortServer TS terminal servers and device servers for console and power
management over Ethernet.
Digi RPM is available in both eight-port 1U rack-mountable and ten-port 0U rack-mountable versions.
Configuration scenarios using Digi RPM
There are two typical scenarios when using Digi RPM and the power management feature with
PortServer TS Family products:
Digi One Family and PortServer TS Family
86
Digi Remote Power Management Configuration scenarios using Digi RPM
Digi One Family and PortServer TS Family
87
n A non-serial device connected to Digi RPM
n A serial device managed by a PortServer TS device, but powered by Digi RPM
Non-serial device connected to Digi RPM
The simplest scenario is a non-serial device connected to the Digi RPM; for example, an environmental
sensor controller or a tape backup device. The Digi RPM’s power-management settings are configured
and accessed through the web interface for the PortServer TS device to which it is connected. This
illustration shows a Digi RPM configured through a PortServer TS 16 for use in powering non-serial
devices.
Serial device managed by PortServer TS but powered by Digi RPM
The second configuration scenario involves a serial device, such as a router or server, that is managed
through a port on a Digi PortServer TS device, but has its power supply mapped through the Power
Management feature. The Digi RPM and power-management settings are configured and accessed
through the web interface for the PortServer TS device.
After configuration of the devices in this scenario is complete, you need only reference the console
management port on device server to also manage power. The Power Management feature handles
the relationship of a specific outlet to a serial device as if the power supply were also connected to the
same port as the serial device. In other words, you do not need to see the physical connection or
remember which outlet controls a specific serial device after configuration - the PortServer TS device

Digi RPM configurable from web interface or command line
Power management through the Digi RPM can be configured from either the web interface or
command-line interface for your PortServer TS device that is connected to the Digi RPM.
Web interface
From the web interface, which this guide emphasizes, power management is configured through the
serial port settings:
Configuration > Serial Ports > port > Port Profile > Power Management
Once set up, power management equipment is monitored and controlled at:
Management > Power
Command line
From the command line, the set powerunit command configures power management options, and
the power command controls and displays the status of the Digi RPM. See the Digi One and
PortServer TS Family Command Reference for these command descriptions.
Process for configuring and managing Digi RPM
From the web interface, configuring and managing the Digi RPM involves these steps:
1. Connect the Digi RPM to the PortServer TS device and power up.
2. Configure Digi RPM settings, including optional thresholds and alarms.
3. Configure outlets on the Digi RPM, including user access permissions to the outlets.
4. Manage power devices and power controllers.
n Manage power devices: view status of outlets and change status as needed (on, off,
reboot).
n Manage power controllers: manage individual outlets or all outlets, view current
settings in the Digi RPM, including current voltage and temperature status.

Connect Digi RPM to PortServer TSdevice and power up
To connect the Digi RPM to your PortServer TS device, use the PortServer TS to SunNetra (P/N
63000222-02) cable provided with the Digi RPM unit. Plug one side into the “Console” port of the Digi
RPM unit and the other into any port of the PortServer TS product.
Make sure that the DIP switches of the unit are set to “Off.” Plug the Digi RPM into an appropriate
power source and turn it on.
Configure Digi RPM settings
A Power Management port profile is available for use to configure your Digi PortServer device and its
serial ports for use with the Digi RPM. This port profile is used to control and manage the Digi RPM in
its power-control actions (on, off, reboot).
1. Log in to web interface.
2. Select Configuration > Serial ports.
3. Select the port number of the serial port you want to connect to the Digi RPM.
4. The Power Management port profile has configuration settings appropriate for a serial port
connected to a Digi RPM power controller. If the Power Management port profile has not
already been associated with the port through the Digi Device Setup Wizard, click Change
Profile. Select Power Management from the list of port profiles and click Apply.
5. In the Profile Settings part of the page, select whether the power controller settings will be
automatically detected or whether you will configure the settings yourself.
n Automatically Detect Power Controller: Configuration settings for the Digi RPM are
automatically detected after clicking Apply. Once the Digi RPM is detected, the settings
are populated on the page. The Manually Configure Power Controller option is
selected, allowing you to edit the settings as needed. You can correct the number of

ports, if necessary, or edit the port title.
n Manually Configure Power Controller: Configuration settings for the Digi RPM power
controller are manually entered. Enter the following, then click Apply:
Manufacturer: Select the manufacturer of the power controller.
Outlets: Enter the number of outlets on the Digi RPM power controller.
6. Optionally, set thresholds and alarms for the Digi RPM and click Apply.
Digi RPM can be configured to generate an audible alarm and an SNMP trap when either of the
following types of thresholds are reached on the unit:
n Current Alarms (amps): The current alarm threshold monitors the electric current on
the Digi RPM. You can set up to four thresholds, depending on the number of current
sensors on the Digi RPM. When the sensor's specified amperage level is reached, the
Digi RPM will emit an audible alarm. Current alarm thresholds are configurable in the
range of 0.1 to 99.9 Amps.
To generate current alarm threshold SNMP traps, you must also go to the System >
SNMP configuration page and select Generate Power Unit Current Threshold Traps
option, and specify a destination IP address for the SNMP trap.
n Temperature (°C): This alarm threshold monitors the temperature on the Digi RPM. You
can set up to four thresholds, depending on the number of temperature sensors on the
Digi RPM. When the sensor's specified temperature is exceeded, the Digi RPM will emit
an audible alarm.
Temperature alarm thresholds are configurable in the range of 0.1 to 99.9 °C
To generate temperature threshold traps, you must also go to the System > SNMP
configuration page, select Generate Power Unit Temperature Threshold Traps
option, and specify a destination IP address for the SNMP trap.
Configure outlets
Next, configure the PortServer TS to link serial ports to outlets on the Digi RPM. From each outlet on
the Digi RPM, you can set a name for it, tie its use to a serial port, and control user access to the
outlet for power management.
1. On the Port Profile page, click Controller Outlets. A list of other Digi RPM power controller’s
outlets is displayed, along with a summary of each outlet’s current configuration. The number
of outlets displayed is the same as the value entered for Outlets on the Controller Settings
page.

n In the Power Management Access section, configure user access permissions to the
outlet.
Users can be assigned permission to manage the outlet. A user with access permissions
to the outlet will have the option to power a connected device on or off or reboot the
device.
Individual users must already be configured before they can be assigned to manage
power outlets. To add users, go to Configuration > Users.
Users that currently have permission to control the outlet are listed in the
Username/Action table.
To allow a user access permissions to the outlet: In the bottom row, select a Username
and click Add.
To restrict a user from accessing the outlet: Click Remove.
Apply these users to all outlets with the same device name:
Apply these users to all outlets with the same serial port:
These options allow you to easily assign the same users to manage each outlet with the
same device name or serial port.
4. Click Apply and repeat steps 2-3 for each outlet you want to configure.
Manage power devices and power controllers
After power devices and controllers are configured, you can manage them. From the web interface, go
to Management > Power. From the command-line interface, issue the “power” command.
In the web interface, there are two power-management actions: Manage Power Devices and Manage
Power Controllers.

Configure SNMP
This section describes configuring Simple Network Management Protocol (SNMP), the network
management protocol that governs the exchange between nodes and stations.
About SNMP and the Digi device agent
This section introduces SNMP and network management in TCP/IP networks and it describes the
device server agent.
SNMP Version Support
Devices in the Digi One and PortServer TS Family support SNMP Version 1.
Network Management Components
The TCP/IP network management architecture contains the following components:
n Managed nodes such as host systems, routers, terminal and communications servers (such as
device server) and other network devices.
n One or more network managers (also called network management stations), which are the
points from which the network is managed
n Agents that reside on managed nodes and retrieve management information and
communicate this information to network managers.
n The network management protocol, SNMP, which governs the exchange of information
between the nodes and stations.
n Management information, which is the database of information about managed objects. This
database is called the management information base (MIB).
SNMP Management Agent
Each managed node contains at least one agent—a component that responds to requests from the
network manager—that retrieves network management information from its node and notifies the
manager when significant events occur.
SNMP Traps
An ‘eventing’ mechanism defined by SNMP is called a trap, which is a report or “alarm” from a
managed node to an SNMP manager that a significant event has occurred.
Digi One Family and PortServer TS Family
96
Configure SNMP Configure SNMP from the web interface
Digi One Family and PortServer TS Family
97
MIB Support
The SNMP management agent supports the following MIBs. Digi-specific MIBs are available for
downloading on the Digi Support site.
n Read-write for MIB II (RFC 1213), which is an Internet-standard MIB, consisting of managed
objects from the systems, interfaces, IP, ICMP, TCP, UDP, transmission, and SNMP group.
n Read-write for the character-stream devices using SMIv2 MIB (RFC 1658).
n Read-write for the RS-232-like hardware devices MIB (RFC 1659).
n Read-write for the device server IP Network Control Protocol of the Point-to-Point Protocol
MIB (RFC 1473).
Message Support
The SNMP agent supports the Set, Get, GetNext, and Trap messages as defined in RFC 1157. These
messages are used as follows:
n Set, which means set the value of a specific object from one of the supported MIBs.
n Get, which means retrieve the value of a specific object form one of the supported MIBs.
n GetNext, which means retrieve the value of the next object in the MIB.
n Trap, which means send traps to the manager when a particular type of significant event
occurs.
Supported Traps
The agent can send traps when any of the following occur:
n Cold starts (device server initializes)
n Authentication failures
n Login attempts

Latency tuning
This section discusses latency and a recommended process for defining and addressing latency issues
in your network and application.
What is latency?
Latency is the amount of time it takes a packet to travel from source to destination. Together, latency
and bandwidth define the speed and capacity of a network.
Several factors influence latency, including the traffic pattern and traffic generated by an application,
the physical wiring for the network, the use of various TCP/IP timers, and the amount of additional
traffic on the network besides that generated by the application.
Recommended process for latency tuning
Following is a process recommended to achieve deterministic Ethernet networking behavior. It uses
Digi commercial off-the-shelf (COTS) firmware and hardware, and not any specialized products
specifically designed to reduce latency. By following this process, you should be able to define and
address latency issues at multiple levels in your network and application.
In summary, the process involves five steps:
1. Determine the characteristics of your application, in terms of traffic pattern and amount of
traffic generated.
2. Determine the latency budget and the type of latency in which you are interested.
3. If applicable, depending on the results produced in steps 1 and 2, optimize the physical layer.
4. If applicable, depending on the results produced in steps 1, 2, and 3, optimize the network and
transport layer.
5. If applicable, depending on the results produced in steps 1, 2, 3, and 4, optimize the application
layer.
Best-case scenario
The best-case scenario for achieving deterministic Ethernet networking behavior with DIGI COTS
firmware and hardware is a unidirectional master-slave application running over an isolated Ethernet
network that is built around Ethernet switches instead of Ethernet hubs. In other words, the best-
case scenario is a network that eliminates unnecessary traffic and minimizes Ethernet collisions.
Digi One Family and PortServer TS Family
98
Latency tuning Step 1: Determine the characteristics of your applications
Digi One Family and PortServer TS Family
99
Step 1: Determine the characteristics of your applications
The first step in addressing latency is to consider the characteristics of your application in terms of
traffic pattern and amount of traffic generated.
n What is the main purpose of the application, and the primary activities?
n Traffic pattern: Is it peer-to-peer or master-slave application?
n Amount of traffic generated (x bytes every y minutes): How much data is being transmitted
from and received by the application, and over what amount of time? For example, 200 bytes of
data sent over 500 milliseconds.
Step 2: Determine latency budget and type of latency
Identifying the latency budget for your application involves defining what latency means for your
network and the application running on it. This latency budget influences how much optimization you
may need to perform at the physical, data link/network, and application layers.
n Define how much latency is acceptable.
n Is the latency one-way or round-trip?
Step 3: Optimize the physical layer
Depending on the results produced in steps 1 and 2, optimize the physical layer; that is, address the
physical-layer characteristics that can affect latency.
Optimizing the physical layer, may include, but is not limited to, these recommendations:
n Use Ethernet switches instead of Ethernet hubs to minimize unnecessary traffic and minimize
collisions.
n Use industrial-strength cabling and make sure the wiring is sound. Bad wiring can result in
increased collisions.
n Eliminate impedance mismatches.
n Avoid running communications cabling on the same tracks with power cabling or other cabling
exhibiting fast voltage swings
n Use a smaller less noise-induced error-prone Ethernet, or data rate. Lower Ethernet speeds
have higher voltages, at which background noise is less relevant and has less of an impact on
latency. Voltages associated with 10, 100, and 1000 mbps Ethernet speeds are:
l 10 mbps: 2.3V (CAT5)
l 100 mbps: 0.8V (CAT5)
l 1000 mbps: 0.5V (CAT5E/CAT6)
l Ground to earth all your networking equipment, including the Digi device.
l Use only networking equipment that is certified or known to operate well within the
required ranges for vibrations, shock, operating temperature, relative humidity, etc.
Step 4: Optimize the network and transport layers
Depending on the results produced in steps 1, 2, and 3, optimize the network and transport layers.
Optimizing the network and transport layers, may include, but is not limited to, these
recommendations:
Latency tuning Step 4: Optimize the network and transport layers
Digi One Family and PortServer TS Family
100
n Isolate any unnecessary TCP/IP traffic from the network.
n Choose smaller packets to reduce transit times through intermediate networking devices, as
most of these devices are store-and-forward.
n Increase the TCP/IP responsiveness to incoming/outgoing traffic by choosing appropriate
values for various TCP/IP timers, such as the retransmission timer, the gratuitous ARP timer,
and delayed acknowledgment timer.
n Avoid the use of time-consuming encryption facilities.
Command options for optimizing network and transport layers
A major contributor to latency for the network and transport layers is unnecessary retransmissions of
data. The command-line interface has several command options to help you reduce these
unnecessary retransmissions. Most of these options are available through the command-line interface
only, and not the web interface.
For complete descriptions of these commands and options, see the Digi One and PortServer TS Family
Command Reference.
There are several considerations for using these latency-related command options:
n Changing the options from their defaults may violate RFCs.
n Decrementing the values for these options increases the amount of network activity, for
example, there will be increased retransmissions.
n For a peer-to-peer application, you need to consider both sides of the connection and how
options are set. For example, if the setting for the “rto_min” option for the Digi device is set to
a value that is less than the setting for the “delayed_ack” option for the other side of the
connection, then there will be a forced retransmission of every packet of data. For a master-
slave application, this consideration does not apply.
Latency tuning Step 4: Optimize the network and transport layers
Digi One Family and PortServer TS Family
101
Command Option Description
set tcpip garp=30-3600
The frequency of Gratuitous ARP
(GARP) announcements. A
Gratuitous ARP is a broadcast
announcement to the network of
a device’s MAC address and the IP
address being used for it. This
allows the network to update its
ARP cache tables without
performing an ARP request on the
network.
Gratuitous ARP announcements
can affect latency in a limited way,
because some systems stall or
dispose of data that is
transmitted during an ARP cache
refresh. If this happens, setting
the Gratuitous ARP frequency to
be more often than the problem
system’s time-to-live variable can
cause it to refresh the cache
without needing to perform a
request.
Latency tuning Step 5: Optimize the application layer
Digi One Family and PortServer TS Family
102
Command Option Description
rto_min=30-1000
The TCP minimum retransmission
time out (RTO), in milliseconds.
TCP uses progressively larger
retransmit values, starting at a
minimum value that is calculated
from a sliding window of ACK
response round-trip times that is
bounded at the bottom by “rto_
min.” So, essentially, “rto_min” is
not necessarily the timeout that
will be used as the starting
retransmit timeout, but it is the
smallest such value that could be
used.
This affects latency, because
lowering “rto_min” ensures that
retransmits take place in less
time if they occur. By occurring
sooner, the network is able to
recover the lost data in less time
at the expense of possibly
retransmitting data that is still in-
flight or successfully received by
the other side, but
unacknowledged due to a
“delayed ACK” mechanism or
something similar.
set config
optimize={latency|throughput}
This option is also available in the
web interface at:
Configuration > System >
Optimization setting.
Configures how the Digi device
handles network latency.
If your Digi device handles delay-
sensitive data, choose
“optimize=latency.”
If overall network throughput is
more important than latency,
choose “optimize=throughput.”
For the Digi One IAP, the default is
“latency.” For all other models,
the default is “throughput.”
Step 5: Optimize the application layer
Optimizing the application layer may include, but is not limited to, these recommendations:
n Avoid having more than one application/network node generating time-sensitive traffic in the
network Have one traffic generator in a master-slave setup on the network.
Latency tuning Step 5: Optimize the application layer
Digi One Family and PortServer TS Family
103
n Avoid running other (management) applications, such as email, image or mp3 downloading,
etc., while time-sensitive traffic is running.
n Check whether the application itself has timers that cause retransmissions of data.
n Use firewalls.
