Setup Overview
This section provides an overview of the setup process.
Step A: Plan
Before beginning setup, consider the following:
• How to assign an IP address to the Digi device’s Ethernet interface,
which can be accomplished in a number of ways. See "Configuring
the IP Address" on page 19.
• How to configure serial ports. 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 "Setting Up RealPort" on page 23 and the online RealPort
driver documentation and Cable Guide, both of which are on the
Software and Documentation CD.
• The various ways that your Digi device can be configured. See
"About Configuration Methods" on page 11 and "Configuration
Prerequisites" on page 12 for more information.
Step B: Set Up the Hardware
1. If the Digi device supports multiple serial port interfaces (EIA-232,
EIA-422/485), set the interface with the dip switches on the device.
2. Connect the device to power and to the network.
3. Connect peripherals to serial ports. See the Cable Guide on the
Software and Documentation CD.
Step C: Install and Setup Digi Port Authority-Remote
Digi Port Authority-Remote is a utility that provides one of the ways to
configure an IP address and also provides port monitoring. See the Digi
Port Authority-Remote Device Monitor Setup Guide, which is on the
Software and Documentation CD.
Step D: Configure an IP Address
There are a number of ways to configure an IP address. See "Configuring
the IP Address" on page 19 for more information.
Step E: Configure Ports
See the following for more information:
• "Setting Up RealPort" on page 23
• "Configuring the Serial Port Settings with the Web Interface" on
page 25
• "Configuring the Serial Port Settings from the Command Line" on

• PortServer TS 4 MEI Wireless
About This Guide
Purpose
This guide provides the following:
• Configuration and administration procedures
• Configuration examples
Audience
This manual is intended for the person responsible for configuring and
administering device server. It assumes that this person has experience
configuring network devices and is familiar with networking concepts.
Scope
This manual provides step-by-step instructions for configuring and
administering device server’s main features. It does not address how to
configure every option, provide complete information on commands, or
discuss hardware installation. These topics are covered in other
documents in the device server library.
Other Documents in the Library
Here is a list of the other documents in the library:
Device Server Quick Start Guide
The guide that comes in the package with the device server covering the
first steps necessary to get your device server up and running.
Chapter 3 Introduction 11
Digi One/PortServer TS Command Reference
This online manual, available on the Software and Documentation CD,
provides complete information on commands.
RealPort Setup Guides
These online manuals provide information on setting up servers for
RealPort software.
Online Help for the Web UI
This context-sensitive online help provides information on configuration
fields used with web browser configuration interface.
About Configuration Methods
Use this section to learn about configuration methods.
Configure the device server with the wizard
Simply follow the prompts and choose your configuration with the wizard.
Choose either a Microsoft Windows or Unix platform.
Configuring the device server 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.
Configuring the device server 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.
Configuring the device server 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.
Downloading 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.
12 Chapter 3 Introduction
Configuration Prerequisites
Accessing the Command Line from a Locally-Connected Terminal
Use this procedure to access the command line and the configuration from
a terminal connected to one of the device server’s serial ports.
1. Connect a terminal or PC to a serial port on the device server. For a
Windows HyperTerminal connection, use the cable that came in the
package.
2. Configure the parameters of the terminal or terminal emulation software
to work with the Digi serial port. The default port settings are:
• VT 100 emulation
• 9600 baud
• 8-bit character
• 1 stop bit
• No parity
3. Log on as the root user. The default password is dbps.
Log On as Root from the Command Line
1. At the log on prompt, enter root.
2. Enter the default password dbps.
Accessing the Command Line from a Telnet Session
Use this procedure to access the command line and the configuration from
a Telnet session. This procedure assumes that you have configure the Digi
device with an IP address already. See "Configuring the IP Address" on
page 19.
1. To Telnet to the device server, enter the following command from a
command prompt on another networked device, such as a server:
telnet ip-address
where ip-address is the device server’s IP address
Example: telnet 192.3.23.5
2. Log on as the root user. The default password is dbps.
Accessing the Configuration from the Web Interface
Use this procedure to access the configuration from the web interface. This
procedure assumes that you have configured the Digi device with an IP
address already. See "Configuring the IP Address" on page 19.
1. Access the device server from a web browser by specifying the device
server’s IP address in the URL window.
2. Log on as root. The default password is dbps.
Chapter 4 Configuring Wireless 13
Configuration Considerations
The PortServer TS 4 W works ONLY with the radio provided. You can use
the wizard to configure your wireless device available on the Software and
Documentation CD. You will need an Ethernet cable and a network PC to
configure the wireless device server. After assigning the IP address,
access the device from your browser by entering the IP address in the URL
address bar.
Install Radio
Place your country sticker on the back of the radio.
Slide radio into slot on top of Wireless device server BEFORE connecting
any cables or power supply. Only the radio shipped in the box will function
with the unit.
Note: Be sure that the grooves on the side of the radio are fit into the notched edges
of the Wireless device server. Gently push radio into slot; fit should be snug.
— WARNING - If the power is connected when you plug the radio
into the device server, you will be required to reboot. It is not
recommended that the radio be removed while the power is
connected!

18 Chapter 4 Configuring Wireless
Chapter 5 Configuring the IP Address 19
Options for Configuring the IP Address and Mask
The device server IP address can be configured using the following
methods:
• With Digi Port Authority-Remote, a Digi utility on the Software and
Documentation CD.
• By updating the ARP table on a server and then pinging the Digi
device (called ARP-Ping, see "Configuring the IP Address Using
ARP-Ping" on page 20).
• From the command line using the set config command ("Configuring
the Ethernet Interface from the Command Line" on page 21
.)
• Using a RARP server ("Configuring an IP Address using DHCP and
RARP" on page 22.)
• Using a DHCP server ("Configuring an IP Address using DHCP and
RARP" on page 22.)
The IP address and mask can also be changed using the web interface.
This method, however, does not work for the initial IP address
configuration.
Device Support: Digi Port Authority-Remote and ARP-Ping for IP Address
Configuration
Not all Digi devices can use Digi Port Authority-Remote and ARP-Ping for
IP address configuration. To determine if you can use these features, find
the hardware label on your Digi device and then use the table below to
determine whether this feature is available:
Configuring the Ethernet Interface with Digi Port Authority-Remote
Use this section to configure an initial IP address, subnet mask, and default
gateway using Digi Port Authority-Remote. This procedure cannot be used
to change the IP address, but only to assign the initial IP address. It also
cannot be used if a DHCP server is active.
Starting Point
This procedure assumes the following:
• That your Digi device supports this feature. See "Device Support:
Digi Port Authority-Remote and ARP-Ping for IP Address Configura-
tion" on page 19.
• That your Digi device is connected to the Ethernet network.
Chapter 5
Configuring the IP Address
Device Part Number Revision Required
Digi One IA RealPort 50000764-01 F or higher
Digi One RealPort 50000723-01 J or higher
PortServer TS 2 50000723-02 J or higher
PortServer TS 4 50000723-03 G or higher
20 Chapter 5 Configuring the IP Address
• That the Digi device has DHCP client turned on. This is the default
setting and it will be on unless it was turned off.
• That you do not have a DHCP server to serve IP address. If you do,
use the DHCP procedure. See "Configuring an IP Address using
DHCP and RARP" on page 22.
• That you have installed Digi Port Authority-Remote version 2.01.11
or later. For information on installing Digi Port Authority-Remote, see
the Digi Port Authority Remote Device Monitor Setup Guide, which
is on the Software and Documentation CD.
Procedure
1. Run Digi Port Authority-Remote.
2. If Digi Port Authority-Remote is not set for ADDP, choose ADDP as the
Discovery Protocol.
3. Click Discover.
A list of Digi devices appears. Systems with IP addresses of 0.0.0.0 need
IP addresses.
4. Select a device from the list and then click Configure.
5. Supply an IP address, subnet mask, and default gateway and then
choose OK.
Digi Port Authority-Remote configures the IP address, subnet mask, and
default gateway.
Configuring the IP Address Using ARP-Ping
Use this section to configure an IP address by manually updating a
server’s ARP table and then pinging the Digi device.
Note: 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.
Starting Point
This procedure assumes the following:
• That your Digi device supports this feature. See "Device Support:
Digi Port Authority-Remote and ARP-Ping for IP Address Configura-
tion" on page 19.
• That your Digi device is connected to the Ethernet network
Procedure
1. Record the MAC address of the Digi device. It’s on the back 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:
arp -s 143.191.2.1 00-00-9d-22-23-60
