Setup Overview
Chapter 1 Introduction 13
Setup 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: 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 21.
• The various ways in which your Digi device can be configured. See
"About Configuration Methods" on page 14 for more information.
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 "RealPort Decision Guide" on
page 69 and the online RealPort driver documentation and Cable
Guide, both of which are on the Software and Documentation CD.
Step 2: Set Up the 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. See the Cable Guide on the
Software and Documentation CD.
5. Connect the device to the network.
6. Connect the power supply to the Digi device.
Step 3: Configure an IP Address
There are a number of ways to configure an IP address. See "Configuring
the IP Address" on page 21 for more information.
Step 4: Configure Ports
See the following for more information:
• "Configuring Industrial Automation (IA)" on page 53
• "Network Settings" on page 25
Step 5: Configure Other Features as Required
See the following for information on setting up other features:
• "Security Configuration" on page 47
• "PPP Settings" on page 49
• "About Autoconnection" on page 52

About Configuration Methods
14 Chapter 1 Introduction
About Configuration Methods
Use this section to learn about the different configuration methods.
Configure the Digi Device 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.
Important: 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.
Configure the Digi Device 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.
Configure the Digi Device 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.

Accessing the Configuration from the Web Interface
Chapter 1 Introduction 15
Accessing the Configuration from the Web Interface
To access the configuration from the web interface, follow these steps.
This procedure assumes that you have configured the Digi device with an
IP address already. See "Configuring the IP Address" on page 21.
1. Access the Digi device 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.
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 user interface.
Some features are configurable from the command line interface only. In
those cases, the commands that configure the feature are noted. The
command descriptions are in the Digi One and PortServer TS Family
Command Reference.
