EIA 232/422/485 Switches
Verify the EIA 232/422/485 switches are set to your peripheral device’s
requirements. These settings are on the Digi One IA label, the Quick Start
guide for the Digi One SP, and the reference section of this guide.
However, if you are having trouble logging on to the Digi One IA device and
assigning an IP address, set the switches to EIA-232 (1-up; 2, 3, & 4 -
down). After your initial configuration, change the switches to match your
peripheral device’s requirements. Go to Chapter 8 for additional Reference
information.
IP Address
The IP address must be configured on the device server and the Subnet
Mask and Gateway must be correct before it can be accessed on the
network
Verify the Digi device server’s IP address using PING. See Chapter 2
Getting Started page 14 for instructions.
If you are unable to PING, you may have a duplicate IP address or the IP is
not configured correctly. Go back to Chapter 2 or run the wizard from the
CD to set the IP address.
If you can PING, you can now verify the connection to the serial port on the
device server. Connect the loop back plug (shipped with your device) to the
serial port on the device server. Make a connection between the serial port
of the device server and your operating system using the following Telnet
command:
telnet 191.168.2.2 2001
(use the IP address you assigned)
Type a unique word or phrase to see if it displays on the screen properly -
that is every stroke is displayed. Verify that local echo is not on by
removing the loop back and type another word or phrase. There should be
no display. If the display is correct with the loop back, you have
successfully connected to the port and your device server is configured
correctly. To disconnect, press Ctrl ] and at the Telnet prompt, type quit.
If you are unable to Telnet to the port, make sure you are running the latest
firmware release available and the port is configured to accept inbound
