Chapter 4— Troubleshooting and Maintaining the Terminal
64 Trakker Antares 2475 Vehicle-Mount Terminal User’s Manual
Problems While Configuring 802.1x Security (continued)
Problem Possible Solution
The “AUTHENTICATING” message
appears on the screen, but the terminal
does not emit a low beep and a high beep
to indicate that it is authenticated.
This error code appears on the Error
Logger screen:
0x37B
The authentication process timed out. You may be out of range of the
MobileLAN access point that you are trying to communicate with. Try
moving closer to the MobileLAN access point.
Problems Communicating With RF Network Devices
If the 2475 is not communicating with other devices in the RF network,
check these possible problems.
Problems Communicating With RF Network Devices
Problem Possible Solution
The Network Connect status light remains on,
but you cannot establish a terminal emulation
session with the host computer. There may be a problem with the host computer, a problem with the
connection between the Intermec Gateway or DCS 30X and the host
computer, or a problem with the connection between the access point
and the host (TCP/IP). Check with your network administrator to
make sure the host is running and allowing users to login to the
system.
When you turn on the terminal after it was
suspended for 10-15 minutes or longer, the
terminal can no longer send or receive messages
over the network. The host may have deactivated or lost your current terminal
emulation session. In a TCP/IP direct connect network, you need to
turn off the “Keep Alive” message (if possible) from the host so that
the TCP session is maintained while a terminal is suspended.
The 2475 is connected to the host computer
and you move to a new site to collect data. The
Network Connect status light was on and now
begins to blink or turns off. You may have gone out of range of an access point. Try moving
closer to an access point or to a different location to re-establish
communications. Once you are in range again, the Connect icon will
appear and remain on. Any data you collected while you were out of
range will be transmitted over the network.
You are having problems with your 802.11b RF
network coverage. Make sure that the Medium Density Distribution (MDD) command
on your access point is not enabled. When MDD is enabled, the
access point distributes values for these RF coverage parameters to
your terminal: AP Density, Medium Reservation, and Microwave
Robustness. Changes made by your access point are not reflected in
the terminal menu system.
The Network Connect status light remains on,
but the host computer is not receiving any data
from the terminal. There may be a problem with the connection between the Intermec
Gateway or DCS 30X and the host computer. Check with your
network administrator or see the documentation that shipped with
the Intermec Gateway or the user’s manual for the DCS 30X to
troubleshoot any potential problems with the server.
In a TCP/IP network, there may be a problem with the connection
between the access point and the host computer. Check with your
network administrator or use your access point user’s manual to
troubleshoot any potential problems with the access point.
