4. Connect your computer to the transceiver LAN port.
See To Configure the Computer Ethernet 2 Interface for
Communication with the Transceiver LAN Port
. Send a command to the transceiver LAN port and then see if the
transceiver responds.
Note: To communicate with the transceiver’s LAN port, the computer’s connected Ethernet port must be
configured to do so. You must know the LAN port’s IP address. If you do not know the IP address, contact the
system administrator.
5. Replace the Ethernet cable.
6. Replace the transceiver. When replacing a transceiver, if the SD card contains a valid CIM script, remove the SD
memory card from the nonworking transceiver and insert and seat it in the replacement transceiver. The
replacement transceiver will use the CIM script on the SD memory card and its configuration will be the same as
the original transceiver.
6.8 RF LINK PROBLEMS
Base Station Transceiver
When the RF Link LED illuminates on the Base Station transceiver, it means that the Base Station transceiver is
connected to one or more Locomotive or Wayside transceivers.
When the LED on the Base Station transceiver is off, it means that the Base Station transceiver is not currently
connected to a Locomotive or Wayside transceiver.
Locomotive or Wayside Transceiver
When the RF Link LED illuminates on the Locomotive or Wayside Transceiver, it means that the Locomotive or
Wayside transceiver has selected and connected to a Base Station transceiver.
When the LED is off for the Locomotive transceiver, it probably means that the Locomotive transceiver detects one
or more Base Station transceivers but has not selected one.
When the LED is off for the Wayside transceiver, it could mean that the Base Station transceiver has not
communicated with the Wayside transceiver for a specified time.
Problem indicators:
The RF Link LED is off.
To troubleshoot RF link issues:
1. Make sure the transceiver is turned on and the green PWR LED illuminates and blinks.
2. Make sure the antenna cable connectors are securely connected to the antenna and to the transceiver.
3. Inspect the SD memory card to ensure it is not damaged and is seated properly in the CIM socket.
4. Make sure there is a valid CIM script file loaded from the SD card. At the XtermW prompt, enter
INICHECK,SCRIPT.
5. Use the BBEACON command to ensure that the base beacons are configured for the common channel.
6. Check the antenna for any defects or breaks.
