Communication Troubleshooting
It can be difficult to troubleshoot a new radio or modem system that does
not communicate properly due to the fact it has never been proven. As a
result, all the initial hardware and software settings are suspect. More
than one problem can be present and causes component replacement to
be an inadequate troubleshooting technique.. The following checklist can
serve as an aid:
•
Insure the base radio is working for other locations.
•
Verify that the Station ID and Device ID match WinCCU’s ID
Manager and it is the only device with that ID.
•
Verify baud rate, stop bits, security code and the listen cycle time
match in WinCCU and PCCU.
•
Verify the wiring from the NGC8206 to the Optional Equipment Unit
(OEU) terminal strip and then the terminal strip to the radio. Verify
the cable from the radio to the antenna.
•
Verify J9 and J11 switches on the NGC termination board are in the
proper position. (See the figure above and the table on previous
page).
For more information on troubleshooting, see Chapter 5-Troubleshooting
in the NGC8206 User’s Manual.
