Troubleshooting - GE TransNET 900 Reference Manual

Historical information on the quality of each zone can be accessed using the
command. The report shows you the number of data frames sent,
ZONE DATA
the number received, and the number received with errors. If an excessive
number of errors are seen in one or more frequency zones, it may indicate
interference, and you should consider "skipping" those zones using the
command (See "SKIP [NONE, 1...8]" on Page
Note: If a frequency zone has been skipped, all counts for that zone will be
zeros.

7.0 TROUBLESHOOTING

Successful troubleshooting of the transceiver is not difficult, but requires a
logical approach. It is best to begin troubleshooting at the Master station, as
the rest of the system depends on the Master for polling instructions and
synchronization data. If the Master station has problems, the operation of the
entire network will be affected.
When communication problems are found, it is good practice to begin by
checking the basics. All radios in the network must meet these basic require-
ments:
• Adequate and stable primary power
• An efficient and properly aligned antenna system
• Secure connections (RF, data & power)
• Proper programming of the radio's operating parameters, especially
Operating Mode (
Baud Rate (
• The correct interface between the radio and the connected data
equipment (proper cable wiring, data format and timing).
• In store-and-forward systems there are several areas that should be
checked or evaluated:
• Look for duplicate
Duplicates will cause failures unless the radios are too far apart to
hear each other.
