TROUBLESHOOTING
It is best to begin troubleshooting at the Access Point, because the rest
of the system depends on it for network synchronization and configu-
ration. If the Access Point has problems, the operation of the entire
network will be affected.
All radios in the network must meet these basic requirements:
• Adequate and stable primary power
• An efficient and properly aligned antenna system
• Secure connections (RF, data & power)
• Proper programming of the unit’s operating parameters, espe-
cially Device Mode selection (Access Point/Remote), Network
Name, and IP Address
• The correct interface between the radio and the connected data
equipment (proper cable wiring, data format and timing)
