Possible Cause and Resolution
a. The voltage is too low, or is the wrong polarity. Check for
the proper supply voltage at the power connector
(6–30 Vdc). See Figure 2-4 on Page 20
b. This is a transient condition. Cycle the power and wait
approximately 30 sec for the radio to restart. Recheck for
normal operation.
a. The Remote network address does not match the desired
AP. Verify that the system has a unique network address.
b. The Remote is not yet associated with a transceiver having
the same network address. Use the RADIO command to
check the status of the process of associating the radio
with the AP.
c. Poor antenna system. Check the antenna, feedline, and
connectors. Reflected power should be less than 10% of
the forward power reading (SWR 2:1 or lower). Also, check
for the proper heading of the directional antennas as
described in Aiming Directive Antennas for Maximum RSSI
on Page 162.
The radio is reporting an alarm condition. View the current
alarms and the Event Log. Correct the problem if possible
(see "Using Logged Operation Events" on Page
Blinking continues until the source of the alarm is corrected
(for example, a valid IP address is entered, and so on).
a. Verify that the Ethernet cable is connected at both ends.
b. Verify that the proper type of Ethernet cable
(straight-through or crossover) is used. See
the proper cable type.
Check the configuration of the COM port and the remote serial
gateway settings.
