(where
n
represents the fan number, and then click

) to the
transceiver for each fan you turn on to turn fans off when you have finished testing them, or alternatively restart the
transceiver (using the
BOOT
command, for example) to return all fans to normal operation.

VERIFY SETTINGS THAT ALLOW THE TRANSCEIVER TO TRANSMIT
The transceiver will not transmit if calibration is not locked or if the transceiver is uncommissioned. If the transceiver
boots up normally and everything else appears normal except that the transmitter will not transmit, check these
settings to verify they have been set correctly.
5.7.1
VERIFY TRANSCEIVER CALIBRATION IS LOCKED
With the computer connected to the transceiver MAINT port, use the
CALIBRATION
or
CAL
command to determine
whether radio calibration is locked and if not to lock it.
To determine if the transceiver calibration is locked and if necessary lock the transceiver calibration:
1.
If it is not already connected, connect the computer to the transceiver
MAINT
port using a Category 5 or better
Ethernet cable.
2.
On the computer, open the
XtermW
application.
3.
Click Send, click Command, and then type:
CAL
4.
Click
OK
.
The transceiver will return a Calibration status of either “CAL Params are LOCKED” or “CAL Params are
UNLOCKED.”
If the transceiver returns a status of “CAL Params are LOCKED,” the transceiver calibration is locked and you can
continue on to the next procedure.
If the transceiver returns a status of “CAL Params are: UNLOCKED,” do the following to lock the transceiver
calibration parameters:
