To change the frequency for channel 1 from 290 kHz to 325 kHz, you can type in:
$PCMNBC,SEND,MAP C1 F325000<CR><LF>
The above command will create Channel 1 if the channel is not already exists, or modify the
frequency if the channel exists. It is recommended that you always modify the existing
channel when possible instead of adding a channel. This is because the more channels you
add into the table, the longer the beacon start up time will be.
If the command is taken, you will see a response $PCMNBR,@00. If you see the return
parameter is not @00 but @01 or any other number led by @, the beacon receiver is too
busy to take the input. In such case you should send the command again. This applies all
commands you send to the beacon (Note response values without the leading @ symbol do
not follow this convention).
You
MUST
save your Channel Map by $PCMNBC,SEND,MAP SAVE<CR><LF>, otherwise
the beacon will restore the previous channel map once the G2B is powered off.
Change the Scanning mode
To enquire the current scanning mode, you can type in:
$PCMNBC,SEND,SCAN FREQ<CR><LF>
The response should be $PCMNBR,1 or $PCMNBR,2. Returning of 1 indicates that the
beacon is in the full range automatic scanning mode; returning of 2 indicates that it is in the
channel map scanning mode.
To set the scanning mode to a particular mode, add the frequency mode value to the above
command. For example, this command set the beacon to the channel map scanning mode:
$PCMNBC,SEND,SCAN FREQ 2<CR><LF>
