Operations Manual

OPERATIONS 4-48
O&M of the MCC-545B PACKET DATA RADIO
12/2000
*FREQ{UENCIES}{,tx,r
x}
Set operating frequencies of the MCC-545B/S.
Componentry in the MCC-545B/S limits the usable
frequency range to a 2 MHz bandwidth. If frequencies
are to be changed outside this bandwidth, hardware
modifications must also be made. The Frequency
Synthesizer must be enabled via the SYNTH,ON
command for FREQ{UENCIES} to have any effect.
This command is meaningless on an MCC-545B.
tx = Tx frequency
in MHz times 100
rx = Rx frequency
in MHz times 100
4000 – 5000
4000 – 5000
*FULL DUPLEX
Set 545B in full-duplex mode.
IMPORTANT
When set to full-duplex mode, the 545B’s receiver is
disabled by the built-in Tx/Rx switch.
†GLOF{,nnnn,nnnn} Define the IDs for use as GLOF sensor Stations/display
total GLOF setup.
nnnn = Station ID
Master = 1 – 245
Remote = 256 –
4095
OFF disables
GLOF sensor
Stations
1 – 4095
†GLOF
MONITOR,t,action
Setup timeout (in seconds) and action for the GLOF
MONITOR Station
t = timeout in
seconds
action = ALERT,
FLOOD
10 – 3600
†*HALF DUPLEX{,n}
NOTE
Duplex state is kept in
EEPROM and probe
interval is kept in BBU
RAM.
Set Master Station to half-duplex mode and specify
number of milliseconds between idle probes. If no
parameter specified, last setting is used (default = 30).
n = milliseconds
between idle
probes
30 – 30,000
