Transmitter Power
Output Level
PWR [20–37]
This command sets or displays the master station’s RF forward output
power setting. Entering the
PWR
command without a parameter displays
the forward output power in dBm. Entering the
PWR
command with a
parameter ranging from 20 to 37 (verify using the
OPT
command) sets
the forward output power in dBm. The default setting is 37 dBm, which
is equivalent to 5 watts.
To read the radio’s actual (measured) power output, use the
SHOW PWR
command.
NOTE:
The RF power output of MDS 4790E ETSI certified radios is
fixed at 5 watts. No adjustment is possible.
Active Radio
Selection
RADIO [AUTO/A/B]
This command sets or displays the transceiver board selection. When
you select
RADIO AUTO
, automatic switchover is enabled. If a major
alarm is detected and a redundant radio is operational, control automat-
ically switches to the alternate radio. Use the
RADIO AUTO
setting even if
there is only one transceiver board installed. This allows you to easily
upgrade the master station at a future date by simply inserting another
transceiver board.
Entering the
RADIO
command without a parameter shows the equipped
active/inactive status for both the A and B radios.
Example: >
RADIO
Radio response:
RADIO A
RADIO A IS ACTIVE
RADIO B IS INACTIVE
Entering the
RADIO
command with a parameter of
A
or
B
forces the active
transceiver board to the A or B transceiver board
and disables standby
redundancy.
RADIO A
or
RADIO B
settings should rarely be used; they are
provided mainly for diagnostic test purposes.
Repeater Mode
REPEATER [ON/OFF]
This command sets or displays whether the radio is configured as a
repeater. Entering the
REPEATER
command without a parameter displays
the current setting (
ON
= repeater;
OFF
= not a repeater). Entering the
REPEATER
command followed by
ON
enables radio operation as a
repeater;
OFF
disables operation as a repeater.
