Use this command to display or program the desired RF forward output
power setting of the radio. The
PWR
command parameter is specified in
dBm and can range from 20 to 37. The default setting is 37 dBm (5 W).
To read the actual (measured) power output of the radio, use the
SHOW
PWR
command. A dBm-to-watts conversion chart is provided in
Section 6.7 ( Page 43 ).
RSSI
Received Signal
Strength Indicator
This command continuously displays the radio
’
s Received Signal
Strength Indication (RSSI) in dBm units, until you press the key.
You can read incoming signal strengths from
–
50 dBm to
–
120 dBm.
NOTE:
The RSSI samples the incoming signal for 1 to 2 sec before
providing an average reading to your computer terminal or
HHT.
RTU [ON/OFF/0-80]
RTU Simulator This command enables or disables the radio
’
s internal RTU simulator,
which runs with proprie tary polling programs (poll.exe and
rsim.exe). The internal RTU simulator is available whenever diagnos-
tics is enabled in a radio. This command also sets the RTU address to
which the radio will respond.
Use the internal RTU for testing system payload data or pseudo bit error
rate testing. It can be helpful in isolating a problem to either the external
RTU or the radio.
Use the RTU simulator in a polled environment for testing purposes. See
Publication 05-3467A01
for more information.
RX [xxx.xxxx]
Receive Frequency This command selects or displays the radio
’
s receive frequency in MHz.
The frequency step size is 6.25 kHz. Some models might be set to 5 kHz
steps to match the frequencies of some band plans.
If the customer frequency is not programmed at the factory, a default
frequency is programmed in the radio near the center of the frequency
band.
NOTE:
A large change in receive frequency (more than 5 MHz)
requires adjustment of the receiver helical filters for maximum
performance and RSSI. See
Section 6.2, Helical Filter Adjust-
ment ( Page 36 ) for details.
