RMRD
This command reads the current settings of the following remote main-
tenance settings.
• Power
• Frequency
RMST
This command stores the current settings of the following remote main-
tenance settings.
• Power
• Frequency
RSSI
This command displays the radio’s Received Signal Strength Indication
(RSSI) in dBm units. Incoming signal strengths from –50 dBm to –120
dBm can be read.
RTU [ON/OFF/0-80]
This command re-enables or disables the radio’s internal RTU simu-
lator, which runs with MDS’ proprietary polling programs (poll.exe and
rsim.exe). The internal RTU simulator is available whenever a radio has
diagnostics enabled. This command also sets the RTU address that the
radio will respond to.
The internal RTU can be used 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.
RX [xxx.xxxxx]
This command selects or displays the radio’s receive frequency in MHz.
The frequency step size is normally 6.25 kHz. However, other fre-
quency step sizes are available on request. Refer to Figure 4 on page 4
for the allowable frequency range. Note: A large change in frequency
(more than 5 MHz) requires adjustment of the receiver helical filters for
maximum RSSI. See 7.2 Helical Filter Adjustment for details.
RXLEVEL [–20...+3]
This command sets the analog output gain compatible with a received
signal with 2.5 kHz deviation. The values are in dBm. This function is
used when the radio is set in analog operating mode with the
MODEM
NONE command.
This setting is accurate to ±1 dBm.
