These commands display the Received Signal Strength Indication in
dBm units. The output can range from –50 dBm to –120 dBm.
RSSI is a raw signal level indicator, updated in real-time in a 1-second
interval. The RSSI command causes the

RTU [ON/OFF/0-80]

This command enables or disables the radio's internal RTU simulator,
which runs with GE MDS' proprietary diagnostics software. The
internal RTU simulator is an optional feature which is not available on
all radios; use the command to see whether
OPT
(internal RTU simulator was purchased for the radio) or
able on this radio).
You can also use this command to set the RTU's address. Use the
internal RTU for testing system payload data and pseudo bit error rate
testing. It can help you isolate a problem to either the external RTU or a
transceiver board.
For more information on using the RTU simulator in a polling environ-
ment, refer to Publication 05-3467A01.

RX [xxx]

This command displays or changes the radio's receive frequency. Nor-
mally, the radio ships to the customer programmed with the cus-
tomer-specified frequency. If you did not specify the operating
frequency when the radio was ordered, the RX frequency is set to the
center of the radio's operating band (refer to
Codes, beginning on Page 6
If you change the receive frequency more than 5 MHz from the factory's
setting, the receiver's front-end helical filters must be re-tuned. If you
also change the transmitter frequency, review the duplexer guidelines in
Section 8.4, Operating Frequency Change Considerations, beginning
on Page 89 before implementing any change.
