NOTE: The RSSI samples the incoming signal for one to two seconds
before providing an average reading to the connected PC.
RTSKEY [ON, OFF]
Used to set/display how the radio responds to RTS keying. The default
setting is
.
RTSKEY OFF
keying the transmitter. When
suppressed.
NOTE: Terminal emulators such as HyperTerminal and Procomm
typically initiate the RTS signal continuously upon the start of
a connection. When connected to the radio's
port, this typically causes the transmitter to remain constantly
keyed. In such cases,
to be connected to the radio's
special cables or a break-out box.
RTU [ON/OFF/0-80]
This command enables or disables the radio's internal RTU simulator,
which runs with proprietary polling programs such as 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.xxxx]
This command selects or shows the radio's receive frequency in MHz.
The frequency step size is 125 Hz.
If the customer frequency has not been programmed at the factory, a
default frequency will be programmed in the radio near the center of the
frequency band. For a list of frequency bands per radio model, refer to
" Technical Specifications" on Page 43.
RXATTN [ON or OFF]
Enables or disables receive attenuation. Enable receive attenuation
when a remote is in close proximity to a master (such as on a test bench).
RXLEVEL [–20 to 0]

operation beginning on Page 46.
