PTT [0-255]
Push-to-Talk Delay
This command sets or displays the key-up delay in milliseconds. This
timer specifies how long to wait after the radio receives a key signal,
before actually keying the radio.
REF [xxxxx]
Reference Frequency
RSSI
Received Signal Strength Indicator
This command continuously displays the radio's Received Signal
Strength Indication (RSSI) in dBm units, until you press the Enter key.
Incoming signal strengths from -50 dBm to -120 dBm can be read.
NOTE: The RSSI samples the incoming signal for one to two seconds
before providing an average reading to the connected PC.
RTU [ON/OFF/0-80] Digital Only
RTU Emulator
This command enables or disables the radio's internal RTU simulator,
which runs with proprietary factory 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.
RXTOT [NONE, 1-255]
Loss of RX Data Alarm Time
The
RXTOT command selects or displays the receive time-out timer
value in minutes. This timer triggers an alarm (Event 12) if data is not
detected within the specified time.
Entering the
RXTOT command without a parameter displays the timer
value in minutes. Entering the
RXTOT command with a parameter
ranging from
0 to 255 resets the timer in minutes. Entering the RXTOT
command with the parameter
NONE disables the timer.
