RXTOT [NONE, 1-1440]

The command selects or displays the receive time-out timer value
RXTOT
in minutes. This timer triggers an alarm (event 12) if data is not detected
within the specified time.
Entering the command without a parameter displays the timer

SCD [0-255]

This command displays or changes the soft-carrier dekey delay in milli-
seconds.
This timer specifies how long to wait after the removal of the keying
signal before actually releasing the transmitter. A value of 0 ms unkeys
the transmitter immediately after the removal of the keying signal.

SER

This command displays the radio's serial number as recorded at the fac-

SHOW [DC, PORT, PWR]

The command displays different types of information based on

the command variables. The different parameters are:
• —Display DC input/output voltages
DC
• —Display the connector port (RJ-11 or DB-25) that is active

for diagnostics and control.
• —Display RF power output

SNR

This command continuously displays the signal-to-noise (SNR) ratio of
the received signal expressed in dB, until you press the
used in this guide, the SNR measurement is based upon the signal level
following equalization for received frames.
The SNR is an indication of the received signal quality. The SNR indi-
cation ranges from 10 dB to 33 dB. A value of 10 dB represents a very
poor signal. A value of 24 dB represents a very good signal.
