48 MDS 4790/9790 Series I/O Guide MDS 05-3438A01, Rev. E
Example: >RADIO
Radio response:RADIO A
RADIO A IS ACTIVE
RADIO B IS INACTIVE
Entering the RADIO command with a parameter of A or B forces the active
transceiver board to the A or B transceiver board, and disables standby
redundancy.
RADIO A or RADIO B settings should rarely be used; they are
provided mainly for diagnostic test purposes.
Repeater Mode REPEATER [ON/OFF]
This command sets or displays whether the radio is configured as a
repeater. Entering the
REPEATER command without a parameter displays
the current setting (
ON = repeater; OFF = not a repeater). Entering the
REPEATER command followed by ON enables radio operation as a
repeater;
OFF disables operation as a repeater.
Received Signal
Strength Indicator
RSSI, RSSI!
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, continuously updated in real-time
at about a 1-second interval. The RSSI command causes the
DIAG-
NOSTIC PORT to enter an RSSI update mode. The DIAGNOSTIC PORT
will provide an updated RSSI output line at roughly a 2-second interval
refresh rate. The
DIAGNOSTIC PORT will stay in this mode until you
press the
Enter key on the PC.
The
RSSI! command provides a one-time reading and display of RSSI at
the diagnostic port.
Remote Terminal
Unit
RTU [ON/OFF/0-80]
This command enables or disables the radio’s internal RTU simulator,
which runs with MDS’ proprietary diagnostics software. The internal
RTU simulator is an optional feature which may or may not be available
on a particular radio; use the
OPT command to see whether DIAGNOSTICS
is
ON (internal RTU simulator was purchased for the radio) or OFF (not
available on this radio).
This command can also be used to set the RTU’s address. The internal
RTU is used for testing system payload data and pseudo bit error rate
testing. It can be helpful in isolating a problem to either the external
RTU or a transceiver board.
