Maintenance and Troubleshooting
RE System Reset
Syntax: RE
The RE command resets the unit to a known state as defined by the stored parameters in nonvolatile memory.
This command does not reset the unit to the factory default settings.
RF Read RF Value
Syntax: RF ?
RF
The RF command queries the C- or Ku-band frequency to be received at the input of the ODU LNB. The range of
downlink frequencies received by the DBR are 3.7 to 4.2 GHz, 10.95 to 11.699 GHz, 11.7 to 12.2 GHz, and 12.25
to 12.75 GHz.
RR Receive Symbol Rate
Syntax: RR ?
RR
The RR command queries the current symbol rate of the DBR in symbols per second (sps). RR reflects the actual
channel symbol rate directly correlated to the occupied channel bandwidth.
SR Status Relay Mask
Syntax: SR nnnn
SR ?
SR
This command sets or reads the status relay mask. The value nnnn is a decimal number that represents the bit
map of the faults to be monitored by the status relay. For example, to set faults 6, 7, and 8, you would input 224
(32+64+128) as the value of
nnnn . (For a listing of fault monitors and their decimal weighting, refer to the FL
command.)
The default value is 4286578687, which enables all faults but FL 24 to activate the relay and front panel IDU Fault
indicator.
ST Status Query
Syntax: ST ?
ST
This command causes the receiver to display the current content of the status register. The FL ? command gives
the faults that have occurred since the last time the fault register was cleared. The ST ? command gives the
current condition of those fault monitors. Bits in the status register are defined exactly as the fault register. The ST
command will display a decimal or hexadecimal encoded value of the bits in the status register depending on the
HM command value.
TIME Time
Syntax: TIME hour_nn:minutes_nn:seconds_nn
TIME ?
This command allows the user to enter the current time of the real time clock. The clock uses 24-hour time format.
The valid range for
hour_nn is 1 to 23. The valid range for minutes_nn is 1 to 59. The valid range for seconds_nn
is 1 to 59.
