Response to Query
Redundancy
State RED= 1 byte, value of
0 or 1 Command or Query.
Unit returns the redundancy state of the unit, where:
0 = Offline
1 = Online
*** This command can be used to force the unit offline, this is done by
sending RED=0. This is only valid if redundancy mode is enabled. If
redundancy is not enabled, then RED=0 will return an error. The unit
cannot be forced online.
*** If the unit is not in redundancy mode, then the unit will always be online.
Example: RED=0 (force unit offline)
RED=
RED?
RED*
RED# RED? RED=x
(see description of
arguments)
Restore Factory
Defaults RFD= 0Bytes Command Only
Restore Modem to Factory Defaylts
RFD= RFD= N/A
Rx Buffer
Frame RFM=
3 bytes Command or Query. (G.703 Parameters)
Rx Buffer Frame, where:
s=Defines which interface slot ( 1 or 2 )
x=Rx Ternary Code, where:
0=None ( Valid for E3, T3, and STS-1 )
1=G.751 (Valid for E3 )
2=G.752 (Valid for T3 )
3=G.753 (Valid for E3 )
4=STS-1 (Valid for STS-1 )
Note: Command valid only with CDI-10-1l G.703 interface.
Example: RFM=11 (selects G.751 for slot #1, channel #1)
RFM=
RFM?
RFM*
RFM# RFM?s
RFM=sx
(see description of
arguments)
Rx Frequency
Offset N/A 5 bytes Query only.
Unit returns the value of the measured frequency offset of the carrier being
demodulated. Values range from
± 0 to ± 100 kHz, 100 Hz resolution.
Returns 999999 if the demodulator is unlocked.
Example: RFO=+002.3 (which is + 2.3 kHz)
RFO?
RFO*
RFO# RFO? RFO=sxxx.x
Rx Frequency RFQ= 9 bytes Command or Query.
Rx Frequency (in MHz)
52 to 88 MHz, and 104 to 176 MHz (70/140 Modulator)
950 to 1950 MHz (L-Band Modulator)
Resolution=100Hz.
Example: RFQ=0950.0000
RFQ=
RFQ?
RFQ*
RFQ# RFQ? RFQ=xxxx.xxxx
Rx Frame Size N/A 1 byte Query Only.
Rx Frame Size Long/Short selection, where:
0=Short,
1=Long
Example: RFS =0 (which is Short Frame Size)
*NOTE: This is automatically detected on demod acquisition, but if the unit
is not locked, the query returns ‘x’.
RFS?
RFS # RFS? RFS =x
