Redundant
Mute Mode
CRM= 1 byte Command or Query.
Determines how the offline unit handles the mute state during a redundant switchover condition.
If the redundant mute mode is off, the offline unit will be muted. If the redundant mute mode is
on, the offline unit's mute state will not be changed.
0 = Off
1 = On
Default Value: 0
Example: <1/CRM=0’cr’
>0001/CRM=’cr’’lf’

Operating RF
Frequency
FRE=xxxxx.xxx 9 bytes Command or Query.
Sets, in MHz, valid Operating RF frequency.
For Ku BDC Tri-Band:
FRE values: 10950-11700 MHz a LO of 10000 MHz is activated
FRE values: 11700-12200 MHz a LO of 10750 MHz is activated
FRE values: 12250-12750 MHz a LO of 11300 MHz is activated
For Ku BDC Dual Band:
FRE values: 10950-11700 MHz a LO of 10000 MHz is activated
FRE values: 11700-12750 MHz a LO of 10750 MHz is activated
Example: FRE=11300.000‘cr’
Note: Operating Frequency cannot be changed for the offline unit when in redundancy mode.

Global
Converter
Configuration
GCC= variable length Command or Query.
Used to set up and query the global status of the BUC/BDC.
Example: GCC=aa.aa;b;ccccc.cc; ‘cr’ where:
aa.aa = attenuation in dB (ATT)
b = mute state, 0 = un-muted, 1 = muted (MUT)
ccccc.ccc = frequency in MHz (FRE, Ku BDC only, other units will display xxxxx.xxx)
Note: This command can only be queried for the offline unit when in redundancy mode.
