Description of Arguments
Command or Query.
When enabled, when a modem is power cycled, it powers up with the Tx carrier setting OFF.
0=POCO disabled (normal operation)
1=POCO enabled – Use with caution!
EXAMPLE: <0/PCO=0 (disabled – normal operation)
Command or Query.
Sets or returns CnC operation in the form x, where:
0=Off
1=On (normal)
2=APC, C-Band, Side A
3=APC, X-Band, Side A
4=APC, Ku-Band, Side A
5=APC, Ka-Band, Side A
6=APC, C-Band, Side B
7=APC, X-Band, Side B
8=APC, Ku-Band, Side B
9=APC, Ka-Band, Side B
NOTES:
1) CnC may be enabled only if:
• The optional plug-in hardware CnC card has been installed AND a CnC FAST option is unlocked.
• The range of permitted data rates is controlled by a FAST feature code. (Read EID to decode the installed
options for the modem)
2) If CnC-APC is active (APS=22), key transmission/reception (Modulation, FEC type, Code Rate, Framing, Data Rate,
Interface) cannot be modified until CnC-APC is suspended. (Use APC command to suspend or activate.)
Command or Query. (CnC parameter)
Sets or returns CnC PMSI (Pre-Mapped-Symbol Interface) mode in the form x, where:
0=Idle
1=Redundancy (1:1 or 1:N)
2=Talk
3=Listen
Command or Query. (CnC parameter)
Sets or returns the maximum value that may be entered, in the form xxx, as the CnC Sweep frequency range depends on
the Rx symbol rate as follows:
±1 to the symbol rate (ksps)/2
18ksps to 64ksps:
64ksps to 389ksps: ±1 to 32 kHz
389ksps to 2000ksps:
±1 to 10% of sym rate
>2000ksp
±1 to 200 kHz
EXAMPLE: <0/CCF=030
Command or Query. (CnC parameter)
Sets or returns CnC min/max delay value in milliseconds, in the form xxxyyy, where:
xxx=minimum delay
yyy=maximum delay
Maximum allowable value is 330ms
EXAMPLE: <0/CSD=010325
