*Channel 0 Demod
Backup Configuration
Bit 0 = Backup 1 assigned to this demodulator
Bit 1 = Backup 2 assigned to this demodulator
(0 = not assigned, 1 = assigned)
<1>
*Channel 0 Mod
Priority
Channel 0 Modulator backup priority (0-9)
<1>
*Channel 0 Demod
Priority
Channel 0 Demodulator backup priority (0-9)
<1>
*Channel 0 Switch
Style
0 = Switch Mod and Demod separately, 1 = Switch Mod and Demod
together
<2>
*Channel 0 Demod
Acquisition Delay
0h-BB7h in tenths of a second; decimal point implied. For example, a
value of 100 means 10.0 sec.
<1>
*Service Mode
0 = Normal, 1 = Service
These 10 bytes (13 bytes as of release 4.0) repeat for channels 1 – 9 (uses 90
additional bytes) (uses 117 additional bytes as of release 4.0).
The Backup Delays and Demod Acquisition Delay applies only to channels 1 - 9 (the
four channel 0 bytes are ignored). If channel 9 is configured as backup 2, then the four
channel 0 Backup Delay bytes and the two Demod Acquisition Delay bytes are
ignored.

Switch Major Alarm
Mask
Bit 0 = RAM/ROM fault
Bit 1 = No Backup for Faulted Prime
Bit 2 = Error During Backup
Bit 3 = Backup 1 Mod Error
Bit 4 = Backup 1 Demod Error
Bit 5 = Backup 2 Mod Error
Bit 6 = Backup 2 Demod Error
Bit 7 = Spare
(0 = mask, 1 = allow)
