Response to
Query
Live Unit Faults N/A 8 bytes Query only.
Live Unit Faults are returned as a 32 bit Hexadecimal value. Bit
values are defined as follows:
80000000 = Power Supply out of range
40000000 = Reference not locked
20000000 = 250 MHz Clock not locked
10000000 = Ext Reference Activity
08000000 = CPLD #1 not loaded
04000000 = CPLD #2 not loaded
02000000 = Mod FPGA not loaded
01000000 = Demod FPGA not loaded
00800000 = Option Card FPGA not loaded
00400000 = TRANSEC card not ready
00200000 = Modem over temperature
00100000 = Cooling Fan
00080000 = NP Card Mailbox Comm Error
00040000 = TRANSEC Card Mailbox Comm Error
Example: LUF = 00000000 indicates No Unit Faults
N/A LUF?
LUF=xxxxxxxx
