• The code indicates the fault condition. It blinks the number of times indicated with a 2- second pause
between each set.
1 blink = FPGA programming error
2 blinks = failure to decompress
3 blinks = CRC failure writing to flash
4 blinks = self-test failure
5 blinks = timing system failure
NOTE –
During the power-on, self- test, wait-for-host, and download- from-host
states, modes are directly allocated to the LEDs (sync is green, holdover is yellow,
and alarm is red). During normal operation, the user may set any LED to any of
the operational modes.
