Delay Unit Control Computer: Block Failure
Sometimes ASSISTANCE complains that the delay unit block -1
has failed. This refers to the delay unit control computer (DUCC).
The problem usually responds
to stop/restart in CAOBS. However, occasionally you may
need to re-program the correlator (config). If this doesn't
work seek help from your Duty Astronomer. You may need to reset
the DUCC computer itself (which is located in the delay unit racks
in the screened room). Be sure to re-program the correlator after
restarting this machine.
