MDM Trouble Report for 2018 Sep 07

Telescope: 2.4m
Observer(s): Lin & Rupert (University of Michigan)
Instrument: B4K

Problem(s) Encountered:
Had issues that I believe started with the temperature-
dependent focus feature. At the end of the night, Rupert 
attempted to run the focus4k Prospero routine. I disabled
the focus feature before doing so. When I called the routine,
it seemed like the focus lost itself by the net amount it had
shifted the focus as a result of temperature. I tried to start
it at 6825 but it instead went to 6675, that difference of 
~150 being the difference as a result of the net temperature 
change. This seemed to hiccup the IC. I ended up power cycling
it three times. Each time I was unable to take an image or
even run a movie. Whenever I did this, Prospero would think
for a while and eventually abort the exposure. Then it would
eventually admit in the Prospero Status window that the IC was
down. The following error message appeared on the mono IC
monitor:

ERROR: TIMEOUT on DMA Channel 6: WordCount= 288
Timeout on WaitTC6: WordCount= 288
