MDM Trouble Report for 2008 Nov 3

Telescope: 2.4m
Observer(s): Mark Reynolds (UofM)
Instrument: TIFKAM

Problem(s) Encountered:
At 0328 after taking an exposure the following error 
message was encountered.
 IC> WARNING: Unable to access head electronics. 
-SEC -HE IE=DISABLED 

After this, I was no longer able to contact the instrument 
and the CCD image on the IC monitor went blank.
I tried restarting ISIS/TCS/Caliban/Prospero which did not help.
In prospero, issuing a startup command failed due to the 
inability of the system to see the IE.

I also tried
pr> IC UARTINIT
 Error: Command returned error
ERROR: Can't Initialize UARTs. Head Electronics UARTs are disabled. 
Try SEQINIT. 
 Execution error in Prospero command.
 Command: IC UARTINIT

pr> IC SEQINIT
 Error: Command returned error
ERROR: Can't Initialize UARTs. Head Electronics UARTs are disabled. Try 
SEQINIT.
 Execution error in Prospero command.
 Command: IC SEQINIT

Maybe this is a hardware problem. I also note that inspection
of the instrument revealed the dewar vent to be obstructed with
snow/ice, likely due to the high humidity (> 70%). Perhaps this
contributed to the instrument crash.

Decided to close for the night at 0430 as there didn't appear 
to be much chance of resurrecting TIFKAM.
