Problem(s) Encountered:

I lost the filter wheel connection on the MIS control. I tried to reset the filter wheel and re-booting the MIS but all did not work. Eric and 2.4m observer Alejandro solved the problem but lost 1 hour.

Solution:

CAT-5 connection to the port server, located just above the south edge of the filter wheel was reseated, as was the line between the server and the filter wheel itself.
