Problem(s) Encountered:

Prospero complain about the disperser wheel (couldn''t find the disperser wheel).  Following the troubleshooting, we tried to reset the disperser, but the error persisted.

Solutions:

Cycled the power on the OSMOS IE box, and restarted TCS, MIS, and the data acquisition software.  Everything came back to life, but filter2 (currently empty) was not recognized (which caused some scripts to fail at first).  Filter2 issues were ultimately traced to a blown MicroLynx controller.  If after a power cycle, the problem persisted, it may have been necessary to perform a “call ossetup” in the Prospero command window.
