                     Week Ending: August 17, 2001
                               Week: 29


Tom Folkers:
     1. Spent entire week at the 12 Meter rewiring UPS systems and 
        it's associated critical load.

Tom Sargent:
     1. Fixed a minor bug in the Linux driver for the 6 channel 12 bit 
        D/A. This is now used to connect the output of an unused 
        channel to one of the coarse encoder analog inputs. This 
        allows manually setting the coarse encoder input. Used as a 
        test feature in the lab.
     2. I altered the built-in shell program in servo so that it can 
        receive commands from the keyboard (the window from which 
        servo was spawned) or via sockets from another program. This 
        makes it possible to control servo via the 'sock' program.  In 
        the socket mode it sends all output back to the socket from 
        which the initiating command came. 
     3. Added a "reset encoder" command to servo.  It presumes that 
        there is a Service Position defined which is about 1 degree in 
        front of the fiducial position. It commands tracker to that 
        position. Then a state driven program begins supplying 
        position polynomials to make it run past the fiducial a few 
        times and record the cycle counters.  This is rather difficult 
        to test with the system in the lab, so it hasn't been tested 
        yet, but it compiles.  It does both azimuth and elevation 
        simultaneously.  It should be able to reset the encoders 
        within a few minutes.
     4. Rearranged the shell software into a more manageable form. It 
        is broken up into one function per command now, rather than 
        one command that contained all functions. The number of 
        commands has grown beyond what I originally expected.

Pete Hubbard:
     1. Modified the A/D chassis for mounting a second 12 volt power 
        supply. Wiring and testing the completed chassis.
     2. Adding the wiring in the D/IO board chassis to rear BNC 
        connectors.
     3. Testing A/D chassis with servo after changes.
     4. Starting to find where to pick off analog signals from Krupp 
        rack that are measured  by the new telescope drive system.

Dave Ashby:
     1. No Report.
