Goals

1. test gam
2. issue motor commands

Log

1. Start Up
   1. opened hatch 
   2. ran new gam cable from telescope gam cable to control room where gam is
   3. opened dfm tcs
   4. turned on drives, mtr drive chasis, unhalted motors
   5. no joy in success issuing commands from dfm tcs
2. restart
   1. closed dfm tcs
   2. flipped switches off on mtr driver chasis
   3. turned off and then back on gam switch
   4. reopened dfm tcs
   5. flipped on switches on mtr driver chasis
   6. dfmtcs→telescope→gam→communication
   7. gam communication status: "Success" and south filter wheel updated after manually moving it from position 3 to position 4
3. Testing encoders over 37-pin cable
   1. Encoders going over 37-pin cable:
      1. South filter wheel position
         1. Manually changed south filter wheel position via wheel
         2. Sent "Update GAM Status" command via GAM panel
         3. It updated to the correct position
         4. Took a few more seconds (5s) to report "Success" in GAM Communication Window
      2. Rotating Mirror Position
         1. Rotating Mirror claims position 5
            1. DFM Manual (pg 21) says this means LOL We don't know. It only supports readouts 0-3 
         2. after rotating in several positions, still reports position 5
         3. cannot get the encoder for this to respond
      3. Translating Stage
         1. when stowed, reports 1
         2. when in center of mirror, reports 2
         3. this is CORRECT according to DFM manual

Todo

1. Need to buy AMP 14-pin connector for 2" filter wheel motor
2. Need to buy new belt for 2" filter wheel 
3. Need to buy 25 pin serial connector (DB 25S serial connector)

Note

1. Remote ability to hit reset switch would be nice -meyer
