Subject: etmx slow daq chassis 

This evening I transitioned the slow controls to c1auxex2.

  1. Disconnected satellite box
  2. Turned off c1auxex
  3. Disconnected DIN cables from backplace connectors
  4. Attached purple adapter boards
  5. Labeled DSub cables for use
  6. Connected DSub cables to adapter boards and chassis
  7. Initiated modbus IOC on c1auxex2

Gautam and I then proceeded to test basic functionality

  1. Pitch bias sliders move pitch, yaw moves yawyes.
  2. Coil enable and monitoring channels work yes
  3. Watchdog seems to work. yes We set the treshold for tripping low, excited the optic, watchdog didn't disappoint and triggered.
  4. All channels Initialize with "0" upon machine/server script restart. This means the watchdog happens to be OFF, which is good yes. It would be great if we could also initialize PIT and YAW to retain their value from before to avoid kicking the optic. This is not straightforward with EPICS records but there must be a way.
  5. We got the local damping going yes.
  6. There is some problem with the routing of the fast BIO channels through the new chassis - so the ANALOG de-whitening filter seems to be always engaged, despite our toggling the software BIO bits no. Something must be wrongly wired, as we confirmed by returning only the FAST BIO wiring to the pre-acromag state (but everything else is now controlled by acromag) and didn't have the problem anymore. Or some electrical connection is not made (I had to use gender changers on these connectors due to lack of proper cabling)
  7. The switches for the QPD gain stages did not work. no I suspect a wiring problem, since the switching of the coil enables did work.

Arms are locked, have been for ~1hour with no hickups. We will leave it like this overnight to observe, and debug further tomorrow.
