New TwinCAT/Beckhoff software was installed for the new intensity stabilization servo for the OPO pump and the CLF. Channels names are of the form H1:SQZ-OPO_ISS and H1:SQZ-CLF_ISS. A screen shot of a new medm is attched.
Finally, we hooked up the DB37 controls cable and used the tester to verify that the controls interface is working. All channels are ok.

The DAQ channels for the intensity stabilization servos of the OPO pump and the CLF have been added to the SQZ front-end model. A new ADC channel concentrator (variant 2) was added in ISC-C1/U40 and the DB9 cables connected. The error and control channels of both servos are combined into a single DB9 cable and were connected to the 7th port of ADC2 of the lsc front-end.
Updated drawings here: Squeezer wiring diagram (D1700384), ADC and DAC channel usage for ISC (T1100472), ISC LVEA Equipment Room Rack Layout (D1001427), SQZ R1 rack layout (D1600511), and RF signal distribution (E1100591).

The second CLF delay line phase shifter was in the wrong rack location and in the way of the new intensity servo for the CLF. Moved the chassis up to the correct location, and removed the old AM modulated AOM driver. Dressed the new controls cables and prepared power coords for the new intensity stabilization chassis.
