Ohishi-san et al, did the cabling of Dsub 9pin and 15pin cables for OMC, OMMT1 OSEMs and OSTM OSEMs last week.
We labeled the cables today and assigned ADC and DAC channels (see this photo).

We temporarily installed GW Instek DC power supply (from Titech) to supply +/- 18V for electronics in OMC rack, and connected AA/AI chassis and ADC/DAC cards (see this photo).
We made our first k1omc model and built it. It now runs under k1omc0 with DCUID of 85.
The main part of the aLIGO OMC model was copied to k1omc, and some filters where also copied.

Ch1-4 from DAC0 is now directly connected to Ch1-4 of ADC0 for test purpose.
However, for some reason, Ch1-4 of ADC0 do not respond to channel outputs of Ch1-4 of DAC0. Ch1-4 of ADC0 shows strange values (about -20 counts) even if we did not put any signal out from DAC0.
To be investigated tomorrow.
