Richard, Vern, Jim, Dave

We have started building the test system for the new SUS software watchdog system. We are initially testing using the ITMY/BSC8 system. Richard verified all coil drivers for BSC8 suspensions (ITMY and FMY) are disabled.

Richard cabled the DAC output from TCS to the ITMY ADC system. In addition, the following DACs were connected back to the ITMY ADC0: ITMY DAC0, BSC8-DAC0 (HEPI) and BSC-DAC1 (ISI). Please see drawing D1200460 for details:

Jim and Dave created a test model to run on h2tcsl0 to drive its DAC outputs. The model is called h2cdsswdawg and runs on an unused core on h2tcsl0 as dcu122. This model was tested to output analog voltages from h2tcsl0 DAC0 which are then digitized by h2susb478 ADC. One channels from TCS DAC0 is also fed back into a TCS ADC channel for verification, this was also tested.

We built a new model to replace h2susitmy on h2susb478. This model reads the ADC channels which are being used for the OSEM simulation in these tests, and it can be used to excite ITMY DAC0 channels. This model is called h2cdsswdb478 and has dcuid30 (replaces itmy model). We took out the h2itmyoptlev model for these tests.

All models are built using advLigoRTS/branch/branch-2.5. The DAQ was reconfigured to support these new models.

We made a first attempt at installing the software WD onto h2iopsusb478 but that is still a work in progress.
