The main motivation behind adding a DAC card in c1ioo was to setup an RTCDS model for the OMC. Attachment #1 shows the new look CDS overview screen. Here is what I did.
Mostly, I followed instructions from when I setup the model for the EX green PZTs.
Simulink model:
The model is just a toy for now (CDS parameters, ADC block and 2 CDS filter modules). I leave it to Aaron to actually populate it, check functionality etc. The path to the model is /opt/rtcds/caltech/c1/userapps/release/isc/c1/models/c1omc.mdl. I am listing the parameters set on the CDS_PARAMETERS block:
- host = c1ioo
- site = c1
- rate = 16k
- dcuid = 27 (which I chose after making sure that this dcuid was not used on this list which I also updated by adding c1omc and moving c1imc to "old")
- specific_cpu = 6 (again chosen after checking the available CPUs in the above list and confirming using the cset utility).
- adc_Slave = 1
- shmem_daq = 1
- no_rfm_dma = 1
- biquad = 1
Building and installing model:
Once the model was installed, I logged into c1ioo, and built and installed the models using the usual rtcds make and rtcds install instructions. Before starting the model, I edited /diskless/root.jessie/etc/rtsystab to allow c1omc to be run on c1ioo. Using sudo cset set, I verified that CPU #6 is no longer listed (if I understand correctly, the RTCDS system takes over the core).
MEDM:
To reflect all this on the MEDM CDS OVERVIEW screen, I just edited the screen.
- Moved the orange explanation of bits over to the c1iscey panel to make space in the c1ioo panel.
- Edited the macros to reflect the c1omc parameters.
DAQD:
Finally, I followed the instructions here to get the channels into frames and make all the indicators green. Went into fb and restarted the daqd processes. All looks good  . I'm going to leave the model running overnight to investigate stability. I forgot to svn commit the model tonight, will do it tomorrow.
The testing plan (at least initially) is to install the AA and AI boards from the OMC rack in 1X1/1X2. Then we will have short SCSI cables running from the ADC/DAC to these. The actual HV driving stages will remain in the OMC rack (NE corner of AS table).
@Steve, can we get 10 Male-Female D9 cables so that we can run them from 1X1/1X2 to the OMC rack?
Unrelated to this work: There were 2 crashes of the models on c1lsc, one ~6pm and one right now ~1030pm. The restart script brought everything back gracefully  ... |
