Acromag Binary I/O testing |
|
|
I looked into converting the QPD whitening switches for the X end to Acromag.
- To test this out and be able to freely toggle filters without messing anything up, I added a temporary dummy cdsFiltCtrl module (ACROMAG_BIO_TEST) to the c1scx model.
- The filters can be toggled from the automatically generated medm screen medm/c1scx/C1SCX_ACROMAG_BIO_TEST.adl
- The control output of the dummy filter bank is sent to a channel named C1:SCX-ACROMAG_SWCTRL.
- I was able to read in the appropriate bits from there and send them to the appropriate acromag channel using a calcout channel.
- I couldn't get individual bo channels to work. This Acromag module is configured to write to 4 channels at a time, so I set that up with an analog output channel. The calcout channel shifts each relevant bit from C1:SCX-ACROMAG_SWCTRL to the right place for writing to the Acromag.
- I connected the Acromag XT1111 Binary I/O unit to a temporary power supply and verified that toggling the filters on and off changed the output appropriately. This is a sinking output model so the output pin is connected to the return if the switch is on.

The plan from here:
- Determine how to configure these outputs to be compatible with the QPD whitening board.
- Modify the SUS PD whitening board to always use the analog filter and remove digital option in models.
- Test DACs
- Verify that the QPD whitening gain switches aren't doing anything
- Assemble new Acromag box for X end and connect to QPD whitening, SUS PD whitening and SOS driver boards
