RT comm link in EX
After re cabling for the ALS WFS the link between slow and fast controls stopped working. The newly assigned DAQ ADC channel has a large -5V offset and seems broken. The offset is there even if nothing is connected to the AA chassis.

Changing the AA chassis didn't fix the problem. So, it is probably the ADC. To minimize the disruption we simple switched to a different channel for now.
