    keyword=TECH: Bigbite power supply communication problems

    There appears to be a control problem with the Bigbite (Bigbox) power supply. All the readbacks on the EPICS screen are zero, and the screen reports "Comm Error", "No Response", and "Magnet Mismatch". However, the gausmeter reports that the magnet is at .9325 Tesla.

    We rebooted the IOC but that did not resolve the problem.

    While Jack was in the hall, looked at the power supply. The supply was in remote mode and the serial cable was plugged in. Could not locate the IOC, so could not tell if the serial cable is plugged in on that side.

    Since we know the magnet is on, and since we do not need to actually control it (other than to keep it on), we will live with the magnet in this state.
