Troubleshooting ipimbs is described on this page:Troubleshooting for Controls IPIMB and Wave8s
The possible problems are that there is an issue with the EVR, the RCX boxes (data coming back from the camera) or the EDT card.
If no other physically triggered devices on the same EVR work either (other OPALs, Alviums, Zylas or Jungfraus), the problem is likely the EVR: as an expert, I would run evrsnoop. The second step is to power cycle the master (using serverStat or another method).
Should other triggered devices run, you can choose to look at the LEDs on the camera: if the are solid green, the boxes are not the issue. Should a camera have just run recently, it is likely NOT the RCX box.
The third suspect is the EDT card. Try to power-cycle the server: with luck, this will reset the card and make things work again.
My BLD misses a source:
You will have to fix this with the mask used in the bld-process in the cnf file.
