Should other triggered devices run, you can choose to look at the LEDs on the camera: if the they are solid green, the boxes/fibers connecting them 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. serverStat will take the DAQ alias as argument, no need to peruse the cnf-file.

My <detector> damages often (but configures):

One of the things to check here is the EVR: first, run 'evrsnoop' on the EVR host machine (typically dad-<instrument>-master).

The command is

/cds/group/pcds/dist/pds/current/build/pdsapp/bin/x86_64-rhel7-opt/evrsnoop -h

-h will list all options, you will need to specify which EVR with the '-r  a/b/c' option and which event codes you want to check with the -o <code> option. I would usually use event code 40 as that should always come and you can check if the fiducial differ by 3. The output should look something like this:

After confirming that the EVR receives the event codes, check that the cable at the back of the card is properly seated and that the correct channel is running to your detector.

Received Fiducial 010353  Event code 40  Timestamp 11828

Received Fiducial 010356  Event code 40  Timestamp 11828

Received Fiducial 010359  Event code 40  Timestamp 11828

Received Fiducial 01035c  Event code 40  Timestamp 11828

After confirming that the EVR receives the event codes, check that the cable at the back of the card is properly seated and that the correct channel is running to your detector.

My BLD misses a source:

You will have to fix this with the mask used in the bld-process in the cnf file.
