As user novadaq, the directory
on novabeamlinedaq00 contains some useful utilities to communicate with the hardware. All CAEN provided software.
Run CAEN upgrader GUI:
Run CAEN V1742 digitizer (outside of DAQ):
Run CAEN VME module:
./CAENVMELib-2.50/sample/CAENVMEDemo V2718 <base address, in hex (beginning 0x)> <link>
With this utilities, one can set the base address (option 2), set a register (option 1) and read etc.
CAEN base addresses:
The V1742 has a register named
POST_TRIGGER. This value is a percentage of the readout that is to be after the trigger. There is an implicit latency of around 40 ns, so in reality, the Post-Trigger percentage sets the percentage of the readout that will be after 40 ns past the trigger.
For an unknown reason, only certain values of
POST_TRIGGER are accepted and must be found by trial and error.
