version 20: Trigger Nr (with max. 15 bits) is not always sent
Our setup:
- in EUDET mode
- use the 40MHz clock generated by TLU as a system clock
- provide a 1 Hz dummy photomultiplier signal from a pulse generator (width=30ns, amplitude is -100mV)
- assert BUSY to the TLU after receiving the TRG from TLU
- EUDAQ ini file tlu.ini
Observed issues:
- trigger signal and number has only 15 bits (see video)
- trigger signal is not always sent (randomly), but we have no idea why (Internally, all triggers are counted, because the next number sent is actually correct (see picture))
- in AIDA mode only a 40ns trigger is sent without the trigger nr
- we had to reverse the polarity of our busy signal in contrast to the manual and set the DUTIgnoreBusy= 0xF on for all devices, to get the EUDET mode working
We are using the AIDA2020 TLU:
