[Brahms-dev-l] trigger issues

As you may have seen a NIM module was switched today (3/15) Beware Ides of March . 
I have observed for some runs that the trigger 6 did not in fact trigger the LVL0
trigger logic even though the bits were enabled. I saw it earlier, and again today while looking at some data for run10881. Therefore I changed
the module (being lucky enough to find a spare). This hopefully fixes the problem. Remains is still the influence on previous runs. One way to decide is look at trigger 6 before LVL) (word 2 lower 8 bits) and see if present when trigered as it should be.
I do not knpw the extend of this  problem, but it must be investigated carefully, otherwise a wrong normalization could be taken  for triger 6
(FFS).
