M2i BaseXIO (enhanced trigger)
The BaseXIO option offers 8 asynchronous digital I/O lines on the base card. The direction can be selected by software in groups of four.
Two of these lines can also be used as additional external trigger sources. This allows the building of complex trigger conjunctions with external gated triggers as well as AND/OR conjunction of multiple external trigger sources like per example the picture and row synchronisation of video signals.
In addition one of the I/O lines can be used as reference clock for the Timestamp counter.
Together with the timestamp option there is one additional mode possible. When detecting a trigger event all 8 digital lines can be sampled and stored inside teh timestamp together with the time information. This allows to connect acquistions easily with external events.
