Multicard Triggering
You can use multiple NI 2565 switch cards—or multiple other National
Instruments switch cards such as the NI 2503—together in conjunction
with an instrument such as a DMM. In multiple switch-card systems,
be sure to identify one switch card as the master switch card.
All other switch cards for the system are identified as slave switch cards.
The master switch card can route an external trigger from the front
connector to a PXI backplane trigger. In addition, the master switch card
can route the SCANADV trigger from the PXI backplane to either the front
connector or another backplane trigger. This functionality makes it possible
to wire external triggers from/to only one switch card in the system, which
simplifies the wiring scheme.
Note
The NI 2565 does not support triggers on the front panel connector. If the
measurement instrument is external to the chassis you must use a different
National Instruments switch card, such as the NI 2503, as the master switch card.
