I'm using PCI NI-6602 cards to time several events in different machines. It's very important that the timers don't drift. For instance, if one is triggering every 1ms and the other at 1.5ms, I need to be sure that the second timer is triggering twice for every three times of the first one.
I've been searching for the answer, but all I can find is the RTSI bus for synchronizing the cards internal to a single machine. I did see one suggestion that the RTSI bus might work across machines with the same PCI bus speed. Has anyone had any experience trying something like this? Any other ideas?
Thank you,
Gary
