digital output/analog input synchronization with PCI-DIO-32HS and 6110E

[pblase]

I'm testing an FPA (focal plane array sensor chip) that needs a bunch of clocks. I'll generate the clocks (which are all synchronized to the main pixel frequency) with a PCI-DIO-32HS, and digitize the input with a 6110E card, connecting the two with the RTSI cable. I'm still studying exactly how to interconnect them. Which would be better, in your opinion: to use the -32HS to drive the 6110E, or the other way around? I was thinking of using pattern mode on the -32HS and then driving the 6110E with the REQ signal, but it could just as well go the other way. The frequency would be around 56kHz.

You are correct it can go either way and I see no benefit to a particular configuration. I would however, use RTSI bus to trigger the slave card. I have had an occasion that a motor controller, VFD, problem prevented me from using the RTSI bus. Using a high speed optcoupler and a comparator on one of the 32 HS lines solved the problem of isolating the trigger line. (32HS triggered PCI7030 RTCard)

My intuition would tell me to use the 32HS to drive the 6110 as a slave, but it should work either way.

Most importantly I wanted to mention that it does not sound like you are using a Real-Time based (7030, FieldPoint, or PXI) system. You would get a much larget audience to your questions if asked in the general DAQ group.
