I have an application for a 6602 where I need to do the following: 1) Route signals as such: GPIO (PFI0) --> RTSI0 CTR1_Out --> RTSI1 CTR2_Out --> RTSI2 CTR3_Out --> RTSI3 CTR4_Out --> RTSI4 Note that I don't need to use those specific PFIs and Counters, I can use any of them. Furthermore, I also need to be able to do the following: The GPIO line is controlled independantly through SW. The Four counters are outputting synchronized square waves (CO FREQ), but at different phases (custom stepper pattern). This will be used in parallel with a SCXI system running an analog acquisition, and I need to be able to do one of the following: Pulse the counters a fixed number of pulses, then check the analog input from the SCXI Run the counters continuously, but synchronize the analog input to the rising edge of the first counter. I need to be able to, while running, to know the voltage at a specific coutner step number. My first stab was to route PFI0 to RTSI1, then the four counters as above. Apparently this was the wrong order, becasue the PFI0->RTSI0 route interferes with the RTSI4 route. Unfortunately, the hardware we designed for this requires that the GPIO be on RTSI0.I also am unsure how to get the counters synchronized; If I place them all in one task, they apparently are in sync, but I can't run a fixed number of steps (only continuously). Will this work? Set up all 4 counters in 4 different tasks, using a fifth counter as a timebase. Start them. Start the fifth counter to run the other 4. Also, to provide a sync signal for data acquisition for the M-Series card running the SCXI chassis, I would add another counter to the four that is set up exactly like CTR0, and then route that one over the RTSI5 pin to use as a scan clock for the SCXI.What do you all think? The big thing is getting that GPIO signal on RTSI0. Another option is to use a GPIO from the M-Series card on RTSI0, but can this be done if the board is running a SCXI controller?

Aha! I was wondering about that. Thank you.
