Greetings,
I'm building a laser scanning microscope system and would like to use NI FlexRIO FPGA (likely a 797xR) to digitally control the X/Y scanning mirrors and to acquire TTL pulses from three photon detectors. For that purpose, I'd need to have 40 digital output channels (16 data + 4 control channels for each mirror) and 3 digital input channels. I may also need a few more channels for shutter control, signal synchronization, etc. in the future. Therefore I have the following question:
1. I located NI 6581 and 6583 digital adapter modules. Which one would you recommend? Or is there a better option other than these two?
2. How can I wire the adapter to peripheral devices (mirrors, detectors, etc)? Can I just insert single conductor wires directly to the module's DDC pins? If a connector block (like SCB-68A for R series FPGA) is needed, which one should I get?
Thanks,
