to test the correct performance of a custom card i must send to it input signals (logic levels and analog input) using two parallel ports rs422 and i must read the result using a serial port rs232. i want to use a national instruments card to generate the input signals. can i generate logic levels and analog signal with a single card? is it possible to communicate with two parallel ports at the same time?
I am a little confused on your setup. It sounds like you are trying to output digital and analog signals from a DAQ board and then trying to read them on your custom card. I'm not quite sure how the parallel and serial ports fit in the setup.
However, I can tell you for sure that National Instruments offers many boards that are capable of both digital and analog outputs. I would recommend contacting a Sales Representative if you need help choosing the board that is best for you.
