Note that by default mglDigIO is set up to write to port 2 and read from port 1 of your NI card (but you can configure this when you run the mglDigiO('init') command. You should reference your manual for the pinouts on the board you use. For the NI-6501 see [[http://zone.ni.com/reference/en-XX/help/370466V-01/device_pinouts/6501pinout/|here]]. We usually connect one digital input to: Pin 1 (black, digital ground) Pin 16 (red, port 2 input bit 0) and one digital output to: Pin 32 (black, digital ground) and Pin 27 (red, port 1 output bit 0). | + | -You should connect your input and output digital lines to the proper port and lines on your NI card that you want.
