I am using the USB-TC to send a digital output by ULx in Labview, this works fine for DIO0 and DIO2 but the other ports will not communicate. Is there some calibration or configuration which I have not done correctly?

The only configuration required is to set the direction of desired bits to output (since they default to input), but this is done for you in the ULx for LabVIEW driver. First, with LabVIEW closed all the way, use InstaCal’s digital output test to confirm that all 8 output bits function properly. Be sure to tighten down the screw terminals, since the tops of the screws do not make electrical contact with the internal circuitry until they are screwed down. Once the hardware and connections are proven OK in InstaCal, close InstaCal and open the following LabVIEW example, which should run OK without changes: ULx Write Dig Chan.vi
