Thanks for the information. The file you sent is the same as the programming I am using in LabVIEW. At this point I have decided to move on to a National Instruments device. This device is still unstable when combined with 2 other similar (1024LS) devices running at the same time in the same program.

I have 3 USB-1024LS digital units, 2 are for output 1 for input. At start of LabVIEW the input module sends a 5 volt signal out to all pins. After I run a digital test with InstaCal it shows a failure and then turns the 5 volt signal off and is then ready for input. I test each pin with a 5 volt signal and it picks up the signal LabVIEW, however each consecutive test on the same pin shows a random input location in LabVIEW (i.e. a different light goes on each time I test the pin location). Question, Is your product compatible with LabVIEW in a digital input. It appears to be compatible with digital output.
