I use winxpsp2 with LV8.2, DAQmx8.6. With Measurement and Automation Explorer, the card can write out 5V properly, but it seems that each one pin of the 3 ports couldn't read 0V and the LEDS always high (light-on).
I also tried to configure pin0 of portb as output and pin0 of portc as input in LV and connect them together, the read out data is always high.
Since the card is not supported by DAQ Diagnostic Utility. Any way to check if the card is broken?
