MIO-16DE running with XP problem

[edinsofty1]

Just upgraded one of our test sites to XP (from NT) and encountered a strange problem with using the MIO-16DE card to acquire voltages. There are a number of tests currently used that read voltages from various test points on a UUT fine, but I added a new test to simply measure a voltage on a new test point, which is meant to be 7.5V. Using a DMM at the UUT end of the cable, 7.5V is measured. Using NIMax, it measures 7.5V through the Test Panel. Using LabWindows CVI (using a copy of working functions), it always measures 4.998V. Help!

Using the PCI6071 card to acquire voltages.

MIO-16DE

An error status is returned when using the SCAN_OP function : status -10455 (No DMA channel available on the MIO-16DE card)

Check the max and min for the 6071. Not sure about the error for the MIO-16DE card.

The card is initialised for +/- 10V limits
