I'm using a PC-TIO-10.When I write HIGH at the Digital port B and measure the signals, I'm getting 4,10 V instead of 5V.I tried to uninstall the Card but the problem persists. What should I do ?

The computer is a COMPAQ EC433 MHz 32 MBytes of ram running Win98.

I don't think you're supposed to get 5 volts out. I believe the outputs are TTL compatible in which case the 4.1 volts is about right. Check the specifications.

The other port (port A) gives me 4.99V for all the signals.

According to the NI catalog - "One port has low-drive, CMOS-compatible outputs, while the other port has high-drive, totem pole, 5V/TTL-compatible outputs that are suitable for controlling Darlington switches." This says to me that your port B outputs are different than you port A. Again, check the user's manual that came with the board to verify the specifications.
