Configuring DAQ-cards may create problems on some PCs, this is probably due to a non fully-compatible support of the PCMCIA bus.
Sometimes it is enough to change the resource settings of the board (interrupt, base address, DMA) to get it work, you can try it.
Follow these steps:
-Insert one board and start the PC
- From the control panel of windows check the resources assigned to the board
- Disable the option automatic resources
- Change the base configuration assigned by default
- Restart the PC and check if the board is still working
- Now insert the second board and let the default resources be assigned to it
Now they both should be working.
Good luck!
