I need direction on troubleshooting NI4350 ISA board.

[Paul Nelson]

Embedded PC in Environmental chamber. using LabVIEW 5.0 to read Thermocouples on channels 2-9, and voltages on channels 10-14. VI was working, but now is not. I can read Thermocouples or voltages fine, but not both. When I have a group of thermocouples and a group of voltage channels, the TC readings indicate open and the System hangs. I have been testing with "NI435x Getting Started Multiple Transducers Continuous.vi".
Any help greatly appreciated.

Paul;

The best way to test this board is by using the Measurement and Automation Explorer (MAX) Software. By using MAX you will be isolating Labview out of the circuit and test only the hardware.
Hope this helps.

Thanks for the response.
I found that the computer may have been subjected to a number of power failure crashes. The BIOS was set for an automatic restart after power failure.
Testing the board in MAX indicates that the board is good. I next want to re-install LabVIEW (5.0)and NI-DAQ(6.5). I may also test the board in another Test computer.
Thanks for your help,
Paul
