only DIO working not the analog IOs in 6031E

[jey]

In the 6031E mutifunction DAQ,everything was working perfectly until recently,but suddenly all analog IO channels failed with no signal in or out.This happened when I started using one of the counters for measuring RPM.Digital IOs are working well.I am using  10 channels for analog inputs for different sensor readings and 2 analog outputs for controlling two tunnel Fan RPMs.Self test of this board has been passed.

1.I  am suspecting the board has become faulty.Is it so? But Digital IOs are functioning.How can i troubleshoot a card whether  its front end features gone bad or not  since they are passing their self tests ?

2.The card becomes hot even if it runs for  nearly ten minutes. why ?

3.I suppose analog IOs,Counters and Digital IOs are independent entities in a card.Am i right?

3.I am suspecting other supporting cards also got affected like PCI 1411 Image acquisition card as it now showing " can not find any recognizable video source".Why  these things happened suddenly as i am using these cards nearly for 3 months?

 Kindly let me know the reasons

Regards,

Jay

Dear Jay,

1. Have you tried the board in a different PCI slot or a different computer? If the board works in a different slot and computer, but doesn't pass, you should send it in for repair.

2. My board warms up, but doesn't get hot. The diagnostic will tell you if it is heating up because it is faulty.

3. Analog, digital, and counters all share the same ground plane.

4. Did you change anything with the software? What versions of the different kinds of software are you using?

Please let me know if you have any questions. Have a great day!

Sincerely,

Marni S.
