at-mio-16x, cal ref volt. fail, no longer read ai ch's,ni panel ok

[misplacedeskimo]

The current software was working and taking readings for the last 4 or 5 years. When we tried to calibrate the internal reference voltage through software written 5 years ago, it failed and locked the card up. Now I can't take any readings with the card and it returns a 10800 time out error. If I start the NI test panel for the daq card it reads all the channels without a problem. Any ideas as to what got scrambled? Is it in one of the eeproms? How do you reset them to use default settings again?

There are a couple of reasons that you may be getting the 10800 error from your application. The 10800 error is associated with the analog acquisition timing out. Timeouts most commonly occur with triggered analog acquisitions. Your board may no longer be receiving a trigger signal and this is a possible cause for seeing this error. If you have any triggering circuitry check it to make sure that it is indeed producing trigger signals. This would explain why you are able to see the signals in a test-panel (untriggered), but not in LabVIEW (triggered).

Another possible reason that you may have seen this problem relates to the resources assigned to your board. Specifically the IRQ that is assigned to the board. You may want to try manually changing the IRQ o
f the board. For instance if the current IRQ of the board is 12, check for another available IRQ like 7. This IRQ should not be shared by any other device in the system. Since this is an AT board, it needs to have its own individual IRQ. After you successfully change the IRQ of the board see if you can successfully calibrate the board.

If you are using an old version of the NI-DAQ driver, you may want to upgrade to a newer version. The newest driver that supports this board is NI-DAQ 6.1. If you decide to upgrade you driver, just make sure to uninstall your old driver and remove the board from the machine before you install NI-DAQ 6.1.
