Analog input voltage readings.

[Avicicont]

I have my PCI-1802 connected to 4 analog pressure sensors at channels 0-3.  In my program, the 4 analog channels are connected to digital meters to read the voltage value.  The program works correctly for approx. 30 seconds, then the values for channels 0&1 become 2&3 and channels 2&3 become 0&1.  After 30 seconds the values will return to normal.  Any help is appreciated.

I believe that you need to contact your reseller. You may be sampling too fast for DASYLab to empty the driver buffers.
There may be an updated driver, or they may have other advice.

Hello Antonio,

Thank you for contacting National Instruments. This forum is oriented toward support with issues in DASYlab using National Instruments hardware.  It appears, however, that the PCI-1802 is not a National Instruments product.  This being the case, there are several options for you to recieve the best support for your issue.  cj is correct, your DASYlab distributor would be a good contact, as would the MCC Technical Support group at 508-946-5100 or techsupport@mccdaq.com.  You could also try one of the other DASYlab forums.  I hope this helps point you in the right direction.

Hello Antonio,

the PCI-1802 device is a product from ICP DAS Co., Ltd. Please contact the www.icpdas.com support in Taiwan for your question. The ICP DAS DASYLab driver is not from National Instruments. The "driver toolkit" driver is designed, created and supported from ICP DAS.

Best regards,
