Issue Details

I want to use the 16 differential Analog Inputs (AI) channels of my PCIe-6353, but when I select the AI from AI0 to AI16 and run my program, I receive the error -200077 shown below.

Error -200077 occurred at DAQx Create Channel (AI-Voltage-Basic).vi:1780001
Possible reason(s);
Requested value is not a supported value for this property. The property value may be invalid because it conflicts with another property.


The PCIe-6353 card has 32 Single Ended Analog Inputs distributed in front connectors (16 AI per connector). If you want to use Differential inputs, you will need 2 Single Ended AI pins for each Differential input. This means that there are 8 differential inputs per connector. To select all the differential channels, both connectors must be taken into account. In Connector 1, you will find the analog inputs from AI0 to AI7 and in Connector 2 there are inputs AI16 to AI23. See image below.
