Hi
I am developing a module to configure cDAQ modules and acquire data. The module is quite simple.
I have a user selection for channels to be configured.
In this user selection, I am loading the physical channels and if the user wants a Differential input, am disabling the corresponding channel pair. The user will not be able to configure channel 8, if channel 0 is configured for differential input.
I am using a DAQmx property node for physical channels, to select the 'Input Terminal Configuration' using DAQmx Physical channel property.
For my temperature module and voltage input module, it works fine.
However, when I select a 9233 channel, it has only 4 inputs and returns all 'pseudo differential' configuration. But, I can still configure a channel using DAQmx function for accelerometer signals with Differential input. Why is it that i cannot get 'differential' and 'RSE' from the property node when the DAQmx function allows me to select the same?
Please help. Becasue of this mismatch, I am unable to allow the user to select 'Differential' channels from 9233.

The NI 9233 only works with pseudodifferential input configuration. Setting something different results in an error.

Well
Apologies for the delayed reply. However, I realized that and corrected the code to configure 'pseudo differential' input.
I have not updated the forum post after I made the correction to my code.
However, Thank you for the reply.
