Setting 1208FS analog input port - Single end vs differential



It is not stated in the 1208FS user manual where the configuration of the analog input ports is configured, single ended versus differential.  Is this configuration determined solely via Instacal or can this configuration be set/changed via USB command?

Please clarify.

Hello @SunnA

Setting the analog inputs to SE/DI was deemed a software function so it is not documented in the hardware manual.

This can be configured in InstaCal and also is documented in the Universal Library manual https://www.mccdaq.com/pdfs/manuals/Mcculw_WebHelp/ULStart.htm

From the Contents, Go to Hardware Reference >> Analog Input Hardware >> USB-1208FS and USB-1408FS topic.

Scroll down to the Configuration section, and locate "Input Mode".  From the help file:

UL: cbAInputMode()

UL for .NET: AInputMode()

Python for Windows: a_input_mode


I don't know what IDE you are looking for but here is an example for VB.NET or C#.NET (add a ";"):



Note:  This feature is not supported when using DASYLab nor LabVIEW with ULx for NI LabVIEW.  Analog input channel configuration can only be performed via InstaCal.
