I am using NI-DAQmx with support for LabVIEW NXG. How can I acquire data from more than one NI-DAQmx channel within the same task? Can I select multiple channels or ports?

Can I read from multiple DAQ channels in one task with LabVIEW NXG?


There are four ways to do this, outlined below: 
LabVIEW NXG Measurement Panels

  1. Select the NI-DAQmx task within LabVIEW NXG.
  2. Click Create New Input button.
  3. Use <CTRL> and click the mouse pointer to highlight additional channels.


NI-DAQmx API (Method 1)

  1. Select the DAQmx Physical Channel control or constant and make sure Allow Multiple Names is enabled in the Items tab.
  2. Select the dropdown from a DAQmx Physical Channel control or constant.
  3. Use <CTRL>  and click the mouse pointer to highlight multiple channels.


NI-DAQmx API (Method 2)

  1. Select the DAQmx Physical Channel control or constant and make sure Allow Multiple Names is enabled in the ​Items tab.
  2. Type directly into the DAQmx control or constant. The syntax is described here in the online DAQmx help: Physical Channel Syntax.


Create a Virtual Task in Measurement and Automation Explorer (MAX)

  1. Select the NI-DAQmx task within MAX.
  2. Click the blue "+" button.
  3. Use <CTRL> and click the mouse pointer to highlight multiple channels.
