Tperk,
Once your configuration is setup properly in Measurement & Automation Explorer (MAX) place a Traditional DAQ Channel Control on your front panel and select the Virtual Channel you would like to use from the drop down menu.
If your Virtual Channel does not show up on the list read the following Knowledge Base, which describes how to configure the DAQ Channel Control to show all types of Virtual Channels.
