configuration, or another special configuration, adjust the options on the
Cabling
tab.

Configure Channels and Tasks
A
physical channel
is a terminal or pin at which you can measure or
generate an analog or digital signal. A
virtual channel
is a collection of
settings that can include a name, a physical channel, input terminal
connections, the type of measurement or generation, and scaling
information. In Traditional NI-DAQ and earlier versions, configuring
virtual channels is an optional way to record which channels are used for
different measurements. In NI-DAQmx, virtual channels are integral to
every measurement.
