Channels

All data input into VCM Scanner is defined by "channels."

If you want to display any value on any layout display (Gauge/Graph/Chart vs. Time), you must have a channel that supplies the data.
If you want to use a Math Parameter, each variable used in the math parameter will also require a channel to supply the data.

Many channels are pre-defined (you see some of these in action when you do a quick scan without adding channels). However, adding an external sensor input or an input based on a parameter that the vehicle's controller does not broadcast will require that a channel be added to support the input.

The Channels list displays the currently-defined channels. Use this interface add, configure, and remove channels. See Using the Channels List for more information.
