Board Topologies

A topology describes the static assignment of cameras to the frame grabber connectors.

The topology used in the application is declared by the user with the MultiCam parameter BoardTopology at the beginning of the application code before creating any channel.

If the application does not use all the board resources, the user must select a topology that encompasses the needed connectivity.

The value of the BoardTopology parameter is a set of codes separated by an underscore, indicating the kind of camera linked to the connectors.
