Aside from manually selecting crosspoints, you can choose the Autoselect option both in case of audio and
video ports. Three types of Autoselect is available:
▪ First detect mode: selected input port is kept connected to the output while it has an active signal.
▪ Priority detect mode: it is always the highest priority active input is selected to transmit.
▪ Last detect mode: it is always the last attached input is selected to transmit.
