The Autoselect Feature
Beside manually selecting crosspoints, you can choose the Autoselect option both in case of audio and
video ports.
There are three types of Autoselect as follows:
▪
First detect mode
: the selected input port is connected to the output while it has an active signal.
▪
Priority detect mode
: it is always the highest priority active input that is selected to be transmited.
▪
Last detect mode
: it is always the last attached input that is selected to be transmitted.

Automatic Input Selection - Example
The Concept
If there is no other source connecting to the matrix, only the Laptop, the source on HDMI input 3 will be
automatically switched to the HDMI output. If the Laptop and the PC are also connected to the matrix, the
source on the HDMI input 2 will be switched to the HDMI output. If the Blu-ray player is connected through
the TPS transmitter, TPS input 1 will be switched to the HDMI output – independently of the presence of the
other video signals.
