4.5. The Autoselect Feature
Beside of manual selecting of 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: selected input port is kept connected to the output while it has an active signal.
▪ Priority detect mode: always the highest priority active input is selected to transmit.
▪ Last detect mode: always the last attached input is selected to transmit.

Automatic Input Selection - Example
Laptop PC Blu-ray player
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.
Settings
▪ HDMI output: Set the Autoselect to Enabled. The Autoselect mode is Priority detect. The priorities are the
followings (the lowest number means the highest priority):
Source device
Laptop
PC
Blu-ray player (via a TPS transmitter)
Priorities can be set in Lightware Device Controller software, see related settings in the
section.
