The autoselect mode can be set on output ports for each input with
Lightware Device (LDC) Controller software (see more info about it in
HDMI and TPS Output Port Properties
(see more info about it in Change the Autoselect Mode
INFO: An input port is active if there is a valid signal on it.
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.
The proper priority setting requires fulfill the conditions below:
Match the priority to the input ports. 0 means the highest, 7
▪
means the lowest priority. If two inputs have the same priority
number, the lower port number gets higher priority.
Certain inputs can ignore by clicking the green tick or
▪
write 31 instead of the priority number. This port will
be not scanned. See more details about this setting in
Query the Input Port Priority
▪ Always confirm the settings by clicking on Set priorities button.
Last detect mode: Always the last attached input is selected to transmit.
See the Flowchart of Autoselect Modes in the Appendix chapter.
INFO: Autoselect mode is always disabled on locked output. If the
crosspoint is changed manually, the autoselect function became
also disabled.
