Projector HDMI input joins

Screen: Room Devices — a room's TV & audio card, Projector box — the Action / Type / Join table.

What it is

One box per HDMI n row (named after the source chosen for that port): the digital join that switches the projector to that input. There are as many rows as HDMI ports.

What to enter

Type the join for each input.

The box turns red and refuses a number above the processor's digital limit. A number already used on that processor opens a box with Cancel pick another and Use it anyway.

What it changes

In the house: The project saves it as you type. At the next Save & Deploy the app presses it when that source is picked for the projector.

In the app: Picking the source in the app switches the projector's input.

If it goes wrong

• 0 on a port: picking that source does not switch the projector.
