Infrared Remote Devices

Wouldn't it be great if the HAL system could sense when movable walls change position and automatically recon-

figure the Room Combine block to reflect those changes? This is exactly what Infrared Remotes bring to the party.

An Infrared (IR) Remote consists of two parts, an IR transmitter that continuously sends an invisible beam of light

and an IR receiver that receives that beam. When the receiver senses the beam of light, the toggle is in one state

(checked) while when the beam is broken the toggle is in the other state (unchecked). If you place a moveable

wall between the IR transmitter and the IR receiver, the HAL system can automatically know when the wall is

open or closed. By linking the IR Remote toggle with a wall toggle in a Room Combine block, the IRRemote can

automatically change the room configuration as the wall opens and closes.

Since an IR Remote port provides a toggle control, you can link this to another toggle control in your con-

figuration to control its behavior. This means that you can use an IR Remote to control any toggle behavior in

your HAL system, not just the state of the walls in a room combine block. For example, you could link the IR

Remote toggle control to the mute toggle in a block or to a toggle preset.

An IR Remote toggle is a read-only control because the IR receiver controls the state of the toggle according to

whether or not it senses the IR light beam. Since a link can only contain a single read-only control participant you

cannot link an IRRemote toggle to another read-only control such as a latching mode Logic In toggle.

IR2 Device

The IR2 is a two piece Infrared transmitter/receiver pair that works together to provide a read-only toggle input

control for the HAL system. The IR2S sends an infrared beam of light and the IR2R receives the beam. When the

IR2R (receiver) senses infrared, the toggle is checked (wall open). The toggle is unchecked when the IR2R doesn't

sense the beam (wall closed).

Both the HAL2 and DR4 provide ports for IRRemotes, which the IR2 connects to via a single CAT 5e cable. The

following picture shows an IR2R/IR2S pair correctly wired to a CAT 5e cable and also the elements of the

remotes.
