The Rane IR2R and IR2S are collectively known as an IR2. They work in pairs as an accessory to Rane HAL products. The IR2S sends infrared, the IR2R receives it. They work as a pair to provide an automatic way to sense the position of a movable wall or door. Mounting brackets and screws are included.
A single CAT 5e cable for each door connects the IR2 to a dedicated IR Remotes port on the rear of the HAL2 or DR4. For a wiring diagram, see the next page.
When mounted on opposite sides of the door, and wired correctly, green indicators on the IR2R and IR2S are always lit. Only when the door is open and the IR2R is receiving infrared from the sender does the IR2R's amber indicator light. Depending on the IR2 mounting height and your eyeglass prescription, these indicators can usually be viewed from the floor. Note that the HAL need not have a configuration loaded in it for the above functionality to be observed. A powered HAL2 or DR4 is sufficient.
For an IR2 remote to control audio, the IR2 requires a connection to a HAL2, or to a DR4 connected to any HAL. In either case, the HAL must be loaded with a suitable configuration. When doors or movable partitions are opened or closed the IR2 automatically detects this, and the audio system reconfigures itself appropriately and automatically.
Distinguishing the IR2R from the IR2S: Both the send and receive parts have brown and blue wires, but the receiver also has a black wire.
The HAL does not check the IR2 wiring for errors. The IR2R's green indicator flashes when the output is short-circuited. The amber indicator flashes when the signal is marginal, as for a dirty sensor, or if it's too far away. The IR2 will operate up to 1.5 meters (5 feet) apart.
