IRX-PP38 NetLinx Plasma-Proof IR Sensor

IRX-PP38 IR Sensor Overview

The IRX-PP38 IR sensor is designed to provide optimum functionality for IR
reception and transfer to high-end devices such as plasma televisions which
sometimes can have issues with other receivers. The IRX-PP38 is compatible
with AMX’s newest NI-700 and NI-900 NetLinx Master Controllers.

IRX-PP38 Plasma-Proof Components

The terminal IR sensor is wired to the main unit via a 34-inch long (2.83 feet)
cable. The main unit provides both an on-board blue LED (to confirm IR
reception) and a 3-pin mini-Phoenix connection used to wire the sensor to the IR
RX (sensor) port on the back of a compatible AMX device (such as the
NI-700/900 Controllers).

• 0.56" x 3.88" x 1.06" (1.43 cm x 9.84 cm x 2.70 cm)

interference from fluorescent lamps and plasma displays.

• Supports an AMX IR frequency of 38 KHz.

secured to a surface near the target device.

• Maximum wire distance to an NI700/900: 200 feet (60.96
meters)

• IR Feedback LED (blue). LED illuminates when it receives an IR
signal.

• 3-pin mini-Phoenix connector. Wires the IRX-PP38 to the IR
receive port on compatible AMX devices.

• Terminal IR sensor. This sensor adheres to any object within the
line of sight of your remote and enables you to receive control
signals from either an IR Emitter or a hand-held remote control.

• Two screw openings. These openings (located at opposite ends
of the main IR sensor) are used to secure the unit. This portion
of the IRX-PP38 is kept out of sight whereas the terminal IR
sensor adheres to the IR window.

• Adhesive foam (pre-installed onto the terminal IR sensor)

Installation Overview

Note: Never pre-tin wires for compression-type connections.

1. Strip 0.25 inch (6.35 mm) of insulation off all wires.

2. Insert each wire into the appropriate opening on the IRX-PP38 connector
according to the wiring diagrams and connector types described in FIG. 2.

Note: Always match the wiring on each end of these connections. If you
are using a red insulated wire to supply power on one connector, make
sure you thread this same wire into the PWR connector at the other end.

3. Insert each wire into the appropriate opening on the NI’s rear IR RX connector, according to the wiring diagrams and connector types described in FIG. 2.

4. Tighten the screws to secure the wires into their respective connectors.

Note: Do not tighten the screws excessively. Doing so may strip the
threads and damage the connector.

5. Remove the cover off the adhesive foam on the IR sensor.

6. Adhere the adhesive flat side of the terminal plasma-proof IR sensor to any
object within the line of sight of your remote. Make sure the raised oval side
of the terminal IR sensor (opaque) is facing outwards and can receive the
IR signal from the remote (such as a Mio R-1).

Wiring the IRX-PP38 IR Sensor

The maximum wiring distance between the IRX and a target NI Controller (such
as the NI-700 and NI-900) is 200 feet (60.96 meters). FIG. 2 displays a sample
wiring diagram which shows how you can wire a single Controller for
communication to two separate IRX IR sensors.

FIG. 3 Equipment wiring overview

You can use the IRX-PP38 in any installation where a previous AMX IRX device
was used. For illustration purposes, the NI-900 is used in this document’s wiring
diagrams.

Note: The IRX- PP38 uses the IR input port on an NI-700/900 controller (one
IRX-PP38 per NI-700/900).
