The IRX-DM+ (FG458-10/11) is in a UniMount enclosure that fits into most US-style single-gang enclosures. The IRX-DM+ works with AMX 38 kHz or 455 kHz IR transmitters. Note: The IRX-SM+ swivel-mount version is also available for wall or ceiling installations.

FIG. 3 illustrates the configuration of the jumper. 455 kHz Pin 1 2 1 38 kHz Pin 2 3 Pin 3 FIG. 3 Receive frequency jumper settings Note: The unit will not operate until JP1 is configured for either 38 kHz or 455 kHz. • To receive 38 kHz, position the JP1 jumper on pins 1 and 2 (closer to the Phoenix connector). • To receive 455 kHz (default setting), position the JP1 jumper on pins 2 and 3 (away from the Phoenix connector). Wiring the IR Sensors The IRX-DM+ uses a 4-pin Phoenix connector for power and data. If the distance between the receiver and Central Controller exceeds power consumption limits, you can connect a local 12 VDC power supply to the Phoenix connector. Preparing captive wires You will need a wire stripper and a flat-blade screwdriver to prepare the captive wires: 1. Strip 0.25 inch (6.35 mm) of wire insulation off all wires. 2. Insert each wire into the appropriate opening on the connector according to the wiring diagrams in this section. 3. Turn the flat-head screws clockwise to secure the wire in the connector. Note: Do not over-torque the screw. Doing so can bend the seating pin. Wiring Guidelines The IRX-DM+ requires 12 VDC power to operate properly. The power is supplied by the AMX system's connection cable. The maximum wiring distance between the Central Controller and the receiver is 200 feet (60.96 m). Connections and Wiring Wiring the IRX-DM+ or IRX-SM+ to the AMX IR Receiver Wire the IR sensor to the AMX IR receiver as shown in FIG. 4.

For additional information, refer to the reference guides or instruction manuals for those AMX products. Checking IR Data Status Locate the red IR Data LED on the front of the unit. Point the system's AMX transmitter towards the sensor and press a button. The IR Data LED lights when the unit receives data. If the IR Data LED on the unit does not light: • Verify that the transmit LED on the transmitter lights when you press a button. • Check the wiring to the unit. • Verify that the transmitter frequency is properly configured. To the external sensor input connector Top view Top view Mounting the IRX-DM+ 1. For wall or podium mounting (FIG. 5), AMX recommends mounting the IRX-DM+ in a standard 1-gang wallbox with a minimum internal clearance of 1 3/4" (W) x 2 5/8" (H) x 1 5/8" (D). 2. Gently remove the bezel from the wallplate. 3. Place the panel in the wallbox and align the screw holes with the mounting holes on the panel. 4. Turn the unit over and locate the Phoenix connector. 5. Fasten the panel to the wallbox using the screws supplied with the panel. 6. Snap the wallplate back on the bezel. wall plate bezel FIG. 5 IRX-DM+ Mounting Dimensions AMX Corporation reserves the right to alter specifications without notice at any time. 93-0458-10 REV: B For full warranty information, refer to the AMX Instruction Manual(s) associated with your Product(s). 042-004-2749 11/04 ©2004 AMX Corporation.
