Wiring and Installation
12 IR Sensors and Receivers
Use a 12 VDC power supply when the distance between the Central Controller and the sensors or
receivers exceeds the limits described in the Wiring Specifications table above. Make sure to
connect only the GND wire on the AXlink connector when using a 12 VDC power supply.
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. 17.
You can wire up to eight IR sensors in parallel to an AXC-RCVI, AMX Television Manager, MX8,
or MX16. 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 sensor.
! Verify that you configured the transmitter for the proper frequency IR transmission.
Checking AXlink status
The AXlink LED lights to indicate AXlink power/data status as follows:
Do not connect the PWR wire to the AXlink connector's PWR (+) terminal on the
Central Controller's side

• One blink per second indicates power is active and AXlink communication is working.
• Two blinks per second indicates the devices specified in the Master program do not match
the devices found.
• Three blinks per second indicates AXlink communication error
• Full on indicates the following conditions:
• There is no AXlink control or activity, but power is on.
