AMX Wiring the IRX-DM+ or IRX-SM+ to the AMX IR Receiver, Checking IR Data status

Wiring and Installation

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.

Do not connect the PWR wire to the AXlink connector's PWR (+) terminal on the

Central Controller's side

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.

FIG. 17 Wiring the IR sensor to the AMX receiver

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:

• 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.
	• The Axcess program is not loaded.
