AMX NXI-x000 Series AXlink Port and LED, Wiring Guidelines, blink per second - Normal operation

Connections and Wiring

AXlink Port and LED

All NI units have an AXlink port and adjacent status LED (FIG. 1). This port allows the NI to support AMX Legacy AXlink devices such as G3 touch panels (ex: CP4/A) and PosiTrack Pilot devices. A green LED shows AXlink data activity. When the AXlink port is operating normally, blink patterns include:

Off - No power, or the controller is not functioning properly

1 blink per second - Normal operation.

3 blinks per second - AXlink bus error. Check all AXlink bus connections.

FIG. 1 AXlink connector and LED

The AXlink port can be used to supply power to downstream AXlink-compatible devices as long as both the power required is LESS THAN 2 Amps total and the external power supply feeding the NI unit has the necessary power capability.

Wiring Guidelines

The Integrated Controllers use a 12 VDC-compliant power supply to provide power through the rear 2- pin 3.5 mm mini-Phoenix PWR connector. Use the power requirements referenced in the product’s Specifications table to determine the power draw.

The incoming PWR and GND cable from the power supply must be connected to the corresponding locations within the PWR connector.

This unit should only have one source of incoming power.

Using more than one source of power to the Controller can result in damage to the internal components and a possible burn out.

Apply power to the unit only after installation is complete.
