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:
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.
