AxLink Port and LED

The AxLink port and adjacent status LED on the front panel allows the NXC-ME260/64 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.

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 ME260/64 has the necessary power capability.

Wiring Guidelines

Use a 12 VDC-compliant power supply to provide power to the ME250/64 via the 2-pin 3.5 mm mini-Phoenix PWR connector on the
rear panel. Use the power requirements information described 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.
CAUTION:
result in damage to the internal components and a possible burn out. Apply power to the unit only after installation is complete.

Wiring Length Guidelines

Refer to the following table for the wiring length guidelines based on wire size (gauge):

Preparing Captive Wires

You will need a wire stripper and flat-blade screwdriver to prepare and connect the captive wires.
NOTE: Never pre-tin wires for compression-type connections.
1. Strip 0.25 inch (6.35 mm) of insulation off all wires.
2. Insert each wire into the appropriate opening on the connector (according to the wiring diagrams and connector types
described in this section).
3. Tighten the screws to secure the wire in the connector. Do not tighten the screws excessively doing so may strip the threads
and damage the connector.
