Enova AVX-400 Cat5 Presentation Switcher Operation/Reference Guide
AXLINK
All AVX-400 units have an AxLink port and adjacent status LED (FIG. 11). This port allows the unit to be
controlled from any AxLink Master such as a NetLinx NI Controller. 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.
To use the 4-pin 3.5 mm mini-Phoenix (female) captive-wire connector for data communication and power
transfer, the incoming PWR and GND cable from the 12 VDC-compliant power supply must be connected to
the AxLink cable connector going to the Integrated Controller. FIG. 12 shows the wiring diagram. Always use
a local power supply to power the Integrated Controller unit.
Make sure to connect only the GND wire on the AxLink/PWR connector when using a separate 12 VDC
power supply. Do not connect the PWR wire to the AxLink connector’s PWR (+) opening.

The AVX-400 cannot be powered by this port or use the port to power other devices.

When you connect an external power supply, do not connect the wire from the PWR
terminal (coming from the external device) to the PWR terminal on the Phoenix
connector attached to the Controller unit. Make sure to connect only the AXM, AXP,
and GND wires to the Controller’s Phoenix connector when using an external power
supply.
