Enova DVX-3150HD/3155HD All-in-One Presentation Switcher Operation/Reference Guide
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 All-In-One Presentation Switcher. FIG. 48 shows the wiring diagram.
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.

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.
