Enova DVX-2150HD/2155HD 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 DVX. FIG. 49 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.
