Using the 4-pin mini-Phoenix connector for data with external power

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 device (FIG. 6). Always use a local power supply to power the device.

FIG. 6 4-pin mini-Phoenix connector wiring diagram (using external power source)

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.

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.
