FIG. 21 Mini-Phoenix connector wiring diagram (direct data and power)
To use the 4-pin 3.5 mm mini-Phoenix (male) 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 central controller. FIG. 22 shows the wiring diagram:

WARNING! 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.
