10 NXR-ZGW-PRO NetLinx ZigBee Pro Gateway & NXR-ZRP-PRO NetLinx ZigBee Pro Repeater
Connecting Power to the NXR-ZGW-PRO and NXR-ZRP-PRO
The NXR-ZGW-PRO receives power via either PoE or 2-pin 3.5 mm mini-captive wire connection, while the
NXR-ZRP-PRO only utilizes the 2-pin 3.5 mm mini-captive wire connection.
If PoE is used, the NXR-ZGW-PRO will draw power through the CAT5 Ethernet cable, thereby allowing it to
be installed in areas without extra wiring for power (see
Determining the Power Source
section on page 10).
Determining the Power Source
The ability to choose a power supply option increases the availability of deployment locations. In addition, the
NXR-ZGW-PRO facilitates installation into areas previously without power, as it is not necessary to run
electrical wires to the device.
Based upon location and the availability of electricity, select one of the two following methods for power:

2-pin 3.5mm captive-wire connector - Prepare the captive wire pair and insert it into the
connector. See
Preparing Captive Wires for the 2-pin 3.5mm Captive Wire PWR Connector
section
on page 10.
This is the only power option for the NXR-ZRP-PRO.

Power Over Ethernet (PoE) (NXD-ZGW-PRO only) - If no electrical outlet is available, you can
plug one end of the CAT5 Ethernet cable into the RJ-45 jack of the NXR-ZGW-PRO and plug the
other end of the CAT5 cable into PoE supply equipment (
this unit must be 802.3af compliant ).
The NXR-ZGW is rated as a PoE Class 2 device that consumes about 2.5W, about 50mA to 60mA
at 48V.
Preparing Captive Wires for the 2-pin 3.5mm Captive Wire PWR Connector
If the 2-pin 3.5 mm mini-captive wire is selected, the following steps are necessary:
You will need a wire stripper and flat-blade screwdriver to prepare and connect the captive wires.
1.
Strip 0.25 inch (6.35 mm) of wire insulation off all wires.
2.
Insert each wire into the appropriate opening on the connector according to the wiring diagrams and
connector types described in this section.
3.
Turn the screws clockwise to secure the wires in the connector. Do not over-torque the screws; doing so
can bend the seating pins and damage the connector.
Using the PSN NetLinx connector for power
The PWR and GND cable from the 12 VDC power supply must be connected to the corresponding location on
the 2-pin 3.5 mm mini-captive wire connector (FIG. 6).
1.
Insert the PWR and GND wires on the terminal end of a PSN 2-pin 3.5 mm mini-captive wire cable.
Match the wiring locations of the +/- on both the power supply and the terminal connector.
2.
Tighten the clamp to secure the two wires. Do not over-torque the screws, as doing so may strip the
threads and damage the connector.
3.
Verify the connection of the 2-pin 3.5 mm mini-captive wire to the power supply.
When connecting both Ethernet and mini-captive wire connections to the NXR-ZGW-
PRO, PoE is overridden by the captive wire connection. PoE is only engaged if
Ethernet is the only power source available to the device.
