Connections and Wiring
9 NI-3101-SIG Signature Series NetLinx Integrated Controller
The AXlink port can be used to supply power to downstream AXlink-compatible devices, so long as both the
power required is LESS THAN 2 Amps total and the external power supply feeding the device has the
necessary power capability.
Wiring Guidelines
The Integrated Controllers use a 12 VDC-compliant power supply to provide power through the rear
2-pin 3.5 mm mini-Phoenix PWR connector, or through the 4-pin 3.5 mm mini-Phoenix (female) captive-wire
connector used for data communication and power transfer. Use the power requirements referenced in the
product’s Specifications table to determine the power draw.
The incoming PWR and GND cable from the power supply must be connected to the corresponding locations
within the PWR connector.
Wiring length guidelines
Refer to the following table for the wiring length information used with the NI-3101:
Preparing captive wires
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 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. Tighten the screws to secure the wire in the connector. Do not tighten the screws excessively. Doing so
may strip the threads and damage the connector.
Wiring a power connection
To use the 2-pin 3.5 mm mini-Phoenix connector with a 12 VDC-compliant power supply, the incoming PWR
and GND cables from the external source must be connected to their corresponding locations on the connector
(FIG. 4).
1. Insert the PWR and GND wires on the terminal end of the 2-pin 3.5 mm mini-Phoenix 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 tighten the screws excessively; doing so may strip the
threads and damage the connector.
3. Verify the connection of the 2-pin 3.5 mm mini-Phoenix to the external 12 VDC-compliant power supply.
Use only one power source for the device at a time. Using both the 2-pin mini-
Phoenix PWR connector and the 4-pin mini-Phoenix AXLink connector at the same
time may cause permanent damage to the device.
Apply power to the device only after installation is complete.
