NI-2100/3100/4100 - Hardware Reference Guide
Port Assignments and Functionality
The Port Assignments are as follows:
AxLink Port and LED
All NI Controllers have an AxLink port and adjacent status LED (FIG. 8). The AxLink port allows the NI to support AMX Legacy
AxLink devices such as G3 touch panels (
ex: CP4/A
) and PosiTrack Pilot devices. A green LED shows AxLink data activity. When the
AxLink port is operating normally, blink patterns include the following:
Off
- No power, or the controller is not functioning properly.
1 blink per second
- Normal operation.
3 blinks per second
- AxLink bus error. Check all AxLink bus connections.
With the AxLink port, you can supply power to downstream AxLink-compatible devices as long as both the power required is LESS
THAN 2 Amps total and the external power supply feeding the NI unit 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. 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.
CAUTION:
This unit should only have one source of incoming power. Using more than one source of power to the Controller can
result in damage to the internal components and a possible burn out. Apply power to the unit only after installation is complete.
