AXlink Port and LED

All NI units have an AXlink port and adjacent status LED (FIG. 3). This 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:

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.

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.
