Modes and Front Panel LED Blink Patterns
The following table lists the modes and blink patterns for the front panel LEDs associated with each
mode. These patterns are not evident until after the unit is powered.
Port Assignments and Functionality
The Port Assignments are as follows:
AXlink Port and LED
Both the NI-700 and NI-900 have an AXlink port and adjacent status LED (FIG. 1). 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.
