Wiring the NXA-AVB/RGB Connectors and Cables

The inputs and outputs on the breakout box are separated into front and rear connectors. The rear connectors are used to input external signals. The front connectors are used to communicate signals between the NXA-AVB/RGB and a target Modero panel. FIG. 4 provides a layout of the wiring connections on both sides of the breakout box. Power should be applied to the

NXA-AVB/RGB only after all connections have been secured onto both the breakout box and the target panel.

between the red, green, and blue video signals. Therefore, for longer cable runs, the video quality will be much higher using the Belden VideoTwist 7987 cable versus standard CAT5 (or other Ethernet compliant cables).

Master’s connection information

FIG. 4 NXA-AVB/RGB Breakout Box connector wiring diagram

Use the NXA-MTC/RGB cable to provide both communication and 10/100 network connectivity between the target panel, NXA-AVB/RGB, NetLinx Master, and the network.

The RJ-45 connector is used to route the signals connected to the RGB / Component input port on the rear of the AVB/RGB Breakout Box to the VG-Series Modero panel. Standard CAT5 cable can be used for this connection with short cable runs under 50 feet (15.24 m). For cable runs over 50 feet (15.24 m), AMX recommends using the Belden Brilliance VideoTwist 7987. This Belden cable is not CAT5 compliant, but is designed to control skew
