AMX NXT/NXD-1200V Wiring the NXA-AVB/ETHERNET Connectors and Cables, Wiring for Balanced Audio

Wiring the NXA-AVB/ETHERNET 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/ETHERNET and a target Modero panel. FIG. 4 provides a layout of the wiring connection both into and from the breakout box. Power should be applied to the NXA-AVB/ETHERNET only after all connections have been

secured onto both the breakout box and the target panel.

Modero Setup and System Connection

1.Carefully remove the panel from the shipping box, peel the protective plastic cover from the LCD and apply power to the panel.

2.From below the LCD, press the grey Front Setup Access button for

6 seconds (passing-over the Setup page) to access the Calibration setup page and follow the on-screen instructions.

3.Press the grey Firmware Setup Access button for 3 seconds to open the Setup page and touch the on-screen Protected Setup button.

4.Enter the panel password into the keypad (default is 1988).

5.Press the Device Number field to open the on-screen Device Number keypad and enter a value for the panel (default is 10001).

6.Press Done when finished and press the on-screen Reboot button to cycle power to the panel.

7.Repeat step 3 to access the Protected Setup page and touch the System Settings button to open the System Settings page (FIG. 7).

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

Use a standard CAT5 Ethernet cable (connected to the rear of the Table Top Panel or to the side of the Wall Panel) to provide both communication and 10/100 network connectivity between the panel, breakout box, NetLinx Master, and the network. The rear-panel wiring connections are described below (from left to right):

AUDIO IN:	6-pin mini-Phoenix connector, divided into left and right audio chan-
	nels. Each channel is divided into GND, IN+, and IN- terminal cable
	connectors (2 sets of 3 for each channel).
MIC OUT:	4-pin mini-Phoenix connector, divided into GND, OUT-, and OUT+
	terminal connectors.
Video In BNCs:	Feeds either Composite/S-Video Luma or S-Video Chroma signals
	into the NXA-AVB/ETHERNET. This feed is then redirected out to a
	Modero panel through the front
	Audio/Video CAT5 port.
ETHERNET:	RJ-45 connector routes data to the G4 touch panel through the front
	Ethernet port. These connections use a standard CAT5 Ethernet
	cable to provide communication between the target touch panel,
	Breakout Box, and NetLinx Master.
PWR	2-pin mini-Phoenix connector that connects to a PSN power supply.
	This port can be used to provide power to a Modero panel by sending
	it through the
	NXA-AVB/ETHERNET (rear power connector through to the front
	power connector).
