Quick Start Guide

NXA-AVB/ETHERNET Modero® Ethernet/Video Breakout Box

Overview

The NXA-AVB/ETHERNET Breakout Box (FG2254-10) facilitates the installation

and distribution of video, data, and audio to Modero touch panels located up to

200 feet (60.96 m) from the AVB box. This unit accepts either Composite or

S-Video from standard video devices. FIG. 1 shows the NXA-AVB/ETHERNET

Breakout Box.

For more detailed installation and operating instructions, refer to the specific

Modero touch panel instruction manual, available online at www.amx.com.

Specifications

NXA-AVB/ETHERNET Breakout Box

FIG. 1 shows the front and rear connectors on the breakout box.

Note: The breakout box unit can be mounted on either a horizontal flat surface

or into an equipment rack (by removing the front screws and attaching it to an

AC-RK).

Note: The PSN power supply being used on the NXA-AVB/ETHERNET is

dependent on the power requirements of the target touch panel.

Connections and Wiring

A PSN power supply can indirectly provide power to a Modero panel by routing

power through the NXA-AVB/ETHERNET Breakout Box. FIG. 2 shows a sample

wiring configuration using both an indirect or direct PSN power connection for a

video-capable Modero panel. Refer to the online Modero Touch Panel instruction

manuals for connection options.

The NXA-AVB/ETHERNET is an optional accessory for non-video capable

Modero touch panels but can only transfer Audio signals between the Breakout

Box and the target touch panel.

A PSN power supply can also directly provide power through the unit to a target

Modero panel. Refer to the specific Modero touch panel instruction manual for

detailed wiring information. FIG. 3 shows a sample wiring configuration for a

non-video capable Modero panel.

Note: AMX recommends using the above power connection examples when

connecting the breakout box to your touch panel. If you want to attempt another

configuration or if you want to use two power supplies, be sure to avoid any

potential ground loops that may occur in your connection configuration. Ground

loops can cause display errors with your touch panel.

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.

Rear wiring connections:

•AUDIO IN: 6-pin mini-Phoenix connector, divided into left and right audio

channels. Each channel is divided into GND, IN+, and IN- terminal cable

connectors (2 sets of 3 for each channel).

An example of the cable is to strip the ends of 2 RCA audio cables and

insert them into their respective locations on the Audio In port.

Either a balanced (+, -, and GND) or unbalanced (+ and GND) audio

signal can be connected to this input.

•MIC OUT: 4-pin mini-Phoenix connector, divided into GND, OUT-, and

OUT+ terminal connectors.

An example of the cable use for this connector is to strip the terminal ends

of a 3.5mm mini-jack and insert them into their respective locations on the

Mic Out port. This signal can be fed as a Line Level In to either an

amplifier or an AMX VOL card.

Either a balanced (+, -, and GND) or unbalanced (+ and GND) audio

signal can be connected to this output.

• 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. When feeding an A/V signal from the breakout

box to a 1200V-Series, VG-Series, or Table Top CV10 touch panel via an

RJ-45 cable, you must use the appropriate number of CAT5 Suppression

Ferrites (included with the touch panel) on the cable.

•PWR: 2-pin 3.5 mm mini-Phoenix connector 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).

Wiring the NXA-AVB/ETHERNET for Unbalanced Audio

Most domestic audio equipment has unbalanced audio inputs and outputs. This

means that the audio output (left, right, or mono) appears on a single wire, and

is referenced to "0 V" or "Ground". Typical connectors used are RCA "phono"

connectors, DIN plugs/sockets, and 0.25" (6.3mm) or 3.5mm jack plugs/

sockets.

Unbalanced audio is adequate for most domestic environments and for

line-level signals in a typical broadcast studio. Problems may occur if the

signals are carried over long distances, especially if the source and destination

have separate main supplies. Use the following wiring drawing (FIG. 5) to

configure an unbalanced audio connection.

When using unbalanced audio for the AUDIO IN connector (FIG. 5),

the "-" and the "GND" terminals should be connected together and then

connected to the GND of the unbalance audio signal.

When connecting to an unbalanced audio input from the MIC OUT connector

(FIG. 5), wire the "+" terminal to the signal input, and the "GND" terminal to the

signal ground.

Description of Balanced Audio

Professional audio equipment will often use balanced audio inputs and outputs,

usually on 3-pin "XLR" connectors. A balanced audio signal consists of a pair

of wires carrying the audio signal in anti-phase with each other (if one wire

carries a positive voltage, the other carries an equal and opposite negative

voltage).

The advantage of balanced audio over unbalanced audio is its ability to reject

external interference added as the signal is carried over the wire. The receiving

equipment takes the voltage difference between the two wires as the input

signal. Interference will usually get added to both wires equally, and so gets

cancelled by the receiving equipment.

The 3 wires used in a typical XLR lead are often referred to as Ground, Live

(Hot), and Return (Cold). "Live" and "Return" carry the "in-phase" and

"out-of-phase" versions of the audio respectively. The pins of the XLR plug/

socket are as follows:

• X = GROUND

• L = LIVE (Hot)

• R = RETURN (Cold)

When connecting the MIC OUT connector to a balanced audio input (FIG. 6),

use all three audio terminals (+, -, and GND), then connect the "+" terminal to

the "live" signal, the "-" terminal to the "return" signal, and the "GND" terminal

to the ground signal.
