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. 6 provides a layout of the wiring connection both into and from the breakout box.
The rear-panel wiring connections are described below (from left to right):
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. 7) to configure an unbalanced audio connection.

NXA-AVB/ETHERNET Breakout Box connector wiring diagram
• 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 this 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 this cable 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.
• PWR: 2-pin mini-Phoenix connector that connects to a 12 VDC-compliant 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).
