Touch Panel Accessories

•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.

•AUDIO IN:6-pin 3.5 mm 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.
• USB:	Type-B USB device port input connector for pass-thru computer
	control. This port provides two-way signal between the keyboard and
	mouse (connected to the rear/side USB connectors on the Modero
	panel) through the front RGB connector on the breakout box, out the
	rear USB Type-B connector, and then to/from the connected
	computer.
• PWR:	2-pin 3.5 mm 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/RGB
	(rear power connector through to the front power connector).

•ETHERNET:RJ-45 connector routes data to the G4 panel through the front Ethernet port. These connections use a standard CAT5 Ethernet cable to provide communication between the target panel, box, and Master.

•Video In BNCs: Feeds either Composite/S-Video Luma or S-Video Chroma signals into the NXA-AVB/RGB. This feed is then redirected out to a Modero panel through the front Audio/Video CAT5 port.

Note: Although the NXA-AVB/RGB Breakout Box can accept either a Composite or S-Video input signal type, only one input source can be used at a time. This unit does not auto-detect the incoming signal type. Using S-Video would require a cable split and a simultaneous connection to both the COMP/Y and C connectors (which would prevent an additional Composite signal from being fed into the unit). A user should not try to connect two Composite video signal cables to the COMP/Y and C connectors.

Wiring the NXA-AVB/RGB 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.
