Preparing Your Panel For Pass-Thru Control (Using The Nxa-Avb/Rgb Breakout Box) - AMX NXD-1200VG Operation/Reference Manual

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.

Preparing your panel for Pass-Thru Control (using the NXA-AVB/RGB Breakout Box)

Pass-thru control allows the NXA-AVB/RGB to act as a control bridge between the USB input signals (coming from a
touch panel via the NXA-RGB card) and a target computer.

The pass-thru is routed from the USB Input device, through the panel, then through internal NXA-RGB card
and to the front RGB RJ-45 connector on the NXA-AVB/RGB. From there the signal is routed through the
rear USB port on the breakout box and finally to the target PC. Refer to FIG. 7 for a visual representation.
Pass-thru must be enabled to control devices through the NXA-RGB card when using
USB-compatible control devices.
Refer to the following commands to enable pass-thru on the RGB card: ^MPS on
page 202 for Mouse pass-thru and ^KPS on page 202 for the keyboard
pass-thru.
The two available USB input connections on the touch panel can be used to provide either Keyboard
and/or Mouse signals between the PC and the panel. You are no longer limited to one mouse and one keyboard. You can
use USB hubs and multiple mice/keyboards in any configuration.
When setting up pass-thru computer control its important to focus on the following areas:
1.
Properly connect the NXA-AVB/RGB to both a target PC and touch panel using the appropriate cabling. Refer to
the following Wiring for Pass-Thru Computer Control section on page 20 for more detailed information.
2.
Enable pass-thru via the use of either the ^MPS or ^KPS commands (page 202).
3.
Set up a touch panel page (via TPDesign4) with the necessary Video Fill > (Component/RGB video) properties
selected.
Video Fill allows you to select from a drop-down list of video formats that are supported by the touch panel
specified in your project. VG-Series Modero panels (1200VG, 1500VG and 1700VG) support Composite video,
Component/RGB video, and Streaming video formats.


Note that Streaming Source is only available as a Video Fill option if the project
specifies a touch panel that supports streaming video (NXD/NXT-1200VG,
NXD/NXT-1500VG, and NXD/NXT-1700VG only).
4.
Set up a touch panel page (via TPDesign4) with the necessary Video Touch Pass-thru property (yes) selected.
Video Pass-Thru allows you to pass touch/control information from a touch input device (touch panel, mouse or
keyboard) through an NXA-AVB/RGB to a controlled device with video-out capabilities. Select Yes from the drop-
down menu to enable video pass-thru (disabled by default). This feature is also used in conjunction with the ^MPS
(mouse pass-thru) and ^KPS (keyboard pass-thru) commands.

Selecting Component/RGB allows you to route a video signal from your computer through the NXA-AVB/
RGB and then to the panel.
Selecting Streaming Video requires that you enter the URL or IP Address of the server that will provide the
video stream.
