QUICK START GUIDE
N7142 Video Presentation Switcher
Overview
The NMX-PRS-N7142 Video Presentation Switcher incorporates low-latency
networked AV video distribution. The unit has six local inputs and two
independent outputs (both of the outputs are mirrored).
There are two models of the N7142. The NMX-PRS-N7142 is the base
presentation switcher, with two available Networked AV slots that can be
populated with Encoder and Decoder cards as required by the application.
The NMX-PRS-N7142-23 is an identical presentation switcher, pre-
populated with one N2312 Encoder card and one N2322 Decoder card.

Installing the N7142 Video Switcher
Follow the steps below for initial setup of the N7142.
1. Connect a monitor (that supports 1080p60) to one of the VIDEO
OUTPUT connectors on the rear of the unit.
2. If networked AV cards are installed:
• Connect the network cables from the cards to the built-in switch.
• Connect the HDMI output on the installed Decoder to an N7142 HDMI
input.
• Connect the HDMI input on the installed Encoder to an N7142 HDMI
output.
NOTE: If the AV card is connected to one of the three PoE+ ports, it will be
powered automatically once the network connection is established. If not,
then connect the two-pin phoenix adapter from the 12VDC output connector
of the N7142 to the 12VDC input connector on the card.
CAUTION: Do not run wiring that is connected to a PoE PSE port outside of
the building where the PSE resides. It is for intra-building use only.
3. Connect all other video sources, displays, etc. as necessary for your
application.
4. Apply power to the N7142 unit using the power cable provided.
5. Once the unit completes the boot up process and the attached monitor
displays the AMX logo, press the MENU button to access the On-Screen
Display (OSD) setup menu. The Quick Setup page displays (see FIG. 2).
6. Use the corresponding arrow and ENTER keys (on the front panel) to
assign the N7142 a Name.
