AMX NMX-DEC-N2322 Quick Start Guide

QUICK START GUIDE

SVSI N2312/N2322 4K Series

Overview

The NMX-ENC-N2312 Encoder and NMX-DEC-N2322 Decoder provide a
flexible, feature-rich, and simple-to-deploy Digital Media Distribution and
Switching solution which satisfies the most demanding 4K applications with
resolutions up to 4096x2160. Distribution and switching is over standard
gigabit Ethernet networks.

HD signals from the N2312 Encoder are provided as a compressed 200­Mbps stream through the RJ-45 or small-form-pluggable (SFP) connector.

Any source can be sent to multiple displays by routing through appropriate
switches. System scalability may be limited by up-link and stacking
connector bandwidths. Standard features like output scaling, bi-directional
serial, IR, embedded 7.1 audio, and KVM-over-IP extension are included. The
N2312 and N2322 cards are compatible with the N-Series N9206 card cage
for high-density applications.

One USB Mini-B Port

(supported by Encoders)

Two USB Standard-A Ports

(supported by Decoders)

P1 port accepts a 1G SFP fiber transceiver

or a 1G SFP direct attach cable

External power supply: If not using PoE for power, connect a 12V
regulated power supply (part number N9312) to the unit’s two-pin
terminal block plug connector labeled +12V 2A.

network connection.

Externally powered units: If not using PoE, connect the P0 port to
the network using an Ethernet cable, or connect the P1 port to the
network with the appropriate cable (fiber transceiver or direct-attach
cable is required).

NOTE: All switches through which the N2312 stream routes must be
configured to support jumbo frames.

• For video encoding of a digital source, connect the source to the

Encoder’s HDMI IN port using a video cable with an HDMI connector (or
adapter).

• For video encoding of an analog source, connect the source to the

Encoder’s VGA IN port using a video cable with a VGA connector (or
component adapter).

N2322 Decoders

• For video decoding, connect a digital display to the Decoder’s HDMI OUT

port using a video cable with an HDMI connector (or adapter).

• For audio encoding, connect a line level analog audio source to the

Audio input terminal block plug connector, or

• Use the embedded audio from the video source.

N2322 Decoders

• For analog audio decoding, connect a line level analog audio device to

the Audio output terminal block plug connector, or

• Send embedded digital audio (embedded in the HDMI connection) to a
monitor’s speakers.

Establishing Connection

N23X2 devices are shipped with DHCP as their default IP mode. The IP
address is assigned automatically based on the network DHCP server. If no
DHCP server is found, the unit will use Auto IP mode instead (with a default
IP address of 169.254.xxx.xxx).

Before using your N23X2 unit, it must be configured using the free N-Able
device management software. However, you will not be able to configure
units until they are in the same subnet as the host computer.

The sample steps below show how the required changes (to the host
computer’s IP settings) are made in a Windows environment.

Steps for IP address configuration:

1. From the Control Panel > Network and Internet dialog box, select
Network and Sharing Center.

2. Select Change adapter settings.

3. Select the wired interface connected to your AV network.

4. Click the Properties button.

5. Scroll down in the list to the Internet Protocol Version 4 (TCP/IPv4)
option. Highlight it and click the Properties button.

6. Enable the Use the following IP address option, and enter the static IP
address provided to you by your network administrator.

NOTE: If the computer does not need Internet access, you can simply enter a
unique 169.254.xxx.xxx IP address with a 255.255.0.0 Subnet mask. Please
contact your network administrator if you are unsure of how to configure the
existing interface. If the computer has a statically-assigned IP address, click
on the Advanced button. Then click Add to enter a unique 169.254.xxx.xxx
address with a subnet of 255.255.0.0.

Steps for auto discovering devices on the network:

1. Use the host computer to download and install the latest version of N­Able:

PC version - http://www.amx.com/products/N-ABLE-PC.asp
Mac version - http://www.amx.com/products/N-ABLE-MAC.asp

2. Attach your N23X2 unit(s) to the layer-3 network switch.

NOTE: Any switch handling the N23X2 video streams must be configured to
support jumbo frames.

3. Disable the wireless adapter on your computer (it must be hard-wired
to the switch).

4. Connect the host computer to the layer-3 network switch.

5. Open the N-Able application.

If all devices do not appear automatically, click the Auto Discover button on
the Unit Management tab. This issues a broadcast command that will
discover all units even if they are not in the same IP subnet.

Logging in Using N-Able Software

Once the host IP address is configured properly, you can view all discovered
units using the N-Able software. Access the N23X2 units from the following
tabs:

• Unit Management tab - N2300 Encoder/Decoder is listed in the Type

field.

• Video Matrix tab - N23X2 units are found on the N2300 sub-tab of this

screen.

Double-click the unit’s name (in one of the lists mentioned above) to view its
webpage GUI. Configuration options for Encoders and Decoders can be
modified through their webpage. If prompted, enter admin and password
for the default username and password. Once logged in to the webpage, you
can change the username and password (using the options on the unit’s
Settings page). If you would like for N-Able to support auto-login to your
units, make sure N-Able’s Device Auto-login settings match the unit’s
username and password (by selecting N-Able > Settings from the N-Able
tool bar).

NOTE: N23X2 units force HTTPS connections, so your web browser may give
you a security warning. N-Able on Windows will ask you to download OpenSSL
for Windows to connect HTTPS. You can disable the Force HTTPS Connection
checkbox on the unit’s Security page if desired.

Basic KVM Setup

The N2312 Encoders and N2322 Decoders are KVM-capable. By default, USB
connections are enabled and configured to follow video switching. Follow
these steps for basic KVM setup.

1. On the N2312 Encoder, connect the USB Mini-B port to the computer
to be controlled.

2. Connect the computer’s video output to the Encoder’s HDMI IN port.

3. On the N2322 Decoder, connect the HDMI OUT to the display.

4. Connect a USB keyboard and mouse to the Decoder’s USB Standard-A
ports (they can be plugged into either port).

5. Using N-Able, click the Unit Management tab.

6. Click the Auto Discover button to discover your new devices (if you
have not already done so).

7. Once discovery is complete (and you see the new units listed in N-Able),
click the Video Matrix tab.

8. On the matrix, click the common cell for the desired Encoder/Decoder
streaming combination. See the screen shot below for an example.

9. Click the Ta ke button to make the change to your matrix. The radio
button turns green to indicate the connection was successful.

modifying the configuration. When you switch video streams
(using the matrix as shown above) the USB functionality will
follow the video.

Use N-Able’s USB Matrix tab to switch USB control (without
affecting video).

To switch video streams without affecting USB control, first
select N-Able > Settings from N-Able’s main menu. When the

N-Able Settings dialog box is displayed, disable the USB
