AMX SVSI NMX-ATC-N4321 Quick Start Manual

Overview

The SVSI NMX-ATC-N4321 Audio Transceiver sends and receives audio over
IP. Balanced or unbalanced audio input coming into the N4321's AUDIO IN
port is converted into network packets for output through the RJ45 port.
Units can be stacked to deliver low-latency, multi-channel audio over a
house network or a physically separate network (using the two auto-sensing
gigabit Ethernet ports). One Ethernet port is Power Over Ethernet (PoE) for
use with a PoE switch, eliminating the need for an external power supply.
Since control is the same as SVSI's video matrix, video and audio matrices
can be combined and routed using the same controller.

Basic Installation Guidelines

Connections Options
Power: PoE: Connect the unit's P0 port to an active, PoE-enabled
network switch
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: PoE units: If using PoE to power the unit, you should already
have a network connection.
Externally powered units:
or P1 port to the network with the appropriate cable
Audio: For audio encoding, connect a line level analog audio source
to the Audio input terminal block plug connector

Establishing Connection

Before using your N4321 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. N-Series
devices are shipped in Auto-IP mode with a default IP address of
169.254.xxx.xxx. 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. See FIG. 2.

SETTING A STATIC IP ADDRESS

Status
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. Contact
your network administrator if you are unsure of how to configure the existing
interface. If the computer already 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
N-Able:
PC version -
Mac version -
2. Attach your N4321 unit(s) to the layer-3 network switch.
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.

Understanding the N-Able Interface

Once the host IP address is configured properly, you can view all discovered
units using N-Able. Access the N4321 units from the following tabs:
• Unit Management tab - N4321 units have N4000 Audio listed in their
Type field.
• Audio Matrix tab - N4321 units have a musical note icon next to their
names (as shown in FIG. 3).
FIG. 3 AUDIO MATRIX
In the Audio Matrix tab (shown previously in FIG. 3) Hover over a unit name
with your mouse to view tool tips providing critical information about each
device. Double-click any device to view its Settings page (shown in FIG. 4).
If prompted, enter admin and password for the default login username and
password.
