AMX NMX-ATC-N4321D Audio Transceiver User Guide

Overview

The SVSI NMX-ATC-N4321D Audio Transcoder with Dante is an audio-over-IP solution that sends and receives multichannel balanced or unbalanced audio over IP. The NMXATC-N4321D can receive an analog audio input and convert that into network packets, allowing the user to switch and route the audio, just like data and voice.The balanced analog audio output receives an audio-over-IP stream and decodes to analog while preserving audio fidelity. The NMX-ATC- N4321D provides audio matrix switching and distribution using the same control options as SVSI’s Networked AV video switching and distribution solution. One Ethernet port is PoE for use with a PoE switch,eliminating the need for an external power supply

Attaching Signal and Control Cables

The following table explains how to attach cables to the Audio Transceiver.

IMPORTANT: Audio Transceiver must be securely mounted and connected to the switch before attaching the remaining cables.

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

Establishing Connection

N4321D Audio Transcoder 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 N4321D Audio unit, it must be configured using the free N-Able device management software. However, you cannot configure units until they are in the same subnet as the host computer. The sample steps below show how the requiredchanges (to the host computer’s IP settings) are made in a Windows environment.

Steps for IP address configuration:

From the Control Panel > Network and Internet dialog box, select Network and Sharing Center.
Select Change adapter settings.
Select the wired interface connected to your AV network.
Click the Properties button.
Scroll down the list to the Internet Protocol Version 4 (TCP/IPv4) option. Highlight it and click the Properties button.
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, enter a unique 169.254.xxx.xxx IP address with a 255.255.0.0 Subnet mask. 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. Please contact your network administrator if unsure how to configure the existing interface.

Steps for Dante’s IP address configuration:

Use the host computer to download and install the latest version of Dante Controller:
PC Version –https://my.audinate.com/support/downloads/dante-controller
Attach your N4321D Audio unit(s) to the managed network switch.
Connect the host computer to the same managed network switch.
Open the Dante Controller application.
Refer to the Dante Software and directions to configure the IP address

Steps for auto-discovering devices on the network:

Use the host computer to download and install the latest version of N-Able: PC Version – http://www.amx.com/products/N-ABLE-C.asp
Attach your N4321D Audio unit(s) to the managed network switch.
Connect the host computer to the same managed network switch.
Open the N-Able application.

Note: 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.

Logging in Using N-Able Software

Once the host IP address is configured correctly, you can view all discovered units using the N-Able software. Access the N4321D Audio units from the following tabs:

Unit Management tab – N4000 Audio is listed in the Type field.
Audio Matrix tab – N4321D Audio units are found on the SVSI Audio subtab of this screen.

You can access any of the main pages of the unit’s GUI from this page. Doubleclick the unit’s name (in one of the above lists) to view its Settings page. If prompted, enter admin and password for the default username and password.

Once logged in, you can change the username and password (using the options on the unit’s Settings page).

NOTE: 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 toolbar).

NOTE: N4321D Audio units can be configured to force HTTPS connections, so your web browser may give you a security warning.
