About Livewire+
This manual covers the details of the SDI xNode. To learn more about Livewire+ and AoIP, you may wish to read
Introduction to Livewire+: System Design Reference and Primer which is available on the Telos Alliance website
(www.telosalliance.com) and Audio Over IP: Building Pro AoIP Systems with Livewire+ by Steve Church and Skip
Pizzi, available from Elsevier Press.
In these publications we explain the ideas that motivated Livewire+ and how you can use and benefit from it, as
well as nitty-gritty details about wiring, connectors, and the like. Since Livewire+ is built on standard networks,
we also help you to understand general network engineering so that you have the full background for Livewire+’s
fundamentals.

SDI Output
Two SD/HD-SDI output connections are included on the rear of the SDI xNode. All 16 audio channels in the SDI
stream are available for embedding and pair shuffling.
Installation and Mounting
Installation
The xNode is a fanless device, so it may be located in a control room or other location where fan noise cannot
be tolerated. Because this unit is passively cooled, it is recommended to leave an empty space above the unit
when mounted in a rack or other enclosure. An internal thermal sensor is designed in to the product, so that the
operating temperature of the xNode may be monitored remotely
Mounting
The SDI xNode includes a rack mounting kit. The mounting hole location and pattern is consistent with all
xNodes, so any xNode may be mounted using the available kit, and two of them may be mounted side by side.

8| Section 2
Rack Mount kit
The rack mount kit provides the ability to secure the xNode into an equipment rack. The kit contains two short
rack ears, one long rack ear, and a spacer plate.

Single xNode
To rack mount a single xNode, secure the short rack ear to one side of the xNode and secure the long ear to the
opposing side of the xNode.
Figure 7 - xNode with long and short rack ear installed

9| Section 2
Two xNodes
It is possible to install two xNodes in a side-by-side configuration. The mounting hole locations and pattern are
consistent with all xNodes, so any xNode may be mounted next to the SDI xNode.
To mount two units side by side:
Remove the top lid from both xNodes. Place two xNodes side by side. Place the spacer plate between the two xNodes
Figure 8 - Spacer plate in between two xNodes, top view
