Livewire Simple Delegation Switcher

Free Software for Radio Broadcasters

Livewire Simple Delegation Switcher (lwSDS) is a freeware Livewire Source Selector. You can select any Livewire Source on your network, and send it to any xNode, Classic Node, QoR, PowerStation, IP-Driver, or Omnia Processor.

Originally released in July 2017, lwSDS has had over 160 downloads and is in use by radio and TV stations all over the world!

What does lwSDS do?

Livewire Simple Delegation Switcher acts as a single button-selector window. You can think of it like a simple Pathfinder Mini panel, or the press buttons on the front of your old analog audio switcher.

The software consists of a single configuration file and EXE. You can setup as many selector buttons as you like. Each one represents a Livewire Stream Number. As soon as you click on a button, it sends that Livewire stream to the configured destination. The active source has a red coloured background.

Your sources could be studios, computers, codecs, satellite feeds – anything! As long as it exists on your network as an Axia Livewire source, you can use it.

The application uses the Livewire Routing Protocol – a TCP based protocol with simple text commands. It does not require access to the Multicast data on your Axia Livewire network, so you can use it from any separate network – so long as TCP port 93 is accessible.

This software does not require a central server, yet you can still run it on as many computers as you like at any one time. The software subscribes to route change notifications on the Livewire device, so as soon as you change the stream number in one place, it shows up on every other computer running this software.

Who’s using lwSDS?

There have been over 160 downloads (as of December 2017). Of these people, there’s a few who’ve contacted us to let us know. These include:

Kirk Harnack’s IP-STL – Kirk is running 4 radio stations over an IP-STL, and uses lwSDS to control paths and backup feeds. Watch the video for info on his setup:

A UK TV/Radio News Network is using it as a source selector for their news operations. They have a lot of columns! This was one of the first installations of lwSDS – and lead me to implement support for multiple columns.

A number of Community and Narrowcast radio stations in Australia are using it, including 2UUU Shoalhaven, Pulse 94.1 Wollongong, and Pulse FM Tasmania.

TAFE NSW has it in their radio training studios in Ultimo, for studio delegation and headphone switching.

Tim Wright (from WLS, Chicago – a Cumulus News/Talk station) is using lwSDS – and has even modified it to run on a Raspberry Pi!

A few people in The Broadcasting Club on Facebook have shared how they use it. This includes Ben Slagle of the Cumulus cluster in Youngstown, Ohio who’s using it to control the speaker feed in their lobby. He’s also put it on their laptop for remote broadcasts, allowing presenters to control the return audio – genius!

  • Axia Nodes (the original ones)
  • Axia QoR (Radius & iQ)
  • Omnia One
  • Axia IP Driver for Windows
  • BreakawayOne Livewire/AES67 add-on (you need to explicitly allow it in the Livewire config)

Troubleshooting

There are a few common problems you may experience while running this program. Here’s some suggested troubleshooting steps:

  1. The Livewire Device isn’t accessible
    1. Try pinging the Livewire device
    2. Ensure there is no firewall blocking access on TCP Port 93
    3. Check to see there is no password set on the device (this isn’t currently supported)
  2. There is an error with my JSON file
    1. Compare the configuration to the sample provided
    2. Copy and paste your full configuration on JSONLint to check it for errors
  3. The application crashes with the error message “Failed to execute script LW-Delegation-Swicther
    1. Try running the Debug version of the program from Command Prompt
    2. Log an issue on GitHub with the full error message and any other information that would help us debug it
