GPIO and Control
Livewire GPIO for visual radio automation
Your Livewire system carries the logic of the studio, like a mic switched on or a button pressed. VRA reads those GPIO states and turns them into camera, graphics and macro actions, and you can switch a GPO from VRA by hand when you need to.
What VRA does with Livewire Routing Protocol.
Ports found for you
VRA reads the endpoint's GPI and GPO ports, so you pick from a list instead of typing paths.
A GPI change runs a command
Use a mapped GPI as the condition of an automation. When it changes, the automation sends the same command a dashboard button or microphone trigger would.
Outputs by hand
Switch a mapped GPO on, off or give it a short pulse from the GPIO page, with the live state of every port next to it.
Inverted logic, without rewiring
Where a port reads the wrong way round, invert it in VRA.
How to set it up.
Requirements
- A Livewire endpoint that answers LWRP, reachable from VRA Core.
- TCP access to port
93, or the port configured on the endpoint. - The LWRP password when authentication is enabled.
- GPIO in your VRA licence.
In VRA, open Settings, Studio, GPIO and add a Livewire LWRP connection.
Enter the Livewire endpoint host and port. The default LWRP port is
93.Add the password when the endpoint requires one, then save and connect.
Pick the GPI and GPO ports you need from the discovered list and map them. Invert a port where the active state is reversed.
Operate the source GPIO and check its state on the GPIO page before attaching it to an on-air action.
Livewire Routing Protocol questions
Does VRA work with Livewire GPIO? +
Yes, over LWRP. VRA Core connects to your Livewire endpoint, on port 93 by default, reads its GPI and GPO ports and uses GPI changes as conditions for automations.
Can VRA send a Livewire GPO? +
By hand, yes: a mapped GPO can be switched on, off or pulsed from the GPIO page in VRA. Automations and macros do not drive GPO ports.
Does every LWRP connection need a password? +
No. Enter one only when authentication is enabled on the endpoint.
Does LWRP carry microphone audio to VRA? +
No. LWRP is control only. Audio Triggers reads the microphones from an audio interface or driver on the VRA machine.

About Livewire Routing Protocol.
LWRP, the Livewire Routing Protocol, is the TCP control channel Livewire devices answer on. VRA Core connects to an endpoint, reads how many GPI and GPO ports it has and keeps the state of every mapped port up to date.
A GPI that changes can be the condition of an automation, which then runs its command: take a camera angle, cut the switcher, fire a macro. Mapped GPO ports can be set on, off or pulsed from the GPIO page in VRA. Automations and macros do not drive a GPO. LWRP carries control only, so the microphone audio for Audio Triggers still comes in through an audio interface or driver.
What you can do with this connection
Automated camera switching for radio
Switch cameras from microphone activity and prepare PTZ shots off air.

More integrations.
Ember+
Use Ember+ parameters as GPIO triggers for visual radio. VRA reads the console and router values you map to cut cameras, change graphics or run macros.
Livewire+ AES67
Livewire+ studios can switch cameras from their AES67 mics once a RAVENNA, Merging or Digigram driver receives them. VRA builds a trigger per mic.
Bitfocus Companion
Get Stream Deck control of your visual radio studio. The VRA Core module for Companion puts on air, cuts, macros and auto switching on keys with tally.
