➕ Add to SignalRGB

Or paste this URL into your browser:

signalrgb://addon/install?url=https://github.com/capkz/V2X-SignalRGB

2. Install the bridge service (once)

The plugin needs a small background service to talk to the device. V2XBridge.exe is included in the addon — no .NET install needed.

Option A — from the plugin panel: open the Katana V2X device panel in SignalRGB, click Open addon folder, then right-click V2XBridge.exe → Run as administrator.

Option B — from PowerShell (admin):

& "$env:LOCALAPPDATA\WhirlwindFX\SignalRgb\cache\addons\V2X-SignalRGB\V2XBridge.exe" --install

The service starts immediately and auto-starts on every boot.

To uninstall the service:

& "$env:LOCALAPPDATA\WhirlwindFX\SignalRgb\cache\addons\V2X-SignalRGB\V2XBridge.exe" --uninstall

3. Restart SignalRGB

The Katana V2X device will appear in the Devices tab.
