① Install Relay

The relay is a small local script that bridges your Daktronics console and Tria to this page.

↓ Download Relay — unzip, then double-click START_RELAY.bat. It installs Python dependencies automatically on first run.

For autostart on Windows login, run SETUP_AUTOSTART.bat once.

② Configure

Ultrix IP & Port — your Ultrix router's IP and RossTalk port (default 7788). UMDs must be set to Remote mode.

UDP Port — The Daktronics AllSport 5000 broadcasts scoreboard data over UDP. Enter the port number configured on the AllSport console for the active sport.

Sport — select from the left panel. Fields populate automatically.

③ Assign UMDs

For each field you want to route: enter a UMD number, optional prepend/append text, choose text and background colors, and toggle On.

The Live column shows incoming data in real time so you can verify values before enabling routing.

Click T in the preview panel to fire a test to any UMD.

④ Break Clock

The Break Clock tab generates a ready-to-run espn_breakclock_tray.py configured with your settings.

It requires Chrome + Selenium. Install once: py -m pip install selenium pystray pillow webdriver-manager

Run it and a Chrome window opens — log in to the ESPN break page. The script handles the rest from the system tray.

⑤ Save & Load

Use ⬇ Settings in the toolbar to download your full configuration as a JSON file.

Use ⬆ Load to restore a saved config — all field assignments, colors, and UMD numbers reload instantly.

The relay also auto-saves config locally between sessions.

UMD colors update automatically based on clock urgency (green → amber → red as time runs out).

The UMD Mixer Launcher is a single script that starts everything at once — the relay, the UMD Mixer browser UI, and the ESPN break clock Selenium window — all from one double-click. A system tray icon controls everything. Configure your settings below and download a pre-configured launcher.
