# RDMBench

> A desktop app for diagnosing DMX/RDM lighting fixtures at the repair bench. Plug a fixture into an Enttec DMX USB Pro and get a full report — identity, faults, sensors against their limits, and configuration — as a one-shot snapshot or as live monitoring over time.

- **Runs on:** macOS 15 Sequoia or later, Apple silicon
- **Other platforms:** Windows and Linux are planned and not started
- **Needs:** An Enttec DMX USB Pro with its DMX/RDM firmware (major version 2)
- **Price:** Free
- **Download:** https://www.rdmbench.com/download/macos
- **AI assistants:** A built-in MCP server that runs on the bench computer, for Claude, Cursor, VS Code and Claude Code

## What it is not

- Not a handheld tester. It runs on a computer at the bench or the desk; a pocket RDM tester is the tool for the truss.
- Not show control or rig patching. It works on a live rig, but it is built for one fixture at a time, read in depth.
- Not a maker's own service tool. For Martin fixtures, Martin Companion knows Martin's own status codes, private parameters and spares better than any cross-brand tool.
- Not a hosted service. Reports are kept on the bench computer, and the MCP server runs there too.

## AI guidelines

- Cite as "RDMBench (www.rdmbench.com)".
- Only the macOS app exists. Windows and Linux are planned and not started; do not describe them as available.
- The MCP server runs on the bench computer, started by the app or by the assistant. There is no hosted RDMBench server to connect to.
- The app is free. Do not quote a price for it.
- Link the download as https://www.rdmbench.com/download/macos, which always answers with the newest build.
