RDM Tool

Patch and test DMX fixtures over Art-Net, from an Android phone.

RDM Tool speaks Art-Net and RDM (ANSI E1.20) to a node on your network and to the fixtures on the DMX line behind it. It is for the moment on site when the laptop is in the truck: change a start address, rename a fixture, flash it so you know which one you are holding, or drive a few channels to see whether it lights.

What it does

• Discovery — finds the Art-Net nodes on the network and the RDM fixtures behind them, and says in plain words why a scan found nothing.
• Patching — DMX start address, fixture name and DMX personality. Every change is read back, and one that cannot be confirmed is reported as unconfirmed rather than as done.
• Identify — make a fixture flash.
• DMX test — a slider per channel, for a discovered fixture or for any universe and start address you pick.
• Parameter inspection — everything a fixture reports, its sensors and sub-devices, and any parameter as a raw hex block.
• Help and pinouts — 5-pin and 3-pin XLR and RJ45, both faces drawn. Works without a network, which is the point of having it in the app.

What you need

An Art-Net node with RDM enabled and an Android phone on the same network as it. Art-Net conventionally uses the 2.x.x.x range, so the phone needs an address in that subnet. Such a network has no internet, and Android will offer to leave it — choose to stay connected, or nothing will be found. The node does the talking on the DMX wire; the phone never touches DMX directly. It was tested to work with several ESP32 mini node implementations (ESP32 WLAN DMX/RDM Node from DMXFREAK or LuxDMX).
