Free open-source Windows/Linux DMX/RDM controller and sniffer for ETC's Gadget-family USB hardware, able to capture DMX/RDM data, control DMX levels, and act as an RDM controller.
Protocols it speaks
| Protocol | Direction | Notes |
|---|---|---|

| rdm | bidirectional | Acts as an RDM controller and can capture RDM traffic; full feature set requires ETC Gadget II hardware. |
What to watch for
Explicitly labeled 'UNOFFICIAL' in the repo — a community project, not an ETC-supported product.
Requires specific ETC USB hardware (USB Whip, Gadget I, or Gadget II); feature availability (e.g. RDM controller mode) varies by which device and firmware version you have.
Typical use
- Sniff raw DMX/RDM traffic on a line using an ETC USB Whip or Gadget interface
- Run RDM discovery and send GET/SET commands to responders for fixture diagnostics
- Bench-test a fixture's DMX response by manually setting channel levels
