A node for outputting DMX through a USB dongle
This node looks for a UDMX dongle with USB ID 0403:6001 and allows a single DMX channel to be set to a value.
It works with the Chinese usb to DMX adapters readily available (e.g. search ebay for "usb dmx").
Use the 'Manage Palette' option from the Node-Red admin panel, then search from the 'Install' tab.
If not found, you can install manually:
In your .node-red folder run:
npm i node-red-contrib-udmx
then restart the node-red service.
Set msg.topic to the DMX channel (1-512) and msg.payload to the value (0-255).
- Restart node-red after inserting dongle to ensure it is detected
-
The dependency node-usb requires a library installing first on linux OS (inc. Raspberry Pi). Full details under Installation here: https://github.com/tessel/node-usb#readme. Be sure to do this before trying to install UDMX.

Some distributions do not include pkg-config, which is required by a dependancy. Run
sudo apt install pkg-config
if installation fails and then try again.
