Question 1

How do I set up node-dmx with an Art-Net controller?

Accepted Answer

Use the 'artnet' driver when adding a universe with dmx.addUniverse(), specify the target IP address as the device_id, and ensure your network supports Art-Net. The README provides driver-specific options for configuration.

Question 2

node-dmx vs dmx4js for Node.js DMX control?

Accepted Answer

node-dmx offers broader hardware driver support and a built-in animation engine, making it better for complex sequences. dmx4js is simpler and lighter but has fewer features and may not support as many interfaces out-of-the-box.

Question 3

How to create a fading light effect with node-dmx?

Accepted Answer

Use the DMX.Animation class: create an instance, add steps with channel values and durations using add(), and apply easing functions like 'inOutQuad' for smooth transitions. Example code in the README shows how to run animations with loops.

Question 4

Can node-dmx run on a Raspberry Pi for outdoor lighting?

Accepted Answer

Yes, via supported drivers like Art-Net or with compatible USB DMX interfaces such as Enttec USB DMX Pro. However, test performance as Node.js isn't real-time, and ensure the hardware driver is available for your setup.

Question 5

How to add a custom moving head fixture to node-dmx?

Accepted Answer

Manually define the channel mapping in your code or contribute to the devices.js file via pull request. The library doesn't auto-detect devices, so you must reference the fixture's manual to specify each channel's purpose.

Question 6

What's the best hardware for reliable DMX output with node-dmx?

Accepted Answer

Enttec USB DMX Pro or DMXKing Ultra DMX Pro are recommended due to stable drivers. Avoid Enttec Open DMX USB, as the README warns it's unstable. Always check driver compatibility in the documentation.
