node red was targeting an empty file for serialport…
ok a bit late but… could this work with a meanwell hlg-240H-24B?
That looks to be a 24VDC power supply. You will need a 12VDC version to power a ProXR controller.
the meanwell driver is for led lights, the pro50-21 would be the dimmer for that driver. is it capable of handling this?
The digital potentiometers are rated for 0-5VDC at 1mA current or less.
