Hello group –
I have the new DMX512 MODULE and the pins are labeled: SIG, NC, VCC, GND
On the website instructions it says that it should have 3 pins: SIG, positive signal, negative signal, which I think it’s actually talking about how the board connects to IC itself and doesn’t talk about how it’s supposed to be wired in.
VC on vellman modules usually means “not connected” so I looked at the data sheet and it doesn’t actually show any information about the pins for hookup. I know the MAX485 chip itself requires a twisted pair, but I wonder if this module is doing that itself? Anyone actually got this thing working?
