DMX A/B vs DMX-+

[Olifiers]

Hey folks!

On the schematic available on the github docs, the MAX485 outputs DMX A and DMX B, yet every DMX pinout I can find refers to DMX - and DMX + (pins 2 & 3, with pin 1 being GND).

What's the equivalence between A/B and -/+?

Thanks for the help!!!

DMX A equals DMX+ (positive signal), Pin 3
DMX B equals DMX- (inverted signal), Pin 2
