Hello there i am trying to make a DMX controller which has to be in rs485 connection because of the long distance that i need to send data .. and then the arduino slave is connected to the relay for now i am suing 8 channels.
The relay has to anknowlage the vixen comand so for each part i comand in Vixen one relay must go ative and procede to execute the order.
thanks
Heres my code
