I'm currently working on a project involving the MAX485 module, DMX512 communication, and the DmxSerial.h library on Arduino. I've successfully transmitted DMX512 data using the MAX485 module and the DmxSimple.h library, and everything works as expected. I've attached pictures (Picture Number 1) to illustrate the successful transmission setup.
However, I'm encountering difficulties when trying to receive DMX512 data from a lighting board. It's important to note that receiving DMX requires different wiring than transmitting. I've wired the system differently for the reception part (see Picture Number 2), but unfortunately, I can't get the microcontroller to read the signal. Here are some specifics about my setup:
-
Arduino model: Arduino MEGA 2560
-
MAX485 module:

-
Wiring setup for transmission (Picture Number 1):

-
Wiring setup for reception (Picture Number 2):

I am using the DmxSerial.h library for receiving DMX, and I've tried the standard example "DmxSerialRecv" from the library's GitHub repository.
If you have any thoughts on what might be causing the problem or tips on how to resolve it, I would love to hear them!
Thank you for your help!
