For RS485 communication the sender / receiver has to by switched in either send or receive mode. This is done normally by an additional output pin. The board I have doesn't do this and switches between send and receive depending on the state of TX. Dec 04, 2021 · All level converters I used (between RS232<=>RS485 then) were happy with an additional signal (usually the RTS pin) to switch the RS485 sender on and off. In my experience, this is a little time critical - turning the sender off too late may cause lost characters sent by the attached device, so this might be too slow in micropython.
