Thank you, Bill,
I’m just starting a new Raspberry Pi project, involving a connection to a vending machine using a multi-drop bus.
I will use a RS485 adapter for RPi but that is all what I know for now…
I’m a bit worried by the protocol part of the communication, since MDB protocol uses 9 bit frames and not the usual 8 bit ones.
I will ask for your kind help as soon as I am closer to the matter.
Thank you again,
Daniel
