So I wan to control a bunch of devices. I though first of using RS485 but after some digging I figured out this might not work as I don't really have a pure daisy chain. The configuration I would like to use is 'star-daisy-chain':
Each 'Box' has an input and output for a main line and 4 small outputs. The length of the cables between boxes is around 10 meters and the length of the cables going out of the boxes is 2 meters at most. Both synchronous and asynchronous connections can work here. The bandwidth can be as low as 19200.
I would like to have 5 'Boxes' and 20 devices (at most)
What would be the best and simplest way to deal with this? It isn't so simple to daisy chain everything even though possible.
