Hi, I'm setting up the following MultiDrop topology along 2.4km of rail line. There are 24 devices on the bus. I have available 2 pair shielded cable along the length: 1 for power, 1 for RS485 (I think..maybe i should be thinking 10baseT and PoE.). I want to be able to connect to the serial port of any of the devices, only one at a time (PI Zero 2W) but I'd like to also be able to receive events when a device detects something. Any ideas for multiplexing serial over 485?
