I’m tried to planning wiring RS485 device network in my house. I have done data cables distribution, but It is like star typologies, but I need to use RS485. I attached schematic wiring. I don’t know how to connect among devices. I suppose that, it not possible to get 5V than I use 12V and on I convert to 5V by the help LM7805. I use device 3rd product like digital 3 phase electrometer location in main power switch board. Every cables has twisted pair and shielding.
