RS485 Daisy-Chain Signal Fix -- 2

Job ID: 39827615

Budget: $25 – $50 USD

I have a daisy-chained PCB that links several boards over RS485. Each board carries a Microcontroller and the necessary communication modules. Everything powers up correctly, but the chain suffer a specific problem.

I need a fresh set of expert eyes to pinpoint why the misbehaving happens. This should happen in a remote session.
