Design Notes
Place the ADM3065EBRMZ close to the bus connector to minimize trace length and reduce EMI. Use 120 Ω termination resistors at both ends of the RS-485 bus to prevent signal reflections. Keep the A and B traces parallel and close together to maintain differential impedance.
Decouple the VCC pin with a 0.1 µF ceramic capacitor placed as close as possible to the pin. For noisy industrial environments, add a 10 µF bulk capacitor. Ensure the power supply can handle the transient currents during data transmission.
Avoid bus contention by ensuring only one driver is enabled at a time. Use the RE and DE pins to control the bus direction. When the bus is idle, bias the A and B lines to a known state using pull-up and pull-down resistors to prevent undefined receiver output.
