-
Termination Resistors:
- Use 120Ω termination resistors at each end of the RS-485 bus
- Ensure proper resistor placement for optimal signal integrity
-
Power Supply Decoupling:
- Place 0.1μF ceramic capacitors close to VCC pins
- Consider additional bulk capacitance for power stability
-
Isolation Barrier:
- Maintain appropriate creepage and clearance distances
- Follow safety standards for reinforced isolation applications
-
Grounding:
- Implement proper grounding techniques for isolated systems
- Avoid ground loops through the isolation barrier
