SN65HVD485EDR Frequently Asked Questions (FAQs)

  • The maximum cable length supported by the SN65HVD485EDR is dependent on the baud rate and the type of cable used. As a general guideline, the maximum cable length is around 100 meters at 9600 bps and 10 meters at 1 Mbps.
  • To ensure EMC with the SN65HVD485EDR, follow proper PCB layout and design guidelines, use a common-mode choke or ferrite bead on the bus lines, and ensure proper shielding and grounding of the device and cables.
  • The recommended termination resistor value for the SN65HVD485EDR is 120 ohms, but this value may need to be adjusted based on the specific application and cable characteristics.
  • Yes, the SN65HVD485EDR can be used in a multi-drop configuration, but each device must have a unique address and the total bus length must not exceed the maximum recommended length.
  • To handle bus contention and collisions with the SN65HVD485EDR, implement a non-return-to-zero (NRZ) encoding scheme, use a collision detection mechanism, and implement a retry mechanism to resolve collisions.
