SN65HVD485EDGKR Frequently Asked Questions (FAQs)

  • The maximum cable length supported by the SN65HVD485EDGKR is dependent on the baud rate and the type of cable used. As a general guideline, the maximum cable length for a 9600-baud rate is around 4000 feet (1219 meters), while for a 115200-baud rate, it is around 100 feet (30 meters).
  • To ensure EMC with the SN65HVD485EDGKR, it is recommended to follow proper PCB layout and design guidelines, use a common-mode choke or ferrite bead on the RS-485 bus, and ensure proper grounding and shielding of the device and cables.
  • The SN65HVD485EDGKR supports up to 32 nodes on a single RS-485 bus, assuming a 120-ohm termination resistor at each end of the bus.
  • To handle bus contention and data corruption, it is recommended to implement a collision detection mechanism, use a protocol with error-checking and correction, and consider using a transceiver with built-in fault-tolerant features.
  • The recommended operating temperature range for the SN65HVD485EDGKR is -40°C to 85°C. However, the device can operate up to 105°C with reduced performance and reliability.
