SN65HVD11QD datasheet by Texas Instruments

SN65HVD11QD Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the SN65HVD11QD?
  The maximum cable length supported by the SN65HVD11QD 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.
• How do I ensure reliable communication over long distances using the SN65HVD11QD?
  To ensure reliable communication over long distances, it is recommended to use a shielded twisted-pair cable, keep the transmitter and receiver grounds connected, and use a common mode choke to reduce electromagnetic interference (EMI).
• What is the maximum data rate supported by the SN65HVD11QD?
  The SN65HVD11QD supports data rates up to 1 Mbps.
• Can the SN65HVD11QD be used in a multi-point configuration?
  Yes, the SN65HVD11QD can be used in a multi-point configuration, but it is limited to a maximum of 32 devices on the same bus.
• How do I handle bus contention in a multi-point configuration using the SN65HVD11QD?
  To handle bus contention in a multi-point configuration, it is recommended to use a non-return-to-zero (NRZ) encoding scheme and implement a collision detection and retransmission mechanism in the application software.
