SN65HVD21DR Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the SN65HVD21DR?
  The maximum cable length supported by the SN65HVD21DR 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 configure the SN65HVD21DR for half-duplex or full-duplex operation?
  The SN65HVD21DR can be configured for half-duplex or full-duplex operation by connecting the corresponding pins. For half-duplex operation, connect the TX and RX pins together. For full-duplex operation, keep the TX and RX pins separate.
• What is the maximum data rate supported by the SN65HVD21DR?
  The SN65HVD21DR supports data rates up to 1 Mbps.
• Is the SN65HVD21DR compatible with other RS-485 transceivers?
  Yes, the SN65HVD21DR is compatible with other RS-485 transceivers that comply with the EIA/TIA-485 standard.
• How do I handle bus contention and fault tolerance in a multi-point RS-485 network using the SN65HVD21DR?
  To handle bus contention and fault tolerance in a multi-point RS-485 network, use a combination of hardware and software techniques such as bus termination, biasing, and error detection and correction mechanisms.
