SN65HVD22DR Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the SN65HVD22DR?
  The maximum cable length supported by the SN65HVD22DR 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 SN65HVD22DR for half-duplex or full-duplex operation?
  The SN65HVD22DR can be configured for half-duplex or full-duplex operation by connecting the RTS (Request to Send) pin to the CTS (Clear to Send) pin for half-duplex operation, or by connecting the RTS pin to a microcontroller or other device for full-duplex operation.
• What is the maximum data rate supported by the SN65HVD22DR?
  The SN65HVD22DR supports data rates up to 1 Mbps.
• Is the SN65HVD22DR compatible with other RS-485 transceivers?
  Yes, the SN65HVD22DR is compatible with other RS-485 transceivers that comply with the EIA/TIA-485 standard.
• How do I protect the SN65HVD22DR from ESD and other transient events?
  The SN65HVD22DR has built-in ESD protection, but additional protection measures such as TVS diodes or surge protectors can be used to further protect the device from transient events.
