ST485BN Frequently Asked Questions (FAQs)

  • The maximum cable length supported by ST485BN is 1200 meters, but it depends on the baud rate and cable quality.
  • To ensure signal integrity, use twisted pair cables, keep the transmitter and receiver close to each other, and use a common ground between the transmitter and receiver.
  • The maximum data rate supported by ST485BN is 10 Mbps, but it can be limited by the cable length and quality.
  • Yes, ST485BN can be used for half-duplex communication by using the DE (Driver Enable) pin to switch between transmit and receive modes.
  • To handle bus contention, use a non-return-to-zero (NRZ) encoding scheme and implement a collision detection mechanism to detect and resolve bus contention.
