ST485EBDR datasheet by STMicroelectronics

ST485EBDR Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by ST485EBDR?
  The maximum cable length supported by ST485EBDR is 1200 meters, but it depends on the baud rate and cable characteristics.
• How do I ensure electromagnetic compatibility (EMC) with ST485EBDR?
  To ensure EMC, use a shielded cable, keep the transmitter and receiver close to each other, and use a common mode choke or ferrite bead to reduce electromagnetic radiation.
• What is the maximum data rate supported by ST485EBDR?
  The maximum data rate supported by ST485EBDR is 10 Mbps, but it can be limited by the cable length and quality.
• How do I handle bus contention and collisions in ST485EBDR?
  Use a non-return-to-zero (NRZ) encoding scheme and implement a collision detection and retransmission mechanism in your application to handle bus contention and collisions.
• What is the power consumption of ST485EBDR?
  The power consumption of ST485EBDR is typically 15 mA in transmit mode and 1 mA in receive mode, but it can vary depending on the operating frequency and voltage supply.
