ST485ERBDR Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the ST485ERBDR?
  The maximum cable length supported by the ST485ERBDR is 1200 meters (4000 feet) at a data rate of 10 Mbps.
• How do I ensure reliable data transmission over long distances using the ST485ERBDR?
  To ensure reliable data transmission over long distances, use a shielded twisted pair cable, keep the cable away from noise sources, and use a common mode choke to reduce electromagnetic interference (EMI).
• What is the maximum data rate supported by the ST485ERBDR?
  The ST485ERBDR supports data rates up to 10 Mbps.
• How do I configure the ST485ERBDR for half-duplex or full-duplex operation?
  The ST485ERBDR can be configured for half-duplex or full-duplex operation by connecting the DE (Driver Enable) pin to VCC for half-duplex or to the RTS (Request to Send) signal for full-duplex operation.
• What is the power consumption of the ST485ERBDR?
  The power consumption of the ST485ERBDR is typically 30 mA at 5 V supply voltage.
