The ADK-3485 is a serial communication interface module providing one RS232 interface, two RS485 interfaces and two RS422 interfaces.

Overview

  • RS232: 1x standard DB9 male serial interface, MAX3232 RS232 / TTL level conversion, data rate up to 120Kbps
  • RS485: 2x interfaces on 3-wire terminal blocks, MAX3485 RS485 / TTL level conversion, data rate up to 500Kbps
  • RS422: 2x interfaces on 5-wire terminal blocks, MAX3490 RS422 / TTL level conversion, data rate up to 500Kbps
  • Termination: 120 ohm matching resistor, enabled by fitting the jumper cap; shorting is recommended for long-distance transmission
  • Bus: multi-machine communication supported, up to 128 devices on one bus
  • Design: industrial-grade design, strong anti-interference capability, effective lightning protection
