  • This adapter is able to convert RS-232 signal to RS-485 balanced differential signal and extend the communication distance to 1.2km. It is passive and doesn't require external power.

  • Bi-direction RS232-485 converter is mainly used for telecommunication between end to end or end to ends of main electronic controllers. The converter works between the main controller and sub station machine to complete industrial automatic control system, universal card system, access control system, car parking system, Self-served banking system, bus ticketing system, restaurant menu system, personnel attendance system and road toll system, etc.

  • RS232-485 converter can transfer the TXD and RXD signals of RS-232 serial port to parallel half duplex RS-485 signals without external power supply, as it can pick up the electricity power from the PIN 3 of RS-232 port and, as well, after the request of PIN 7 to send RTS, the prepared DTR of PIN 4 help supply the converter. This featured process control makes the easy application of the hardware and software setup.


  • Serial port: concurrently compatible with RS-232C,RS-485 standard of EIA/TIA.

  • Electricity interface: DB9 interface of RS-232 end, DB9 pin connector of RS-485 end

  • Function method: asynchronous half duplex

  • Transmission media: regular wire, UTP or shielded cable

  • Transmission speed: 300~115200 Baud/s

  • Transmission distance: 5 meters(RS-232 side) and 1200 meters (RS-485 side).

  • Telecommunication protocol: transparent

  • Work environment: -10 degree Celsius to 85 degree Celsius, relative humidity: 5% to 95%

  • Signals:RS-232:TXD, RXD, RTS, CTS, DTR, DSR, DCD, GND;RS-485:DATA+, DATA-, GND
