RS232 Multi Computer Adapter

  • RS232 Multi Computer Adapter

Two data sources - one peripheral

The Multi Computer Adapter enables connection of two serial data sources with a peripheral. Automatic switching between both senders is time-controlled.



  • 3x RS232/422/485, 9-pin SUB-D connector

Management and connectivity:

  • 2 PCs share a serial terminal device:
    • Printer
    • Plotter
    • Hand scanner
    • Card reader
    • etc...
  • Switching modes:
    • Automatic switching on "first come, first served" basis
    • manual switching using buttons directly on the device
    • with simultaneous sending of all data on the Master port to both Slave ports with automatically switching feedback channel (splitter mode)
  • Data back channel allows connection of bi-directional peripheral devices
  • Individual configuration of interfaces
  • Conversion of baud rate, data format and handshake protocol possible
  • Integrated diagnostic and startup aid: Setting dump

Power supply:

  • External power
    • Wide voltage range up to 24V

Standards & more

  • Conforms to standards both in office and industrial environments:
    • High noise resistance per EN 61000-6-2
    • Low noise emission per EN 55032:2015 + A1 Cl. B, EN 61000-3-2 & EN 61000-3-3
  • 5 year guarantee
