4-port RS-232/422/485 Universal PCI serial boards with optional 2 kV isolation



  • 4-port high speed communication board (2 ports for RS-422/485, 2 ports for either RS-232 or RS-422/485)
  • RS-485 ADDC™ data control or by RTS
  • Various connection options
  • Data transmission speed up to 921.6 Kbps
  • On-chip hardware flow control
  • Surge Protection and Optical Isolation available as options
  • Built-in termination resistors



The CP-114 Series of multiport serial boards is designed for RS-232 and RS-422/485 industrial communication. The CP-114 Series has 2 ports for RS-232 or RS-422/485, selectable by jumper, and 2 ports for RS-422/485, with each RS-422/485 port able to control up to 32 devices in a multidrop environment.


By using ADDC™ (Automatic Data Direction Control) intelligence, applications can easily manage the half-duplex RS-485 port’s data transmitting and receiving without the need for writing extra code. In addition, on-chip hardware flow control and built-in termination resistors guarantee data integrity, and optical isolation and surge protection options are also available to deliver high reliability. All of the above attributes make the CP-114 Series of multiport serial boards suitable for harsh industrial applications.



  • Three serial interfaces in one board provides greater connection flexibility
  • High reliability in harsh industrial environments
  • ADDC™ intelligence simplifies RS-485 software programming, reducing development time and cost



  • Multipoint data acquisition
  • Industrial control
  • Factory automation
  • Embedded industrial machines
  • Remote serial device control
  • SCADA systems
