Features and Benefits 

  • Cost-effective ISA boards with 4 RS-422/485 ports
  • RS-485 data direction control with ADDC® or by RTS
  • 921.6 kbps maximum baudrate for super fast data transmission
  • 16-byte FIFO and on-chip hardware flow control
  • Surge protection and electrical isolation available
  • Built-in termination resistors

Overview

The CI-134 series ISA boards come with 4 independent RS-422/485 serial ports for connecting data acquisition equipment and other serial devices to a PC. Connect your devices over longer distances—up to 1.2 km (4000 ft)—and ensure greater reliability in industrial environments with on-board surge protection and electrical isolation (available with some models). Enjoy greater versatility by using point-to-point full duplex connections, or set up a half duplex RS-485 multi-drop network.
