8-port RS-232 PCI Express serial board


Features and Benefits

Supports 128 high-performance serial ports per system
Dramatically decreases host CPU loading
Modular design makes port expansion easy
Monitor transmission status with LEDs on the module and two 7-segment displays
Drivers provided for a broad selection of operating systems
460.8 Kbps maximum baudrate


The intelligent C320Turbo serial boards are expandable and flexible COM/TTY solutions for RS-232 applications that require connecting up to 128 serial devices to one computer. The C320Turbo’s on-board CPU and large dual-port memory take the load off host systems whose performance and scalability are critical for large-scale systems.

Drivers provided for a broad selection of operating systems

In addition to providing COM port drivers for all major operating systems, Moxa also supports the following dedicated operating systems for customers’ special needs.

  • DOS
  • QNX 4.2x
  • Windows
  • Linux 2.4/2.6
  • Windows (x64)
  • Linux (x64)
  • SCO UnixWare 7
  • SCO OpenServer 5/6
  • SCO UNIX SVR 4.2

Dramatically decreases host computer’s CPU loading

The C320Turbo boards have a state-of-the-art onboard CPU thatdramatically reduces the host computer’s loading by up to 68%* forapplications that use 32 ports per board.
