Overview / Features

This product is an isolated PCI bus-supported board designed for extending RS-232C compatible serial communication functionality on your PC. The product has two RS-232C communication ports. Higher noise-resistant models with isolation between a PC and bus line as well as a surge protection circuit for communication ports. With a 128byte built-in FIFO buffer for transmission and reception of each channel, the product supports a baud rate of up to 921,600bps. Windows / Linux compatible driver software is available that can be used just like a COM port on a PC. This product supports CONTEC-defined driver library “API-PAC(W32)” that provide local routines.

• Max. 921,600bps RS-232C Serial Communication

  • The product has two RS-232C-standard serial ports. Baud rates from 2 to 921,600bps can be set. When using the supported “Standard COM Driver Software” and “Driver library API-PAC(W32)”, baud rates from 15 to 921,600bps can be set.
• Isolation between channels and between PCs, surge protection for all signal lines

  • Comes with a driver software that allows the products to be used under Windows / Linux in the same way as COM ports on the PC. Under Windows, the product supports the OS-standard Win32 API communication function as well as Visual Basic MSComm. Under Linux, OS-standard tty driver’s standard-function can be used. In addition, supplies a diagnostic program to confirm hardware operation and to perform a communication test with equipment.
• Max. 16 boards can be installed as configured in the range COM1 - COM256.

  • Up to 16 boards can be mounted on a single PC. COM1 - COM256 can be set using the device manager.
• Each channel is equipped with separate 128-byte FIFO buffers for transmit and receive.

  • Employed a buffer memory 128-byte dedicated to transmission and 128-byte for each channel. These are FIFO format, useful for high speed communications and to reduce the load to the CPU when transmitting/receiving. As the device manager can be used to enable/disable the use of FIFO and set the FIFO trigger size, you can build an optimum system according to your use.
