Overview / Features

This product is a PCI bus-supported board designed for extending RS232C compatible serial communication functionality on your PC. The < COM-2(PCI)H > has two RS-232C 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. The COM-2(PCI)H board is backward compatible with the CONTEC COM-2(PCI) board. The COM-2(PCI)H can therefore replace the COM-2(PCI) in an existing system.

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

  • The < COM-2(PCI)H > has two RS-232C-standard serial ports. Baud rates from 2 to 921,600bps can be set. When using the bundled “Standard COM Driver Software” and “Driver library API-PAC(W32)”, baud rates from 15 to 921,600bps can be set.
• Possibly used as Windows, Linux-standard COM ports, using the supported driver library

  • Driver software is available for use on Windows / Linux in the same way as a COM port on a 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.
