Overview / Features

This product is a PCI Express bus-supported card designed for extending RS-232C compatible serial communication functionality on your PC. It has two RS-232C-standard serial ports. Higher noise-resistant models with isolation between channels and between 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. It also comes with a Windows/Linux driver, which allows cards to be used as OS-standard COM ports.

  • Max. 921,600bps RS-232C Serial Communication
    • It has two RS-232C-standard serial ports. Baud rates from 2 to 921,600bps can be set for each port. 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 bundled driver software
    • Comes with a driver software that allows the cards 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.
  • Isolation between channels and between PCs, surge protection for all signal lines
    • The channels are electrically isolated from each other and from the PC. As isolation is provided between channels as well as isolation of the bus, this prevents electrical noise between channels as well as between the PC and external circuits. As surge protection is provided on all signal lines, you can safely use the cards in environments where you are concerned about surges causing incorrect operation or damage to the PC.
  • Max. 16 cards can be installed as configured in the range COM - COM256.
    • Up to 16 cards 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.
    • It put a buffer memory of 128byte for use of the transmission, and a buffer memory of 128byte for use of the reception on each channel. The buffer memory helps high-speed communication and CPU load reduction by data transmission and reception time in an FIFO form. It can set FIFO use presence, FIFO trigger size by device manager. It can realize the most suitable performance by doing the adjustment trigger size that accepted a system.
