概要・特点

This product is an isolated PCI bus-supported board designed for extending RS-232C compatible serial communication functionality on your PC. COM-4P(PCI)H has four 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 device driver is supported with this product.

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

  • The COM ports of this product support up to 921,600 bps. COM-4P(PCI)H has four RS-232C-standard serial ports.
• 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 boards in environments where you are concerned about surges causing incorrect operation or damage to the PC.
• Possibly used as Windows, Linux-standard COM ports

  • Combining the product with our device driver COM-DRV makes it possible to use the product in the same manner as the COM ports of a PC. This product supports communication using DCB structures in the Win32 API and Linux-standard system calls.
• Up to 16 boards can be installed

  • Up to 16 boards of the same model can be mounted on a single PC.
• Each channel is equipped with separate 128-byte FIFO buffers for transmit and receive

  • Equipped with a buffer memory for transmitting 128 bytes and receiving 128 bytes for each channel. These are FIFO format, useful for high speed communications and to reduce the load to the CPU when transmitting/receiving.
• The control line for RS-232C can be controlled and monitored by software

  • The control lines for RTS, CTS, DTR and DSR can be controlled and monitored using software.
