概要・特点

This product is a low profile sized PCI Express bus-supported card designed for extending RS-422A/485 compatible serial communication functionality on your PC.
The product has two RS-422A/485 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 128-byte built-in FIFO buffer for transmission and reception of each channel, the product supports a baud rate of up to 921,600 bps.
It also comes with a Windows driver, which allows cards to be used as OS-standard COM ports.

• Max. 921,600bps RS-422A/485 Serial Communication

  • The product has two RS-422A/485-standard serial ports. Baud rates from 30 to 921,600bps can be set.
• Possibly used as Windows-standard COM ports.

  • Comes with a driver software that allows the products to be used under Windows 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. In addition, supplies a diagnostic program to confirm hardware operation and to perform a communication test with equipment.
• Isolation between PCs, surge protection for all signal lines

  • Between PCs are electrically isolated.
    As isolation of the bus is provided, this prevents electrical noise 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 COM1 - 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.

  • 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.
• Support for Low Profile size slot / standard size slot

  • Bundled with each bracket for Low Profile size slot / standard size slot.
    Exchanges it for the standard size bracket when mounting on the standard size slot.
