概要・特点

It is the interface card of the PCI bus conformity which expands the RS-232C serial communication port of four channels in a personal computer. It can mount also in a standard PCI slot by bracket (appending) change. UART162850 of 128byte FIFO is carried according to each channel and transmission and reception. It can be used as a Windows and standard COM port for Linux by the setup by the attached standard COM driver. A program is also possible at a Win32 API communication function or MSComm. * 9 pin D-SUB connector distribution cable option

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

  • This product has four 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 bundled driver library

  • 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 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.
