8-port RS232 to USB Converter US$178.00

Multi-8U/RS232
8-port RS232 to USB Converter


  • Eight serial RS232 ports per board
  • Serial communication speed of up to 921.6Kbps
  • USB 2.0 full speed (12M bits/second) compatible
  • Operated by USB bus power (no external power supply required)
  • External power supply via RI signal line to serial peripherals
  • Built-in 15kV ESD protection
  • TX/RX LED status display
  • Windows 98/CE/2000/XP/Vista/2008/7, Linux Kernel 2.4 or greater, Mac OS X, Mac OS9, Mac OS 8.6 driver support
  • The Multi-8U/RS232 Converter enables the connection of up to eight asynchronous serial devices such as terminals, modems, printers, and scanners to make a PC an economical but a powerful multi-serial device system. TXD and RXD LEDs are included in the case for the display of data transmission.

    Data speeds up to 921.6Kbps per port are supported. Another remarkable feature is in its specialized design which allows the RI pin (pin #9) of the serial DB-9 connector to be used in conjunction with an external power adapter to provide power to the unit and external devices as needed. This feature can be fully exploited when connecting small peripherals such as cash registers, barcode readers, or receipt printers to systems like PC POS.

    RS232 Interface Support

    The Multi-8U/RS232 supports eight RS232 interfaces. All the RS232 transceivers have 15kV ESD protection.
