2-port RS232 to USB Converter US$82.00

Multi-2U/RS232
2-port RS232 to USB Converter


  • Add two serial RS232 ports to your PC easily
  • Serial communication speed of up to 921.6Kbps
  • USB 2.0 compatible (Hi speed)
  • Operates by USB bus power (requires no external power)
  • RI signal line power supply
  • Built in 15kV ESD
  • Communication status via TX/RX LED
  • Windows 2000/XP/2003/Vista/2008/7, Linux OS device driver
  • The Multi-2U/RS232 Converter enables the connection of two asynchronous serial devices such as terminals, modems, printers, and scanners to a PC.

    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-1U/RS232 supports two RS232 interfaces. The RS232 transceivers have 15kV ESD protection.
