Description
USB Combo - Serial & Parallel
The Kawasaki USB to Parallel / 2Serial enables your system to have the capability to communicate
between the USB (Universal Serial Bus) port and parallel port and 2 serial ports. This device meets the
USB 1.0/1.1 and IEEE1284 enhanced parallel port and standard serial port specifications. All the
advantages of USB are available to peripherals with parallel and serial port interface. With Kawasaki’s
USB to Serial/Parallel device and software, it is transparent to the peripheral and no firmware changes
are required which makes it possible to convert peripherals with serial and parallel interfaces to USB
interface with minimum modifications. This device is ideal for Legacy solutions.
