Description
USB to 2 Serial / 1 Parallel
The Kawasaki USB to 2 Serial / 1 Parallel enables your system to have the capability to communicate
between the USB (Universal Serial Bus) port and 2 serial ports and 1 parallel port. This device meets the
USB 1.0/1.1 and IEEE1284 specifications. All the advantages of USB are available to peripherals with
parallel and serial port interface. With Kawasaki’s USB to 2 Serial / 1 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 compatibility solutions.
