Description
USB to 4 Serial Ports
The Kawasaki USB to 4 Serial enables your system to have the capability to communicate between the
USB (Universal Serial Bus) port and up to four serial port peripherals. This device meets the USB 1.0/1.1
and standard serial port specifications. All the advantages of USB are available to peripherals with serial
port interface such as plug and play capabilities. With the USB Standard of high-speed data transfers, this
device is ideal for connections to high-speed modems or ISDN terminal adapters. Kawasaki’s device and
software enable the USB interface to be transparent to the peripheral and requires no firmware changes.
This makes it possible for peripherals with serial interfaces to easily interface with USB with minimum
modifications. This feature is ideal for Legacy applications.
