USAR Protocol Interpreter family product specifications
Description The USAR SunAdapt is a single IC that converts any off-the-shelf or proprietary PS / 2 human input device, such as a keyboard, mouse, touch screen, barcode scanner to a Sun-compatible system. This IC was designed for the SunAdapt protocol interpreter - a single box that emulates all the functions of a PS / 2 system keyboard controller on one end and provides output for a Suncompatible keyboard and mouse on the other. The IC allows an external PS / 2 keyboard, an external PS / 2 Mouse and a Sun mouse to operate concurrently. A Sun keyboard may also operate with a PS / 2 mouse and Sun mouse as long as the PS / 2 keyboard has been unplugged. The PS / 2 devices may be hot-plugged. No additional software drivers or hardware, including a power supply is needed. Features · Interfaces PS / 2 data to Sun · Some devices can be used concurrently · PS / 2 devices can be hot-plugged Applications · System Legacy Support Pin Descriptions · Available in DIP, PLCC and Quad Flat packages · Custom versions available in small or large quantities

Descri
Connection Guide for the USAR SunAdapt Protocol Interpreter The USAR SunAdapt has three ports. I symbol, denoting the type of device that may be plugged in, is situate above each of these ports. Be sure to connect the right device to the right port. The symbols identify the following: PS / 2 mouse PS / 2 keyboard Sun mouse and keyboard. Turn off the power of Sun system. Plug the cable of USAR SunAdapt into Sun input device port. You may then connect your keyboards and mice in one of the two ways. 1. Connect the PS / 2 mouse to PS / 2 mouse port on the USAR SunAdaptTM. Connect the PS / 2 keyboard to PS / 2 keyboard port of USAR SunAdaptTM. Connect a Sun mouse to Sun keyboard / mouse port. The Sun keyboard data is blocked. 2. Connect the PS / 2 mouse to PS / 2 mouse port on the USAR SunAdaptTM. Connect a Sun keyboard to Sun mouse / keyboard port of the USAR SunAdaptTM. In this situation, there is no PS / 2 keyboard, the Sun keyboard data will pass through. Make sure all the connections are correct. Now you can turn on the power and USAR SunAdapt will work properly.
