FUNCTION OVERVIEW

l-1 INTRODUCTION

The AS/2 is a high performance and low cost printer sharing device
which operates in either auto switching mode or manual switching mode. The
AS/2 allows

up to

four or eight source devices to share one common destination

devices. In the auto switching mode the AS/2 automatically locks on and

services the source device that requests to link with the common device.
However, in the manual switching mode the AS/2 works exactly the same way

as the

conventional

data switch.

There are four models, AS-41 1 P, AS-41 1S AS-81 1 P and AS-81 1 S all

belong to the AS/2 auto switch products. These differences can be quickly

understood by reading the following table.
