FUNCTION OVERVIEW
1 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

belong to the AS/2 auto switch products. These differences can be quickly
understood by reading the following table.
