AS/2 Auto Switch 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 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.

The AS/2 tremendously improves the efficiency of your switching
applications. We suggest that you take a few moments to carefully read the
following instructions to ensure the maximum benefits and convenience your
AS/2 offers. The following figures are the AS/2's front views and rear views.
