1-1 INTRODUCTION
The AS/2 is a high performance and low cost printer sharing device
which can operate in either auto switching mode or manual switching mode.
The AS/2 has buffer card option. In the auto switching mode the AS/2 automat
ically locks on and services the source device that requests to link to the
common destination device. However, in the manual switching mode the AS/2
works exactly the same way as the conventional data switch.
1-1-1 AS-401PII
AS-401PII is a 4-input-1-output Centronics auto switch, which does not
require additional power supply should no buffer card installed and needs DC
9V adapter If installed. Also, it is not AS/2-WARE supported.
1-1-2 AS-402PII
AS-402PII is a 4-input-2-output Centronics auto switch, and is AS/2-
WARE supported, which enables user to choose output port by simple Hot Key
controls. AS-402PII is powered by one DC 9V adapter with or without buffer.
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 ard rear views.
