Alpha VS 100 - VS-100 Module Installation Guide

[EP^2:
Installing
the VS-100
To operate, the VS-100 needs
three
components:
the
power supply,
the speaker, and the VS-100
module-
Follow
the
step by step
instructions below to install
them.
Turn the
computer
off
.
Plug
the
speaker
into the
VS-100
(larger
jack)
If you
AREN'T
using an Alpha Products
speaker, you
may
connect
any
small 8 ohm speaker
using
a
1/8"
plug,
(Radio
Shack
part
number
274-286).
The
VS-100
is
not
designed to
drive
large stereo speakers.
Plug the
power pack into
a wall
outlet
or
preferably
a
power
strip with the rest of
your
computer
equipment.
•U.S.
version:
The power pack
takes
standard
115V
AC
and
converts
it to a low
DC voltage
<8-12
volts).
•Foreign:
You
will
need to supply a
power
pack
that
converts 220V
AC to about 9V
DC
filtered.
It must
supply
at least
100
mill i Amperes
. The power
jack on
the VS-100
is
either a 2.5 mm
or
a
3.5
mm
plug
(depending on
the power supply we are
currently
using).
The tip should
be positive <+).
Please be
careful,
reversing
the
polarity may
damage
your
unit.
Plug the VS-100
into your computer.
Before you do
so,
it is a good
idea to
carefully
clean
the card edge
on the computer.
Radio Shack
card
edges
are not
gold
plated and some
oxidation
may
create
contact
problems. Use
a pencil
eraser
to rub
both
sides
of the board,
then wipe
them
with a
cloth,
preferably
one dampened
with rubbing
alcohol.
Model I
with
expansion
interface!
Plug
the VS-100
on the
left
side of the
expansion
interface
in
the 40
pin bus
located
in front
of the
parallel
printer
port.
The board
should
extend downwards
from the
connector.
NOTE
1: Most
expansion
interfaces
have
large
rubber
feet. If
yours
doesn't, you
will
have to
raise
it
