The
Wedge
controller
consists
of
a
microcontroller
and
associated
circuitry
that
permits
(via
a
“PC

keyboard
interface)
the
Touch

LCD
to
support
the
following
peripheral
devices:
•
MSR

a
three

The
controller
logically
connects
these
devices
in
series
with
a
standard
PC
keyboard.
The
retail
workstation
or
PC
interprets
the
data
flow
as
keyboard
input.

can
be
connected
externally

the
5964
whenever

is
required
