Introduction
Your
new
DM8112CX
solid
state
data
display
is
a
precision
engineered
product
designed
for
use
with
the
computer
system
which
outputs
a
composite
video
signal.
This
picture
tube
employs
an
implosion
proof,
green
phosphor.
This
data
display
is
equipped
with
DC
restoration
(In
the
absence
of
a
data
signal,
the data display
screen
will
be
fully
black:
no
raster).
Solid
state
electronics
used
in
the
DM8112CX
provides
improved
reliability
and
superior
performance
even
in
continu-
ous
duty
applications.
