Programming
the
DMAF2
Controller
Board
Before
installing
the
DMAF2
controller
in
your
computer
system
the
jumper
options
on
the
board
need
to
be
set
properly.
DO
NOT,
however,
change
the
adjustment
of
the
three
controls
near
the
top
of
the
board.
These
were
pre-set
at
the
factory
and
should
only
be
adjusted
by
qualified
service
personnel.
Jumper
changes
are
accomplished
by
moving
the
small
(probably
blue)
jumper
blocks
which
look
like
smajl
connectors.
A
complete
description
of
each
jumper
position
is
given
in
the
DMAF2
Controller
Board
Jumpers
section
of
the
computer
system
documentation
manual
(if
applicable).
In
most
cases
the
short
table
on
the
following
page
may
be
used
to
configure
the
board
for
your
particular
system.
Make
any
jumper
changes
necessary.
