Note:
Bits
2
and
3
are
set
to
‘1’
by
each
device
reset.
The
cash
drawer
interface
can
be
diagnosed
remotely.
For
security
reasons,
the
cash
drawer
diagnostics
mode
must
first
be
activated
by
pressing
an
external
momentary
switch
(SW2).
The
intention
is
for
authorized
personnel
to
be
present
when
the
cash
drawer
diagnostic
tests
take
place.
There
is
only
one
cash
drawer
status
signal;
therefore,
bit
0
is
the
status
of
either
cash
drawer
or
both
cash
drawers.
