Updated July 14, 2008 Cash drawers The SurePOS 720 are preconfigured from the factory to work correctly with all IBM cash drawers. In this automatic mode, the system can correctly detect the difference between IBM 24-V and IBM 38-V cash drawers. Cash drawer port 3A provides auto-sensing function for an IBM cash drawer. Note: Automatic mode sets the cash drawer operating voltage for both cash drawer ports. If you connect a 24-V cash drawer to port 3A and connect a second drawer, it must also be a 24-V drawer. If you are using a non-IBM drawer, the automatic mode will not work correctly, and damage to either the cash drawer, system unit, or both is possible. If a customer has two connected cash drawers, both drawers must be the same voltage. You can configure the cash drawer voltage (24 V or 38 V) by using the configuration options on the POS configuration setup program or with the jumper override. Figure 11 shows the location of the cash drawer voltage jumper on the riser card and a diagram with the position of the jumpers. JP2 JP3 3 2 1 Figure 11.

Cash
drawers
The
SurePOS
720
are
preconfigured
from
the
factory
to
work
correctly
with
all
IBM
cash
drawers.
In
this
automatic
mode,
the
system
can
correctly
detect
the
difference
between
IBM
24-V
and
IBM
38-V
cash
drawers.
Cash
drawer
port
3A
provides
auto-sensing
function
for
an
IBM
cash
drawer.
Note:
Automatic
mode
sets
the
cash
drawer
operating
voltage
for
both
cash
drawer
ports.
If
you
connect
a
24-V
cash
drawer
to
port
3A
and
connect
a
second
drawer,
it
must
also
be
a
24-V
drawer.
If
you
are
using
a
non-IBM
drawer,
the
automatic
mode
will
not
work
correctly,
and
damage
to
either
the
cash
drawer,
system
unit,
or
both
is
possible.
If
a
customer
has
two
connected
cash
drawers,
both
drawers
must
be
the
same
voltage.
You
can
configure
the
cash
drawer
voltage
(24
V
or
38
V)
by
using
the
configuration
options
on
the
POS
configuration
setup
program
or
with
the
jumper
override.
Figure
11
shows
the
location
of
the
cash
drawer
voltage
jumper
on
the
riser
card
and
a
diagram
with
the
position
of
the
jumpers.

jumper
settings
for
the

V
and

V
cash
drawers:
