Chapter 1: Product Overview 1-13
The
wired
Ethernet
connection
is
not
certified
for
use
in
configurations
where
a
wireless
adapter
is
installed.
Universal Serial Bus
The
Summa
POS
Motherboard
provides
three
ports,
one
of
which
is
reserved
for
integrated
devices
(not
externally
accessible).
Only
two
of
the
three
USB
ports
on
the
Summa
POS
Motherboard
can
be
active
at
the
same
time.
If
the
internal
auxiliary
USB
port
is
enabled,
one
of
the
two
ports
on
the
main
connector
row
becomes
disabled.
This
functionality
is
controlled
through
the
BIOS
setup
menu.
Note:
USB
peripherals
require
support
from
the
operating
system,
which
is
currently
limited
to
Windows
98.
Serial Ports
The
Summa
POS
Motherboard
provides
two
RS
‐
232
ports
(9
‐
pin
D
‐
shell
connectors,
Ports
1
and
2)
directly
on
the
Motherboard
and
supports
two
additional
RS
‐
232
ports.
Ports
3
and
4
require
an
optional
harness
connection
to
the
Motherboard.
Ports
1
and
3
can
be
supplied
with
+12
V
DC
on
Pin
9
when
properly
set
up
in
the
BIOS.
The
total
power
drawn
by
Ports
1
and/or
3
must
be
no
greater
than
1
amp
at
+12
V
DC.
Refer
to
the
following
table
for
RS
‐
232
pinout
information.
The
BIOS
provides
flexibility
in
mapping
resources.
However,
a
fully
‐
loaded
system
(2
PCMCIA
cards
that
require
IRQs,
four
serial
ports
in
use,
USB
in
use,
parallel
port
in
use,
and
MSR)
may
not
have
enough
available
IRQs
to
support
all
serial
ports.
Use
a
USB
serial
port
expander
to
overcome
this
PC
architecture
limitation.
