Configuring
the
Omninet/4
Transporter
Card
Your
Omninet/4
Transporter
card
has
switches
that
let
you
set
values
for
four
of
its
operating
characteristics.
Before
you
install
the
card,
you
will
at
least
have
to set
the
device
address
for
your
computer.
You
should
also
check
the
other
switch
settings
and
change
them
as
needed
or
confirm
that
they
are
correctly
set
to
their
default
values.
GENERAL INFORMATION
Switch-selectable
values
on
the
Omninet/4
Transporter
card
include
•
Network

address
and
speed
•
Memory
base
address
•
I/O

Interrupt

The
Omninet/4
Transporter
card's
dual-port
memory
uses
16
kilobytes
of
your
computer's
address
space.
The
dual-
port
memory,
accessible
by
both
the
Transporter
card
controller
device
and
the
host
computer,
is used
for
the
exchange
of
data
moving
to
and
from
the
network.
The
memory base address is
the
starting
address
of
this
16-
kilobyte
block
of
addresses.
Similarly,
the
Transporter
card
requires
I/O
addresses
through
which
to
exchange
command
and
status
informa-
tion
with
the
host
computer.
The
I/O
base address is
the
first
address
of
a
block
of
16
I/O
addresses
that
the
card
uses.
The
interrupt request line is
the
means
by
which
the
Transporter
card
signals
the
host
computer
when
action
on
the
part
of
the
host
is
required.

No
two
devices
in
a
computer
can
share
the
same
memory,
I/O
addresses,
or
interrupt
request
lines
at
the
same
time.
The
Omninet/4
Transporter
card
uses
the
following
default
memory,
I/O
addresses,
and
interrupt
request
line:

It
is possible
for
conflicts
to
occur
between
a
Transporter
card,
EMS
cards,
tape
controllers,
modem
or
asynch
cards,
or
SCSI
con
trollers.
You
should
compare
the
Transporter
card
default
values
with
those
for
memory,
I/O
address,
and
interrupt
request
lines
used
by
other
devices
in
the
computer
to
determine
whether
there
are
any
conflicts.
If
that
information
is
not
available,
you
can
install
the
Transporter
card
and,
before
you
attach
the
computer
to
the
network,
check
to
see
that
the
other
devices
are
still
working
correctly.
If
they
appear
to be
working
properly,
there
may
be no
conflicts;
however,
it
is possible
that
conflicts
may
occur
only
under
particular
circumstances.
You
can
change
the
memory
base
address,
the
I/O
base
address,
or
the
interrupt
request
line
on
the
Transporter
card
as necessary.
These
values
should
be
changed
only
if
your
network
operating
system
will
permit
the
changes.
The
locations
of
the
switches
for
changing
these
values
and
their
meanings
are
shown
in
Figure
2.
NETWORK

(NODE)
ADDRESS AND
SPEED
The
switch
for
setting
the

of
the

accessible
through
a
cutout
in
the

as
illustrated
in
Figure
1 below.
Allowable
addresses
are
0

must
be
different
from
the

sure
that
the

correctly.
One

network
will
prevent
the
