COMMUNICATION
The
Falco 5000 comes stan-
dard with
three
serial ports
and
one
parallel port. All
three serial ports can
be
used
as
online host ports, printer
ports
or
modem ports and can
be configured for either an
RS232C
or
RS422 interface.
This
is
done through cable
configurations.
The
Falco 500e, 5220e, 5600
and 5500e come with two
standard serial ports.
An
expansion card
is
available for
the Falco 500e,5220e and
5600 for additional port
options.
Falco terminals come stan-
dard with a female communi-
cation port connector. A
gender changer may be
required at
some
installations.
The
12 pins
of
the communi-
cation interface listed below
carry signals either into
or
out
of
the
terminal. All pins, if
connected at the terminal, can
have
some
impact on
the
terminal's ability to communi-
cate properly.
Be
sure only
the pins required by your sys-
tem are connected to the ter-
minal.
