Overview
The
SyncLink
GT2
and
GT4
Serial
Adapters
are
add
‐
in
cards
for
use
in
systems
with
a
PCI
expansion
slot.
The
cards
provide
two
(GT2)
or
four
(GT4)
serial
ports
for
use
by
the
system.
A
variety
of
serial
protocols
and
interface
standards
are
supported.
Refer
to
the
software
documentation
included
with
the
card
for
details
on
using
the
card
for
a
specific
application.
