Introduction
The
TD
‐
1580
and
TD
‐
1581
pair
together
to
form
a
powerful
balanced
serial
data
transport
solution.
The
DB
‐
25
connectors
are
pinned
out
to
directly
support
an
EIA
‐
530
serial
link.
However
due
to
the
transparency
and
flexibility
of
the
design,
the
TD
‐
1580/81
can
be
used
as
6x4
independent
6
Mbps
RS
‐
422
channels
and
2x1
independent
256
Kbps
RS
‐
232
channels.
This
incredible
versatility
can
solve
a
myriad
of
serial
data
communications
problems.
Your
once
limited
serial
links
can
not
only
be
consolidated
but
extended
to
over
20
Km
on
a
single
fiber
pair.
SCADA
(supervisory
control
and
data
acquisition),
Telecommunications,
Facility
Automation
and
Control,
even
DMX
Lighting
control
applications
can
all
benefit
from
the
TD
‐
1580/81.
For
more
advanced
systems,
a
‘Regeneration’
switch
on
the
TD
‐
1581
allows
users
to
toggle
between
synchronous
applications
that
require
Send
Timing
(ST)
and
asynchronous
or
synchronous
applications
that
require
Terminal
Timing
(TT).

Phoenix™
Theory
of
Operation
By
using
a
technology
unique
to
FiberPlex
products
called
‘transparency’,
we
are
able
to
use
all
the
clock,
data
and
control
channels
of
the
standard
EIA
‐
530
interface
completely
independently
of
one
another.
This
provides
the
ability
to
have
(4)
bi
‐
directional
RS
‐
422
serial
with
(2)
unidirectional
RS
‐
422
and
(1)
bi
‐
directional
RS
‐
232
with
(1)
uni
‐
directional
RS
‐
232,
or
even
independently
as
(6)
RS
‐
422
in
one
direction
and
(4)
in
the
other
[6x4]
and
(2)
RS
‐
232
in
one
direction
and
(1)
in
the
other
[2x1].
The
table
later
in
the
manual
shows
how
these
channels
are
pinned
out.
Differences
between
TD
‐
1580
and
TD
‐
1581
The
TD
‐
1580
has
a
female
(sockets)
DB
‐
25
connector
and
mates
with
the
DTE.
The
TD
‐
1581
has
a
male
(pins)
DB
‐
25
connector,
mates
with
the
DCE
and
has
clock
regeneration
functions.
Getting
Started
Initial
Inspection
Immediately
upon
receipt,
inspect
the
shipping
container
for
damage.
The
container
should
be
retained
until
the
shipment
has
been
checked
for
completeness
and
the
equipment
has
been
checked
mechanically
and
electrically.
If
the
shipment
is
incomplete,
if
there
is
mechanical
damage,
or
if
the
unit
fails
to
operate
notify
FiberPlex
and
make
the
shipping
materials
available
for
the
carrier's
inspection.
