Interface
On
the
rear
of
the
unit,
near
the
opticalCON
DUO
connector,
are
two
RJ
‐
11
jacks,
one
marked
“In”
and
the
other,
“Thru.”
These
support
a
proprietary,
115.2
kBaud
RS
‐
422
serial
protocol
that
enables
a
controlling
device
to
poll
the
status
of
connected
devices.
Up
to
255
units
can
be
daisy
‐
chained
on
one
link,
with
the
“In”
as
the
upstream
link
(eventually
leading
to
the
controller)
and
the
“Thru”
as
the
downstream
link.

The
pinouts
of
the
connectors
are
as
follows:
Connector

(to
the

3
TX

A
standard
crossover
RJ11
cable
can
be
used
to
daisychain
units
together.
For
the
WDM,
the
following
information
can
be
accessed:
Temperature
of
the
logic
board
and
power
supplies
Channel
status
(SFP
inserted,
signal
present,
transmit

Identification
of
SFP
models
and
manufacturer
Status
of
cooling
fans,
including
level
and
operational
status
Power
supply
Voltages,
temperatures
and
switching
frequency
