eDIN Opto-Splitter

Model# 1002

CONTROL CONSOLE

eDIN Opto eDIN Opto

Typical Application

CAUTION!

eDIN modules are designed to work
on voltages from 9-30 volts AC or DC
only. DIN rail power supplies are
readily available from Pathway and
most electrical suppliers.

Each eDIN opto consumes 5 watts of
power.

DMX Termination

If only one eDIN Opto-Splitter is used,
and nothing is connected to the DMX
THRU connector, the terminati on switch
must be set in the ON position to
term i nat e t he i nc omin g D MX s ig nal f r om
the console. If several eDIN optos are
connected together using the DMX
THRU connector on each unit, only the
last eD I N opto i n th e ch ai n i s t erm i na t ed ,
all the others are not terminated (switch
in the OF F p ositio n).

DMX receiving devices such as dimmers
or scrollers are generally provided with a
termination switch, termination jumper or
other means of connecting the required
termination resistance across the DMX
line. Always make sure that the last
receiving device connected to any output
line is properly terminated.

THRU ININ

Indicators

The POWER LED on the face of your
eDIN Opto-Splitter will illuminate when
power is connected to the unit. There is
no on/off switch.

The DATA IN LED will illuminate and
flicker rapidly to indicate that DMX data
is being received.

Each DMX output has an associated
LED to show that the output is opera­tional and DMX data is being transmit­ted.

An essential component of any
DMX512 distribution system, the
eDIN Opto-Splitter permits star
wiring installations while isolating
and protecting connected
equipment from harmful electrical
faults. Pathway eDIN optos
feature self-healing protection
devices on all ports to prevent
internal damage when severe
faults of up to 250V are
accidentally applied to the
connected DMX cabling.

Operational Philosophy

To ensure trouble free operation,
DMX512 standards require that DMX
devices be installed in a daisy chain,
wit h no tees, wyes or s tars i n th e DMX
wiring. However, site conditions may
make star wiring desirable or even
mandatory. A Pathway eDIN Opto­Splitter permits star wiring by making
each branch of the star function
electrically as its own entity, unaffected
by the other branches of the star.
Additionally, opto-isolation circuitry
prevents ground loops or accidental
damage to control consoles from fault
voltages on DMX lines.

DMX Basics

• All wiring must be in a continuous run,
daisy-chained, no “Tees” are permitt ed

• “Stars” are permitted only in
con junction with a rep eater

• Cable shield may be earth-grounded
at one end only: at the control console
output and the eDIN opto outputs

• Maximum len g t h of o n e cable segment
is 1,800 ft. (550m).

• Receiving devices have male
connectors, transmitters have female

• The last DMX device on the line must
be terminated with a termination
switch or resistor with a value of 100 to
120 ohms between pins 2 and 3.

• 5 pin XLR type DMX connectors are
standard:

Pin 2: Data (-)
Pin 3: Data (+)
Pin 4: Opti onal Data (-)

Pin 1: Common

Pin 5: Opti onal Data (+)

• 3 pin XLR type connectors are a non­standard alternative:

Pin 2: Data (-)
Pin 3: Data (+)

Pin 1: Common

• Wire must be Belden 9842 (120Ω),
9829 (100Ω), ISO/IEC 11801 (Cat5)
or equivalent

• A maximum of 32 DMX receiving
devices can be present on a single
DMX line

Location

eDIN optos are designed for installation
in an application appropriate NEMA en­closure.

DIN Rail Mounting

The eDIN Opto-Splitter is designed to be
mounted on a section of 35mm DIN rail
secured to the inside of an appropriate
enclosure. The DIN rail included with
the eDIN opto can be used if only one
eDIN opt o is b ein g used . If sever al eDI N
devices are being mounted, you can use
a longer section of 35mm DIN rail, read­ily available from Pathway as well as
most electrical suppliers.

eDIN modules have no mounting restric­tions with regards to positioning within
an enclosure. Modules can be mounted
side-by-side in a continuous row or
spaced out. Clearances between the
modules and the side of the enclosure
are si mil arly st ri ctly a ma tter of avail abl e
space and personal preference. It’s up
to you.

Attach either your own or the enclosed
sect i o n of 3 5 mm DIN r ai l t o t he i nside of
you r enclo sure. Sec ure the eD IN mod­ule(s) by first engaging the top of the
eDIN module on the DIN rail. Then,
while pressing both of the release tabs
on the underside of the module, press
the bottom of the module into place.
When properly engaged, the module
should clearly ‘snap’ into place. Check
to ensure that the module as installed is
straight on the rail and the front of the
module should be parallel with the back
of the panel. If not squeeze the release
tabs hard while pulling up on the bottom
of t h e m o d ul e. On c e t h e m od u l e i s f r ee,
repeat the installation process until the
module is correctly and securely in­stalled.

Alternate Mounting

If you do not wish to take advantage of
the DIN r ail m ounti ng sy stem, the eDI N
module can be mounted in a more con­ventional manner by installing it without
the plastic DIN case. To remove the
plastic case, simply pry the right (or left)
end cap off of the case. You may have
to work the end back and forth to get it
apart. Once the end cap is removed, the
circuit board should slide out.

Use four 0.5” standoffs mounted on 4 x

3.75” centers to install the circuit board
in your enclosure. Make sure that the
components on the underside of the cir­cuit board do not come in contact with
your panel.

Connection Wire

Be sure to use the appropriate wire for
all connections.

DMX Connections: Belden 9829,

9842, Cat5 or equivalent.

Power Connections: Insulated #18-

16 AWG wire, stranded or solid.

DMX Connections

Typically, Pathway DMX Opto-Splitters
are used in the following configuration:

• DMX IN is connected to the control

console DMX output

• DMX OUTs are connected to the

remote DMX devices or receptacles
for the equipment receiving the
console signal. These may be
dimmers, scrollers or moving lights,
for exam ple.

• DMX THRU passes the console

signal to additional eDIN DMX opto­splitters or other similar devices, and
would in turn be connected to DMX
IN on the next unit in line.

WARNING!

All DMX input/output ports must only
be connected to low-voltage data
lines. Do not connect high voltage
sources to these connectors.

Recommended Wiring
Practice

Keep all DMX cabling away from high
voltage/power cables to maintain data
integrity. Wire must be Belden 9842
(120Ω), 9829 (100Ω), ISO/IEC 11801
(Cat5) or equivalent.

Power Con nections

eDIN modules require 9-30 volts, AC or
DC. Each eD IN Opto-Splitter co nsumes
5 watts of power, so size your power
supply accordingly.

With the external power supply turned
off, connect the power leads to one pair
of V+ and V- terminals. Polarity should
be observed if a DC supply is used.

If additional DIN modules are powered
from the same supply, the power may be
daisy-chained using the second pair of
V+ and V- terminals as a ‘thru’ connec­tion.
