Pathway #1002 eDIN Opto-Splitter - Manual (Page 2)

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 example.
•
DMX THRU passes the console
signal to additional eDIN DMX opto-
splitters or other similar devices, and
would in turn be connected to DMX
IN on the next unit in line.
If you do not wish to take advantage of
the DIN rail mounting system, the eDIN
module can be mounted in a more con-
ventional 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 cir-
cuit board do not come in contact with
your panel.
Alternate Mounting
DIN Rail Mounting
Location
eDIN optos are designed for installation
in an application appropriate NEMA en-
closure.
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.
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 opto is being used. If several eDIN
devices are being mounted, you can use
a longer section of 35mm DIN rail, read-
ily available from Pathway as well as
most electrical suppliers.
eDIN modules have no mounting restric-
tions 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 similarly strictly a matter of available
space and personal preference. It’s up
to you.
Attach either your own or the enclosed
section of 35 mm DIN rail to the inside of
your enclosure. Secure the eDIN mod-
ule(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 the module. Once the module is free,
repeat the installation process until the
module is correctly and securely in-
stalled.
Connection Wire
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
(120
Ω), 9829 (100Ω), ISO/IEC 11801
(Cat5) or equivalent.

eDIN modules require 9-30 volts, AC or
DC. Each eDIN Opto-Splitter consumes
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’ connec-
tion.
