MOUNTING
OPERATIONAL PHILOSOPHY
An essential component of any DMX512
distribution system, the use of eDIN Installation
Repeaters permits star wiring while isolating and
protecting connected equipment from harmful
electrical faults. Pathway eDIN Installation
Repeaters
feature self-resetting protection
devices on all ports to prevent internal damage
when severe faults of up to 250V are accidentally
applied to the connected DMX cabling.
To ensure trouble-free operation, DMX512 standards re-
quire that DMX devices be installed in a daisy chain, with
no tees, wyes or stars in the DMX wiring. However, site
conditions may make star wiring desirable or even man-
datory.
A Pathway eDIN Installation Repeater provides up to 4
eDIN opto-splitter cards, for a total possible 16 output
branches. Each branch acts electrically as its own entity,
unaffected by faults on other branches of the star.
Opto-isolation circuitry prevents ground loops or damage
to control consoles by fault voltages on DMX lines.
CONNECTIONS
Pathway eDIN Installation Repeaters are delivered with
the power supply pre-wired to the first opto card, and with
all required wiring daisy-chained to any additional cards.
The following connections must be done on-site.

Pathway eDIN Installation Repeaters are designed for
indoor use in a dry location. Mount the Installation Re-
peater to the wall with appropriate fasteners. Run conduit
into the box through the knockouts provided, ensuring
that line voltage wiring is kept inside the barriered power
supply section.
WARNING
All DMX input/output ports must be
connected to low-voltage data lines only. Do
not connect high voltage sources to these
connectors.
DMX IN is wired to the control console output or DMX
source.
DMX OUTs are connected to the remote DMX devices or
the receptacles for the equipment receiving the console
signal. These may be dimmers, scrollers, or moving
lights, for example.
Power. With the power off, make the appropriate con-
nections to Ground, Neutral and Line of the power supply
in the barriered section at the top of the cabinet.
