OVERVIEW

Pathway eDIN Opto-Splitters are an essential
component of DMX512 distribution systems,
permitting star-wiring while protecting
connected equipment from electrical faults.
The DIN form factor makes installation fast and
easy.

CONNECTIONS

eDIN Opto-Splittes feature terminal strips that can be re­moved from the module to facilitate wiring. Make the fol­lowing connections, WITH THE POWER TURNED OFF:

POWER

The module will run on a range from 9 to 30 VDC at
500mA per card connected. Observe the correct polarity
when connecting to the V+ and V-. A second set of termi­nals are provided on the connector to daisy-chain power
to other eDIN modules. A grounding terminal is also pro­vided for connection to earth ground.

DMX

DMX connections consist of a shield and one or two data
pairs. The two DMX IN usually come from control con­soles, architectural controllers or opto-splitters. DMX
THRU pins on each connector may be daisy-chained to
the DMX IN of other eDIN modules or other DMX equip­ment. DMX OUT sends the merged signal and is con­nected to the DMX inputs of the appropriate downstream
devices.
Connect the DATA+ and DATA– wires to D1+ and D1­respectively for each of DMX A, DMX B and DMX OUT.
Observe the same polarity convention throughout the sys­tem. Connect the cable shield to the SHLD COM terminal.

STATUS INDICATORS

POWER Blue. Glowing steadily indicates power

supply OK; off indicates no power.

DMX IN/ OUT Amber. Glowing steadily indicates DMX is

present; off indicates no incoming DMX

DMX ISO Red. Glowing steadily indicates the isolat-

ed power supply for the outputs is OK.

DMX TERMINATE

The rules of DMX require the last device on a DMX line
be terminated with a 120Ω resistor between pins 2 and 3
to prevent signal reflection. If there is no connection to
the DMX THRU terminals, the DMX Terminate switch
should be ON. If there are other devices connected to the
DMX THRU terminal, the DMX Terminate switch should
be OFF and termination be applied to the final device in
the daisy-chain.
