Pathway #1002 eDIN Opto-Splitter - Manual

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 opera-
tional and DMX data is being transmit-
ted.

eDIN Model Descriptions
Specifications
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.

THRU IN IN
DMX Termination
If only one eDIN Opto-Splitter is used,
and nothing is connected to the DMX
THRU connector, the termination switch
must be set in the ON position to
terminate the incoming DMX signal from
the console. If several eDIN optos are
connected together using the DMX
THRU connector on each unit, only the
last eDIN opto in the chain is terminated,
all the others are not terminated (switch
in the OFF position).
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.
To ensure trouble free operation,
DMX512 standards require 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
mandatory. A Pathway eDIN Opto-
Splitter 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.
Operational Philosophy
• All wiring must be in a continuous run,
daisy-chained, no “Tees” are permitted
• “Stars” are permitted only in
conjunction with a repeater
• Cable shield may be earth-grounded
at one end only: at the control console
output and the eDIN opto outputs
• Maximum length of one 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 1: Common
Pin 2: Data (-)
Pin 3: Data (+)
Pin 4: Optional Data (-)
Pin 5: Optional Data (+)
• 3 pin XLR type connectors are a non-
standard alternative:
Pin 1: Common
Pin 2: Data (-)
Pin 3: Data (+)
• Wire must be Belden 9842 (120Ω),
9829 (100 Ω), ISO/IEC 11801 (Cat5)
or equivalent
• A maximum of 32 DMX receiving
devices can be present on a single
DMX line

ANUAL
eDIN Opto-Splitter
Model# 1002
An essential component of any
DMX512 distribution system, the
eDIN Opto-Splitter permits star
wiring installations while isolating
an d p ro t ect i n g co nn ect ed
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.
