AcuityBrands PWREP WM Installation Opto Splitter
Installation
An essential component of any DMX512 distribution system, the use of Pathway Wall-mount Installation Repeaters permits star wiring while isolating and protecting connected equipment from harmful electrical faults. The Wall-mount DIN 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.
OPERATIONAL PHILOSOPHY
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 mandatory.
A Pathway Wall-mount Installation Repeater provides up to 4 DIN-mount opto-
splitter devices, 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.
MOUNTING
Pathway Wall-mount DIN 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.
CONNECTIONS
Pathway Wall-mount Installation Repeaters are delivered with the power supply
pre-wired to the first DIN splitter, and with all required wiring daisy-
chained to any additional cards. The following connections must be done on-
site.
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.

RECOMMENDED WIRING PRACTICE
Keep all DMX cabling away from high voltage/power ca-bles to maintain data integrity. Use the appropriate wire for all connections.
- DC Power Connections: Insulated #18-16 AWG, stranded or solid core
- DMX wire cable shield may be earth-grounded at one end only, preferably at the control console.
- 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 pin 2 and 3. RDM capable ports are self-terminated automatically.
EXPANSION INSTRUCTIONS
DIN Installation Repeaters may hold up to two opto-splitter cards (PWREP WM
[xxxx] SML) or four cards (PWREP WM [xxxx] MED). If the original enclosure
holds less than its limit, it is possible to add cards. It’s also possible to
pass through data and low voltage power to a second enclosure.
DMX THRU is wired to the DMX IN connector on the ad-ditional module. While not
isolated, DMX THRU can also be used to pass signal to other devices.
Power can also be daisy-chained using the second pair of V+ and V- terminals.
Polarity should be followed at the receiving device.
WARNING: Always disconnect main power before removing the enclosure’s cover. DIN Installation Repeaters are designed to operate on a mains voltage of 120-277 volts AC.
DMX TERMINATION
If nothing is connected to the DMX THRU terminal block of the final opto-
splitter card, then the termination switch on this card must be set to the ON
position. All the other cards are not terminated (switch in the OFF position).
If another card is added, or the signal is passed through to another device,
the switch on the final card will need to be moved to the OFF position and the
termination applied at the new final device. Always make sure the final re-
ceiving device connected to any output or branch line is properly terminated
using its internal switch or jumper or if necessary a resistor of 120 Ω
between pins 2 and 3.
INDICATORS
The face of each card inside the Installation Repeater has the following LEDs:
- The Power LED will illuminate when power is connected to the card. There is no on/off switch.
- The DMX IN LED will illuminate and flicker rapidly when DMX data is being received.
- Each DMX output has a DMX OUT LED that will illu-minate and flicker when DMX is being output by that branch.
