DMX Interface - PWREP DIN P4 RDM
4-Way DMX/RDM Repeater
Manual
08/30/21
The Pathway DIN-mount DMX/RDM Splitter supports the bi-
directional communications necessary for E1.20 Remote
Device Management in DMX512 installations requiring star-
wiring.
Full opto-isolation between all ports adds maximum
protection against common mode voltages or ground faults
for connected equipment.
The PWREP DIN P4 RDM features terminal strips that can be removed
from the card to facilitate easy wiring installation or replacement. Make
the following connections,
WITH THE POWER TURNED OFF
, and
observe ESD precautions by ensuring the installer is properly grounded
before handling the device.
POWER
The DMX/RDM Splitter is designed to run on a range of voltages from
9-30 volts DC. Each DMX/RDM Splitter requires 6 watts. Observe the
correct polarity when connecting to V+ and V-.
A second set of terminals are provided as a DC power-through
connection to other DIN devices. The EARTH GND terminal may be
connected to the enclosure’s chassis or electrical ground terminal to
improve EMC compliance.
DMX512
DMX connections consist of a shield and a data pair. An optional second
auxiliary data pair is also occasionally employed. DMX IN usually comes
from a control console, Pathport® Gateway, architectural controller or
opto-splitter. DMX THRU provides a means to daisy-chain DMX to other
DIN devices.
Connect DATA+ and DATA- to D1+ and D1– on the DMX IN terminal.
Connect the cable shield or common to the SHLD COM terminal.
Observe the same polarity convention throughout the system while
connecting the four outputs.
Connect wires for DATA2+ and DATA2– to D2+ and D2–, if desired. It
is not necessary to connect these wires for DMX or RDM to function.
OVERVIEW
CONNECTIONS
STATUS INDICATORS
A compliant RDM controller must be used to get and set RDM information
and commands. The PWREP DIN P4 RDM does not provide controller
functions, but simply allows RDM messages within a star-wiring network.
A Pathport Gateway and suitable software can be used to provide RDM
controller functions.
