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.

The PWREP DIN P4 RDM is internally terminated and does not require
any further termination at the device.
However, the last DMX device on each output leg must still be properly
terminated in accordance with the E1.11 DMX512-A standard, to ensure
correct device operation.
The DMX THRU connector is an active pass-through and fully supports
RDM. In e󰀨ect, it is a fth output port. If power is lost to the device, the
DMX THRU connector will no longer function.
Due to timing restrictions in the RDM standard, no more than seven
(7) PWREP DIN P4 RDM devices may be daisy-chained together in
one run.
ANSI E1.20 Remote Device Management (RDM) is an open standard
data protocol that provides DMX512-A networks with the option of bi-
directional communication (aka “talkback”). By using half-duplex data
communications, RDM operates over the same wire pair (pines 2 and
3) as DMX, ensuring backward compatibility with all DMX installations.
System layout is critical for successful use of the RDM standard.
Wire type and installation methodology must be correct as the timing
restrictions required by RDM are much more strict than for DMX.
RDM devices are classied as “controllers”, “responders”, or “in-line”
devices. Only one controller may be active on a given network. When the
controller issues a command, it listens for a response within a prescribed
time. During this period, “in-line” devices like the PWREP DIN P4 RDM
prepare to pass data back to the controller.
Due to timing constraints imposed to ensure integrity of the DMX signal,
a maximum of seven in-line devices are allowed between the controller
and an output with a responder attached.
The PWREP DIN P4 RDM is considered an “in-line” device. The signal
path may never include more than seven DIN splitters. Anything greater
will prevent devices further downstream from being able to respond.
WARNING: DO NOT install other RDM responders
between the controller and the PWREP DIN P4
RDM, or between the THRU connector on one DIN
device and the DMX IN on the next.
