1 Introduction
1.1 Overview
The MDR-DIN splitter is based on the successful range of MDR splitters. It is housed in a 5-
module wide DIN plastic enclosure designed to mount onto a standard TS-35 DIN rail as used
extensively in the electrical industry to mount circuit breakers and industrial control equipment.
The MDR-DIN splitter provides four individual outputs from one DMX/RDM input. Each output is
completely electrically isolated from the input and all other outputs, ensuring that voltage
differences and noise will not compromise your installation.
The MDR-DIN handles the management of RDM (Remote Device Management) signals across
its four outputs. RDM is an extension to the existing DMX standard and allows controllers to
configure and monitor DMX based products. Unique to the MDR-DIN is the ability to individually
disable RDM on any of its outputs using the front-panel switches. While many devices now offer
RDM compatibility, there are still products available that do not perform correctly with RDM,
causing the DMX network to flicker or jam when RDM signals are present. The MDR-DIN
provides the ability to isolate these devices to one output by disabling the RDM, ensuring RDM
can be used successfully on the remaining ports.
With LSC’s companion product, Houston-X, the state of the RDM enabled switches can be
monitored remotely and a list of connected RDM devices can be reported including which output
each device is connected to. Houston X also allows MDR-DIN software to be updated via RDM,
so once it’s installed there’s no need to access the product again.
1.2 Models
Two models are available. Both models use push fit terminals for power connections.
• MDRD/T. Push-fit terminals for DMX INPUT and 4 DMX outputs
• MDRD/J. RJ45 sockets for 2 DMX IN/THRU and 4 DMX outputs for installations where
Cat-5 style cable is used for DMX512 reticulation
1.3 Features
• Four DMX/RDM outputs
• Each output is electrically isolated from the input and all other outputs
• RDM capability of each output port can be disabled for situations where legacy
equipment is not compatible with RDM signals
• Splitter is discoverable by RDM
• Outputs can be labelled via RDM
• LSC’s Houston-X monitoring and configuration system can display your network
topography
• Each output circuit can be labelled via RDM for greater clarity in more complex
networks
• LEDs for power, DMX and RDM activity
• Easy software update via RDM
• Conforms to the latest DMX/RDM standards
• CE (European) and RCM (Australian) approved
• Full two-year factory warranty
• Designed and manufactured in Australia by LSC – an Australian-owned company with
over 30 years' experience in developing world-first DMX512 products

2 Installation
2.1 Installation
1. Mount the unit on a standard TS-35 DINrail (IEC/EN 60715). The unit is 5 modules wide.
2. Connect a suitable power source to the 9-24V DC push-fit terminals observing the correct
polarity. A minimum of 5W of power is required.
3. Connect the DMX512 cables
MDRD/J
RJ45 Connectors
MDRD/T
Push-Fit Terminals
Plug the DMX source cable into either DMX
IN/THRU connector
Connect the DMX source cable into the DMX
INPUT terminals
If this MDR-DIN splitter is the last device at
the end of the DMX512 input cable, connect
a 120 ohm resistor to the other DMX
IN/THRU connector. See section 2.4 for the
pin-outs. If the MDR splitter is not the last
device on the line, the other DMX IN/THRU
connector can be used to connect the DMX
to other equipment
If this MDR-DIN splitter is the last device at
the end of the DMX512 input cable, connect
a 120 ohm resistor across the DMX INPUT
terminals. If the MDR splitter is not the last
device on the line, the same DMX INPUT
terminals can be used to connect the DMX
to other equipment in parallel.
Connect the DMX512 output cable(s) to the
DMX512 output connector(s).
Connect the DMX512 output cable(s) to the
DMX512 output terminals.
2.2 DMX Cables
Only use specific DMX data cable. The data cable must conform to the EIA485 cable
requirements by providing the following specifications:
• Low capacitance
• One or more twisted pairs
• Foil and braid shielded
• Impedance of 85-150 ohms, nominally 120 ohms
• 22AWG gauge for continuous lengths over 300 metres
Cat 5 UTP (Unshielded Twisted Pair) and STP (Shielded Twisted Pair) cable is acceptable. If
you want to make your own cables, LSC recommends using Beldon 9842 (or equivalent). Never
use audio cable.
The end of the DMX line must be terminated (120 Ω) to prevent the signal reflecting back up the
line and causing possible errors.

2.3 Push-Fit Terminals
The following cables are suitable for use with the push-fit terminals:
• 2.5mm² stranded wire
• 4.0mm² solid wire
Stripping length is 8mm. Insert a small screwdriver into the slot adjacent to the cable hole. This
releases the spring inside the connector. Insert the cable into the round hole then remove the
screwdriver.
Solid wires or wires fitted with ferrules can often be pushed directly into the connector without
the use of the screwdriver. When connecting multiple cables to a single terminal the wires must
be twisted together to ensure a good connection to both legs. Non-insulated bootlace ferrules
can also be used for stranded cables. Ferrules are not recommended for solid cables. Insulated
bootlace ferrules can also be used allowing stranded cables to be easily inserted without the
need of a tool to actuate the spring release.
The maximum ferrule outer diameter is 4mm.

2.5 Operation
• The Power LED is lit when power is present and flashes when an RDM Identify request is
received
• The DMX LED flashes when DMX data is present
• The RDM data LED flashes when RDM data is present
2.6 RDM Enable
RDM allows RDM-based controllers and devices to communicate with each other in bidirectional
mode over the DMX cable, interleaved with the DMX512-A signal. Some older DMX-controlled
equipment is not compatible with RDM data and could flash or flicker when RDM data is present.
To overcome this problem, each individual output port can have the RDM data turned off via the
front-panel switches.
2.7 DMX Explained
DMX512-A is the industry standard for the transmission of digital control signals between lighting
equipment. It utilises just a single pair of wires on which is transmitted the level information for
the control of up to 512 DMX slots (addresses or channels). The information for each slot is sent
sequentially. The level of slot 1 is transmitted, then the level of slot 2, then 3, etc., up to a
RDM Enable
switches

maximum of 512 slots. This stream of data containing the levels for all 512 DMX slots is repeated
a minimum (generally) of 44 times per second. This provides sufficient updates of channel
information for smooth fade transitions. DMX allows a controller to communicate with a device.
It does not allow the device to communicate with the controller.
