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
