The new MDR-DIN splitter continues a long history of innovation at LSC. Based on the successful range of MDR splitters, the new MDR-DIN is a mounted product providing 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.

Remote Device Management (RDM) is an extension to the existing DMX standard and allows controllers to configure and, in some cases, monitor DMX-based products. The MDR-DIN handles the management of RDM signals across its four outputs. 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. Houston X is due for staged release throughout 2019.  

For installations that require a 19" rackmount or portable splitter, the MDR range offers many benefits. Click here for more information
