The widespread data protocol for lighting equipment is DMX-512. It is a very successful protocol with, however, a few limitations. The maximum number of attached devices is limited to 32 and they all have to be connected in bus-topology having one cable running via each device.
Furthermore, a DMX cable should not be longer than 300 meters.
The RdmSplitter from Visual Productions helps tackle those inconvenient limitations. The splitter takes a DMX signal and sends it out again on its 6 DMX output ports allowing a star-topology for efficient cable usage. Each output port is capable of driving 32 more devices. The splitter can also function as a signal booster as each port supports another 300 meter long connection.
The RdmSplitter features RDM compatibility. The RDM protocol provides two-way communication over a DMX infrastructure. It enables automatic addressing and allows fixtures to provide status information back to the lighting controller
