The RdmSplitter is an optically isolated splitter/booster for DMX and RDM networks.


RdmSplitter: DIN rail DMX/RDM splitter/booster
The RdmSplitter is an optically isolated splitter/booster for DMX and RDM networks.

Extend the DMX network
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 a DMX cable should not be longer than 300 meters.

The RdmSplitter helps tackle those inconvenient limitations. The Splitter takes a DMX signal and sends it out again on its 6 DMX output ports. 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.

Make cable runs easier
Normally DMX requires fixtures to be connected in bus-topology having one cable running via each device. The RdmSplitter allows a star-topology for efficient cable usage.

Prevent ground loops
The DMX output ports are protected through optical isolation, safe guarding the splitter and its connected equipment against power surges and dangerous ground loops.

Receive fixture feedback
The RdmSplitter supports RDM communication. RDM is the protocol that allows your fixtures to send feedback information to the lighting controller via the DMX cable.

There is also a DMX-only splitter available with RJ-45 connectors.
