The D-Split is an optically-isolated DMX splitter and repeater for DMX512. It allows one DMX input (either 3-pin or 5-pin) to be replicated on to 4 isolated output ports, each of which can be used to create a new chain of up to 32 DMX fixtures. Instead of having to make all fixtures fit within a single daisy chain, each of the four outputs from the D-Split can be the start of its own chain. Multiple D-Splits can be linked together for even greater flexibility.
