The Martin Splitters help to rectify disruptions in the DMX signal caused by bad cables or bad connections by splitting the DMX or DMX/RDM data link into five separate branches while boosting the weak DMX signal to its original output level before it becomes too low to be read by DMX devices.
Through fully individual isolated input and five outputs, the Martin Splitters will protect any DMX controller and DMX fixture against voltage surge on the data line. Ground loops are common in complex lighting setups and such problems can create errors in the DMX data. The Martin Splitters will help to prevent such situations.
Another common issue with DMX communication is reflection caused by long lines, too many connections, or too many devices on the same line, etc. The Martin Splitters prevent such reflection by dividing the load over several outputs, therefore making shorter lines with less connections and devices. If an error is detected on the DMX line, the Splitter will illuminate an error LED.
