Enhanced2 DMX512 Isolated Splitter PDF Link

The Enhanced2 Isolated Splitter includes all the features of our standard models with added protection to meet the needs of harsh operating conditions. As with our standard splitters, all outputs are isolated from the input and from the other outputs by optical couplers. Every output has its own power supply and line driver. For protection against electrical storms, the Enhanced Splitter adds four transient absorbers on the input, two on each output, and one on the power line. To protect against miswiring, the Enhanced Splitter has self resetting fuses on the DMX512 input and outputs that protect the Splitter against damaging voltages up to 120 volts. Indicators on each output display power and termination status. Indicators on the input display signal present and valid DMX. The Enhanced Splitter is designed to work on any voltage between 90 and 240 volts.

The Enhanced Splitter allows connection of DMX receivers (dimmers, color changers, moving lights, etc.) in a star configuration as opposed to a daisy chain configuration. In a star configuration, each control cable is run to a central point, in this case the splitter. In a daisy chain configuration all the devices are connected on one control cable, the output of one feeding the input of the next. It is good practice to limit the number of receivers on a DMX512 output to 32 devices. The Enhanced Splitter gives you five outputs from one input allowing up to 160 receivers (32 per output).
