The DMX splitter is available in three standard configurations: three, five, or eleven outputs from a single DMX input. An enhanced five output splitter with lightning and miswiring protection, and a universal power supply is also available (see the 125EE data sheet). Units with any number of inputs and outputs may be manufactured on a custom basis. For custom units, please contact StageSpot directly at 888-56-STAGE.

Each output is electrically isolated from the input, and from every other output, by 2500 volt optical couplers. Each output has its own line driver and associated power supply.

The DMX 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 not good practice to simply split a DMX control cable using a "wye" cable as this can cause signal corruption due to reflections. Typical uses of the splitter include splitting the control signal between stage right and stage left dimmers, running an isolated split to a string of color changers, splitting and isolating a feed to a wall outlet for temporary or rented dimmers, isolating a stack of dimmer packs from each other, etc.

The Enhanced2 Isolated Splitter [125EE] 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 125EE adds four transient absorbers on the input, two on each output, and one on the power line. To protect against miswiring, it also 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 signal. The 125EE is designed to work on any voltage between 90 and 240 volts.

NOTE: This product uses slew-rate-limited output drivers. Slew-rate-limited drivers minimize EMI and reduce reflections caused by improperly terminated cables.

    Available the following models:
  • 1 Input, 3 Outputs (model 123)
  • 1 Input, 5 Outputs (model 125)
  • 1 Input, 5 Outputs Enhanced, Front Mount Connections (model 125EE-FT)
  • 1 Input, 5 Outputs Enhanced, Wall Mount (model 125EE-WALL)
  • 1 Input, 5 Outputs Enhanced (model 125EE)
  • 1 Input, 11 Outputs (model 1211)
