NEW Doug Fleenor DMX512 Isolated Opto Splitter / Amplifier 1 In, 3 Out

The Doug Fleenor DMX512 Isolated Opto Splitter / Amplifier takes a single DMX512 control input and delivers three electrically isolated DMX outputs, making it ideal for distributing one universe to multiple runs while protecting your console and fixtures from ground loops, noise, and wiring faults.

Flexible DMX Distribution for Real-World Rigs

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. Units with any number of inputs and outputs may be manufactured on a custom basis.

True Output-to-Output Isolation

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, helping maintain a clean EIA-485/DMX signal across long cable runs and keeping problems on one branch from affecting the rest of the system.

Star Wiring Without Signal Corruption

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. If you would like assistance in your application, please give us a call.
