    123-3 - Overview

    The Doug Fleenor Design Model 123 DMX splitter is available in three standard configurations: three, five, or eleven outputs from a single DMX input. An enhanced five output splitter with miswiring and lightning protection, and a universal power supply is also available (see the model 125EE data sheet). Units with any number of inputs and outputs may be manufactured on a custom basis.

    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.

    • Features:

      • Input is electrically isolated from output
      • Outputs are isolated from each other
      • Outputs are separately buffered
      • No user adjustments. Easy "fool proof" installation
      • DMX pinouts are printed on the splitter. Assists in proper control wiring
      • Powder coated 1/10" aluminum chassis. Rugged and attractive for years of service
      • Gold plated Neutrik 5 pin connectors. Assures reliable connections
      • All integrated circuits are socketed. Eases field service
      • Uses 2500 Volt optical couplers. Easily isolates line voltage failures. Usually withstands electrical storm damage
      • Forty times faster than DMX data rate. Reliable, high speed data throughput. Units can be cascaded
      • "Air gap" circuit board under isolator. Prevents arcing across circuit board
      • 60 mA drive current. Reliably drives long control cables
      • Power and input signal indicators. Simplifies system trouble shooting
       
    • Specifications:

      • Input circuit: EIA-485 receiver with 120 ohm termination resistor between +Data and -Data (Units with feed through connectors do not have internal termination)
      • Input signal: 0.2 volts minimum, 12 volts maximum
      • Output circuit: EIA-485 driver
      • Connectors: Gold plated 5 pin Neutrik D-1 Series (3 pin connectors, terminal blocks, or RJ45 optional)
      • Feed through: A non-isolated feed through connector is standard on the eleven output model and is
      • optional on the one, three, and five output models.
      • Isolation: 2500 volt optical coupler, 1500 volt split bobbin transformer
      • Power input: 100 - 120 volts, 50/60 hertz, 12 watts (208 - 240 volt optional)
