Doug Fleenor Design 1211-5 Isolated Amplifier and Splitter

Description: Doug Fleenor Design 1211-5 Isolated Amplifier and Splitter - 5 pin XLR. 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 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 DMX pinouts are printed on the splitter Powder coated 1/10" aluminum chassis Gold plated Neutrik 5 pin connectors All integrated circuits are socketed Uses 2500 Volt optical couplers Forty times faster than DMX data rate "Air gap" circuit board under isolator 60 mA drive current 60 mA drive current Specs 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.
