The Flexible Optical Splitter
The Flexible Optical Splitter is a custom DMX distribution amplifier at a stock unit price.
Multiple output optically isolated DMX512 distribution amplifiers or "Opto-splitters" have become necessary in many DMX512 systems. They provide two needed features. First, they allow wiring DMX512 in a star topology with cables radiating from the console to receivers placed throughout the facility; each cable leaving a splitter is a separate transmission line. Second, they provide total electrical ground isolation between different branches of the star. This greatly decreases problems with ground loops.
The Flexible Optical Splitter has several features
that are common to any good fully optically isolated splitter.
What sets the Flexible Optical
Splitter apart is
its flexible architecture. We package the FOS in a
3.5" (2U) 19" rackable case. The case houses a
universal power supply that will operate from
100 VAC to 250 VAC mains without any
switching or restrapping. The case provides
mounting bays for input and output modules.

The breakdown voltage of the FOS's isolation barrier is greater than 500 volts. Nevertheless, the FOS is not intended to provide AC mains voltage isolation. All lines entering and leaving the FOS MUST be low voltage control lines. Isolation is only provided to prevent ground loops and other data transmission problems. |
One way to see the flexibility of the FOS is to examine some models that we have built for customers. These examples are just a few of the models that we can build. If you have a special requirement please let us know; we can probably provide a solution. Looking at the data sheet for our DMX-NET products may also be useful. Goddard Design constructs the FOS and DMX-NET out of the same components and they share many common features. In some application a combination of the two products produces the most flexible DMX512 distribution system.
8 Output Stage Box with Redundant Inputs
Application: This model provides on-stage distribution
of DMX using a 'star' topology. The special feature of this model is
that
it provides two DMX512 inputs, a primary and a secondary. If the signal
is lost on the primary input, the splitter automatically
switches to secondary DMX input. The two inputs may come from either
redundant cables or even from redundant consoles
Components Required: Standard case, 8 output modules,
2 input modules.
Other Options: may be ordered with rack ears, plain
end plates or handle end plates
Price: $1650.00
6 Output Splitter with Loop through Output
Application: This model is a standard 6-way splitter
with an unbuffered loop-through connector. If line termination is
wanted, a
termination slug should be installed in the loop-through output. Components
Required: Standard case, 6 output modules, 1
input modules, 1 loop-through connector.
Price: $1225.00
4 Universes by 2 Output Splitter
Application: A customer ordered this model to provide
buffering for the house snake coming from a large configurable moving
light console. Note: This model was built without input modules.
Other Options: Units may be ordered either terminated
or unterminated. If unterminated, this model presents approximately 2
load units to the DMX line.
Components Required: Standard case, 8 output modules,
4 input connectors.
Price: $1450.00
2 Universes by 3 Output Splitter
Application: A system integrator ordered this model to
provide buffering for a DMX512 patch rack. They ordered this model
using our input modules. The LED on the input module provides positive
indication that dynamic data is present. These units
terminate the DMX line. All connectors are mounted in the front panel.
Components Required: Standard case, 6 output modules,
2 input modules.
Price: $1350.00
4 Zone Distribution Box with a Test Input for Each Zone
Application: This model provides unique features.
Having different types of DMX devices driven by different cables is
common.
The under stage dimmer room is seldom fed in line with the on stage
color scrollers and moving lights. FOH DMX equipment is
also a natural zone. Having a technician testing one zone or type of
equipment is often desirable, say the color scrollers, while
leaving the rest of the system connected to the main console. Our zoned
distribution boxes do this easily. This model has 1 main
DMX input and 4 isolated outputs. Mounted next to each of the isolated
outputs is a test input. Connecting a DMX signal to a
test input takes control of that zone. The other three zones remain
connected to the main DMX input. The main input has jumper
selectable termination. Test inputs are always terminated.
Components Required: Standard case, 4 output modules,
4 input modules, 4 switch modules, 1 input connector.
Other Options: May be ordered with a loop-through
connector.
Price: $1975.00
