Друкувати сторінкуThe Splitter/Amplifier provides between one and eleven DMX512 outputs from a single
DMX512 input. The outputs are electrically isolated from the input and from each other
by 2500 volt optical couplers.
All models of our Splitter/Amplifier boost the signal as well as isolate it. Input levels as
low as 0.2 volts are transmitted at full EIA-485 levels (about 4.5 volts).
The splitters allow the DMX signal to be split without the possibility of reflections from one
signal path interfering with the signal to a device on a different path. By isolating each
output, electrical noise and hazardous voltages on one output are prevented from
affecting (or damaging) devices on the input or another output.
Common uses for the Splitter/Amplifier include:
!
Boosting the signal level on long control runs (greater than 500 feet)
!
Splitting the signal to multiple dimmer locations
!
Splitting the signal between dimmers and other DMX devices (color changers, moving
lights, etc.)
!
Isolating two or three dimmer packs from each other.
Although this product was designed for the digital multiplex lighting control standard
DMX512, the units use standard EIA-485 components. They can be used to split and
isolate any single-drop uni-directional EIA-422 or EIA-485 line up to the rated data rate of
250 Kb/s.
Plug the splitter's line cord into a grounded electrical outlet. The splitter requires between
100 and 120 volts, 50 or 60 hertz. It requires less than 1/10 amp (12 Watts). It should
be grounded for maximum electrical noise isolation and safety. The earth ground is
connected only to the chassis. All circuitry is isolated from the chassis and the power
cord's ground pin.
Plug the console or other DMX source into the Splitter/Amplifier's input connector.
Connect the output(s) of the unit to the dimmers or other DMX receivers.
The splitter is normally provided with the connectors specified for DMX512:
Input = 5 pin male "XLR" style
The signals on each pin are:
1 = Common
2 = Data -
3 = Data +
4 = No Connection
5 = No Connection
The unit may also be ordered with non-standard connectors such as 3 pin "XLR" style.
Note that pin 1 is common in name only. All commons are electrically isolated from each
other.
