operation, service, and the repair of this equipment. Failure to comply with these
precautions or with specific warnings in this manual violates safety standards of design,
manufacture, and the intended use of this equipment.
Do not operate in an explosive atmosphere!
Do not operate this equipment in the presence of flammable gases or fumes. Operation of
any electrical instrument in such an environment constitutes a definite safety hazard.
Device should never be placed near or over a heat register or other source of heated air
and it should not be installed or operated without proper ventilation.
Mains 85-265V connection
AC power is connected to the splitter via Neutrik PowerCon blue connector. Standard
supply is UNISCHUKO lead with Neutrik PowerCon. Always respect marking of L and N on
connector for correct wiring of Line and Neutral.
DMX connection
DMX connectors are located on the front panel of the splitter board. These are separated
into two groups. First group is wired in ratio 1:1 and marked as DMX input and DMX thru
and is located on the left side of the splitter. This line is not optically isolated and when
the device is last in line, it must be terminated by the termination button near the DMX
thru connector.
The other part of splitter consists of 8-way optically isolated lines marked with numbers 1-
8. Each line has a separate power supply, line driver and the indication of signals D+ and
D- on both signal lines. These LEDs are active when the splitter is retransmitting the DMX
signal and there is no short circuit between data lines.
In case of short circuit between data pins D+/D- and the CMN pin, the LED connected to
the data line will be off.
