IMPORTANT SAFETY INFORMATION
The following general safety precautions have to be observed during all phases of
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 be never 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 AC 100-255V connection
AC power is connected to the splitter full range power supply with worldwide use via 1.8m
long UniSchuko cable connected to the splitter via PG. Always respect the markup of L
and N on connectors for correct wiring of Line and Neutral.
DMX connection
DMX connectors are located on both sides of the splitter board. These are separated to
two groups. First group is wired in ratio 1:1 and marked as DMX input and DMX thru. This
line is not optically isolated and when the device is last in line, it should be terminated by
the termination resistor of 120ohm wired between pins 2 and 3 of the DMX thru
connector.
The other group consists of 4-way optically isolated lines marked with letters A-D. Each
line has a separate power supply, line driver and the indication of signals D+, D- on both
signal lines. These LEDs are active when splitter is retransmitting 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 is off.
