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 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 the
markup of L and N on connector 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 ration 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.
