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 AC85-265V connection
AC power is connected to the splitter via Neutri PowerCon blue connector.
Standard supply is UniSchu o lead with Neutri PowerCon. Always respect the
mar ing of L and N on connector for correct wiring of Line and Neutral.
DMX connection
DMX connectors are located on both sides of splitter board. These are separated
to two groups. Frist group is wired in ratio 1:1 and mar ed as DMX input and DMX
thru. This line is not optically isolated and when device is the 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 side of the splitter consists of 4-way optically isolated lines mar ed
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 data line will be off.

Device in use service:
By default, Power LED indicates the device is on main power. When the power
light is off please chec the main power input. When this does not solve the
problem please call the assistance first and then open DST4H and chec fuses
on the main board.
When the DMX cable is connected to the device, LEDs mar ed as D+ and D- go
ON for the side mar ed as DMX input, thru and this indicates that DST4H is
receiving the DMX signal. Speed of light on these LEDs also indicates the
refresh rate of DMX signal. Fast blin ing – high refresh rate, slow blin ing – slow
refresh rate.
On the rear panel of DST4H, there are outputs A-D, which are retransmitting the
input to the optically isolated outputs. If any of data LEDs is off, unplug the
signal cable corresponding to this output and chec the cable for short circuit
between D+ and CMN or D- and CMD lines.
