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 85-265V connection
AC power is connected to the splitter via Neutri PowerCon blue connector.
Standard supply is UNISCHUKO lead with Neutri PowerCon. Always respect the
mar up 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 ration 1:1 and mar ed 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 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 the data line is off.

Device in use / service:
By default, Power LED indicates the device is on main power. When the Power
LED is off, chec the main power input. When this does not solve the problem,
please call service first and then open DST4 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 DST4 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 DST4, there are outputs A-D, which are retransmitting the
input to the optically isolated outputs. If there 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.
If case of any problems, do not hesitate to contact us via email at
[email protected] or call us at [phone]. Don’t worry; we will fix your
problems for sure.
