IMPORTANT SAFETY INFORMATION

The following general safety precautions have to be observed during all phases of
operation, service, and repair of this equipment. Failure to comply with these precautions
or with specific warnings in this manual violates safety standards of design, manufacture,
and 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
or it should not be installed or operated without a 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 marking of L and N on
the connector for correct wiring of Line and Neutral.

Battery connection

Battery for DST4 power can be connected to screw terminal on the rear side of the
device. There is no strict requirement of polarity – you can use AC or DC power with the
limitation of voltage 12-24V.

DMX connection

DMX connectors are located on both sides of the splitter board. They are separated into
two groups. 1st 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 the last in line, it should be terminated by
the termination resistor of 120ohm wired between pins 2 and 3.

The 2nd part of the splitter consists of 4-way optically isolated lines marked with letters A­D. Each line has a separate power supply, line driver and indication of signals D+, D- on
both signal lines. These LEDs are active when the splitter is retransmitting DMX signal
and there is no short circuit between data lines.

In case of a short circuit between data pins D+/D- and the CMN pin, the LED connected to
the data line will go off.

Pin 1 Common
Pin 2 Data -
Pin 3 Data +

Device in use / service:

By default, Power LED indicates the device is on main power. If the power light does not
light up, please check main power input. The unit can be supplied with AC85-264V or
AC/DC battery power. There is no polarity restriction for this port. You can use AC or DC
power with 12-24V.

When the DMX cable is connected to the device, the LEDs marked as D+ and D- go ON for
the side marked as DMX input, thru and this indicates that the DST4W-PRO is receiving
the DMX signal. Blinking frequency of these LEDs also indicates refresh rate of the DMX
signal. Fast blinking – high refresh rate, slow blinking – low refresh rate.

On the rear panel of the DST4W-PRO, you can see outputs A-D, which are retransmitting
the input to the optically isolated outputs. If any of the data LEDs is off, unplug the signal
cable corresponding to this output and check the cable for short circuit between D+ and
CMN or D- and CMD lines.
