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 A 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. 1
st
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 .
The 2
nd
part of the splitter consists of 4-way optically isolated lines marked with letters A-
D. 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.

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.

DMX-only operation
For DMX operation, turn off the W-DMX module by
holding the MODE button. Both W-DMX and MODE
buttons should be RED.
Connect the DMX cable to DMX-IN connector and
use the DST4W-PRO as a standard DMX isolated
splitter one to four.
Once the DMX signal is active, the LEDs marked as
D+ and D- will go ON for both input module and
output modules A-D.
How to change W-DMX Receiver to Transmitter and vice versa:
Turn off the splitter by unplugging the power cable. Hold the W-DMX button and plug in
the power cable. The unit has now changed its state. Without holding the W-DMX button,
the unit will stay in the same mode as it was before.
W-DMX receiver: Bargraph shows signal or is off, if the unit is not linked to any
transmitter.
W-DMX transmitter: Bargraph’s green LEDs are lighting one by one showing that the unit
is transmitting DMX signal over the air.
W-DMX/DMX operation
For the W-DMX/DMX operation, turn the W-DMX module on by holding the MODE button.
Both W-DMX and MODE buttons should light GREEN.
Connect the DMX cable to DMX in/thru connector and use the DST4W-PRO as a standard
DMX isolated transmitter. For receiver mode, use outputs A—D.
Once the DMX signal is active, the LEDs marked as D+ and D- will go on for both input
module and output modules A-D.

W-DMX Receiver/Splitter
You can use the DST4W-PRO as a Receiver with the Splitter output.
There is an automatic back-up of the W-DMX line using the cable connection. If the W-DMX
is linked to the transmitter and the signal quality is poor, the W-DMX active LED goes off
and the splitter will retransmit signal from cable in/thru port. In normal state, when the W-
DMX signal quality is good, the W-DMX active LED is on.
The W-DMX button has only one function – logging off from the linked transmitter.
W-DMX LED signalization in the Receiver mode:
Receiver Mode unlinked
MODE LED is GREEN and the receiver W-DMX LED is RED. The bargraph does not show
the signal strength.
Receiver Mode linked
MODE LED is GREEN and the receiver W-DMX LED is RED or GREEN according to the DMX
connection on the Transmitter’s side. The bargraph shows the signal strength.

W-DMX Transmitter/splitter
You can use the DST4W-PRO in the Transmitter and DMX splitter mode at the same time.
The DMX signal from input/thru is sent out via Wireless DMX to all other linked W-DMX
devices.
Signal bargraph LEDs are blinking in a row to indicate that the module is in the
Transmitter mode.
W-DMX button has two functions:
Short press: Linking unlinked Receivers,
Long press: Unlinking all linked Receivers
W-DMX LED signalization in Transmitter mode:
Transmitter without DMX
MODE LED is GREEN and the W-DMX LED is RED or GREEN according to the status of the
DMX connected to the in/thru port.
To add an unlinked Receiver, press the W-DMX button for a second. The unlinked
Receiver will start to blink fast.
After a successful pairing, the W-DMX buttons on both units will blink slowly showing the
same status of the DMX connected to the Transmitter.
Transmitter with DMX
DMX is connected to the Transmitter and transmitting the W-DMX signal. W-DMX LEDs on
both Receiver and Transmitter are GREEN.
Bargraph is active and shows the W-DMX signal strength and the DMX status on the
Receiver.
