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 never be placed near or over a heat
register or other source of heated air or it should not be installed or operated
without proper ventilation.
Mains AC 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 ing of L and N on the connector for correct wiring of Line and Neutral.
Battery connection
Battery for DST4 can be connected to screw terminal on the rear side of the
device. There is no strict requirement of polarity – AC or DC power with the
limitation of voltage 12-24V can be used.
MX connection
DMX connectors are located on both sides of the splitter board. They are
separated into two groups. First group is wired in ratio 1:1 and mar ed 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 other part 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 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.

evice 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.
The unit can be supplied with AC85-264V or AC/DC battery power. There is no
polarity restriction for this port. AC or DC power with 12-24V can be used.
When the DMX cable is connected to the device, the LEDs mar ed as D+ and D-
go on for the side mar ed as DMX input, thru and this indicates that the DST4W-
PRO is receiving the DMX signal. Blin ing frequency of these LEDs also indicates
refresh rate of the DMX signal. Fast blin ing – high refresh rate, slow blin ing –
low refresh rate.
On the rear panel of the DST4W-PRO, there are 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 chec the cable
for short circuit between D+ and CMN or D- and CMD lines.

MX-only operation
For the DMX operation, turn off the W-
DMX module by holding the MODE button.
Both W-DMX and MODE buttons light in
red color.
Connect the DMX cable to the DMX-IN
connector and use the DST4W-PRO as a
standard DMX one-to-four isolated
splitter.
Once the DMX signal is active, the LEDs
mar ed as D+ and D- will go on for both input module and output modules A-D.
Changing W- MX 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- MX receiver: Bargraph shows the signal strength or is off, if the unit is not
lin ed to any transmitter.
W- MX transmitter: Bargraph’s green LEDs are lighting one by one showing
that the unit is transmitting DMX signal over the air.
W- MX/ MX 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 in green color.
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 mar ed as D+ and D- will go on for both
input module and output modules A-D.

W- MX Receiver / Splitter
You can use the DST4W-PRO as a Receiver with the Splitter output.
There is an automatic bac -up of the W-DMX line using the cable connection. If
the W-DMX is lin ed 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 lin ed
transmitter.
W- MX LE 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- MX Transmitter / Splitter
The DST4W-PRO can be used 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 lin ed W-DMX devices.
Signal bargraph LEDs are blin ing in a row to indicate that the module is in the
Transmitter mode.
W-DMX button has two functions:
Short press: Lin ing of unlin ed Receivers
Long press: Unlin ing from all lin ed Receivers
W- MX LE signalization in Transmitter mode:
Transmitter without MX
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 unlin ed Receiver, press the W-DMX button for a second. The
unlin ed Receiver will start blin ing quic ly.
After a successful pairing, the W-DMX buttons on both units will blin slowly
showing the same status of the DMX connected to the Transmitter.
Transmitter with MX
DMX is connected to the Transmitter and is transmitting the W-DMX signal. W-
DMX LEDs on both Receiver and Transmitter light in green color.
Bargraph is active and shows the W-DMX signal strength and the DMX status
on the Receiver.
