Introduction
Thank you for purchasing the Ayra OSO W-D. This practical kit, consisting of two wireless DMX 'pens' and 2
matching power adapters, is used to transmit DMX signals from a lighting controller or interface to your DMX
enabled lighting fixtures. One of the devices is the transmitting device, the other one is the receiver. This
user manual provides you with all the information you need to get the best out of the features this device has
to offer.
Read this user manual before you set up the device and familiarise yourself with the product and its
accessories. Also check the box contents to make sure the device has not been damaged and all
accessories are included as they should.
If you encounter any problems during unpacking, installation or use, contact your local dealer for more
information and help.
The OSO W-D kit can be extended with the use of one of the OSO DIS-H wireless DMX splitters. This way,
upon arrival of the wireless signals, the signal can be splitted in several isolated outputs. This gives users the
flexibility of making multiple DMX groups, without having to pull cables from and to every fixture.
The OSO W-D makes use of special technology to ensure that the wireless transmitted signal is as strong
and stable as possible. However, the reliability of the system depends on the surrounding environment,
something which can not always be controlled. It is therefore recommended to use cables to connect your
DMX devices where possible and practical, as technically this is always a more stable and reliable solution.
For situations where the use of cables is impossible, dangerous or difficult, the OSO W-D is an useful
problem-solver.
Please note before use:
The OSO W-D works on the 2.4 GHz frequency. This is a global free to use frequency, also used by
equipment such as wireless microphones, Bluetooth speakers, smartphones, tablet computers, microwaves,
WiFi-routers and so on. When used for applications such as large festivals, the OSO W-D will be surrounded
with a lot of devices who make use of the same frequencies.
Thankfully, the OSO W-D is equipped with modern electronics, preventing interference as much as possible.
As the surroundings with every use of this product vary, 100% stable operation of this product can not be
guaranteed in all circumstances.

Setting up and using the OSO W-D
OSO W-D mounting
Upon arrival and unpacking, the OSO W-D requires a little bit of assembly before it can be used.
The 2 seperate antennas which are included, can be mounted on the corresponding connector. Twist the
connector clockwise in place until you feel it has been tightened.
The antenna of the OSO W-D can be angled, which can be easier for use in some settings. Please note that
the antennas should point at the same direction (either up or down) for the best signal transfer.
Powering the unit
Connect the power adapter (both are identical) to either the transmitter or receiver and plug the adapter into
a suitable wall outlet. Once power is detected, the units will start up.
The units will both blink when powered up to determine their status.
Common status:
Transmitter status:
- red blinking: sending wireless DMX signal
- red full on: No DMX signal
Receiver status:
- green blinking: receiving wireless DMX signal
- green full on: no wireless signal
The transmitter can be plugged directly into a lighting console or DMX computer interface. The receiver can
be plugged into one of your DMX lighting fixtures. It’s also possible to connect the transmitter somewhere
else in the signal chain, in case you wish to transfer the signal further from a lighting fixture near your setup.
It may be practical to use a standard XLR cable between the wireless DMX transmitter/receiver and the
console or lights to be able to position the devices better. This has no influence on the operation of the
devices.
To ensure a connection between the transmitter and receiver, make sure both devices are set to the same
ID. You can do this by pressing the red button on the unit. When pressing, the unit will go to the next ID and
show the corresponding colour. There are 7 ID’s, each coloured differently by an RGB LED. Once the
desired ID shows up, the device will go back to showing the current status.
Once a connection has been established, the transmitter will blink red, the receiver will blink green. DMX
data can now be transferred from the lighting console to the DMX lighting fixtures.
Stability and reliability when in use
Please note that the OSO W-D works on the global free to use 2.4 GHz band. The system makes use of the
7 ID’s to ensure that up to 7 systems can work together.
However, please be aware that the 2.4 GHz band is also used by lots of other equipment, such as:
- laptops
- smartphones
- Bluetooth enabled devices
- WiFi enabled devices (also routers)
- tablet computers
- microwaves
To prevent signal loss, the OSO W-D continuously seeks for stable signals in 126 different channels in the
2.4 GHz band it operates in.

Next to the various other types of devices working on the same frequency, other influences may have effect
on the signal stability and reliability. Such as:
- walls blocking or decreasing signal strength
- objects or humans blocking or decreasing signal strength
- weather influences on long distance
To prevent this from happening, make sure that the transmitter and receiver are able to ‘see’ each other
properly. This means that when pulling an imaginary straight line or wire from the transmitter antenna to the
receiver antenna, no objects, humans or walls should be able to block this line.
In case your controller or DMX fixture blocks the signal physically and the system is used on a large
distance, an extra XLR cable can be pulled in such a way that the transmitter and receiver establish a better
connection. As the weight of the transmitter and receiver is very limited, these could be mounted to a lighting
stand, truss system or microphone stand with cable velcro strips, zip ties or similar.
In the most ideal situation, the transmitter and receiver could be placed up to 300 meters apart from each
other and still send and receive DMX signals. But in practice, there will always be negative influences which
will decrease signal strength and stability. Some will alter the reliability more than others.
Therefore it is important to think about your setup before setting up the wireless DMX system. When the
application is critical, the distance is quite long, the signal needs to pass lots of objects or audience and lots
of other 2.4 GHz equipment is present between the transmitter and receiver, you might need to reconsider if
this is the best solution.
Even though the best technologies have been used in order to create the OSO W-D, nothing is more reliable
than a cable because it either works or doesn’t. Therefore the OSO W-D is the best solution for applications
where you wish to pull a cable, but where this is not possible because of dangerous situations or impossible
positioning.
As every situation and application of every user is different, Ayra can not ensure problem free operation,
because lots of unpredictable influences may alter the reliability.
Using OSO W-D with DMX controllers
The OSO W-D works with nearly all kinds of DMX controllers, lighting consoles and even USB to DMX
interfaces. It also works with products sending less channels out than the standard 512. This means that also
192-channel, 12-channel or even 6-channel DMX controllers can be used together with the OSO W-D.
Spare parts
This unit has no user-serviceable parts inside. When any damage to components occur, contact your local
dealer or a specialised technician in order to repair or replace the fixture.
Cleaning:
Clean the housing of the fixture frequently with a damp cloth, to remove dust and/or dirt. The machine must
be cooled down, turned off and removed from any power source when doing so.
WARNING: Always disconnect the fixture from your wall outlet or other power supply and let the fixture dry
before reconnecting it. This prevents possible electric shocks.
Check-up
To prevent dangerous situations, make sure your fixture is in optimal condition before using it. Check your
fixture frequently by using the following check list:
- All screws must be mounted tightly.
- Check all screws and metal parts for corrosion. No visible corrosion should be present.
- The exterior of your fixture must be in optimal condition. Check your fixture for dents, cracks or missing
parts.
- The area in which the device will be used or mounted must be in optimal condition. Check this installation
spot for corrosion, cracks, dents and strength.
- Electrical components (connectors and cables) must be in optimal condition. No form of damage (cuts,
exposed wire cores or any other irregularities) should be visible.

- the transmitter and receiver are placed in line without objects or humans blocking the shortest
possible signal (drawing an imaginary straight line from the transmitter to the receiver)
- some signal disturbing sources are present nearby, such as phones from your audience,
microphone systems on the same frequency and tablet computers or laptops.
Increasing the distance between transmitter and receiver may still result in a proper working system,
but the chance of signal disturbance will increase and is therefore not recommended for critical
applications where signal drops can not take place. (For example in theatre environments)
Ayra chooses to inform the user about the theoretical max. operating distance as a reference, but
please be aware that similar ideal circumstances will usually never be present during actual and
expected use of the product without signal drops. The recommended operating distance provides the
most optimal signal while still being useful and reliable.
