Introduction
Thank you for purchasing the Ayra OSO DIS-H DMX splitter. This practical device orks together ith the
OSO W-D ireless DMX kit, and not only receives, but also splits the received DMX signal into t o, four or
even eight separate outputs! This user manual provides you ith 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 ith the product and its
accessories. Also check the box contents to make sure the device has not been damaged and that no
accessories are missing.
If you encounter any problems during unpacking, installation or use, contact your local dealer for assistance.
The products in the OSO DIS-H series ork together ith the OSO W-D setup. This ay, upon arrival of the
ireless signals, the signal can be split into several isolated outputs. This gives users the flexibility to make
multiple DMX groups ithout having to route cables to and from every fixture. The OSO DIS-H devices also
have a ired XLR input, so they can also function as regular ired DMX-splitters.
The OSO DIS-H makes use of special technology to ensure that the ireless transmitted signal is as strong
and stable as possible. Ho ever, the reliability of the system depends on the surrounding environment—
something hich can not al ays be controlled. It is therefore recommended to use cables to connect your
DMX devices here possible and practical, as technically this is al ays a more stable and reliable solution.
For situations here the use of cables is impossible, dangerous or difficult, the OSO DIS-H is a useful
problem-solver hen combined ith the OSO W-D.
lease note before use:
The DIS-H DMX splitters ork on the 2.4 GHz frequency. This is a global free-to-use frequency, also used by
equipment such as ireless microphones, Bluetooth speakers, smartphones, tablet computers, micro aves,
WiFi-routers and so on. When used for applications such as large festivals, the OSO W-D ill be surrounded
by a lot of devices that make use of the same frequencies.
Thankfully, the OSO W-D is equipped ith modern electronics that ork to prevent interference as much as
possible. As your surroundings vary ith every use of this product, e cannot guarantee a 100% stable
operation of this product in all circumstances.

Setting up and using the OSO DIS-H
OSO DIS-H antenna
Please unpack the unit and all accessories before mounting the included antenna. Mount the antenna on the
antenna connector by turning it clock ise. The antenna can be bent for better positioning once it has been
mounted.
owering the unit
Connect the po er cable to the po er input of the device plug it into a suitable all outlet. Once po er is
detected, the unit ill turn on.
The user can choose to use the DIS-H in ired or ireless mode. When in ireless mode, the ireless
section ill be active and sho the current status on the LED indicator. When in ired mode, the device ill
use the ired DMX input as a source.
Using the ired connection
Connect a 3-pin DMX cable from your lighting console to your DMX splitter. This ay, the incoming signal ill
be split over the several outputs, providing a strong and isolated signal for each output.
Please note, the OSO 4DIS-H and 8DIS-H have an extra output next to the DMX input; this is just a link
output, directly connected to the input.
Using the ireless connection
If there is a signal present from the OSO W-D transmitter, the units ill both blink to determine their status.
Common status:
Transmitter status:
- red blinking: sending ireless DMX signal
- red full on: no DMX signal
Receiver status:
- green blinking: receiving ireless DMX signal
- green full on: no ireless 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 some here
else in the signal chain, in case you ish to transfer the signal further from a lighting fixture near your setup.
It may be practical to use a standard XLR cable bet een the ireless DMX transmitter/receiver and the
console or lights, in order to to position the devices better. This has no influence on the operation of the
devices.
To ensure a connection bet een 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 you press the button, the unit ill go to the
next ID and sho the corresponding colour. There are 7 IDs, each ith a different coloured RGB LED. Once
the desired ID sho s up, the device ill go back to sho ing the current status.
Once a connection has been established, the transmitter ill blink red and the receiver ill blink green. DMX
data can no be transferred from the lighting console to the DMX lighting fixtures.
Stability and reliability when in use
Please note that the OSO DIS-H orks on the global free to use 2.4 GHz band. The system makes use of
the 7 IDs to ensure that up to 7 systems can ork together.
Ho ever, please be a are that the 2.4 GHz band is also used by lots of other equipment, such as:
- laptops
- smartphones
The information and illustrations shown in this user manual are subject to change without notice.
User manual version: 2.0 Creation date + author initials: 27-01-2016 RV Revision date + author initials: 23-07-2016

- Bluetooth enabled devices
- WiFi enabled devices (also routers)
- tablet computers
- micro aves
To prevent signal loss, the OSO DIS-H continuously searches for stable signals among the 126 different
channels in the 2.4 GHz band in hich it operates.
Along ith the various other types of devices orking on the same frequency, other influences may have an
effect on the signal stability and reliability. Such influences may include::
- alls blocking or decreasing signal strength
- objects or people blocking or decreasing signal strength
- eather 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 hen dra ing an imaginary straight line or ire from the transmitter antenna to the
receiver antenna, no objects, people or alls should be able to block this line.
In case your controller or DMX fixture blocks the signal physically and the system spans a large distance, an
extra XLR cable can be pulled in such a ay that the transmitter and receiver establish a better connection.
The DIS-H fixtures are equipped ith a hanging bracket, making them suitable for hanging the installation
from a beam, ceiling, truss or lighting stand hen making use of proper hard are.
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 ill al ays be negative influences that
ill decrease signal strength and stability. Some ill alter the reliability more than others.
Therefore it is important to think about your setup before setting up the ireless DMX system. If the
application is critical, the distance is quite far, the signal needs to pass throughmany objects or an audience,
or if a lot of other 2.4 GHz equipment is present bet een the transmitter and receiver, you might need to
reconsider hether this is the best solution.
Even though the best technologies have been used in the creation of the OSO W-D, nothing is more reliable
than a cable, because it either orks or it doesn’t. Therefore, the OSO W-D is the best solution for
applications here you ish to use a cable, but here this is not possible because of dangerous situations or
impossible positioning.
As every user has a different situation and application, Ayra cannot ensure problem-free operation, because
any number of unpredictable influences could alter the reliability.
Using OSO DIS-H with DMX controllers
The OSO W-D and DIS-H splitters ork ith nearly every kind of DMX controller, lighting console and USB
and DMX interface. It also orks ith products sending out fe er channels than the standard 512. This
means that 192-channel, 12-channel and even 6-channel DMX controllers can be used together ith the
OSO W-D and DIS-H splitters.
Spare parts
This unit does not contain any user-serviceable parts. In the event that a component is damaged, , please
contact your local dealer or a specialised technician to repair or replace the fixture.
Cleaning:
Clean the housing of the fixture frequently ith a damp cloth to remove dust and/or dirt. The machine must
be cooled do n, turned off and removed from any po er source doing so.
WARNING: Al ays disconnect the fixture from your all outlet or other po er 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 follo ing check list:
- All scre s must be mounted tightly.
- Check all scre s 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 hich the device ill 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 ire cores or any other irregularities) should be visible.
If any visual or mechanical damage is detected, contact your local dealer or a specialised technician. Do not
use a damaged or failing fixture.
Compatibility with wireless DMX
OSO DIS-H ireless DMX-splitters are only compatible ith the OSO W-D ireless DMX system. Therefore
this system must first be purchased to be able to use the ireless function of this device.
DIS-H DMX splitters do not ork ith DMX transmitters from other brands.
The ired operating mode can be used ithout a DMX transmitter and only requires a physical cable,
connected bet een the lighting console, controller or interface and the DMX splitter. Ensure that the
operating mode s itch is set to ired hen using the ired mode.

*The recommended max. operating distance is an estimated situation here normal and reliable
operation of the system takes place and the follo ing realistic conditions apply:
- the transmitter and receiver are placed in line ithout objects or people blocking the shortest
possible signal (dra ing 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, tablet computers or laptops.
Increasing the distance bet een transmitter and receiver may still result in a proper orking system,
but the chance of signal disturbance ill increase and is therefore not recommended for critical
applications here signal drops cannot take place (e.g. in theatre environments).
Ayra chooses to inform the user about the theoretical max. operating distance as a reference, but
please be a are that similar ideal circumstances ill usually never be present during actual and
expected use of the product ithout signal drops. The recommended operating distance provides the
most optimal signal hile still being useful and reliable.
