Assembly hints
1. Assembly (Skipping this can lead to troubles ! )
Ok, so we have your attention. These hints will help you to make this project
successful. Read them carefully.
1.1 Make sure you have the right tools:
 A good quality soldering iron (25-40W) with a
small tip.
 Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to
the tip, to give it a wet look. This is called ‘thinning’ and will protect
the tip, and enables you to make good connections. When solder
rolls off the tip, it needs cleaning.
 Thin raisin-core solder. Do not use any flux or grease.
 A diagonal cutter to trim excess wires. To avoid injury when cutting
excess leads, hold the lead so they cannot fly towards the eyes.
 Needle nose pliers, for bending leads, or to hold compo-
nents in place.
 Small blade and Phillips screwdrivers. A basic range
is fine.
For some projects, a basic multi-meter is required, or might
be handy
1.2 Assembly Hints :
Make sure the skill level matches your experience, to avoid disappointments.
Follow the instructions carefully. Read and understand the entire step before
you perform each operation.
Perform the assembly in the correct order as stated in this manual
Position all parts on the PCB (Printed Circuit Board) as shown on the draw-
ings.
Values on the circuit diagram are subject to changes.
Values in this assembly guide are correct*

Use the check-boxes to mark your progress.
Please read the included information on safety and customer service
* Typographical inaccuracies excluded. Always look for possible last minute
manual updates, indicated as ‘NOTE’ on a separate leaflet.
1.3 Soldering Hints :
1- Mount the component against the PCB sur-
face and carefully solder the leads
2- Make sure the solder joints are cone-shaped
and shiny
3- Trim excess leads as close as possible to the
solder joint
REMOVE THEM FROM THE TAPE ONE AT A
TIME !

Solder the 3-pole female print connector to the XLR connector using the figure
below to check the accuracy of the connections (see fig. 2.0 & 3.0).
Now mount the female 3-pole XLR connector in the provided opening in the
upper part of the housing, securing it with the included selftapping screws (flat
head 2.9 x 6.5mm), see figure 4.0.

Fix the PCB using 4 screws ( 2.9 x 6,5mm).
Connect the wired connector to 3p header (SK3).
If stand alone function is used, connect the battery to the connector and in-
sert the battery in the battery compartment as indicated in fig. 5.0.
Close the enclosure with the longest supplied screws (2.9 x 9.5mm).
Affix the supplied front sticker on the top of the enclosure.

Software installation and test
 Browse through the CD and open the K8062 folder.
 Check the appropriate PDF files for further information.
The ‘light player’ software is installed in the folder by default: c:\program files\DMX
This is a screen shot of the DMX_demo software, used tot test the unit or to make some simple shows.
You will find the latest version of the software on our website
21. Software installation
22. Stand alone test mode
For the stand alone DMX test mode a 9V battery must be connected between
the connectors SK1 (+) and SK2 (-).
Test button SW1 is used to control the operation of the test mode.
Operation :
Do not connect the unit to the USB cable.
A short button press turns the unit on. - Power LED goes on and the unit
starts to send DMX code "0" on all the 512 DMX channels.
Next button press increments the code on all the channels to '1', next button
press increments to '2' etc.
The "DMX signal" LED starts to light periodically when the test button is
pressed for some times.
The LED's flashes are longer after pressing the button for several times.
Pressing the button 256 times the internal counter rolls back to 0 and the unit
starts again to send code "0" on all the 512 DMX channels.
If you use e.g. a dimmer as a test equipment you should see how the
intensity of the light increases on every button press.
To turn the power off, keep pressing the button about 9 seconds until the
power LED goes off.
