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 components 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 drawings.
⇒ 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 surface 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

Set-up
The K8050 features 4 operating modes, selectable with diodes D16 and D17.
1) 15 independent outputs.
2) 15 rotary outputs
3) 7 independent outputs & 8 rotary outputs.
4) 7 rotary outputs & 8 rotary outputs (independent from each other).
Momentary (push button-) function : Hold the key to activate the output and release the key to deactivate it.
Toggle function : Operates according to the principle of a classic switch, i.e. you have to press the key once to
switch and press again to deactivate it.

Not mounted Not mounted 1 (D4 K6710)*
Not mounted Mounted 2 (D6 K6710)*
Mounted Not mounted 3 (D5 K6710)*
For each output :
If a momentary output is needed, DO NOT mount a diode for the
corresponding output D1 to D15.
If a toggle output is needed, MOUNT a diode for the corresponding
output D1 to D15.
ADDRESS SELECTION
Different possibilities in conjunction with diode setup:
The address selection allows you to operate up to 3 receivers in the same room without interference. Each
receiver shall have its own address setting.
HINT: 3 receivers in the same room gives you 45 outputs thanks to address setting.

ATTENTION: the receivers can only be operated by a transmitter allowing address setting. For the setting
of the transmitter, we refer to the manuals of the kits in question.
* K6710 :
To make the transmitter K6710 work with the receiver K8050, the identification of the transmitter must be
adjusted to that of the receiver:
Address 1: mount diode D4
Address 2: mount diode D6
Address 3: mount diode D5
SEVERAL IR RECEIVERS
If you wish to connect more than one receiver to your system, they should be connected in parallel (see below fig
1.0). To preserve the transmission quality it’s advisable to use twin - shielded cable (Ordernr. : PUC2025).
