Features & Specifications
The K8063 is a 7-segment display which can be controlled by a two-wire serial connection, using the RS232 protocol. The
protocol is platform-independent i.e. any computer running any programming language can control the K8063, as long as it
is equipped with a serial port. Up to 255 units can be individually addressed, allowing you to create large display systems for
e.g. scoreboards, clocks, timers, thermometers, games, …
Features
Red bright 57mm jumbo 7-segment display
Complete with snap-in enclosure
Multiple units can easily be linked in order to create larger readouts for different purposes e.g. scorekeeping, timing,
counting, ...
Easy platform-independent control via three-wire RS232 interface
Up to 255 separate units can be addressed
Tested with distances of up to 50m between PC and display
Use our optional PCUSB6 for USB connection
Specifications
Power supply: 9 to 12Vdc / 120mA per display
RS232 interface: 2400baud / 8databits / no parity / 1 stop bit
Dimensions: 74 x 58.5 x 32mm

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 oftenon a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it awet look. This is called ‘thinning’ and will
protect the tip, and enables you to make goodconnections. 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 whencutting 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
REMOVE THEM FROM THE TAPE ONE AT A TIME !
AXIAL COMPONENTS ARE TAPED IN THE
CORRECT MOUNTING SEQUENCE !
You will find the colour code for the resistances and the LEDs in the HALG
(general manual) and on our website: http://www.velleman.be/common/service.aspx

Construction
Mount the spacers onto the PCB with the 2 in-
cluded screws and install the digit display on the
solder side of the PCB. Pay attention to the posi-
tion of the decimal point, see figure 1.0.
Then turn the PCB around and place it into the housing with the display
towards the front, see figure 2.0.

Test
When the assembly has been completed, we recommended to test each
individual unit before daisy-chaining them. Make sure SK7 (address jumper) is
put in place, see figure 4.0.
Connect a 9 to 12VDC power supply to the pins GND and +V.
At power-on, the K8063 will display .0123456789 (segment test).
Next, it will display its current address (default : 1) for a couple of seconds.
At this time, the K8063 allows you to select an address ranging from 0 to 19*.
Simply wait until the desired address is displayed and remove the SK7
address jumper. ( note : addresses 0 to 9 are displayed as 0 to 9, addresses
10 to 19 are displayed as 0. to 9. (note the dot).
The K8063 will loop the addresses until the jumper is removed, so if you have missed the desired address,
you can wait a while and it will appear again.
Once you have removed the jumper, the K8063 stops looping and after a couple of seconds the display will
turn blank. The selected address is now stored in its memory.
*If you require 20 or more different addresses, you can configure them when the K8063 units are hooked-up
to the computer (see further in this manual).
