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 enclosu re
 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

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 o r c loth , to ke ep it c lean ; th en apply so lder to th e t ip, to g ive it a wet look. This is called ‘thinn ing’ an d w ill

protect the tip, an d enab les you t o make good conn ections. When so lder ro lls of f th e tip, it ne eds clean ing.

• Thin raisin-core solder. Do not use any flux or grease.

• A diagonal cutter to trim excess wires. To avoid in jury wh en cutting ex cess leads, ho ld the lead so th ey

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 poss ible last m inu te manu al 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
