UNIPRO – The original Laptimer 6
General Information
History of Unipro
Unipro was founded in 1987 after inventing the world’s first Laptimer. It could only measure lap
times and was produced in very small quantities. We still have one of the first six Laptimers
produced and of course it is still working – after more than 20 years! In 1991 we did something
people said couldn’t be done. We build the first Laptimer with RPM sensing integrated. This really
helped the drivers to see how their engine was performing. In 1996, we made the first Laptimer
with two temperature inputs and many other features not seen before. We made the unique split
feature using a wheel sensor to divide the track into different segments (up to 9 segments), a
digital signal processing of the RPM signal giving the most precise RPM value ever seen. You could
even connect a portable, battery driven printer to the Laptimer and get all you valuable
information on paper! In 2002, we decided to reinvent the Unipro Laptimer from scratch again!
Your Unipro Laptimer is a result of this reinvention. We have made so many new inventions and
features that we can’t get into them here, but now you really can use the Laptimer as a tool to go
faster, faster!
Philosophy
People often ask us why we make Laptimers the way we do and we would like to tell you about
our philosophy:
Our top models will always have a separate display
There are several positive sides and only one negative side to this:
•It enables us to make an ultra thin display unit with a very appealing design
•It will keep all the cables needed away from the steering wheel and thereby enable the
driver to drive the kart!
•It enables us to use two separated processors and keeping at lot of processing power free
for the advanced calculations needed to give you the precise data we offer.
•The only negative side about the separated systems is that the cost is higher!
We will only make systems with enough buttons
There are so many features at your fingertips, but if your Laptimer has to few buttons, it will be
difficult to find the needed features fast enough. We will always make sure that the Unipro
Laptimer has enough buttons so it is fast and easy to operate.
We use as much energy on the cables and sensors as on the Laptimer itself
Every cable is hand built with the finest cable and finest connectors. We will not try to make
money on spare parts that has to be replaced very often. We build every part of the Laptimer with
the intention that it should never break!

Commonly used words
Throughout this manual, we use many technical words and terms. In this section we will explain
the most commonly used technical words.
BAUD (BPS)
Baud is another word for bit per seconds (bps). It tells you how many bits can be moved in a wire
or in the air per second. Speeds of 115200 baud can in theory move 11520 bytes per second.
Baud is used to measure serial speed, normally known from RS232.
DISPLAY
The display is also known as the LCD, monitor or screen.
DSP (DIGITAL SIGNAL PROCESSING)
Analogue signals are transformed into digital signals and then processed in a computer. This is
called DSP and it can be done in a dedicated processor called a DSP or in a normal processor like
the one used in the Laptimer. Using DSP algorithms, it is possible to do a lot of advanced
processing.
FILTER
Remove something unwanted. One example of the use of filters in your Laptimer, is to remove
unwanted noise when the RPM of your engine is measured.
FIRST LAP
The first part of the race. It is the segment from the pit to the finish line. It is sometimes called
the out lap. This segment of the track is important because it is used to align the Laptimer to the
finish line.
INFRARED
Invisible light beam in the infrared band. Normally just referred to as IR. The remote control for
your TV or stereo also uses infrared light.
IRDA
Infrared Data Association. This is an infrared communication standard used in Laptops, PDAs,
PalmPilots, mobile phones, printers and a lot more. The IrDA standard is both physical hardware
and software.
LOGGING
Logging is storing data continues in a memory. The idea of logging is to store everything for later
analysis – in the pit or on your PC.
LOOP
A Loop is a wire in the asphalt. The Loop is sending a signal that the Laptimer pick up every time
it passes the loop. The Loop must be an active AMB Loop in order to trigger the Laptimer.

UNIPRO – The original Laptimer 8
LED LAMPS
A LED or Light Emitting Diode is a rather simple semiconductor circuit which emits light without
producing waste heat. This means, it needs only very little energy, about 5% of a normal light
bulb to produce the same amount of light. We use ultra bright LEDs as warning lamps in the
display unit.
MAGNET STRIPE
A piece of magnet going all the way across the track. Used to trigger the Laptimer as an
alternative to the loop.
MAIN BOX
Most of the electronic is located in the main box. This is the box with all the connectors, memory
and batteries.
MEMORY
A lot of different memory is used for storing the program, setup, lap times and logged data. The
most used type of memory is Flash or EEPROM. Both types are used in this Laptimer.
PROCESSOR
The part of the Laptimer with all the intelligence and calculating power. It is also called a CPU, μP,
μC or just the computer.
PROTOCOL
A protocol is a piece of software that sets the standard for how the systems work. For example
the process for sending data through infrared light is defined in the Infrared Data Association
Protocol – the IrDA protocol.
RECEIVER
The receiver picks up the trigger signal and starts the Laptimers stopwatch. There are different
types of receivers: loop, magnet stripe and infrared. Your Unipro Laptimer supports all kinds of
receivers.
TRIGGER
The Laptimer trigs when it passes the finish line. The trigger can be either infrared light, a magnet
stripe or a Loop signal.
TELEMETRY
A way of sending data through the air from the running kart to the pit. It is illegal during official
races and can only be used for training.

UNIPRO – The original Laptimer 9
Receiver types
The Unipro Laptimer supports all kind of receivers. The different receivers are good for different
things, and sometimes you need to change between several types. Unfortunately, none of them is
perfect. We have made a short list of pros and cons of the different receiver types.
LOOP (AMB)
9Very precise trig
9Long sensing distance.
9Full electronic systems without any problems at all.
9Not sensitive to vibrations.
9Use very little power in the Laptimer.
2AMB active Loop only. Will not work on a passive Loop.
2Sometimes the Loop is turned off.
2Only one on a track. Cannot be used for splits like several stripes.
MAGNET (STRIPE)
9Very precise trig.
9Can have more than one on a track for splits.
9Use very little power in the Laptimer.
2Mechanical system.
2Can in worst case generate false trigs with excessive vibrations.
IR (INFRARED)
9Can be used where no Loop or Magnets are present.
9Can be used far from the asphalt.
2Not as precise trig because the beam is spreading across the track.
2Can miss a trig if another driver is covering the infrared beam.
2Beam can hit the kart more than once on the track.
2Need an IR transmitter placed on the track.
2Use power in the Laptimer.
Unipro recommends using the Loop receiver. This is the perfect receiver type if there is an active
AMB Loop present at the track. Second choice is the Magnet receiver, but if you are at a race on a
car park, the IR receiver is needed.
Split types
Dividing the track into smaller sections is one of the most important features of the Laptimer. It
will help drivers at every level and in every type of kart to go faster, faster. There are two ways of
using splits with your Unipro Laptimer:
1. Splits with magnet stripes
2. Splits with wheel sensor

UNIPRO – The original Laptimer 10
SPLITS WITH MAGNET STRIPES
If the track has more than one magnet stripe, it is possible to use the rest as split points. The
problem with this method is that you do not have enough split points and you cannot place them
yourself. You will no longer be able to view corner information because you typically have several
corners per segment. Therefore you should only use the magnet stripes as split points if you are
using a kart with four-wheel brakes.
SPLITS WITH WHEEL SENSOR
Using the high precision wheel sensor, you can define up to 8 points on the track as split points.
This will divide the track in up to 9 segments giving you the possibility to optimize your kart setup
and driving style for each segment of the track individually. You can set the splits in setup mode,
during the first lap, wireless from the Data Analyser or using the USB cable from the PC Analyser
program.
Communication types
An important feature of a Laptimer is the communication between the Laptimer and other devices.
Typically you will use the Laptimer on the track for quick analysis, but if you want to go deeper
into the analysis, you need to get the data away from the Laptimer to a PC or printer. This section
describes the different communication standards.
SERIAL
Serial communications is normally referred to as RS232. It is a low speed, wire interface standard
used in old Laptimers. RS232 is still used from the Data Analyser to the portable DPU printers, but
the RS232 port is now removed from most modern Laptops. The speed typical ranges between
9600 baud and 115.200 baud.
IRDA
IrDA is a shortcut for Infrared Data Association. It is a standard for communicating with invisible
light. IrDA is a standard consisting of many levels. The lower ones describe the physical link. This
is the one with use for communicating between the Laptimer and the Data Analyser. The physical
speed is 115.200 baud, but because of overhead with error detections and retransmission, the
real payload is around 75% of the theoretical limit.
With the higher levels of the IrDA protocol, it is possible to communicate with PDAs, PalmPilots,
Laptops, mobile phones and many other devices. It is possible to choose the full IrDA protocol in
the Laptimer, enabling it to talk directly with a PDA. The higher levels add a lot of overhead, and
it will lower the real speed of the transfer. The protocol is either a primary (master) or secondary
(slave). Unipro uses a secondary protocol in the Laptimer and a primary protocol in the Data
Analyser. The distance for an IrDA link is normally around 30 – 100 cm (10“ – 40“) but it is very
depending on the surroundings. Fluorescent light and sun light will limit the possible range.
