information.

= Pay close attention for safety reasons or in order not to damage the device.

= Additional and useful information for the use of the data acquisition system ina fully safe manner.

= Special tips for using the data acquisition system in the best and fastest way !

Over 123 drawings, illustrations, and photos appear in this usage manual, which will help
increase your understanding.

This manual forms part of the device’s standard equipment. Read its contents
carefully before turning on the device. Please keep this manual for futurereference.

For your safety and that of the device
The following safety advices must be followed for your safety, and in order to avoid any
damage to the data acquisition system.
Batteries and Accessories
AStrO, AStrO 4T & PRO+ were designed to be run on two regular batteries : 1.5-volt type
AA , IEC Code (R6).
AStrO Formula & AStrO Formula 4T were designed to be run on two regular batteries :1.5-volt type C, IEC Code (RL14).



Note : It is imperative to utilize quality batteries by well known manufacturers
to eliminate the possibility of leaks. Damage caused by battery acid will beconsiderable and irreversible. Verify often the condition of the batteries when
not in use. Never leave uncharged batteries in the unit.
Any damage caused by battery acid will annul the warrenty.

Use only batteries and accessories approved by the manufacturer of the dataacquisition system and specifically designed for the model of data acquisition
system.



In order for you to obtain approved accessories, please contact your local
retailer.

Copyright  2005 Alfano, S.A. All rights reserved.

15



Use only a X20 type screwdriver (provided with your data acquisition system) to
attach the accessory connectors to the device.
Please, do not overtighten the connectors. Stop tightening the screws
as soon as the red joint is pressed down.
Please ensure the various connectors are attached in their correct location.

General Information
Serial numberYour data acquisition system has a unique 9-digit serial number. This serial number is an
important piece of information for the post-sales and technical services, which are provided
for our customers. Please keep this number handy (see menu 30. – page 67).
Security code
This code protects your data acquisition system from unauthorized use. To activate thiscode (see menu 25. Password – page 65).
Seal
The data acquisition system is perfectly sealed and water-resistant, but this does not meanthat it is totally waterproof (you cannot submerge it in water). You will have no problem
during races in the rain. Please ensure that the connectors are well-protected.
The data acquisition system is IP56 certified, which means that it is resistant to any dust
penetration and can be hit by a stream of water at medium pressure from all sides.
Magnetic strip or infrared
The data acquisition system described in this manual was designed specifically to work on
tracks equipped with magnetic strips. This system was developed by our research team andit is protected by a patent (EP 0632350). When seeking accuracy and quality, we suggest
you drive on tracks equipped with the Alfano magnetic strips. However, the data acquisition
system also works on tracks that are not equipped with Alfano magnetic strips through theuse of an infrared system, which is sold separately.
Remark: We support various types of infrared systems: our infrared sensor, which is soldseparately, works with most of the infrared transmitters available on the market. We also
sell infrared transmitters (see accessories - page 5).
The data acquisition system is attached by a cable to a magnetic strip sensor. This sensor isplaced under the vehicle, a few centimeters above the ground. When the magnetic strip
sensor passes over the magnetic strip on the track, the magnetic strip sensor is activatedand it sends an signal to the data acquisition system.
The magnetic strip is made up of small, special, permanent magnets. The magnetic strip
emits free, permanent energy for approximately 200 years. Once the magnetic sensor isinstalled on the vehicle, you can drive on every track equipped with magnetic strips, andthe system will work automatically, trouble free.

Copyright  2005 Alfano, S.A. All rights reserved.

16
We have more than 850 equipped tracks around the world, 460 of which are in Europe, andthe list is growing daily. We have a team of installers who work year round throughout theworld. A list of « equipped tracks » is regularly updated at the following website :www.alfano.be. Please visit it regularly!
An added feature of the magnetic strip is that it is in a straight line. While driving andcrossing this line, you need not worry about other drivers crossing the line at the sametime, because the magnetic sensor detects the signal immediately. This same precision does
not exist when you use an infrared system. The signal can be delayed or disrupted byinterference caused by other drivers between you and the transmitter. Also, the angle isquite large (17 degrees or more, depending on the system), whereas the magnetic strip is a
short line of less than one centimeter in width. If you are seeking quality and precision, themagnetic strip is superior !
Tracks including several sections
Tracks can be divided into several portions (which we call sections) through the use ofmagnetic strips or infrared sensors. The first thing to know is how many magnetic strips or
infrared sensors are placed on the track, and to set this up in the data acquisition system(see Menu 10. Strip Number – page 50).

Every time you drive over a magnetic strip, the data acquisition system records a segment
time. These segment times allow you to compare your time on different sections of the
track very accurately, and therefore you may tune your machine more effectively.
The total of the section will be equal to the total of one lap.

How to use
Use of keys
The data acquisition system is simple to use ! All of the features can be accessed with justtwo buttons. In the following section of this document, we will explain you how best to use
them.
Turning on
To turn on the data acquisition system, press the two buttons, right and left, and hold themfor two seconds. When you release the buttons, the display turns on and the system asks
you whether or not you would like to activate the backlighting of the screen. If you wish toactivate it, press the right-hand button to choose the ON option. Otherwise, choose the OFF
option by pressing the left-hand button. The data acquisition system will choose the OFF
option automatically after 2 seconds if nothing has been choosen.
Manual turning off
To turn off the data acquisition system, use the left-hand button to select Menu 1 :« System Off », and press the right-hand button.
Automatic turning off
The data acquisition system automatically turns off when not in use for 10 seconds.
Low battery warning signal
The system detects when the batteries are low. The 4 temperature lighted signals will begin
to blink rapidly one by one.

When the data acquisition system is in the START mode, 10 minutes after the system has
detected the batteries are low, it automatically returns to the STOP mode, and the message« CHANGE BAT » is displayed. The batteries must be replaced, otherwise the system will
not restart in the START mode and access to the menu « Config System » will be denied.



Note : If while the data acquisition system is in the START mode and thebattery current is broken the information may be lostThroughout the time in which the low battery warning signal is activated, theother signal lights and the backlight remain inactive, so as to reduce the use ofenergy and somewhat lengthen the time in which the data acquisition system
may be use.

Copyright  2005 Alfano, S.A. All rights reserved.

21

Installation
You must properly install the data acquisition system and its accessories before use. Please
read this chapter carefully.



Important : when not in use, the ports of the data acquisition system must
always be protected with the caps provided. See page 31.

AStrO, AStrO 4T & PRO+

These data acquisition systems are made in one single box : the batteries and sensors are
fitted onto the unit itself. This is very advantageous when you do not have a great deal ofspace, as is the case in a go-kart, for instance. These devices are better adapted to suchconditions.
In most cases, the data acquisition system is attached to the steering wheel with a M8 nut.
The two red-colored, rubber rings must be to each side of the steering wheel. The hard,
black-colored, plastic ring is used to keep the data acquisition system at a distance of 4
millimeters from the steering wheel.

When installing the device in place, ensure that the back side of the box is nottouching any part of the steering wheel. This will avoid causing damage to thedevice.

Copyright  2005 Alfano, S.A. All rights reserved.

22
AStrO Formula , AStrO Formula 4T

The AStrO Formula & AStrO Formula 4T are made up of two parts : the batteries and thesensors are fitted into a separate box, which is attached to the data acquisition system via acable. This specific layout provides several advantages. The main advantage is that the backof the data acquisition system is flat, which is quite helpful if you wish to install the device
on a dashboard. In addition, the batteries of the AStrO Formula & the AStrO Formula 4T
have a longer life span.
The data acquisition system is attached in place using 4 M5 screws, which are provided withthe unit.

When installing the unit in place, ensure that the back side of the box is nottouching any part of the steering wheel. This will avoid causing damage to theunit.

The accesory color codes
The back side of the data acquisition system is color coded for each of its sensors. The color
code on the end of the corresponding sensor must match that of the data acquisition system
port. Thus, making it virtually impossible to make a mistake !
Color codes are as follows :
Port
Port
Port
Port
Port

«A»
«B»
«C»
«D»
«E»

Yellow
Red
Red
Green
Blue

For the G- Force sensor
For temperature sensors (type NTC or type K)
For temperature sensors (type NTC or type K)
For the magnetic sensor or the infrared sensor
For the speed sensor



Make sure the color code on the port at the back of the data acquisition system
matches the color code on the sensor you wish to install.
Make sure the color code on the back of the data acquisition system and thesensor are placed on the same direction, to avoid attaching the connector backto front !
Also, make sure the connector fits in perfectly before screwing it. This must
be done without difficulty. If it is difficult to screw in, it is quite possible that thesensor you are trying to connect to the data acquisition system is in the wrong
port. Never force it in !

Please, use only a type TX20 screwdriver (you are provided with a screwdriverof this type) to attach the sensors in place.
Please, be careful not to overtighten the connectors and stop tightening
as soon as the red joint is pressed down.
In any case, make sure that the various sensors are properly fixed in placed.

The G- Force sensor
The G- Force sensor must be placed horizontally and level.
The sensor cable must be heading towards the back of the vehicle.
Installation on go-karts :Before installing the sensor on the go-kart, the G-Force sensor must be attached to thearticulated bracket, which was specifically designed for this purpose.

Then, the ensemble must be fitted to the nassau panel.

This articulated bracket allows the G- Force sensor to be installed horizontally.



Important : once installed, the G- Force sensor must be calibrated (menu 24.
G-Force calibration – page 64).
Important : before calibrating, make sure your vehicle is on a flat, horizontal
road.
Important : install the sensor in a place where the vehicle vibration is low,
because vibration may distort the G- Force calibration.



The G- Force sensor is coded with the color Yellow.
The sensor is equipped with the articulated bracket.

Temperature sensors
The data acquisition system enables to measure the temperature in the cooling circuit, as
well as the oil, cylinder head and exhaust gases ! The data acquisition system is able to use
either NTC or K type technology to perform these temperature measurements.
Sensors using the « NTC » technology, measure temperatures ranging from 0°C to 285°C,
depending on the sensor. This technology is used to mesure the temperature of the coolingliquid in the line (using an adapter) or on the cylinder head. Other sensors also allow
temperature measurement of the engine oil and of the spark plug.

Sensor using the « K » type thermocouple technology, measure temperatures as high as
1000°C. This technology is used for measuring the exhaust gas temperature.

Copyright  2005 Alfano, S.A. All rights reserved.

26
The AStrO 4T & AstrO Formula 4T temperature sensors
These data acquisition systems may support 4 temperature sensors. A specially designed
adapter is utilized. This adapter is made up of one male plug to be connected on the side ofthe data acquisition system, and two female plugs to be connected to the sensors.

This adapter allows connection to a single port of the data acquisition syst., « B » or « C »,1 K type thermocouple temperature sensor + 1 NTC type temperature sensor

Color code : sensors and extension cables using the NTC type technology :BLACK connector, RED-colored sticker
Color code : sensors and extension cables using the K type thermocouple
technology :RED connector, RED-colored stickerAll the temperature sensors are +/- 40 centimeters in length, and all end with amale connector (see page 3 – List of accessories.)
Extension cables of different lengths are sold separately.

The influence of interferences from the high tension coil on the temperature
reading.
The data acquisition systems are electronically protected from interferences.
However, highly aggressive interferences may influence – to a smaller or alarger extent – on the temperatures displayed. To avoid this phenomenon, wesuggest you install :a spark plug with an internal resistance, ora spark plug cap with an internal resistance

The sensor and the extension cable are connected with two screws (this is therecommended method).
To connect and disconnect rapidly, remove the two screws on the maleconnector and use the rubber ring placed on the female connector.

Warning : the seal is not guaranteed when using this last method.

Pressure sensor Oil and Fuel for the AStrO 4T & AStrO Formula 4T

The sensor is connected to
Port B and C of the unit which is the same
port used for the NTC1 and NTC2
temperature connection.

- The Pressure sensor is color code red.

The magnetic strip sensor
The magnetic strip sensor is placed as close as possible to the road.
It must be placed on the floor pan of your vehicle, parallel to the vehicle.

Important : We recommend you place the magnetic strip sensor in front of the
speed sensor, so that it receives the impulse first from the track magnetic strip.
This way, the system may eliminate the track magnetic strip impulse received
by the speed sensor, which will cause an abnormal speed rise. See chapter« The influence of the track magnetic strip on the speed sensor » (page29).

- The magnetic strip sensor is coded with the color Green.
- The sensor is provided with a M6 bolt for its attachement.

The infrared sensor and transmitter
The infrared sensor is placed in such a way that it will accurately detect the signals from theinfrared sensors placed at the edge of the track. Receiver and transmitter must be face toface at the same height.

Copyright  2005 Alfano, S.A. All rights reserved.

28



- Make sure you properly align your infrared receiver and transmitter.
- The infrared sensor is coded with the color Green.

The speed sensor
The speed sensor must be attached to a non-moving part of your vehicle. The speed sensor
detects the passage of a permanent magnet previously placed on either wheel or on thetransmission shaft. Every time the magnet passes over, the data acquisition system
calculates your speed by knowing the circumference of your wheels and the time it took for
you to make a lap.
Placement on go-karts
If you decide to place the sensor on one of your front tires, the sensor is to be placed onto
the spindle of the axle using the bracket provided, (large or small model) and a small
permanent magnet is attached on the inner side of the rim using an adhesive strip.

However, if you decide to place the sensor on the transmission shaft at the back of the gokart, the sensor is to be placed on a fixed part of the chassis with the bracket provided(large or small model) and a specially magnetized collar is placed on the transmission shaft.



Important : In order to obtain the accurate speed, only one magnet is to beplaced on the transmission shaft or on one of your wheels.
In order to check whether the speed sensor is properly in place, go to Menu 17.
Speed Config (page 57) and make sure that the 2 temperature lighted signalsof the data acquisition system light up every time the speed sensor receives thesignal from the magnet, or in other words, every time the speed sensor is in
front of the magnet.

Copyright  2005 Alfano, S.A. All rights reserved.

29
The influence of the track’s magnetic strip on the speed sensor
If the speed sensor is placed too close to the road, it will receive an extra impulse from thetrack’s magnetic strip, and the speed value will increase abnormally when passing over themagnetic strip.
Preferably, in order to obtain the accurate speed, we suggest you place the speed sensor insuch a way that it does not receive the impulse from the magnetic strip (place the sensor as
high as possible away from the road).
If you cannot place the speed sensor in such a way so as to avoid the influence of the
track’s magnetic strip, there is an automatic electronic filter. But the filter will only work if
the magnetic strip sensor of the data acquisition system is placed in front of the speed
sensor. In fact, the track’s magnetic strip must be first to pick up the signal, so that thedata acquisition system is ready to eliminate the impulse from the track’s magnetic strip
received by the speed sensor.
Note : the filter is able to detect and eliminate around 95% of the impulse from themagnetic strip.

Important : in order for the filter to work properly, place the magnetic strip
sensor in front of the speed sensor, as explained above.
The speed sensor is coded with the color Blue.

The engine speed sensor
The data acquisition system makes it possible to measure the speed of your engine (RPM).
There are different engines, each with their own particular ignition, especially in terms of
power. The data acquisition system has two inputs for measuring the engine speed. The
first input, i.e. port « G », is used for the so-called normal power ignitions; and the second
input, i.e. port « F », is used for ignitions with weaker power.

In the case of an engine whose ignition power is normal, use port « G ». It is the dataacquisition system’s main port. Take the black wire provided with the data acquisition
system, place this wire along the spark plug cable using the spiral sheath made of black
plastic (provided). Then, pass the other end of the cable in a coil through the two holes
located at the back of the data acquisition system : port « G ».

Copyright  2005 Alfano, S.A. All rights reserved.

30

However, if the ignition power of your engine is weak, you might notice some fluctuation in
the measurement of your engine speed. This is due to a large extent to the weak power ofthe ignition. The data acquisition system will not be able to receive the correct signals. In
this case, you must use a high-sensitivity wire, which is sold separately. It was speciallydesigned for this type of ignition. The procedure is the same : take the high-sensitivity wire,
place it along the spark plug using the spiral sheath of black plastic, then splice its banana
connection into port « F » of the data acquisition system.
Extra trick : when you increase the contact surface of the high-sensitivity black wire withthe high-voltage spark plug wire, you are increasing proportionally the intensity of thesignal. For instance : if the contact surface is increased from 10 to 20 cm, the signal
intensity is doubled.
Another type of ignition > explanation : the coil that generates the high voltage to power
the spark plug is located on the spark plug itself. In this case, there is not enough room togather the high voltage required for operation of the data acquisition system’s lap counter.
There is a solution : you must connect electrically (using bare wires) the high-sensitivity
wire that is sold separately onto one of the low-voltage wires that power the high-voltage
coil, and splice its banana connector into port « F » of the data acquisition system.

In the event that the high-voltage coil is attached to the spark plug, only one of
the two low-voltage wires that power the high-voltage coil allows operation of
the lap-counter.
Test the two wires before carrying out the final installation of the black wire.

A black plastic, spiral-shaped sheath, provided with the data acquisition system,
is used to attach the black wire to the high-voltage spark plug wire.

34Management of the FLASH memory
The FLASH memory is divided into 2 parts.
-

The first part of the memory is used to record detailed information every 0.1 of asecond :
o

RPM
Temperatures
Speed
G-Force
Gearbox ratio
As well as lap times and section times

Most of this information is displayed in the « VIEW » mode of the data acquisition system,
as well as in the ALFANO VISION (page 67), and can be displayed in full detail on a PC using
the « LynX » program. The time required to fill this first part of the memory depends on
the number of sensors connected ; this time ranges between +/- 130 Minutes and +/- 60
Minutes.
Once back to the STOP mode, the remaining recording time is displayed, for instance « 123
MIN ». This is the recording time still available in this first part of the memory.

-

The second part of the memory is used to record the main information for eachlap. (Detailed information is not recorded and the VIEW mode cannot be accessed).
o
o
o
o
o

High and low RPM for each lap
High and low temperatures for each lap
High and low speed for each lap
Lap time
Section times

The time available to fill this second part of the memory ranges between 24 Hours and 40
Hours.
The data acquisition system indicates the automatic change from the first part to the second
part of the memory by activating the 4 temperature lights, which blink for 10 seconds. The
data acquisition system then starts a new race.

Copyright  2005 Alfano, S.A. All rights reserved.

35
Once back in the STOP mode of the second part of the memory, you will see on thedisplay the number of laps still available to save, for instance :752 laps (752 LAPS).

When the message « - - FULL - - » is displayed that means no more data can be recorded.
In that case, the data acquisition system will not work in the START mode and must be
reset first « Menu 06. Data Reset » (see page 47).

The data acquisition system memory is set up to allow use for over 24 HOURS.
In the second part of the memory,the « VIEW » mode cannot be accessed (infact, detailed information will not be saved) while displaying laps in mode 02.
Recall, 04. Best Laps et 05. Theor Lap.



IMPORTANT : in START mode, the system is continuously saving data in a
FLASH memory. The data saved in this memory cannot be partially deleted.
This means that data is being saved from the time you drive over the magnetic
strip until you return to the STOP mode though this information is not utilized, ittakes up space in the memory.
Therefore, it is very IMPORTANT that you go to STOP mode as soon as
possible, to avoid filling the memory with useless information.

The « VIEW » mode allows you to view one full lap in detail. Actually, the data acquisition
system is able to run through a saved lap from start to finish, dividing it into tenths of asecond (0.1 Sec), at a pace you choose. For instance : if the lap time you choose is 57.34
seconds, you will be able to view 574 screens, which represent one full lap around the track.
On each of these screens, you will be able to see, in real time, the advancement of lap timeby tenths of a second (0.1 Sec), RPM, temperatures, speed, gearbox ratio, and the arrows
which represent lateral and longitudinal accelerations (see the vehicle turning right, left,
accelerating and decelerating).
When you return into the « VIEW » mode, the data acquisition system is at the start of thelap. You will note that all the data displayed refer to the beginning of the lap (As if you areon the first magnetic strip).

In the event that the track has only one magnetic strip, the lap time is displayed in thecorner.
On tracks with several magnetic strips, you will also notice that the data acquisition system
is able, when viewing the track, to position itself accurately over each magnetic strip, inorder to display detailed information at that specific location. The central figure below shows
the data acquisition system on the magnetic strip 2, between section 1 and section 2.

Thanks to this technological advancement, you will get accurate information, anywhere
along the track, in order to understand and improve the tuning of your machine and, ofcourse, your driving.
While running through the lap, you may also see 4 arrows on
the display of the data acquisition system :Copyright  2005 Alfano, S.A. All rights reserved.
