Dear Customer,
Thank you for selecting a product from the GET by Athena data acquisition line.
We are sure that our passion and experience will be able to successfully reach maximum
performance in all the competitions in which you want to participate. Therefore please read this
manual as we are sur e that it can help you to properly use your new GET by Athena device.
Thanks to GPS technology, the devices in the SL1 Data Logger family are able to acquire not only
signals from the sensors connected to them, but also vehicle trajectories and speed.
The data download and configuration of the SL1 Data Logger is managed using the LynXLog
software.
The acquired data can be analysed using the WinTAX4 Junior* software.
The purpose of this manual is to illustrate the functions of the SL1 Data Logger to the end user.
*WinTAX Junior requires an activation code, to obtain it contact us at [e-mail].

2 WHY ACQUIRE...
3 GPS SYSTEM
Data acquisition during test sessions is becoming increasingly important because it permits:
• Reducing the vehicle configuration time.
• Correcting driving errors.
• Controlling vehicle behaviour, statically and dynamically.
• Viewing all the acquired parameters.
• Controlling engine and chassis performance continuously.
• Viewing the lap times of a session once downloaded.
The GPS system (Global Positioning System), on which your GET system is based, uses an algorithm
in order to determine the position of the GPS module that receives the signal transmitted by the
satellites.
By measuring the time a radio signal needs to travel the distance between the satellite and the
receiver and by knowing the precise position of at least 4 satellites, it is possible to identify the 3D
position of the receiver.
24 GPS satellites in orbit, inclined 55 degrees with respect to the equator, are located between
18000 and 20000 km from the earth and rotate around it once every 12 hours.
The satellites transmit a signal between 1.2 and 1.5 GHZ (to prevent errors resulting from
atmospheric refraction) generated by a single oscillator (atomic clock).
The transmitted data contain information about the orbit of the satellites and the time of the
signal, which permit the receiver to define its position on the earth's surface.
The lap times are obtained via GPS: this solution eliminates the need to use
inconvenient beacons on the track and helps provide a time reference during data
analysis.
The GPS uses a stochastic algorithm and is strongly influenced by the quality of the
received signal.
In the case of magnetic or environmental interference, data quality is not
guaranteed.
There must be a minimum number of 5 received satellites to guarantee the quality
of the lap times.

3.1 FIX GPS
It is necessary to “fix” the satellites to obtain the trajectories and lap times in the acquisitions.
The minimum number of satellites for correct acquisition is 5.
In fixed applications (example Dyno sessions) GPS is not required.
NOTE: The SL1 Data Logger continues to search for satellites during acquisition, which permits
starting acquisition also without GPS data.
In this case, it is probable that the trajectories, which are then displayed by the software, are
compromised.
Evidence of this are quick changes in vehicle position (spikes), also in the order of Km!!!
4 NECESSARY REQUIREMENTS...
The following is required to acquire data:
• Analogue signals or digital data (e.g CAN bus) coming from the vehicle
• SL1 configured correctly to acquire the desired data
• Personal computer
• Software LynXLog (required to download data and configure SL1)
• Software WinTAX4 (required to analyse the downloaded data)
The SL1 Data Logger can be connected to the vehicle (or the sensors) using the
specific cable (refer to Annex 3).

5 SL1: INSTALLATION
The SL1 Data Logger is designed to be easily installed in all vehicles.
With the dedicated cables, the Athena Evolution ECU (example RX1PRO) can be directly connected
via CAN bus.
For electrical connections, see Annex 2 and Annex 3 of this manual.
5.1 INSTALLING THE GPS ANTENNA
Refer to the following instructions to install the GPS antenna properly:
• Pay particular attention when moving the GPS antenna: Avoid impacts and check that the
cables are in perfect condition.
• Fix the antenna outside the vehicle: obstacles near the antenna could reduce the sensor's
reception ability. An incorrect position could cause an incorrect lap time, incorrect acquisitions
and trajectories.
• Do not twist the antenna cable with other cables (especially around high voltage cables): this
could cause inductive interference and therefore problems during operation.
• Do not pass the antenna cable around the cable of the spark plug or other electromagnetic
fields. In motorcycles, it is preferable to pass the cable outside the chassis, but always in a
protected area.
• Fasten the GPS connector to the antenna input of the SL1 Data Logger without applying
excessive force, do not use tools for tightening.
Some suggestions for fixing the antenna:
• Racing motorcycle: fasten the antenna in the rear of the motorcycle, away from heat sources
(exhaust) or in the instrument panel area (above).
• Off-road motorcycle: fasten the antenna on the handlebar.
• Automobile: fasten the antenna on the roof of the automobile.
• Kart: fasten the antenna on the top of the board, if necessary make a support to position the
sensor in the appropriate direction.
