thank you for choosing a GET DATA ACQUISITION AND ANALYSIS SYSTEMS by Athena.
We are sure that our passion and exper ience will help you to express successf ully in all competitions,
we ask you to read carefully this user manual. We are confident that this will help you in the use
of you new product GET by Athena.
SL1 Data Logger family , due to GPS technology, can log not only signal from connected sensors
but also data concerning trajectories and vehicle speed.
Data download and configuration of SL1 datalogger are done by LynXLog software.
LynXLog installer includes WinTAX4 Junior analysis software*.
This manual is dedicated to illustrate to the end user information on S L1 datalogger functions.
*WinTAX Junior requires activation code: to get it please contact us.
THIS IS A PRE-SERIES VERSION OF SL1
SOME FEATURES (WHICH ARE PRESENT IN M40 FAMILY) AREN’T IMPLEMENTED YET.
SUCH AS:
• POLYLINE CALIBRATION
• BUILT INERTIAL PLATFORM MANAGEMENT
• CHANNEL REAL TIME VIEW
• AUTOMATIC LAP SPLIT
• TRACK CREATION
PLEASE NOTE: LAST TWO FUNCTIONS CAN BE DONE BY WinTAX4 SOFTWARE.
ANYWAY WE ARE FOCUSED TO SOLVE EVERYTHING AS SOON AS POSSIBLE.
WE RECOMENDED TO EXECUTE LynXLog UPDATES WHEN THEY ARE SUGGESTED.
THANK YOU FOR YOUR COOPERATION

Logging data during test sessions or test bench is becoming more and more important because:
• You can reduce setup time on the vehicle
• You can solve driving mistakes
• You can evaluate vehicle behaviour statically and dynamically
• You can visualize all logged parameters
• You can check continuously engine and chassis performances
• You can see lap times once downloaded

3 GPS SYSTEM
GPS (Global Positioning System) system, on which your GET system is based, uses a spherical
positioning algorithm in order to identify the position of receiver the signal coming from satellites.
Measuring the time needed by a radio signal to cover the distance satellite-receiver and knowing
the precise position of at least 4 satellites, it is possible to identify the 3D position of the receiver.
24 GPS satellites, arranged in orbits inclined at 55 degrees to the equator, are between 18000
and 20000 km from the Earth and they rotate completely in 12 hours.
Satellites transmit signals of 1.2 and 1.5 GHz (to avoid errors coming from atmosphere refraction)
originated by a single oscillator (atomic clock). Transmitted data contain information on satellite’s
orbit and time signal (messages of Ephemeris) that permit to the receiver to define position on
earth surface.
Time lapping is done via GPS: this solution avoid uncomfortable beacons
side the track and help to have timing references during data analysis.
GPS is a stochastic algorithm and it is strictly linked to the correct signal
receiving. In case of electromagnetic or ambient interferences the quality
of data is not guaranteed.
The minimum received number of satellites in order to guarantee a proper
quality in time lapping is 5.
In order to install properly the GPS antenna please refer to the following instructions:
• Be really careful during GPS antenna movement: Avoid shocks and verify that connector and
cable are in a perfect shape
• Fix the antenna outside the vehicle: obstacles near to the antenna could cause a reduction to
the receiving capabilities of the sensor. A wrong position could cause an incorrect lap timing,
wrong data acquisition and wrong trajectories
• Do not twist the antenna cable around other cables (especially around high voltage plugs
wiring): this could cause inductive interferences and cause problems during the functioning
• Let pass the antenna cable as far as possible from spark plugs and other electromagnetic
field. In motorbikes it is preferable to run the cable out of the chassis but in any case in a
protected zone
• Fix the GPS connector to the ANTENNA input in MD40 without use excessive torque: do not
use tools
Some suggestions to fix the antenna:
• Speed bikes: fix the antenna in the far back part of the motorbike away from heat sources
(exhaust) or in cockpit area (on top of it).
• Off-road bike: fix the antenna on handlebar handle pad.
• Car: fix the antenna on top of the roof.
• Kart: fix the antenna on the higher part of front number plate, if needed manufacture a support
to address the sensor in the proper direction.
3.2 GPS FIXING
You need to “fix” satellites in order to get trajectories and lap times in analysis software.
The minimum number of satellites to get a correct acquisition is 5.
In fixed application (e.g. dyno sessions) you do not need GPS.
NOTE: SL1 will continue to search satellites during logging. This permit to start the acquisition
also without GPS data. In this case it will be probable that trajectories visualization (done via
software) could be compromise.
The evidence of this phenomena are fast variations on the position of vehicle (spike), up to
some kilometres!!!!
SL1 datalogger can be turned on through MAIN connector or via USB port.
Second options allows data download and logger configuration while system is unpowered (very
useful in battery-less application).
PLEASE NOTE: if system has be powered via USB port auxiliary voltage (5VREF) isn’t available:
this may cause wrong signals on active sensors connected to AN1, AN2 and AN3 inputs.
11 LYNXLOG SOFTWARE INTERFACE
SL1 datalogger requires LynXLog software: it is the interface between datalogger and you which
allows to:
• download and save recorded data to a PC for analysis.
• configure data logging parameters (channels properties, log triggers etc.)
• configure system parameters (e.g. LEDs brightness or GPS dynamics )
See LynXLog starting page in picture below:
LynXLog home page can be divided in three area:

LynXLog soft ware will save all downloaded data (sessions) in a specific folder called Base Directory.
User can change default path (located in ...\Documents\WinTAXWorkspace) by opening DATA page.
Proceed as follow:
• Start LynXLog software
• Open Data page by pressing Data button or click NavBar icon
• Click text below Base Directory field on the left and choose desired archiviation folder:

AN/FRQ panel can be opened by click once on Config Manager AN/FRQ label.
This panel allows to configure SL1 analogue and frequency inputs.
To configure a channel press EDIT button (or double click on channel label in Config manager
list): Channel Management Window will be displayed.

Channel Management Window allows to edit:
• Name: channel name.
• Log frq: logging frequency. If this parameters is None, the channel will not be logged and it will
not be available in analysis software*.
• Decimal Places: how many decimal places you wish to have.
• Unit: this parameter define measurement unit of the channel.
• Calibration Type : you can chose the type of channel calibration
• Calibration Value : you can insert calibration values
• Channel Description : you can insert a comment for the channel, it will displayed when mouse
hover channel name.
Configure as needed and update SL1 configuration if all
changes has be done.
