I. VINCILAB AT A GLANCE
1. Introduction
VinciLab is a modern and advanced mobile graphic data acquisition system, which can
be used in a variety of ways, standalone and with a computer and tablet, in the
classroom and in the field. It is a handheld Linux device equipped with two processors:
a main processor to control the device’s operating system and screen, and a
measurement processor to control the measurement and control processes. It has 8 GB
of internal memory 5.5 GB of which is available for user files.
VinciLab has a 5” capacitive color touch screen that provides a high-resolution display
(800 x 480 pixels) offering easy control of the device. For wireless connectivity VinciLab
is equipped with Wi-Fi and Bluetooth. The dedicated desktop applications, pre-installed
on VinciLab, offer tools for setting up the device, setting up wireless connections,
managing user files, browsing the web, watching video files, playing audio files, etc.
For connecting sensors VinciLab has four analog BT inputs, which allow very fast data
collection up to 1000000 samples per second, and two digital BT inputs for Motion
Detectors. It also has built-in a 3-axis accelerometer and a microphone. Additionally
VinciLab can output DC and AC voltage signals between -5 V and 5 V via the 3.5 mm
audio connector1.
The powerful Coach Application, pre-installed on VinciLab, offers live sensor data
displays, real-time graphing, tools for data processing and possibilities to create new or
open ready-to-go Coach activities enriched with texts, images and web-pages.
VinciLab can also be used as a lab interface connected (via USB or Wi-Fi) to computers
(Mac and Windows), tablets (iPad, Android) and Chromebooks. Coach 7 and Coach 7 Lite
programs and apps support such measurements.
By using wireless connectivity and the VNC protocol the Vinci-Lab’s screen can be
remotely viewed and controlled from any computer or mobile device connected to the
same network. VinciLab is delivered with:
• USB cable for connecting to the USB port or USB power adapter,

II. GETTING STARTED
1. Turning VinciLab On and Off
To turn VinciLab On
• Press the Power Button once.
• While VinciLab is booting the
message ‘VinciLab is starting. Please
wait.’ is displayed.
• Wait until the device finishes its
booting procedure and displays its
starting Home Screen as shown on
the image.
Note:
•
The minimum battery level to start VinciLab is 1%.
To turn VinciLab Off
• Tap
Shut Down in the status bar.
• On the new screen tap:
Shut Down to shut down VinciLab.
Reboot to restart VinciLab.
Screen Off to turn the screen off.
Pressing the Power button turns the screen on again.
Cancel to cancel the operation and return to the Home Screen.
Note:
•
Holding the Power button for about 8 seconds causes VinciLab to shut down. Use this
possibility only in case of emergency when your VinciLab does not respond anymore.
2. Powering VinciLab
An internal rechargeable battery (Li-Poly 3.7 V, 4000 mAh, located in the back
compartment), powers VinciLab. The battery icon on the status bar of the Home Screen
indicates the current power level.
VinciLab is delivered with its battery partially charged. The device will work as long as
the battery provides power or it is powered via the power adapter. Before the battery
becomes too low for operating the device a warning will appear on the screen. If you
continue working without charging, the device will shut down. A fully discharged battery
requires up to 8 hours of charge time.
8 | VinciLab User’s Guide
To charge battery
Only use the USB cable and USB power adapter delivered with your VinciLab.
• Connect the USB cable to the mini USB port of VinciLab.
• Connect the other end of the USB cable to the USB power adapter.
• Plug the USB power adapter into a standard power outlet.
- or • Connect the USB cable to the mini USB port of VinciLab.
• Connect the other end of the USB cable into a USB port of your computer. Notice,
that the efficiency of charging via a USB port, is limited by the maximal current
provided by a USB socket (500 mA for USB 2.0 and 800 mA for USB 3.0).
Battery life will depend on the screen brightness and on the sensors and features used,
but typically you can expect to use VinciLab at least 4 hours without recharging it. To
save power dim the brightness of the screen or turn off the screen when you do not
need it. See also III. VinciLab Applications, 3. Settings.
The long-time life of the battery is more than 300 full (0 to 100%) charging cycles. If
charging cycle is not full e.g. 30% to 60% it will last more charging cycles. Exposure to
temperature over 35oC will significantly reduce battery life. A replacement battery can
be ordered separately (CMA art. code 001bat).
Notes:
•
•
•
•
•
VinciLab can be used while the battery is being charged by the power adapter.
VinciLab typically consumes about 450 mA. If you run some videos, set the screen brightness
to the maximum level, do a lot of data transferring via Wi-Fi, connect many sensors and
external USB devices then power consumption will be much higher.
When the USB port does not provide enough power, VinciLab will not be charged or charging
will be significantly slower.
On most computers USB ports do not provide enough power for simultaneous operating of
VinciLab and charging its battery.
When VinciLab discharges fully it will not turn on until a minimum charge of 1% is reached.
3. Home Screen
The Home Screen is the starting point for using your VinciLab and provides shortcuts to
applications. The status bar is always present at the bottom of the Home screen and

4. Sensor inputs
4.1 Analog sensor inputs
VinciLab has four analog BT (right-handed) sensor inputs A1, A2, A3, A4 with a maximum
sampling rate of 1 MHz (four inputs simultaneously). CMA BT sensors2 (with exception
of the CMA digital Motion Detector) can be directly connected to the analog sensor
inputs.
All analog inputs can be (simultaneously) used as counter inputs. Sensors such as the
CMA Photogate (art. code 0662i or BT633i) or CMA Radiation sensor (art. code 0666i or
BT70i) are by default defined as counters. Other analog sensors can be used as counters
after defining the counter conversion settings in Coach e.g. defining a heartbeat sensor
to count heartbeats.
2
Analog Vernier BT sensors can be directly connected to VinciLab as well. Older (4-mm) versions of CMA sensors
can be connected via a 4mm to BT adapter (art. code 0519).
VinciLab User’s Guide | 11
4.2. Digital sensor inputs
VinciLab has two digital BT (left-hand) sensor inputs D1 and D2. The CMA BT digital
Motion Detectors can be directly connected to these sensor inputs.
4.3. Sensor detection
VinciLab supports sensor recognition and tries to identify sensors connected to inputs.
• When Coach identifies the connected sensor then its name is automatically
displayed in the Activity Screen tree and its digital display appears on the Sensors
Screen. When the sensor is then disconnected its name and digital display disappear
automatically.
• When Coach does not identify the connected sensor then its name and digital
display does not appear. This happens for some older CMA sensors or sensors
connected via the CMA 4-mm to BT adapter art. code 0519. The user has to manually
choose and select the correct sensor from Coach Sensor Library. This is done via the
option Sensor Settings available in the Tool menu of the Sensors Screen. When the
sensor is disconnected then Coach keeps displaying the sensor name and its digital
display. The sensor can be removed by selecting the option None or selecting another
sensor from the Sensor Library.
• When a predefined sensor is already set up in an Activity/Result and Coach:
- identifies the connected sensor as a different sensor then the sensor name
becomes red, tap Exchange to change the sensor to the connected one.
- does not identify it then its name remains grey, tap Confirm to accept the predefined sensor or tap Clear to remove the connection.
See also ‘IV. Coach Application, 5. Sensors Screens’.
5. Built-in sensors
VinciLab is equipped with two internal sensors:
• A Microphone, which measures sound waveforms. This sensor can be used as:
- a single sensor, this is possible only when working with a Coach Result for Sound
only, or a Coach Activity for the Internal microphone.
- in combination with other sensors, the sound sensor will be then connected for
measurements via input A2. To make the sensor ready for measurement open
the Sensor Settings dialog and tap the Enabled Internal sensor button. When the
sensor is enabled no other measurements can be done via input A2 even if there
is a sensor connected to this input.
If an external microphone is connected via Audio In port then the internal
microphone is disconnected and the external microphone is used instead.
• A 3-axis Accelerometer, which measures acceleration in 3 ranges: ± 20 m/s2,
± 40 m/s2 and ± 80 m/s2 in the x, y and z directions. This sensor can be used in
combination with other external sensors.
To make the sensor ready for measurement tap X, Y or Z tab in the Sensor Settings
and tap the checkbox Enabled. The X, Y, Z tabs are used for the acceleration
components respectively in x, y and z direction.
See also ‘IV. Coach Application, 5.1. Sensor Settings’.
12 | VinciLab User’s Guide
For the directions of x, y and z axes of
the accelerometer see the image.
Holding the VinciLab in the shown
position should give the following
values of the component accelerations:
x-component ≈ 0 m/s2
y-component ≈ 0 m/s2
z-component ≈ -9.81 m/s2.
6. Signal generator
Via the 3.5 mm Audio Out port VinciLab outputs DC and AC voltage signals between -5V
and 5V. This functionality is present only on VinciLabs sold starting from February 2019
(the Audio Out port of these models has a blue connector). There are two channels
available3.

• Tap Choose or tap None.
• Tap the name of the desired sensor
to select it and confirm with
.
C. Own sensors
Users can create their own sensors and
add them for use in Coach. Since analog
inputs of VinciLab measure voltage
signals in two ranges, between 0 .. 5 V
or -10 .. 10 V, it is important to indicate
which voltage range is used by a new
sensor.
• Tap Create New.
• Select the voltage range of your
new sensor.
• By default the sensor settings are filled like for a Voltage sensor. Enter the
sensor information adequate to your sensor.
• Perform the sensor calibration by providing a function or by typing/measuring
the calibration points in the same way as described for the standard calibration.
See below 5.2. Sensor Calibration.
• Tap
to save the new sensor. If you save it in the User Library then it will be
available globally and you can use it in any Coach Activity.
• To remove the user sensor tap Delete sensor.
D. Built-in sensors
In the Sensor Settings dialog you can
also enable and disable the internal
sensors.
Internal accelerometer
The X, Y, Z tabs in this dialog are used
for the acceleration components
respectively in x, y and y direction. Tap
VinciLab User’s Guide | 29
X, Y, or Z and tap the checkbox Enabled to make the sensor ready for measurement.
Internal microphone
Tab A2 has additional button Enable Internal microphone, which switches this
output to measure via the Internal microphone. This allows using internal
microphone with combination with other sensors.6
The Activity Sound only allows to measure only with the internal microphone. It has
only tab Internal, which displays settings of the internal microphone.
Note that if an external microphone is connected via Audio In port then the internal
microphone is disconnected and the external microphone is used instead.
Options of the Sensor Settings dialog:
Sensor: displays the sensor’s name, number and brand.
Range: displays the sensor range, for sensors with the EEPROM memory this is the
range stored in the EEPROM (selected by default). Most sensors have more
measurement ranges.
• Tap a measurement range to choose another
range. The calibration stored in the sensor’s
memory is indicated by ‘EEPROM’.
Use as: displays the mode in which the sensor
works. Most sensors are used by default in the
Analog mode.
• Tap the selected mode to choose another mode.
• Specify the conversion settings for Counter,
Digital sensor (1-bit), Frequency meter and Time-interval meter.
Use Set to zero or Set to value to shift the provided sensor calibration. Use Reset to
reset the Set to … operation.
Use the Calibrate button to open the calibration, which belongs to the current selected
range and modify it if needed. The new calibration can be added as a new range or
when the EEPROM range is selected can be stored in the sensor’s memory.
Use Replace to choose another sensor from the Sensor Library and replace the
currently selected sensor. This action can be performed even when the automatically
identified sensor is selected, then its settings are overruled by settings of the new
selected sensor. Use Remove to remove such sensor from the input.
5.2. Sensor calibration
Most CMA sensors do not need to be calibrated. Their calibrations are provided by the
sensors themselves (stored in the sensor's EEPROM memory) and by the Coach software
(included in the CMA Sensor Library). For even better accuracy these calibrations can be
improved or new calibrations can be made and added as new sensor input ranges.
The sensor calibration in Coach provides the sensor name, its measurement range and
6
Only for VinciLab’s purchased starting from February 2019
30 | VinciLab User’s Guide
the mathematical relation between the voltage values produced by the sensor (in most
cases) and the values of the physical quantity measured. There are two ways to perform
a calibration:
• By providing a calibration function: method Function.
• By providing calibration points in the calibration table: method Points (not possible
for the EEPROM memory). These points can be:
- measured, the sensor voltage value is measured and the value of the
corresponding quantity is typed. In this case the sensor has to be connected to
the active interface. Such a calibration is the most accurate calibration.
- Keyed in, both the sensor voltage value and the value of the corresponding
quantity are typed.
The best function fit, through the calibration points, is calculated according to the
least-squares method.
The calibration function will be then extrapolated to cover the whole range.
For sensors equipped with EEPROM memory it is also possible to replace the factory
calibration by a new calibration. This allows making an accurate calibration per physical
sensor. Next time such a sensor will be connected and detected its new calibration will
be used.
To add a new calibration (range) for a predefined sensor
• Connect a sensor or choose a sensor from the CMA Library.
• Select a range from the CMA Library but NOT EEPROM and User range.
• Tap Calibrate. The Calibration opens and shows the sensor name, calibration settings
and the calibration graph.
• In the Range ID enter the range name.
• Select the calibration method: Function
or Points. When the method Points is
selected the tab Points with the
calibration table is added.
• If desired change: Quantity, Unit,
Minimum and Maximum.
• Select the desired function-fit type.
• Perform the calibration. Key in the function coefficients (Function) or fill the
calibration table by adding calibration points (Points).
• Tap
to save the new range. If you save it in the User Library then it will be
available globally and you can use it in any Coach Activity.
• Use the Delete range button In the Sensor Settings dialog to remove a user range.
To replace the calibration in the sensor’s EEPROM memory
• Connect a sensor equipped with EEPROM memory.
• Check if the range is set to EEPROM, if not tap the range and select the EEPROM
range (the word EEPROM is displayed in brackets).
• Tap Calibrate.
• Key in new coefficients and if needed a new unit. The calibration graph will be
VinciLab User’s Guide | 31
adjusted accordingly. It is not possible to edit quantity, minimum and maximum of
the sensor range and function type. This is because the EEPROM calibration has a
specific (fixed) format.
• You may use the
Get from
Library button to load an existing
calibration from CMA Sensor Library.
• Tap
to store the new calibration in
the sensor memory. Tap OK to accept.
The new calibration replaces the old
EEPROM calibration.
• Use the Reset Calibration to Factory
button to restore the original EEPROM
calibration.
To edit a self-defined sensor
• Choose a self-defined sensor from the User Library.
• Tap Edit. The Calibration dialog opens and shows the sensor name, calibration
settings and the calibration graph. If desired modify the calibration settings.
• Tap
to accept. The sensor can be overwritten or added as a new self-defined
sensor.
5.3. Measurement Settings
The Measurement Settings dialog specifies
how VinciLab has to measure. Select the
measurement type (time-based, event-based
or manual) and set the respective
measurement settings. If you want to start
your measurement automatically enable
triggering and define trigger conditions in the
Triggering tab. In the Advanced tab it is
possible to repeat the measurement process
a number of times.
6. Diagrams Screen
The Diagrams Screen is used to display measured or calculated data in diagrams. Here
you can also adjust graph settings, create new diagrams and perform data processing
and analysis.
A standard diagram, the sensor quantity
vs the clock (time), is created
automatically after a sensor has been
identified or selected from the Sensor
Library. Changing of any diagram style
options, such as removing the grid or
changing the diagram color, removes
32 | VinciLab User’s Guide
the suffix ‘(Standard)’ from the diagram’s name and makes it a user-defined diagram.
On starting a measurement graph(s) are drawn in pre-defined diagrams. Notice that
when starting a new measurement run, the existing data is overwritten by the new data
without warning. You can collect several measurement runs for comparison by using the
Copy column option from the Tool menu.

V. USING VINCILAB WITH A COMPUTER AND A TABLET
1. Connecting VinciLab via the USB cable
Before you start using VinciLab with a computer via the USB cable we recommend to
first install the latest version of the Coach 7 or Coach 7 Lite software on your computer.
In most cases the VinciLab installation is automatically executed the first time VinciLab is
connected to the USB port of the computer. After successful installation VinciLab is
shown under Network adapters (Windows)/Ethernet cards (MAC).
Windows Device Manager
Mac System Information
If the installation process is not successfully performed in Windows (VinciLab is marked
by yellow exclamation sign) then the driver has to be installed manually.
• Go to Control Panel and start Windows Device Manager.
• Under network adapters right-click VinciLab and select Update Driver Software.
• Select Browse my computer for driver software.
• Browse to Program Files (x86)\CMA\Coach7\Common\EthernetCableDriver
location7.
• Click Next. The driver software will be installed. After successful installation the
message Device driver software installed successfully will appear.
2. Problems communicating with VinciLab
If after correct installation of VinciLab on your computer you experience problems with
communication between VinciLab and computer and the Coach 7 program there can be
a couple reasons for this.
1. A computer firewall may cause communication problems (as well via USB as via WiFi). Make sure that the Coach executable (Coach7.exe) has permission to use the IPaddress of VinciLab, and ports 22 and 1111 – 1116 are opened. If connected through
USB, the VinciLab gets an IP-address in the range 169.254.200.1 – 169.254.200.255.
For a wireless connection, the address depends on your network configuration.
Please note that when using the USB cable, it may take a while before VinciLab gets
its final IP-address.
2. An anti-virus program can block communication between Coach 7 and VinciLab.
7
During the Coach installation the USB VinciLab driver setup files are copied to your computer.
44 | VinciLab User’s Guide
Give Coach (Coach7.exe) permission for such communication.
3. VinciLab makes use of Microsoft RNDIS drivers, some older versions of the RNDIS
software may give problems on Windows computers. There is a hotfix available at:
http://support.microsoft.com/kb/2477042) for Windows 7, Vista Windows Server
2008 R2, Windows Vista or Windows Server 2008. After installation of the hotfix use
the Device Manager to uninstall the VinciLab driver while VinciLab remains

remove the predefined folders ‘Coach’ and ‘Media’. Removing these folders may cause
some of VinciLab applications to not work properly.
4. Using VinciLab for data collection with computers and tablets
Coach 7 and Coach 7 Litel for both desktops and tablets support measurements with
VinciLab. During such measurement VinciLab stays connected to the computer/tablet
via a USB cable or communicates wirelessly
via Wi-Fi. The collected data are transferred
in real-time to the computer/tablet and the
course of the measurement can be followed
directly on the computer/tablet screen. The
VinciLab screen is inactive and displays the
image shown here. The recorded data are not
stored in the VinciLab’s memory and should
be saved in the Coach 7 program.
4.1. Communication with Coach 7
The Coach 7 program running on the computer/tablet can communicate with VinciLab
via:
• the USB port when VinciLab is connected via the provided USB cable (not possible
for iPad, Chromebook and some Android tablets), or
• via Wi-Fi when devices are in the same network.
To select the connection for VinciLab communication
• Start Coach 7 or Coach 7 Lite.
• Click
or select the menu option Tools >
Hardware Settings (Author mode only).
• In the Hardware Settings dialog click VinciLab.
By default the connection is set to USB. To

Activity/Result (Author mode only).
• Connect sensor(s) to the sensor input(s) on VinciLab.
• VinciLab automatically detects the connected sensor(s) and displays the sensor icons
of the identified sensors on the VinciLab screen panel. The sensors, which are not
automatically identified, have to be selected from the Coach Sensor Library.
• The measurement is executed according to the given measurement settings. Click
to check these settings: measurement type, measuring time, sampling frequency
and number of collected samples. Notice that the max. sampling frequency is 1 MHz
and the max. number of collected measurement points is 500 000 per input.
• Follow the instructions in the Activity or directly start the measurement by clicking
the Start button .
- In most cases, Coach automatically starts the measurement.
- If triggering is enabled then the measurement is started automatically when the
trigger conditions are met.
- When the type of measurement is set to Manual then the Manual Start button
appears in the Toolbar. Click this button to collect a single measurement.
When keyboard input(s) is specified then the value of one or more quantities
have to be typed in.

cma7/cmr7 format.
WARNING! Coach on VinciLab does not read cma7/cmr7 files. If you want to use your
Activity/Result on VinciLab you have to save the file via the menu option Save for
MoLab/VinciLab.
4.3. Activities for VinciLab
The Coach 7 program or Coach 7 App offers more features than the Coach Application
on VinciLab. One of the most important is the Author mode with the possibility of
creating Coach Activities and Results for VinciLab. Such Activities (*.cma files) and
Results (cmr.* files) can be copied to the VinciLab folder ‘My Files/Coach’ or a USB flash
memory and opened in the Coach Application on VinciLab.
Any features in the Activities/Results not existing in the Coach Application, such as
images embedded in texts, videos, diagram annotations, etc., will be ignored when
opened on VinciLab and will be not shown. Tutorials and examples of Activities are
available as well in the Coach Application as in the Coach 7 program.
5. Displaying VinciLab’s screen on a computer or a mobile device
VinciLab offers Data Share via Virtual Network Computing (VNC) which makes it possible
to monitor the VinciLab screen and to control VinciLab from any computer or a mobile
device, such as an iPad, an Android tablet, Chromebook, or a smart phone, connected to
the same network as VinciLab. The VNC protocol can run via a network connection but
also via a USB connection.
