There can be a couple of reasons why Coach fails to communicate with VinciLab:

  • The VinciLab driver is not installed correctly on your computer. After a successful installation, VinciLab should be visible in the Windows Device Manager under Network adapters. If the driver wasn’t successfully installed, it can be installed manually in Device Manager by specifying the USB VinciLab driver setup files. Details of this procedure can be found in the VinciLab Users’ Guide.
  • The USB cable is not connected correctly. You have to connect the provided USB cable correctly and use the USB connector that is meant for communication, and not the USB connector meant for additional powering.
  • A computer firewall may cause communication problems (via USB or Wi-Fi). Make sure that the Coach executable (Coach32.exe in Coach 6, Coach7.exe in Coach 7) has permission to use the ip-address of VinciLab, and ports 22 and 1111 – 1116 are opened. If connected through USB, the VinciLab gets an ip-address in the range – 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.
  • Some anti-virus programs can block communication between Coach and VinciLab. Give Coach permission for such communication.

In general: if an attempt to connect VinciLab in Coach fails and you change the hardware settings in Coach, restart VinciLab and try again to connect.

There appears to be a problem with some (newer) sensors where the EEPROM cannot be read properly by the CLAB. A solution for this hardware problem is yet unknown. At the moment we advise you to manually select unrecognized sensors from the sensor library.

The €Lab interface is only powered through USB, which places a limitation to the maximum power consumption. This may also be dependent on the computer the interface is connected to. Some sensors needs more power (for example the Force sensor or the CO2 sensor) and when such a sensor is connected to €Lab and the USB port does not provide enough power then the sensor may not work properly or may not be automatically recognised by the Coach software. First select manually the sensor from the Coach Sensor Library and check if this solves the problem.



There is a hotfix available for Windows 7, Vista Windows Server 2008 R2, Windows Vista or Windows Server 2008, and a separate hotfix for Windows XP.
After installation of the hotfix use the Device Manager to uninstall the VinciLab driver while VinciLab remains connected to the computer via the USB cable. Then disconnect the USB cable from the computer and connect it again to use the new Microsoft RNDIS driver.

Wireless measurement is possible with the VinciLab and CLAB interfaces. The VinciLab is an independent datalogger that can be connected to a computer and Coach to exchange data. The CLAB is a datalogger to which a measurement program can be uploaded via Coach. The measurement itself can be carried out wirelessly and the data can be transferred to Coach at a later time.
In addition, a wireless interface is being developed that uses Bluetooth to communicate with a computer / mobile device (within a 10 meter range).
