switch and key states. The data determined from the input/
output functions can be visualized or forwarded via the
CAN bus.
3.1.4 Acceleration sensor
The acceleration sensor registers and evaluates
accelerations in the X, Y, and Z axes, and sends them via the
CAN bus.

3.1.5 Gyro sensor
The 3-axis gyro sensor registers and evaluates the angle
speeds in the X, Y, and Z axes and sends them to the
CAN bus.

3.1.6 GNSS (Global Navigation Satellite System)
The device features a GNSS receiver. You can send the
position data determined by the GNSS receiver via the CAN
bus or the mobile radio network. The receiver can process
signals from GPS, GLONASS, and BeiDou satellites. It can
process data from two navigation systems simultaneously.
This increases the accuracy.
3.1.7 eSIM card
The device features an integrated eSIM card. On delivery,
the eSIM card already has an eSIM profile with all the
necessary communication settings.
INFORMATION
On delivery, the device’s eSIM card is not yet enabled. After
registration of the TFX, enabling the eSIM card can take up
to 1 working day.
3.2 Connectors
The device features the following connectors:
> 1 main plug connector (14-pin): CAN1 / VCC / GND /
AIN1-3 / DOUT
> 1 GNSS antenna port, FAKRA, C-coded in blue (models
TFX External Antenna)
> 1 mobile radio antenna port, FAKRA, D-coded in violet
(model TFX External Antenna)
> 1 micro-USB port, type AB
3.2.1 Main plug connector
Use the main plug connector to connect the device to
the CAN bus and supply it with power. The I/O signals are
integrated in the plug connector.
