The device can effectively log data on field tests and a bench via CANinterfaces. The device supports all standard CAN baud rates. ReXdesk software allows users to configure ReXgen Air with custom baud rates and modify advanced bit timings. ReXdesk also enables users to configure ReXgen Air with CAN & J1939 filters. All logged data is saved to the secure embedded memory. The user can configure triggers based on CAN IDs, parameter values & J1939 DM1 messages to start or stop logging.

The device can effectively log data on field tests and the bench via LIN interfaces. The device can work in Slave or Master mode. All logged data is saved to the eMMC.
The device consists of an internal GNSS module and an external active antenna with a supply voltage of 3V. This receiver can evaluate signals from the GNSS/QZSS, GLONASS, BeiDou and Galileo satellites. GNNS data can be logged at sampling rates up to 30HZ.
The GNSS orientation requirements for installing ReXgen Air devices majorly focus on explaining orientations for:

Influx devices combine Global Navigation Satellite System (GNSS) and dead reckoning for optimal navigation and location accuracy. While GNSS provides precise positioning under ideal conditions, its signal can be weakened or lost in certain environments like tunnels, urban canyons, or dense forests.b This is where dead reckoning steps in.
Using accurately aligned IMU configuration, these devices help detect and plot navigation routes and patterns in areas such as tunnels, underground parking, subways, or any area with minimum GNSS coverage.
Dead reckoning continuously estimates your position based on your device's movement data, such as speed and direction. When GNSS signals are unavailable, dead reckoning takes over, ensuring uninterrupted navigation until the GNSS connection is restored.
Using the Geofencing option, one can define up to one circular geofencing area, creating a circular area or fence around the location of interest.
Radius: specify the radius to adjust the location's proximity in meters.
Latitude: specify the latitudinal location.
Longitude: specify the longitudinal location.
The module draws a circle using the values specified for the Longitude, Latitude and radius.

The device consists of an internal accelerometer and gyroscope module. The acceleration output data rate is up to 6664 Hz with a vibration rate of ±2/±4/±8/±16 g at full scale. The angular output data rate of the gyroscope is up to 1666 Hz with ±125/±250/±500/±1000/±2000 dps at full scale.

Align the IMU of the device to obtain the correct measurements, as shown below:
Place the device into the vehicle so that the IMU chip inside is aligned with the axis,
In case of misalignment, align the 'Z' axis first, followed by 'Y' and then 'X'. The chart below explains the attributes of all three axes in detail:
To Calculate the exact angle in case of misalignment:
Keep the axis's actual position in mind- measure the angle of misalignment.
Subtract the current measured angle from the actual angle value.
For example, if the vehicle's attitude is misaligned at its roll, the axes Z and Y are misaligned.

Similarly, if the vehicle's attitude is misaligned at its yaw, the axes X and Y are misaligned.
Similarly, if the vehicle's attitude is misaligned at its pitch, the axes Z and X are misaligned.
For instance, the input function can log status information from devices, machines, and sensors to directly determine and monitor switch and key states. You can record the data determined from the input functions, which can be used to create triggers for starting and stopping logging.
