Influx devices combine the 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, such as tunnels, urban canyons, or dense forests, and this is where dead reckoning steps in.

Using an accurately aligned IMU configuration, these devices help detect and plot navigation routes and patterns in areas with minimum GNSS coverage, such as tunnels, underground parking, subways, or other such areas.

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.

IMU Orientation

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.

INSTALLATION

The contents below specify the conditions to be ensured for the operation of ReXgen Air.

SIM CARD INSERTION

When inserting the SIM card in a ReXgen Air device, open the lid on the SIM slot correctly and carefully. Mishandling the SIM slot lid can damage the device and the SIM card inside.

Also, ensure the SIM is inserted, as shown in the images above (Chip facing down).

GROUNDING

Since it is not required to provide a common ground between nodes, it is possible to have ground offsets. Each node may observe different single-ended bus voltages (common mode bus voltages) while maintaining the same differential voltage. Operating a CAN system with large ground offsets can increase electromagnetic emissions. If the system is sensitive to emissions, steps must be taken to eliminate ground offsets.

TERMINATION

ISO-11898 requires that the CAN bus have a nominal characteristic line impedance of 120Ω. Therefore, the typical terminating resistor value for each bus end is 120Ω. Bus termination is used to minimise signal reflection on the bus.

SUPPLY VOLTAGE

It is always recommended to keep the nominal voltage within the specified rate. The device also has internal protection against low energy voltage events due to supply wire noise.

ISOLATION

MOUNTING

Always mount the device in a way that minimises vibration exposure and accounts for the IP rating of damage. Air is supplied with four screws to assist you with mounting.

ANTENNA

An external active FAKRA C or FAKRA D antenna with a supply voltage of 3V is required for GNSS and LTE data logging. It is to be ensured that the antenna is connected correctly (at all times) and that it is not loose when the ReXgen Air is powered on. Operation with a loose antenna or without the antenna entirely can lead to GNSS/LTE data loss.

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 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.

How to configure the ReXgen data logger to data (video tutorial).

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.

How to configure the ReXgen data logger to data (video tutorial).

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.

How to using ReXdesk.

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 ReXgen Air has an automotive-style 24-pin Molex Connector. (This enables the device to be easily and robustly installed in production machines). Molex 24 PIN to D Sub 25 connector can be purchased separately.

*ReXgen Air requires an external antenna to be purchased in addition to the extension cable. The unit's price does not include the external antenna, which can be purchased off the shelf.
