Hardware
Installation
The contents below specify the conditions to be ensured for the operation of ReXgen1.
GROUNDING
Since providing a common ground between nodes is not required, it is possible to have ground offsets between nodes. 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 minimize 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
CAN Bus and USB are not isolated; care must be taken when plugging the USB into the device. Removing the power supply when the device is interfaced with a PC via a Micro USB cable is advised.
Notes:
The CAN Bus Isolator and USB Isolators can beseparately.
Do not use the logger's USB port for data logging purposes, as it may result in damaging the USB port, and this won't be covered under warranty.
MOUNTING
Always mount the device in a way that minimises vibration exposure and accounts for the IP rating of the device. ReXgen1 is supplied with four screws to assist you with the mounting process.

CAN OVERVIEW
CAN stands for "Controller Area Network" and is defined in the ISO 11898 specification.
CAN BUS COMPONENTS
CAN Controller receives the transfer data from the microcomputer integrated into the control unit/device (also known as CAN Node). The CAN controller processes this data and relays it to the CAN transceiver. Also, the CAN controller receives data from the CAN transceiver, processes it, and relays it to the microcomputer integrated into the control unit/device (CAN Node).
CAN Transceiver is a transmitter and receiver in one. It converts the CAN controller's data into electrical signals and sends this data over the data bus lines. Also, it receives data and converts this data for the CAN controller.
CAN Data Bus Termination is a resistor (R) typically 120 ohms. It prevents data sent from being reflected at the ends and returning as an echo and ensures that the bus gets the correct DC levels.
MAXIMUM BUS SPEED & CABLE LENGTH
The CAN bus uses inexpensive twisted-pair wires to send data. All the nodes are connected to the same line (bus) with small branch lines. The signals on the two CAN lines have the same data sequence, but their amplitudes are opposite. So, if a pulse on the CAN-H line goes from 2.5V to 3.75V, then the corresponding pulse on the CAN-L line goes from 2.5V to 1.25V (opposite to CAN-H).
According to the standard, the maximum speed of a CAN bus is 1 Mbit/second. At a speed of 1 Mbit/s, a maximum cable length of about 40 meters (130 ft.) can be used. This is because the arbitration scheme requires that the wavefront of the signal can propagate to the most remote node and back again before the bit is sampled.
The maximum speed achievable is 1Mbps.
The maximum length achievable is 500 meters at a lower speed of 125 Kbps.
The bus should be terminated at both ends with 120-ohm resistance.
Removal of one node will not affect the communication in the bus.

Intended Use
The ReXgen2 is one of the most compact, pocket-sized data loggers suitable for automotive and various industrial applications. The device is designed to log data continuously for hours from a CAN bus and simultaneously save it to the embedded SD memory card. The device is tolerable in all harsh environments, requiring IP65 class protection. It can be easily mounted and integrated with your vehicle/machine.
Attention:
Do not use the logger's USB port for stand-alone data logging purposes, as it may damage the USB port, which won't be covered under warranty.
Hardware
INSTALLATION
The contents below specify the conditions to be ensured for the operation of ReXgen2.
GROUNDING
Since providing a common ground between nodes is not required, having ground offsets between nodes is possible. 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. Steps must be taken to eliminate ground offsets if the system is sensitive to emissions.
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 is also internally protected against low energy voltage events due to supply wire noise.
ISOLATION
Warning:
CAN Bus and USB are not isolated; care must be taken when plugging the USB into the device. Removing the power supply when the device is interfaced to a PC via USB is advised.
Do not use the logger's USB port for stand-alone data logging purposes, as it may damage the USB port, which won't be covered under warranty.
Note: CAN Bus Isolator and USB Isolator can be purchased separately.
MOUNTING
Warning: Always mount the device in a way that minimises vibration exposure and accounts for the IP rating of the device. ReXgen2 is supplied with four screws to assist you with the mounting process.
ANTENNA
An external active antenna with a supply voltage of 3V is required for GNSS data logging. Ensure that the antenna is connected correctly at all times and that it is not loose when the ReXgen2 is powered on. Operation with a loose antenna or without the antenna entirely can lead to GNSS data loss.
GNSS Antenna Connector
ReXgen2 uses an SMA female connector for the GNSS antenna.

CAN Overview
CAN is a "Controller Area Network, " defined in the ISO 11898 specification.
The Controller Area Network (CAN, also known as CAN Bus) is a vehicle bus standard designed to allow electronic control units and devices to communicate in applications without a host computer. As an alternative to conventional multi-wire looms, the CAN Bus allows various electronic components (such as electronic control units, micro-controllers, devices, sensors, actuators and other electronic components throughout the vehicle) to communicate on a single or dual-wire network data bus up to 1 Mbit/s.
CAN BUS COMPONENTS
CAN Controller receives the transfer data from the microcomputer integrated into the control unit/device (also known as CAN Node). The CAN controller processes this data and relays it to the CAN transceiver. Also, the CAN controller receives data from the CAN transceiver, processes it and relays it to the microcomputer integrated into the control unit/device (CAN Node).
CAN Transceiver is a transmitter and receiver in one. It converts the CAN controller's data into electrical signals and sends it over the data bus lines. Also, it receives data and converts this data for the CAN controller.
CAN Data Bus Termination is a resistor (R) typically of 120Ω. It prevents data sent from being reflected at the ends and returning as an echo, ensuring the bus gets the correct DC levels.
MAXIMUM BUS SPEED & CABLE LENGTH
The CAN bus uses inexpensive twisted pair wires to send data. All the nodes are connected to the same line (bus) with small branch lines. The signals on the two CAN lines have the same data sequence, but their amplitudes are opposite. So, if a pulse on the CAN-H line goes from 2.5V to 3.75V, the corresponding pulse on the CAN-L line goes from 2.5V to 1.25V (opposite to CAN-H).
According to the standard, the maximum speed of a CAN bus is 1 Mbit/second. At a speed of 1 Mbit/s, a maximum cable length of about 40 meters (130 ft.) can be used. This is because the arbitration scheme requires that the wavefront of the signal can propagate to the most remote node and back again before the bit is sampled.
• The maximum speed achievable is 1Mbps.
• The maximum length achievable is 500 metres at a lower speed of 125 Kbps.
• The bus should be terminated at both ends with 120-ohm resistance.
• Removal of one node will not affect the communication in the bus.

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
Warning:
CAN Bus and USB of the device are not isolated; care must be taken when plugging the USB into the device. Removing the device's power supply is advised when interfacing with a USB PC.
Notes:
CAN Bus Isolators and USB Isolators can bepurchased separately
Do not use the logger's USB port for stand-alone data logging, as it may damage the USB port, which won't be covered under warranty.
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.

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,
Notes:
Ensure that the device is placed in a manner that does not disturb the orientation of the IMU axis.
Or ensure the device's orientation is not disturbed for more than one axis when installing or operating.
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.

Functionality
Recording GNSS Data
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.
GNSS Orientation
The GNSS orientation requirements for installing ReXgen Air devices majorly focus on explaining orientations for:
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.
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.

Dead Reckoning
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.
