SAFETY INSTRUCTIONS
▪Always ensure that the device is installed, connected, and commissioned by a qualified professional by
following all safety norms.
▪Disconnect the device completely before handling it and disconnect any independently supplied output load
circuits.
▪Do not connect the housing to Ground externally. This will suspend the reverse voltage protection of the
power supply. Applying a reverse voltage in this case will destroy the supply circuits.
▪Provide all the device connectors with plugs and any protection caps required to ensure protection class
IP65.
▪Never immerse the device in water or other liquids.
▪The device must only be repaired by the manufacturer.
▪Keep substances that contain solvents away from the type label.

Table 1: Device Functions
2.1.1 RECORDING CAN/CAN FD DATA
The device can be effectively used to log data on field tests as well as on a bench via CAN/CAN FD
interfaces. The device supports all standard CAN/CAN FD baud rates. ReXdesk software also allows
the user to configure ReXgen with custom baud rates and modify advanced bit timings. ReXdesk
also allows the user to configure ReXgen 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.
2.1.2 RECORDING LIN DATA
The device can be effectively used to log data on field tests as well as on bench via LIN interfaces.
All logged data is saved to the embedded SD memory card.
2.1.3 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 18HZ.
*Applicable only for ReXgen2 IMU version
2.1.4 RECORDING ACCELEROMETER & GYROSCOPE DATA
The device consists of an internal accelerometer and gyroscope module. Acceleration output data
rate is up to 6664 Hz with vibration rate of ±2/±4/±8/±16 g at full scale. Angular output data rate of
gyroscope is up to 1666 Hz with ±125/±250/±500/±1000/±2000 dps at full scale.
*Applicable only for ReXgen2 IMU version
2.1.5 DIGITAL & ANALOG INPUT FUNCTIONS
The input function can be used, for instance, to log status information from devices, machines, and
sensors to directly determine and monitor switch and key states. You can record the data

© 2020 Influx Technology | Version 1.2
determined from the input functions, and it can be used for creating triggers for starting and
stopping logging.
2.2 HARDWARE
2.2.1 INSTALLATION
The contents below specify the conditions to be ensured for the operation of ReXgen2.
GROUNDING
Since it is not required to provide a common ground between nodes, it is possible to have ground
offsets between nodes. That is, 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 lead to increased 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 end of the bus 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, that may occur as a result of supply wire
noise.
ISOLATION
CAN Bus and USB of the device is not isolated; care must be taken when plugging the USB to the
device. It is advised to remove the power supply to the device when the device is interfaced to a PC
via USB.
MOUNTING
Always ensure to mount the device in a way that minimizes vibration exposure and accounts for the IP
rating of the device. ReXgen is supplied with 4 screws to assist you with the mounting process.
•CAN Bus and USB Isolators can be purchased seperately.
Notes
WARNING

© 2020 Influx Technology | Version 1.2
ANTENNA
An external active antenna with a supply voltage of 3V is required for GNSS data logging. It is to be
ensured that the antenna is properly connected at all times and that it is not loose when the ReXgen
is powered on. Operation with a loose antenna or without the antenna entirely can lead to GNSS
data loss.
2.2.2 ENCLOSURE
The device is not intended for use without the enclosure.
2.2.3 CABLES
ReXgen comes with integrated cables, with a 9-pin D-Type connector. ReXgen is also available with
Rugged Automotive specification connectors; these are made as per request on bulk orders. Apart
from this the device will be supplied with a micro-USB cable and a GNSS antenna with an integrated
5M cable (INF2112/2113).
