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 the 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.
The following formatting and symbols will help you recognise the purpose of each paragraph:

Table 1: Device Functions
2.1.1 RECORDING CAN/CAN FD DATA
The device can effectively log data on field tests and a bench via CAN/CAN FD interfaces.
The device supports all standard CAN/CAN FD baud rates. ReXdesk software allows users
to configure ReXgen2 with custom baud rates and modify advanced bit timings. ReXdesk
also allows the user to configure ReXgen2 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 and 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 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.
*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 determine and monitor switch and key states directly. You can

ReXgen 2: Product Manual
12 | P a g e © I n f l u x T e c h n o l o g y .
record the data 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. 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 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
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.
•CAN Bus and USB Isolators can be purchased seperately.
Notes
WARNING

ReXgen 2: Product Manual
13 | P a g e © I n f l u x T e c h n o l o g y .
MOUNTING
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.
2.2.2 ENCLOSURE
The device is not intended for use without the enclosure.
2.2.3 CABLES
ReXgen2 comes with integrated cables with a 9-pin D-Type connector. ReXgen2 is also
available with Rugged Automotive specification connectors, made per bulk orders request.
The device will be supplied with a micro-USB cable and a GNSS antenna with an integrated
5M cable (INF2112/2113).
