SAFETY INSTRUCTIONS
▪Always ensure that the device is installed, connected, and commissioned by a qualified professional
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 IP50.
▪Never immerse the device in water or other liquids.
▪The manufacturer must only repair the device.
▪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 the
user to configure ReXgen Air with custom baud rates and modify advanced bit timings.
ReXdesk also enables the user 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. This data can
be further transferred to the cloud using FTPs.
2.1.2 RECORDING LIN DATA
The device can effectively log data on field tests and the bench via LIN interfaces. Device
can work in Slave or Master mode. All logged data is saved to the eMMC.
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.

ReXgen Air: Product Manual
12 | P a g e © I n f l u x T e c h n o l o g y .
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.
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
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 ReXgen Air.
SIM CARD INSERTION
When inserting the sim card in a ReXgen Air device, ensure that you open the lid on the SIM
slot correctly and carefully. Mishandling the SIM slot lid can damage the device and further
damage the SIM card inside.
Also, ensure the SIM is inserted, as shown in the images above (Chip facing down).

ReXgen Air: Product Manual
13 | P a g e © I n f l u x T e c h n o l o g y .
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 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
also has internal protection against low energy voltage events due to supply wire noise.
ISOLATION
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 interfaced with a PC via
USB.
•CAN Bus and USB Isolators can be purchased seperately.
Notes
WARNING

ReXgen Air: Product Manual
14 | P a g e © I n f l u x T e c h n o l o g y .
MOUNTING
Always ensure to mount the device in a way that minimises vibration exposure and accounts for
the IP rating of the device. ReXgen 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.
2.2.2 ENCLOSURE
The device is not intended for use without the enclosure.
2.2.3 CABLES
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 external antenna to be purchased in addition along with the extension
cable. The price of the unit does not include the external antenna which can be purchased off
the shelf.
