SAFETY INSTRUCTIONS
▪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 IP65.
▪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 DATA
The device can effectively field log data on tests and a bench via the 1xCAN interface. The device
supports all standard CAN baud rates. ReXdesk software allows users to configure ReXgen1 with
custom baud rates and modify advanced bit timings. ReXdesk also allows the user to configure
ReXgen1 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 Functioning as a PASS-THRU device using J2534:
ReXgen1 is designed to function not just as a data logging device but also as a capable pass-thru
device. The communication protocols supported by ReXgen1 as a J2534 tool are; ISO14229,
ISO14230, CAN (ISO11898), ISO15765, and J1939.
It allows the users to connect to the vehicle CAN Bus using the Pass-Thru API (Application
Program Interface), enabling you to create programs that accomplish your vehicle
communication needs. The pass-thru feature is already supported by Influx Module Analyser,
SavvyCAN and K-Cal Software.
2.2 HARDWARE
2.2.1 INSTALLATION
The contents below specify the conditions to be ensured for the operation of ReXgen1.
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 increase electromagnetic emissions. If the system is sensitive to
emissions, steps must be taken to eliminate ground offsets.

ReXgen 1: Product Manual
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
isused 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
hasinternal 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 to a PC via a Micro USB cable is
advised.
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.

The device is not intended for use without the enclosure.

4ANNEXURES
This chapter contains technical data and certificates.
4.1 CAN OVERVIEW
CAN stands for "Controller Area Network" and is 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 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 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

ReXgen 1: Product Manual
Mbit/s, a maximumcable 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.
