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 be purchased separately.
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.

Enclosure

Warning: The device is not intended for use without the enclosure.

LED

Pinout

ReXgen1 comes with an integrated cable with a 9-pin D-Type connector.

PIN DETAILS: 9-pin Standard D-Type connector.

Connector

Notes:

The connector needs to be tightened properly to make a proper connection, ensuring reliable operation.
Each end of the CAN bus must be terminated with a 120Ω resistor across CAN H & CAN L.
Do not short-circuit any pins.
Do not use the logger's USB port for data logging, as it may damage the USB port, which won't be covered under warranty.

Note:

Pins not mentioned in the description table(s) are NC.

Functions

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 enables 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.

Functioning as a PASS-THRU device using J2534:

ReXgen1 is designed to function as a data logging device and 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. Influx Module Analyser, SavvyCAN and K-Cal Software already support the pass-thru feature.
