Warning:
Do not use the logger's USB port for stand-alone data logging purposes, as it may damage the USB port, which won't be covered under warranty.
The device is not intended for use without the enclosure.
ReXgen2 comes with integrated cables with a 9-pin D-Type connector. ReXgen2 is also available with Rugged Automotive specification connectors, made per bulk order requests. The device will have a micro-USB cable and a GNSS antenna with an integrated 5M cable (INF2112.02/03).
The contents below specify the conditions to be ensured for the operation of ReXgen2.
Since providing a common ground between nodes is not required, having ground offsets between nodes is possible. 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. Steps must be taken to eliminate ground offsets if the system is sensitive to emissions.
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 minimise signal reflection on the bus.
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.
Warning:
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.
Do not use the logger's USB port for stand-alone data logging purposes, as it may damage the USB port, which won't be covered under warranty.
Note: CAN Bus Isolator and USB Isolator can be purchased separately.
Warning: 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.
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.
There are two connectors, a male and female 9-pin Standard D-Type connector.
Channel 0 Connector
Channel 1 Connector
Notes:
The connector needs to be tightened properly to make a proper connection, ensuring reliable operation.
Each CAN/CAN FD bus end must be terminated with a 120Ω resistor across CAN H & CAN L.
Do not short-circuit any pins.
The maximum safe applied voltage for analog and digital I/P is ± 28 V.
Do not use the logger's USB port for stand-alone data logging purposes, as it may damage the USB port, which won't be covered under warranty.
