Annexures

This chapter contains technical data and certificates.

CAN OVERVIEW

CAN stands for "Controller Area Network" and is defined in the ISO 11898 specification.

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 the 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 Mbit/s, a maximum cable 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.

Hardware & Functionality

In this chapter, you will find Information on the device hardware and its functionality.

Hardware

INSTALLATION

The contents below specify the conditions to be ensured for the operation of ReXgen2.

GROUNDING

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.

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 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

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 separately.

MOUNTING

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.

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.

Enclosure & Cables

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.

CAN Overview

CAN is a "Controller Area Network, " 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 it 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 of 120Ω. It prevents data sent from being reflected at the ends and returning as an echo, ensuring the bus gets the 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, the corresponding pulse on the CAN-L line goes from 2.5V to 1.25V (opposite to CAN-H).

• The maximum speed achievable is 1Mbps.

• The maximum length achievable is 500 metres 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.

SAFETY INSTRUCTIONS

Ensure 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.
Do not use the logger's USB port for data logging purposes, as it may damage the USB port, which won't be covered under warranty.
