Introduction

1 Introduction

By purchasing the IXXAT USB-to-CANV2 interface, you decided for a high-

quality electronic component developed and manufactured according to the

latest technological standards.

This manual describes the USB-to-CANV2 compact, USB-to-CANV2 embedded,

USB-to-CANV2 professional as well as the USB-to-CANV2 automotive CAN in-

terface.

In the further description these interfaces are referred as CAN-interface.

The properties of the CAN interfaces are:

USB-to-CANV2 compact / embedded

USB 2.0 Hi-Speed (480MBit/s)

one CAN-High-Speed channel according ISO11898-2

optional galvanic CAN bus isolation

fieldbus connection:

ocompact: Sub-D9M or RJ45

oembedded: Sub-D9M

USB-to-CAN V2 professional

USB 2.0 Hi-Speed (480MBit/s)

two CAN-High-Speed channels according ISO11898-2

galvanic CAN bus isolation (both CAN channels are on the same potential)

fieldbus connection: 2 x RJ45

equipped with two cable adapter RJ45 to Sub-D9M

USB-to-CAN V2 automotive

USB 2.0 Hi-Speed (480MBit/s)

two CAN-High-Speed channels according ISO11898-2, CAN1 can be

switched between high- and low-speed (ISO 11898-3) via software.

one LIN-Interface V1.3, Master/Slave-Mode switchable via software.

Please refer to the instructions in chapter 4.2

galvanic fieldbus isolation (all field bus channels are on the same potential)

fieldbus connection: 2 x RJ45

equipped with two cable adapter RJ45 to Sub-D9M

Installation

2 Installation

2.1 Software installation

To operate the interface a driver has to be installed first. For Windows this

driver is part of the VCI (Virtual CAN Interface) V3, which can be downloaded

for free on the IXXAT webpage http://www.ixxat.com.

For installation of the VCI V3 driver on Windows comuters, please refer to the

VCI installation manual.

IXXAT also offers the ECI driver for Linux and real-time operating systems for

many CAN interfaces. Information on supported operating systems and inter-

faces is available on the IXXAT webpage http://www.ixxat.com.

2.2 Hardware installation

Before connecting the CAN interface to the USB socket on your PC, you

should install the software driver first(see previous section).

2.2.1 USB-to-CANV2 compact / professional / automotive

The CAN-Interface can be connected on the fly (hot plug support).

2.2.2 USB-to-CANV2 embedded

For all work on the PC and interface, you must be statically discharged. Work

must be carried out on an earthed, anti-static work mat.

Take the following steps in sequence:

(1) Switch off the PC and unplug the power cord.

(2) Open the PC according to the instructions of the PC manufacturer

and find a suitable slot. The cable for the internal USB connection is de-

signed according to standard USB plugs (see chapter 4.3). Please note

the polarity and the occupancy of the pin connector in your PC. Do not

use force when plugging in.

(3) Make sure that the interface sits tightly in the PC.

(4) Close the PC; the hardware installation is now complete.

Connectors and displays

3 Connectors and displays

3.1 USB connector

The shield of the USB cable is connected to ground using a 100nF capacitor

and therefore also connected to ground of the USB plug.

It is recommended, that the interface is directly connected to PC USB ports or

to self powered USB hubs to ensure sufficient power supply.

USB-to-CANV2 compact / professional / automotive

The USB-cable has a plug type "A". The assignment corresponds to the

USB 2.0 standard.

USB-to-CANV2 embedded

The USB-cable has a 5-pin female connector. The assignment corre-

sponds to PC standard for internal USB devices (see chapter 4.3).

3.2 Fieldbus connector

The assignment of the fieldbus connectors (Sub-D9 and RJ45) is in accord-

ance to CiA 303-1.

The shield of the CAN connector is connected to CAN ground via a 1 MΩ re-

sistor and a 10 nF capacitor. The shields of the CAN connectors of the var-

iants USB-to-CANV2 professional and USB-to-CANV2 automotive are connect-

ed directly together.

For non galvanic decoupled CAN interfaces, fieldbus ground and PC ground

are at the same potential.

For best noise immunity, the shields of the CAN cables must directly connect-

ed to ground.

The pin assignment of the connectors CAN interfaces are shown below.
