1.2 Important Notes

1.2.1 Safety Instructions and Hazard Warnings

Caution!In order to avoid personal injuries and damage to property, you have to read andunderstand the following safety instructions and hazard warnings prior to installationand use of this interface. Keep this documentation (manual) always near the inter-face.

1.2.1.1 Proper Use and Intended Purpose

Caution!The interface is designed for analyzing, controlling and otherwise influencing controlsystems and electronic control units. This includes, inter alia, bus systems likeCAN, LIN, K-Line, MOST, FlexRay, Ethernet, BroadR-Reach and/or ARINC 429.

The interfacemay only be operated in a closed state. In particular, printed circuitsmust not be visible. The interfacemay only be operated (i) according to the instruc-tions and descriptions of this manual; (ii) with the electric power supply designed forthe interface, e.g. USB-powered power supply; and (iii) with accessories man-ufactured or approved by Vector.

The interface is exclusively designed for use by skilled personnel as its operationmay result in serious personal injuries and damage to property. Therefore, onlythose persons may operate the interface who (i) have understood the possibleeffects of the actions whichmay be caused by the interface; (ii) are specificallytrained in the handling with the interface, bus systems and the system intended tobe influenced; and (iii) have sufficient experience in using the interface safely.

The knowledge necessary for the operation of the interface can be acquired in work-shops and internal or external seminars offered by Vector. Additional and interfacespecific information, such as „Known Issues“, are available in the „Vector Know-ledgeBase“ on Vector´s website at www.vector.com. Please consult the „VectorKnowledgeBase“ for updated information prior to the operation of the interface.

1 Introduction


1.2.1.2 Hazards

Caution!The interfacemay control and/or otherwise influence the behavior of control sys-tems and electronic control units. Serious hazards for life, body and property mayarise, in particular, without limitation, by interventions in safety relevant systems(e.g. by deactivating or otherwisemanipulating the enginemanagement, steering,airbag and/or braking system) and/or if the interface is operated in public areas (e.g.public traffic, airspace). Therefore, youmust always ensure that the interface isused in a safemanner. This includes, inter alia, the ability to put the system inwhich the interface is used into a safe state at any time (e.g. by „emergency shut-down“), in particular, without limitation, in the event of errors or hazards.

Comply with all safety standards and public regulations which are relevant for theoperation of the system. Before you operate the system in public areas, it should betested on a site which is not accessible to the public and specifically prepared forperforming test drives in order to reduce hazards.

1.2.1.3 Disclaimer

Caution!Claims based on defects and liability claims against Vector are excluded to theextent damages or errors are caused by improper use of the interface or use notaccording to its intended purpose. The same applies to damages or errors arisingfrom insufficient training or lack of experience of personnel using the interface.

Extendedmeasuringrange of theanalog input

In normal operation, voltages up to 18 V can be applied andmeasured at the ana-log input. The cutoff frequency fc (-3 dB) for AC voltages is approx. 7.2 kHz.

For measurements above 18 V (max. 50 V), an external series resistor has to beapplied to the analog input. The series resistor Rext depends on themaximuminput voltage Uinput to bemeasured and can be calculated as follows:

The cutoff frequency for AC voltages is also affected by the external series res-istor:

3.1 Driver InstallationGeneralinformation

The Vector Driver Disk offers a driver setup which allows the installation or theremoval of Vector devices.

NotePlease note that you will needAdministrator Rights for the following steps.

Step by Step Procedure

1. Execute the driver setup from the autostart menu or directly from\Drivers\Setup.exe before the device is connected to the PC with theincluded USB cable.

If you have already connected the device to the PC, theWindows found newHardwarewizard appears. Close this wizard and then execute the driver setup.

2. Click [Next] in the driver setup dialog. The initialization process starts.

3 Getting Started


3. In the driver selection dialog, select your devices to be installed (or to be unin-stalled).

4. Click [Install] to execute the driver installation, or [Uninstall] to remove exist-ing drivers.

5. A confirmation dialog appears. Click [Close] to exit. After successful instal-lation, the device is ready for operation and can be connected to the PC withthe included USB cable and powered by supplying external voltage (e. g. withan appropriate cable offered by Vector).

6. Install or update your CANoe to version 10.0 SP2 or higher.

3 Getting Started


3.2 Device ConfigurationConfiguration Before the installed device can be used in an application, it must be properly con-

figured for the needed use case. This configuration is done with theVector HardwareConfig tool which comes with the driver installation. The tool can be found inWin-dows | Start | Settings | Control Panel | Vector Hardware andmanages allinstalled Vector devices.

ReferenceFurther details onVector Hardware Config can be found in the installation instruc-tions (see section Vector Hardware Configuration on page 25).

5.1 General InformationTime stampsand events

Time stamps are useful when analyzing incoming or outgoing data or eventsequences on a specific bus.

Figure 20: Time stampsof two CAN channels in CANalyzer

Generatingtime stamps

Each event which is sent or received by a Vector network interface has an accuratetime stamp. Time stamps are generated for each channel in the Vector network inter-face. The base for these time stamps is a common hardware clock in the device.

Figure 21: Common time stamp clock for each channel

If themeasurement setup requires more than one Vector network interface, a syn-chronization of all connected interfaces and their hardware clocks is needed.

Due tomanufacturing and temperature tolerances, the hardware clocks may vary inspeed, so time stamps of various Vector devices drift over time.

To compensate for these time stamp deviations between the Vector network inter-faces, the time stamps can be either synchronized by software or by hardware (seenext section).

NoteThe accuracy of the software and hardware sync depends on the interface. Furtherinformation on specific values can be found in the technical data of the respectivedevices.



5.2 Software SyncSynchronizationby software

The software time synchronization is driver-based and available for all applicationswithout any restrictions. The time stamp deviations from different Vector network inter-faces are calculated and synchronized to the common PC clock. For this purpose nofurther hardware setup is required.

5.3 Hardware SyncSynchronizationby hardware

A more accurate time synchronization of multiple devices is provided by the hardwaresynchronization which has to be supported by the application (e. g. CANalyzer,CANoe). Two Vector network interfaces can therefore be connected with theSYNCcableXL (see accessories manual, part number 05018).

In order to synchronize up to five devices at the same time, a distribution box is avail-able (see accessories manual, part number 05085).
