2Installing the Software and

the Adapter

This chapter covers the software setup for the PCAN-USB adapter

under Windows and the connection of the adapter to the computer.

Setup the driver before connecting the PCAN-USB adapter to the

computer for the first time.

Do the following to install the driver:

1. Make sure that you are logged in as user with administrator

privileges (not needed for normal use of the PCAN-USB

adapter later on).

2. Insert the supplied DVD into the appropriate drive of the

computer. Usually a navigation program appears a few

moments later. If not, start the file Intro.exe from the root

directory of the DVD.

3. On the page English > Drivers activate the entry PCAN-USB.

4. Click on Install now. The setup program for the driver is

executed.

5. Follow the instructions of the program.

Tip: If you don't want to install the CAN monitor PCAN-View for

Windows onto the hard disk together with the driver, you have

the option to start the program later directly from DVD without

prior installation.

PCAN-USB – User Manual

Do the following to connect the PCAN-USB adapter to the

computer and complete the initialization:

Note: Do not use a USB extension cable to connect the PCAN-

USB adapter to the computer. The use of an extension cable

does not comply with the USB specification and can lead to

malfunction of the adapter.

1. Connect the PCAN-USB adapter to a USB port of the

computer or of a connected USB hub. The computer can

remain powered on.

Windows notifies that new hardware has been detected.

2. Windows XP only: A Wizard dialog box appears. Follow its

instructions. Deny the search for driver software at

Windows Update and select the automatic software

installation during this procedure.

All Windows operating systems: The drivers are found and

installed by Windows.

3. Afterwards you can work as user with restricted rights

again.

After the initialization process is finished successfully the red LED

on the PCAN-USB adapter is illuminated.

3Connecting the CAN Bus

3.1 D-Sub Connector

A High-speed CAN bus (ISO 11898-2) is connected to the 9-pin

DSub connector. The pin assignment for CAN corresponds to the

specification CiA® 102.

Figure 1: Pin assignment High-speed CAN

(view onto connector of the PCAN-USB adapter)

With the pins 1 and 9 devices with low power consumption (e.g. bus

converters) can be directly supplied via the CAN connector. At deli-

very these pins are not assigned. You can find a detailed description

about the activation in the following section 3.2.

Tip: You can connect a CAN bus with a different transmission

standard via a bus converter. PEAK-System offers different bus

converter modules (e.g. PCAN-TJA1054 for a Low-speed CAN

bus according to ISO 11898-3).
