1Introduction
The PCAN-PCI Express card enables the connection of a PC with
PCI Express slots to CAN networks. The card is available as a single,
dual, or four-channel version. Device drivers and programming
interfaces exist for different operating systems, so programs can
easily access a connected CAN bus.
Tip: At the end of this manual (Appendix C) you can find a
Quick Reference with brief information about the installation
and operation of the PCAN-PCI Express card.

2Installing the Software and
the Card
This chapter covers the software setup for the PCAN-PCI Express
card (short: PCIe card) under Windows and the installation of the
card in the computer.
Setup the driver before installing the PCIe card.
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 PCIe card 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-PCI.
4. Click on Install now. The setup program for the driver is
executed.
5. Follow the instructions of the setup 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.

Do the following to install the PCIe card into the computer:
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the PCAN-PCI Express card. Take precautions
to avoid ESD when handling the card.
1. Four-channel version only: Connect the 10-pin connector of
CAN ports 3 and 4 with a cable from the slot bracket.
Figure 1: Position of the sockets for the CAN connection,
CAN 3 (upper left position), CAN 4 (upper right position)
2. Shut down the computer and switch it off.
3. Disconnect the computer from the power supply.
4. Open the computer's casing.
5. If applicable, remove a front blind in front of the desired slot
of the PCIe card. The additional slot bracket with connectors
used by the four-channel version needs a further place.
6. Insert the PCIe card into a vacant PCI Express slot. For
details refer to the documentation of the computer.
7. Close the computer's casing.
8. Reconnect the power supply of the computer.

Do the following to complete the initialization:
1. Turn on the computer and start Windows. Make sure again
that you are logged in as user with administrator privileges.
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 the 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 you can find
the entry “PCAN-PCI Express” in the branch “CAN-Hardware” of the
Windows Device Manager.

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 2: Pin assignment of High-speed CAN connection
(view onto a male connector on the PCAN-PCI Express card)
With pin 1 devices with low power consumption (e.g. bus conver-
ters) can be directly supplied via the CAN connector. At delivery this
pin is not assigned. You can find a detailed description in the follo-
wing 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).
