1 Introduction
The PCAN-PCI Express card enables the connection of a PC with
PCI Express slots to CAN networks. There is galvanic isolation of up
to 500 Volts between the computer and CAN sides. The card is
available as a single, dual, or four-channel version.
The monitor software PCAN-View and the programming interface
PCAN-Basic for the development of applications with CAN
connection are included in the scope of supply.
Device drivers 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.

2 Installing the Software and
the Card
This chapter covers the software setup for the PCAN-PCI Express
card in Windows and the installation of the card in the computer.
Install the driver before you install the card.
Do the following to install the driver:
1. Start Intro.exe from the root directory of the DVD.
The navigation program starts.
2. Select in the main menu Drivers and click on Install now.
3. Confirm the message of the User Account Control related
"Installer database of PEAK Drivers".
The driver setup starts.
4. Follow the program instructions.
Do the following to install the card:
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the card. Take precautions to avoid ESD.
1. Four-channel version only: Connect the 10-pin connector of
CAN ports 3 and 4 with a cable from the slot bracket.
2. Shut down the computer.
3. Disconnect the computer’s power supply.
4. Open the computer case.
5. Insert the PCI Express card into an available PCI Express
slot.

6. Four-channel version only: The additional slot bracket with
connectors used by the four-channel version needs a further
place.
7. Insert the PCI Express card into an available PCI Express
slot.
8. Close the computer case.
9. Reconnect the computer power supply.
10. Turn on the computer and start Windows.
Windows detects the new hardware and completes the driver
installation.
Do the following to check the operational readiness:
1. Open the Windows Start menu.
2. Type peakcpl and press Enter .
The information window for PEAK hardware appears. The plug-in
card must be displayed in the table on the CAN Hardware tab.

3 Connecting the CAN Bus
3.1 Connection over 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® 303-1.
Figure 1: Position of the sockets for the CAN connection,
CAN 3 (upper left position), CAN 4 (upper right position)
Figure 2: Pin assignment of High-speed CAN connection
(view onto a male connector on the PCAN-PCI Express card)

PCAN-PCI Express – User Manual
11
Low power devices (e.g. bus converters) can be supplied directly
with 5 volts over pin 1 of the CAN connector. Pin 1 is not in use at
the delivery state. For more information see the next section 3.2.
Tip: Connect a CAN bus with a different transmission standard
via a bus converter. PEAK-System offers different bus converter
modules like the PCAN-TJA1054 for a Low-speed CAN bus
according to ISO 11898-3.
The pin assignment between the D-Sub port and the 10-pin connec-
tor on the PCAN-PCI Express Four Channel card for channel 3 and 4
is as follows:

3.1.1 Slot Bracket with D-Sub Connectors
Figure 4: Dual channel slot bracket
Four-channel version only: To connect a CAN bus to the PCAN-PCI
Express card, use the supplied slot bracket. After you have con-
nected the cables from the slot bracket with the 10-pin sockets of
CAN port 3 and 4, you can connect the CAN busses with the
D-Sub sockets.

3.2 Voltage Supply of External Devices
External devices with low power consumption (e.g. bus converters)
can be directly supplied via the CAN connector (independently for
each connector on the dual or four-channel version). With a solder
bridge per CAN channel on the PCAN-PCI Express board, a 5-Volt
supply can optionally be routed to pin 1 of the D-Sub connector.
The current output is limited to 50 mA.
Do the following to activate the voltage supply:
Risk of short circuit! Solder with great care to avoid unwanted
short circuits on the card.
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the card. Take precautions to avoid ESD.
Set the solder bridges corresponding to the desired settings.
Figure 5 shows the solder field positions on the card. The table
below contains the possible settings.

Risk of short circuit! The 5-Volt supply is not protected
separately. Therefore, turn off the computer before you
connect and disconnect CAN cables or peripheral systems.

3.3 Cabling
3.3.1 Termination
The High-speed CAN bus (ISO 11898-2) must be terminated with
120 ohms at both ends. The termination prevents interfering signal
reflections and ensures the proper operation of the transceiver of
the connected CAN nodes (CAN interface, control device).
The PCAN-PCI Express card does not have an internal termination.
Use the card on a terminated CAN bus.
3.3.2 Example of a Connection
Figure 6: Simple CAN connection
In this example, the PCAN-PCI Express card is connected with a
control unit by a cable that is terminated with 120 ohms at both
ends.

3.3.3 Maximum Bus Length
High-speed CAN networks may have bit rates of up to 1 Mbit/s. The
maximum bus length depends primarily on the bit rate.
The following table shows the maximum possible CAN bus length
at different bit rates:
Bit rate Bus length
1 Mbit/s 40 m
500 kbit/s 110 m
250 kbit/s 240 m
125 kbit/s 500 m
50 kbit/s 1.3 km
20 kbit/s 3.3 km
10 kbit/s 6.6 km
5 kbit/s 13.0 km
The listed values have been calculated on the basis of an idealized
system and can differ from reality.

4 Software and API
This chapter covers the provided software PCAN-View and the
programming interface PCAN-Basic.
4.1 Monitor Software PCAN-View
PCAN-View is simple Windows software for viewing, transmitting,
and logging CAN and CAN FD messages.
Note: This chapter describes the use of PCAN-View with a CAN
adapter.

Do the following to start and initialize PCAN-View:
1. Open the Windows Start menu and select PCAN-View.
The Connect dialog box appears.
Figure 8: Selection of the hardware and parameters
2. Select an interface from the list.
3. From the drop-down list, select the Bit rate that is used by
all nodes on the CAN bus.
Tip: You can create custom bit rates by using the button ().
4. Under Filter settings you can limit the range of CAN IDs to
be received, either for standard frames (11-bit IDs) or for
extended frames (29-bit IDs).
5. Activate the Listen-only mode if you do not actively
participate in the CAN traffic and just want to observe. This
also avoids an unintended disruption of an unknown CAN
environment (e.g. due to different bit rates).
6. Confirm the settings in the dialog box with OK. The main
window of PCAN-View appears (see Figure 9).

4.1.1 Receive/Transmit Tab
Figure 9: Receive/Transmit Tab
The Receive/Transmit tab is the main element of PCAN-View. It
contains two lists, one for received messages and one for the
transmit messages. The CAN data format is hexadecimal by default.
Do the following to transmit a CAN message with PCAN-View:
1. Select the menu command Transmit > New Message
(alternatively or Ins ).
The New Transmit Message dialog box appears.
Figure 10: Dialog box new transmit message

2. Enter the ID, the data Length, and the CAN message Data.
Note: With the program version 4 of PCAN-View, the DLC field
was renamed to Length. Latter reflects the actual data length.
3. Enter a value into the Cycle Time field to choose manually
or periodically message transmission. Enter a value greater
than 0 to transmit periodically. Enter the value 0 to transmit
only manually.
4. Confirm the entries with OK.
The created transmit message appears on the
Receive/Transmit tab.
5. Trigger selected transmit messages manually with the menu
command Transmit > Send (alternatively Space bar). The
manual transmission for CAN messages being transmitted
periodically is carried out additionally.
Tip: Under the menu command File > Save, you can save the
current transmit messages into a transmit list. Saved transmit
lists are available for reuse.
