1 Introduction
The plug-in card PCAN-PCI Express FD enables the connection of a PC with PCI
Express slots to CAN FD and CAN networks. There is galvanic isolation of up to 500 V
between the computer and CAN sides. The card is available as a single, double, or
quad channel version.
The CAN FD standard (CAN with Flexible Data rate) is primarily characterized by
higher bandwidth for data transfer. The maximum of 64 data bytes per CAN FD frame
(instead of 8 so far) can be transmitted with bit rates up to 12 Mbit/s. CAN FD is
downward compatible to the CAN 2.0 standard, CAN FD nodes can be inserted into
already existing CAN networks without CAN FD extensions.
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 and support CAN FD.
Device drivers exist for different operating systems, so programs can easily access a
connected CAN bus.
This manual describes the use of the CAN interface with Windows.
Device drivers and application information for Linux:
www.peak-system.com/quick/DL-Driver-E
At the end of this manual you can find a Quick Reference with brief
information about the installation and operation of the CAN interface.

2 Settings
The following describes the settings for the power supply of external devices, the
internal termination, and the activation of the daisy chain. If you do not need any of
these settings, skip this chapter.
Daisy chain and power supply of external devices cannot be used
simultaneously.
2.1 Voltage Supply of External Devices
Optionally, an external power supply can be connected separately for each CAN
channel via solder bridges at pin 1 on the D-Sub connector. This allows external
devices to be supplied with a voltage of 5 V DC, such as the PCAN-TJA1054 bus
converter for Low-speed CAN. Pin 1 is not assigned at delivery. The current output is
limited to 50 mA.
2.1.1 Activate Voltage Supply
Risk of short circuit! Soldering on the CAN interface may only be
performed by qualified electrical engineering personnel.
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the card. Take precautions to avoid ESD.
Set the solder bridge(s) corresponding to the desired settings.
The following figure shows the solder field positions on the quad channel card. The
table below contains the possible settings.

2.2 Internal Termination
The termination can be activated by solder jumpers on the circuit board, to
terminate one end of the CAN bus.
Tipp: We recommend to do termination at the CAN cabling, for example
with the terminating resistors PCAN-Term (IPEK-003002) or
PCAN-MiniTerm (IPEK-003002-Mini). Thus, CAN nodes can be flexibly
connected to the bus.
2.2.1 Activate Internal Termination
Risk of short circuit! Soldering on the CAN interface may only be
performed by qualified electrical engineering personnel.
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.
Following figure on the next page shows the positions of the solder fields of the quad
channel card. The solder fields for the single and double channel card are located in
the same positions and can therefore also be taken from the figure. The table below
contains the possible settings.

2.3 Daisy Chain
Only quad channel card: The daisy chain can be activated via solder jumpers on the
board to connect a CAN-FD-optimized connection to an existing CAN bus. This makes
interference-free operation possible at higher CAN FD bit rates, because stubs and Y
distributions are avoided as far as possible.
2.3.1 Connection example and assignment
For cabling, the cables and connectors must be assembled accordingly.
The optional voltage supply for external devices can not be operated
simultaneously with the daisy chain.
When daisy chain is activated, the pin assignment is as follows:

9. Turn on the computer and start Windows.
Windows detects the new hardware and completes the driver installation.
3.3 Check Operational Readiness
1. Open the Windows Start menu.
2. Type Peak Settings and press |Enter|.
The window PEAK Settings appears.
3. Select CAN Hardware.
The connected CAN interface is displayed.
3.3.1 Plug-in card is not listed
The PCAN-PCI Express FD card uses the PCIe standard 1.0. It may happen that the
card is not detected by the system. This may occur, when the PCIe standard on your
system is newer than "1.0" or when the card is in a PEG slot.
You can ensure correct recognition of the card by changing the settings in the
computer BIOS.
Make the following settings in the BIOS of your computer mainboard:
1. For the PCIe slot in use, set 1.0 for PCIe support.
Possible terms for the setting: Gen1, Legacy, 1.0
2. To use the card in a PEG slot, enable the “Early PCIe Delay” option.
The terms and availability of the above options may differ depending on
the mainboard used. Therefore, check the user manual of the
mainboard or contact the manufacturer.

4.2 Cabling
4.2.1 Termination
The High-speed CAN bus (ISO 11898-2) must be terminated with 120 Ω on both ends.
The termination prevents interfering signal reflections and ensures the proper
operation of the transceivers of the connected CAN nodes (CAN interfaces,
controldevices).
The CAN interface PCAN-PCI Express FD does not have an internal termination. Use
the CAN interface on a terminated CAN bus.
4.2.2 Example of a Connection
This example shows a connection between the PCAN Interface and a control unit
(ECU). The upper example shows a connection with a cable which is terminated with
120 Ω at both ends. At the lower example the connection is made with termination
adapters.

4.2.3 Maximum Bus Length
The maximum bus length depends primarily on the bit rate:
Nominal bit rate Buslength
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
25 kbit/s 2.5 km
The listed values have been calculated on the basis of an idealized system and can
differ from reality.
Note: For CAN FD, the same maximum bus lengths applys as for CAN,
despite the higher data bit rate of CAN FD. The dependency is based on
the bit rate during the arbitration, called nominal bit rate.
4.3 Example Application under Windows
As an example application for accessing the CAN interface, run the CAN monitor
PCAN-View from the Windows Start menu.
