1 Introduction
The PCAN-USB FD interface enables simple connection to CAN FD and CAN
networks. Its compact plastic casing makes it suitable for mobile applications. A
galvanic isolation of up to 500 Volts decouples the PC from the CAN bus.
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 A/B standard, thus CAN FD nodes can be
used in existing CAN networks. However, in this case the CAN FD extensions are not
applicable.
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 the standard 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 PCAN-USB FD
interface.

2 Settings
The following describes the settings for the power supply of external devices and
the internal termination. If you do not need any of these settings, skip this chapter.

2.1 Voltage Supply of External Devices

Optionally, an external power supply can be connected via the D-Sub connector
using solder bridges at pin 1 and/or pin 9 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 Power 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.

2.2 Internal Termination
The internal termination can be activated by solder jumpers on the circuit board to
terminate one end of the CAN bus. At delivery the termination is not activated.

Tip: 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

4 Connecting the CAN Bus
4.1 Connection over D-Sub Connector
After the CAN interface is connected, a CAN bus can be connected to the
D-Sub connector. The pin assignment for CAN corresponds to the specification
CiA® 106:

Pin Assignment D-Sub plug

1 CAN_V+ (optional)
2 CAN_Low
3 CAN_GND
4 Not connected
5 Not connected
6 CAN_GND
7 CAN_High
8 Not connected
9 Not connected

Low power devices can be supplied directly with 5 Volts over pin 1 of the CAN
connector, for example bus converters. Pin 1 is not in use at the delivery state. For
more information see section 2.1 Voltage Supply of External Devices.

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.

User Manual 2.2.0 © 2024 PEAK-System Technik GmbH
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 PCAN-USB FD has an optional internal termination with 120 Ω. For more
information see chapter 2.2 Internal Termination.

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 Connecting the CAN Bus PCAN-USB FD 15

User Manual 2.2.0 © 2024 PEAK-System Technik GmbH
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.

7 API PCAN-Basic

The intended use of PCAN-Basic requires compliance with the license

rights. Read the license agreement for end users at:
https://www.peak-system.com/quick/eula

The programming interface (API) PCAN-Basic provides basic functions for the
connection of own programs to the CAN and CAN FD Interfaces of PEAK-System.
PCAN-Basic is the interface between the program and the device driver. In Windows
operating systems this is a DLL (Dynamic Link Library) and in Linux operating
systems an SO (Dynamic Shared Object). PCAN-Basic is designed to be cross-
operating system compatible. Software projects can be ported between supported
systems with little effort.
With the installation of the device driver package under Windows the DLL files of
the API PCAN-Basic are placed in the system folder. Examples for all common
programming languages as well as libraries and help files are available as a
download package at: www.peak-system.com/quick/DL-Develop-E

7 API PCAN-Basic PCAN-USB FD 27

User Manual 2.2.0 © 2024 PEAK-System Technik GmbH
For Linux, a download of the API is available under this link. For a use of PCAN-
Basic another driver package with a chardev driver is needed, because an access
under SocketCAN is not possible. The "Driver Package for Proprietary Purposes",
the user manual, and further information about the implementation can be found
at www.peak-system.com/linux.

7 API PCAN-Basic PCAN-USB FD 28

User Manual 2.2.0 © 2024 PEAK-System Technik GmbH
7.2 Principle Description of the API
The sequence of accessing the CAN interface is divided into three phases:

Initialization
A CAN channel must be initialized before using it. This is done by the simple call of
the function CAN_Initialize for CAN and CAN_InitializeFD for CAN FD.
Depending on the type of the CAN hardware, up to 16 CAN channels can be opened
at the same time. After a successful initialization the CAN channel is ready. No
further configuration steps are required.

Interaction
For receiving and transmitting messages the functions CAN_Read and CAN_
Write as well as CAN_ReadFD and CAN_WriteFD are available depending on
the initialization mode. Additional settings can be made, such as setting up
message filters to confine to specific CAN IDs or setting the CAN controller to
Listen-only mode.
When receiving CAN messages, events are used for an automatic notification of an
application (client). This offers the following advantages:
■ The application no longer needs to check for received messages periodically
(no polling).
■ The response time at reception is reduced.

Completion
To end the communication the function CAN_Uninitialize is called in order to
release the reserved resources for the CAN channel, among others. In addition the
CAN channel is marked as "Free" and is available to other applications.

Appendix E Linux
Depending on the Kernel version, device drivers for the CAN interfaces from PEAK-
System are already included in the operating system. The PCAN interfaces are
handled as network devices (SocketCAN, netdev). You can find the documentation
for SocketCAN under:
https://www.kernel.org/doc/Documentation/networking/can.txt
The following command lists the available drivers:

grep PEAK_ /boot/config-`uname -r`

Whether the required driver for the PCAN interface is present and loaded can be
checked with the following command:

lsmod | grep ^peak check

If the initialization was successful, the response line starts with peak_usb.
You can find a recent list of which PCAN interface is supported from which kernel
version onwards on our Linux website.

Attention: Since the end of 2022 there is PCAN-USB FD with a

different hardware version, which is only supported with kernel 6.x
and higher or with the peak-linux-driver-8.15.

If the required drivers are not listed, install the "Driver Package for Proprietary
Purposes". The download and documentation for the driver can also be found on:
www.peak-system.com/linux
This driver package is also needed to use the APIs based on the chardev driver, for
example PCAN-Basic, libpcan, or libpcanfd.
