1 Introduction
The CANFDAdapter PCAN-USBFD allows the connection of CANFD and CAN
networks to a computer via USB. A galvanic isolation of up to 500 Volts decouples the
PC from the CANbus. The simple handling and its compact plastic casing makes the
adapter suitable for mobile applications.
The new 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 down-
ward-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 applic-
able.
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 new standard CANFD.
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-USBFD adapter.

3 Connecting the CANBus
3.1 Connection over D-Sub Connector
A High-speed CAN bus (ISO11898-2) connected to the 9-pin D-Sub connector. The pin
assignment for CAN corresponds to the specification CiA®303-1.
Figure 1: Pin assignment High-speed CAN (view onto connector of the PCAN-USBFD adapter)
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 infor-
mation see 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.
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. With a solder bridge for the one CANchannel on the

PCAN-USBFDboard (casing opened), 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:
Attention! Risk of short circuit! Solder with great care to avoid
unwanted short circuits on the circuit board.
Attention!Electrostatic discharge (ESD) can damage or
destroy components on the circuit board. Take precautions to
avoid ESD.
1. Open the adapter casing. Push the latches on both sides cautiously, e.g. with a
flat tip screwdriver.
2. Remove the board.
3. Set the solder bridge.

4. Close the case. Place the board overhead onto the top part of the casing.
Note: The cable must lie with the strain relief in the
cut-out of the casing and the LED must be in the corres-
ponding hole.
5. Push the bottom part of the casing onto the top part until the latches click in.
Attention! 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 peri-
pheral systems. Consider that some computers still
supply the USB ports with power even when they are
turned off (standby operation).
3.3 Activating Internal Termination
The internal termination can be activated with solder jumpers on the board to
terminate one end of the CAN bus with 120Ohms. At delivery the termination is not
activated. A High-speed CANbus (ISO11898-2) must be terminated on both ends
with 120Ohms. Otherwise disturbances may arise.
Do the following to activate the internal termination:
Attention! Risk of short circuit! Solder with great care to avoid
unwanted short circuits on the circuit board.

3.4 Cabling
3.4.1 Termination
The High-speed CANbus (ISO11898-2) must be terminated with 120Ohms 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Ohms. For more
information see chapter 3.3 .
3.4.2 Example of a Connection
Figure 4: Simple CAN connection
This example shows a connection between the PCAN-USBFD adapter and a control
unit. The connection cable is terminated with 120Ohms on both ends.
3.4.3 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:
3 Connecting the CANBus PCAN-USBFD
User Manual 1.5.0 © 2021 PEAK-System Technik GmbH
13

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
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 depen-
dency is based on the bit rate during the arbitration, called
nominal bit rate. The nominal bite rate at CANFD can be up to
1Mbit/s.

are used by all nodes on the CANbus.
Tip: You can create custom bit rates by using the
button (▶).
7. 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)
8. 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).
