1Introduction
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 make 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 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.
Device drivers and programming interfaces exist for different opera-
ting 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.

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 1: Pin assignment High-speed CAN
(view onto connector of the PCAN-USB FD adapter)
With the pin 1 devices with low power consumption (e.g. bus
converters) can be directly supplied via the CAN connector. At
delivery these pin are not assigned. You can find a detailed
description about the activation in the following 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).

3.2 Supplying External Devices via the CAN
Connector
On the PCAN-USB FD board (casing opened) a 5-Volt supply can
optionally be routed to pin 1 of the D-Sub connector. Thus devices
with low power consumption (e.g. external bus converters) can be
directly supplied via the CAN connector.
When using this option the 5-Volt supply is connected to the power
supply of the computer and is not fused separately. A DC/DC
converter is interconnected. Therefore the current output is limited
to 50 mA
Proceed as follows to activate the 5-Volt supply:
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the PCAN-USB FD board. Take precautions to
avoid ESD when handling the card.
1. In order to access the board, open the casing of the PCAN-
USB FD adapter by cautiously pushing in the latches on
both sides, e.g. with a flat tip screwdriver.
2. Remove the board.
3. Set the solder bridge on the board of the PCAN-USB FD
adapter according to the following figure.
During this procedure take especially care not to produce unwanted
short circuits on the board.
Figure 2 shows the position of the solder field JP4 on board of the
PCAN-USB FD.

Figure 2: Top view PCAN-USB FD board, solder field JP4
For reassembly place the board overhead onto the top part of the
casing. Ensure that the cable is lying with the strain relief in the cut-
out of the casing, and that the LED is placed in the corresponding
hole. Push the bottom part of the casing onto the top part (the
latches click in).
Attention! Risk of short circuit! If the option described in this
section is activated, you may only connect or disconnect CAN
cables or peripheral systems (e.g. external bus converters) to or
from the PCAN-USB FD adapter while it is de-energized (the
adapter is not connected to the computer). Consider that some
computers still supply the USB ports with power even when
they are turned off (standby operation).

3.3 CAN Termination
The termination can be activated by solder jumpers on the board. 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. If a CAN bus is not terminated
correctly, activate the internal termination.
To activate the termination, the solder fields JP1 and JP2 must
be soldered. Proceed as follows to activate the termination:
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the PCAN-USB FD board. Take precautions to
avoid ESD when handling the card.
1. Open the casing of the PCAN-USB FD adapter by cautiously
pushing in the latches on both sides, e.g. with a flat tip
screwdriver.
2. Remove the board.
3. Set the both solder bridges on the board of the PCAN-USB
FD adapter to activate the termination.
During this procedure take especially care not to produce unwanted
short circuits on the board.
Figure 3 shows the positions of the solder fields JP1 and JP2 on
board of the PCAN-USB FD.

3.4 Cabling
3.4.1 Termination
A High-speed CAN bus (ISO 11898-2) must be terminated on both
ends with 120 Ohms. Otherwise, there are interfering signal
reflections and the transceivers of the connected CAN nodes (CAN
interface, control device) will not work.
The PCAN-USB FD adapter has a switchable internal termination
(see section 3.3 on page 13). If a CAN bus is not terminated cor-
rectly, activate the internal termination.
3.4.2 Example of a Connection
Figure 4: Simple CAN connection
In this example, the PCAN-USB FD adapter is connected with a
control unit by a cable that is terminated at 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:

PCAN-USB FD – User Manual
16
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
The listed values have been calculated on the basis of an idealized
system and can differ from reality.
The dependency of the bus length of the transmission rate is based
on the arbitration phase of CAN communication. For CAN FD the
transmission rate of arbitration is determined by the nominal bit
rate. Through this can only take a maximum value of 1 Mbit/s, apply
for CAN FD the same maximum bus lengths as for CAN, despite the
higher data transfer.

Note: Both transmission rates must match those which are
used by all nodes on the CAN bus. You can create user-defined
transmission rates using the button to the right of the drop-
down lists.
5. 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).
6. 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).
7. Finally, confirm the settings in the dialog box with OK. The
main window of PCAN-View appears (see Figure 7).
