1 Introduction
The PCAN-USB Pro FD adapter enables the connection of CAN FD
and LIN networks to a computer via USB. Two field busses can be
connected at the same time, up to four with appropriate adapter
cables (2 x CAN FD, 2 x LIN). Each CAN FD channel is separately
isolated against USB and LIN with a maximum of 500 Volts. Its
robust aluminum casing makes the PCAN-USB Pro FD adapter
suitable for mobile applications.
The new CAN FD standard (CAN with Flexible Data Rate) is prima-
rily characterized by higher bandwidth for data transfer. The maxi-
mum 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 new
standard CAN FD.
The monitor application PLIN-View Pro as well as the PLIN
programming interface are included in the scope of supply.
Device drivers exist for different operating systems, so programs
can easily access a connected CAN and/or LIN 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 Pro FD adapter.

2 Installing the Software and
the Adapter
This chapter covers the software setup for the PCAN-USB Pro FD
adapter under Windows and the connection of the adapter to a
computer.
Install the driver before you connect the adapter to the computer.
Do the following to install the drivers:
1. Start Intro.exe from the supplied 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 to
"Installer database of PEAK Drivers".
The driver setup starts.
4. Follow the instructions of the program. When getting to the
components selection, add the LIN Driver.
Do the following to connect the adapter:
Note: Do not use a USB extension cable to connect the PCAN-
USB Pro FD adapter to the computer. The use of an extension
cable does not comply with the USB specification and can lead
to malfunction of the adapter.
1. Connect the adapter to a USB port at the computer. The
computer can remain powered on.
Windows detects the new hardware and completes the
driver installation.
2. Check the LEDs on the adapter. If the LEDs are green, then
the driver was initialized successfully.

3 Connecting the CAN and LIN
Bus
Both D-Sub connectors on the PCAN-USB Pro FD adapter are each
used for connecting one CAN and one LIN bus. The pin assignment
is identical for both D-Sub connectors.
Note: Since the application possibilities of the PCAN-USB Pro
FD adapter are various, special cable adapters for connecting
the CAN and LIN busses are not provided. Therefore you need
a 9-pin D-Sub female connector for your appliances to be
connected individually.
3.1 CAN Connection over D-Sub Connector
Two High-speed CAN busses (ISO 11898-2) can be connected, one
to each D-Sub connector. The pin assignment for CAN corresponds
to the specification CiA® 303-1.
Figure 1: CAN pin assignment of the D-Sub connector
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 3.3.

PCAN-USB Pro FD – User Manual
11
Each CAN connection separately has a galvanic isolation up to
500 V against USB and LIN.
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 LIN Connection over D-Sub Connector
Two LIN busses can be connected, one to each D-Sub connector.
Figure 2: LIN pin assignment of the D-Sub connector
For the LIN operation an additional supply voltage must be applied
to pin Vbat-LIN (8 - 18 V DC, e.g. car battery). Both LIN connections
need their own supply.
Both LIN connections have a common galvanic isolation up to 500 V
against USB and CAN. The LIN connections are not galvanically
isolated against each other.

3.3 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
per CAN channel on the PCAN-USB Pro 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.
Figure 3: External 5-Volt supply at the D-Sub connectors
Tip: On request we deliver the device configured with this
option.
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.
1. Remove the three screws at the back of the casing.

2. Remove the two outer screws next to the D-Sub connectors
at the front of the casing.
Figure 5: Attachment points of the D-Sub connectors
at the front side of the casing
3. Remove the casing cover.
4. Lift the back of the case and slide the circuit board in
direction of the front over the lower part of the casing. The
bottom of the circuit board is accessible now.
5. Set the solder bridges on the circuit board of the adapter to
activate the termination.
Figure 6 shows the positions of the solder fields for the
termination.
6. Reassemble the device. Slide the circuit board back into the
lower part of the casing.
7. Close the casing cover.
8. Screw the front and back side (Figure 4 and Figure 5).

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.
Consider that some computers still supply the USB ports with
power even when they are turned off (standby operation).

3.4 Activating the Internal CAN
Termination
The termination can be activated by solder jumpers for each
channel 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.
Do the following to activate the internal termination:
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.
1. Remove the three screws at the back of the casing.

3.5 Cabling
3.5.1 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-USB Pro FD adapter has an internal termination. For
more information, see chapter 3.4.
3.5.2 Example of a Connection
Figure 10: Simple CAN connection
In this example, the PCAN-USB Pro FD adapter is connected with a
control unit by a cable that is terminated with 120 ohms at both
ends.

PCAN-USB Pro FD – User Manual

3.5.3 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
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 apply 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. The nominal bite rate at CAN FD can be
up to 1 Mbit/s.
