Do the following to connect the PCAN-USB Pro adapter to the
computer and complete the initialization:
Note: Do not use a USB extension cable to connect the PCAN-
USB Pro 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 PCAN-USB Pro adapter to a USB port at the
computer. The computer can remain powered on.
Windows notifies that new hardware has been detected.
6. Windows XP only: A Wizard dialog boxes appears for the
installation of the drivers (devices “PCAN-USB-PRO-CAN
Device” and “PCAN-USB-PRO-LIN Device”). Follow its in-
structions. Deny the search for driver software at Windows
Update and select the automatic software installation during
this procedure.
All Windows operating systems: The drivers are found and

Both D-Sub connectors on the PCAN-USB Pro 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
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.
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® 102.
Figure 1: CAN pin assignment of the D-Sub connector
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).

PCAN-USB Pro – User Manual
11
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.
On the PCB of the PCAN-USB Pro adapter (casing opened) a 5-Volt
supply can optionally be routed to pin 1 of each D-Sub connector.
At delivery this pin is not assigned.
Figure 3: External 5-Volt supply at the D-Sub connectors

PCAN-USB Pro – User Manual
12
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 con-
verter is interconnected. Therefore the current output is limited to
50 mA.
Tip: On request we deliver the device configured with this
option.
Proceed as follows to activate the 5-Volt supply:
Remove the three screws at the back of the aluminum casing, take
off the cover plate and pull the PCB out of the lower part of the
casing.
Set the solder bridge(s) on the PCB of the PCAN-USB Pro adapter
according to the desired function. During this procedure take espe-
cially care not to produce unwanted short circuits on the board.
The following figure shows the positions of the solder fields on the
PCB of the PCAN-USB Pro adapter; the table below contains the
possible settings.

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 Pro while it is de-energized (the PCAN-
USB Pro 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).
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 Pro adapter does not have an internal termination.
Use the adapter on a terminated CAN bus.
Figure 5: Simple CAN connection
In this example, the PCAN-USB Pro adapter is connected with a
control unit by a cable that is terminated at both ends.

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
20 kbit/s 3.3 km
10 kbit/s 6.6 km
5 kbit/s 13.0 km
The listed values have been calculated on the basis of an idealized
system and can differ from reality.
