1Introduction
Tip: At the end of this manual (Appendix B) you can find a
Quick Reference with brief information about the installation
and operation of the PCAN-Dongle.
The PCAN-Dongle allows the connection of a CAN bus to the
parallel port of a computer. Therefore the computer can easily be
integrated into a High-speed CAN network.
The opto-decoupled model of the PCAN-Dongle additionally
contains a galvanic isolation. An isolation of up to 500 V between
the computer and the CAN parts of the interface is achieved by use
of a DC/DC converter and an optocoupler.
Note: This manual refers to both the PCAN-Dongle standard
model as well as the one with galvanic isolation. Differences at
use and at the technical specifications are mentioned
accordingly in this manual.

CAN connection 9-pin D-Sub male, pin assignment according to
CiA recommendation DS 102
Galvanic isolation up to 500 V for the CAN interface (only opto-
decoupled model)
Power supply (5 V) via cable with T-piece for keyboard
connector (DIN or PS/2)
Support for operating systems Windows (starting with 2000) and
Linux
Note: This manual describes the use of the PCAN-Dongle with
Windows. You can find device drivers for Linux and the
corresponding information on PEAK-System's website under
www.peak-system.com/linux.
1.2 System Requirements
The following prerequisites must be given, so that the PCAN-Dongle
can be used properly:
A free parallel port (D-Sub, 25 pins) at the computer, capable of
interrupts
Operating system Windows (Vista, XP SP2, 2000 SP4) or Linux
1.3 Scope of Supply
The scope of supply normally consists of the following parts:
PCAN-Dongle (case with two ports and a cable with T-piece for
DIN or PS/2 keyboard connector)
CD-ROM with software (drivers, utilities), programming
examples, and documentation

2Hardware Installation
2.1 Connecting to the Computer
1. Make sure that the computer is turned off.
2. Connect the PCAN-Dongle with the wider port (25 pins) to
the free parallel port at the computer.
3. Pull the keyboard connector from the corresponding port at
the computer.
4. Connect the T-piece at the cable of the PCAN-Dongle to the
keyboard port.
5. Now reconnect the keyboard to the free end of the T-piece.
A configuration of the hardware is not needed. However, you
should check the settings for the parallel interface in the computer's
BIOS setup.
If the computer has a parallel interface with EPP as well as ECP
properties, the corresponding setting in the BIOS set-up should be
“ECP” (not “EPP” and not “EPP+ECP”). Although the extended
properties of the PCAN-Dongle usually will work with the last-
mentioned setting some systems may have problems with it.
Therefore the setting for the “pure” ECP mode should be preferred.
Further information about the different operating modes of the
PCAN-Dongle can be found in chapter 4.3

First Test
After turning on the computer the red LED at the PCAN-Dongle
must be permanently on. This indicates that the power supply for
the PCAN-Dongle is correct.
Attention! Don't remove PCAN-Dongle from the computer
while powered on (red LED on PCAN-Dongle is lit). Electronic
parts of the PCAN-Dongle or the computer's parallel interface
may be harmed.
2.2 Connecting a CAN Bus
A High-speed CAN bus (ISO 11898-2) is connected to the 9-pin
D-Sub port. The pin assignment corresponds to the CiA
recommendation DS 102-1.
Figure 1: Pin assignment HS-CAN
(view onto connector of the PCAN-Dongle)
2.3 5-Volt Supply at the CAN Connector
A 5-Volt supply can optionally be routed to pin 1 and/or pin 9 of the
CAN connector (PCAN-Dongle opto-decoupled: pin 1 only) by
setting solder bridges on the PCAN-Dongle PCB (Dongle case
opened). Thus devices with low power consumption (external
PCAN-Dongle – User Manual
8
transceivers or optocouplers, for example) can be directly supplied
via the CAN connector.
When using this option, the 5-Volt supply is directly connected to
the power supply of the PCAN-Dongle (coming from the computer)
and is not fused separately. The opto-decoupled model of the
Dongle contains an interconnected DC/DC converter. Therefore the
current output is limited to about 50 mA.
Attention! At this procedure special care is indispensable, since
there is a short circuit danger. The PCAN-Dongle could be des-
troyed and/or the power supply or electronics of the computer
or other components connected could be damaged.
Important note: PEAK-System Technik GmbH does not give
guarantee on damages which have resulted from application of
the option described in this section.
Do the following to set up a 5-Volt supply at the CAN connector:
1. In order to access the PCB, open the case of the PCAN-
Dongle by cautiously levering the latches on both sides (risk
of breakage!), e.g. with a flat tip screwdriver.
2. Set the solder bridges on the PCAN-Dongle PCB according
to the desired settings. Figure 2 and Figure 3 show the
possible positions of a solder bridge.

3. For reassembly place the PCB overhead onto the top part of
the case. Make sure that the cable is lying in the side cut-out
with the strain relief inside the case, and that the LED is
placed in the corresponding hole of the top part of the case.
4. Push the bottom part of the case onto the top part (the
latches click in).

3Software Setup
Under Windows a driver is needed that can access the PCAN-
Dongle and that provides the interface for Windows software.
Beside the mentioned device driver the CAN monitor PCAN-View
for Windows can also set up.
Do the following to setup the driver and, if applicable, additional
software:
1. Please make sure that you are logged in as user with
administrator privileges (not needed for normal use of the
PCAN-Dongle later on).
2. Insert the supplied CD-ROM into the drive of the computer.
Usually a navigation program appears a few moments later.
If not, start the file Intro.exe from the root directory of the
CD-ROM.
3. Navigate through the menus to the driver installation for the
PCAN-Dongle (English > Drivers > PCAN-Dongle). Click on
Install now afterwards. The setup program for the driver is
executed. Under Windows Vista you may need to confirm
the note about the execution with elevated rights.
4. Follow the instructions of the setup program.
