PCAN-Dongle (ISO) – User Manual

1 Introduction

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 interface of an IBM compatible PC. It is especially suitable
for use with notebook computers since these usually don't have an
ISA or PCI slot. With the help of this adapter any PC can be linked to
a High-speed CAN (HS-CAN).

The so-called ISO version of the PCAN-Dongle additionally contains
a galvanic isolation. An isolation of up to 500 V between the PC and
the CAN parts of the adapter is achieved by use of a DC/DC
converter and an optocoupler.

Note: This manual refers to both the PCAN-Dongle standard
version and the PCAN-Dongle ISO with galvanic isolation.
Differences at use and at the technical specifications are
mentioned accordingly in this manual.

PCAN-Dongle (ISO) – User Manual

2 Hardware Installation

2.1 Connecting to the PC

1. Make sure that the PC is turned off.

2. Connect the PCAN-Dongle with the wider port (25 pins) to
the free parallel port at the PC.

3. Pull the keyboard connector from the corresponding port at
the PC.

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 PC's BIOS
setup.

If the PC 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

PCAN-Dongle (ISO) – User Manual

First Test

After turning on the PC the red LED at the PCAN-Dongle must be
permanently on. This indicates that the power supply for the PCAN­Dongle is correct.

Attention! Don't remove PCAN-Dongle from the PC while
powered on (red LED on PCAN-Dongle is lit). Electronic parts of
the PCAN-Dongle or the PC's parallel interface may be harmed.

2.2 Connecting a HS-CAN

A CAN is connected to the 9-pin Sub-D port on the PCAN-Dongle.
The pin assignment corresponds to the CiA recommendation DS
102-1.

Figure 1: Pin assignment HS-CAN

(view onto male 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 ISO: pin 1 only) by setting solder
bridges on the PCAN-Dongle PCB (Dongle case opened). Thus
devices with low power consumption (external transceivers or
optocouplers, for example) can be directly supplied via the CAN
connector.

7

PCAN-Dongle (ISO) – User Manual

When using this option, the 5-Volt supply is directly connected to
the power supply of the PCAN-Dongle (coming from the PC) and is
not fused separately. The ISO version of the Dongle contains an
interconnected DC/DC converter. Therefore the current output is
limited to about 50 mA.

Attention! At this procedure a special care is indispensable
since there is a short circuit danger. The PCAN-Dongle could be
destroyed and/or the power supply or electronics of the PC 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.

Procedure:

1. In order to access the PCB, open the case of the PCAN­Dongle 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.

6 Frequently Asked Questions

(FAQ)

Question Answer

In the PC's BIOS setup the
parallel port setting shows
ECP but the PCAN-Dongle
works with the EPP mode.
Is this correct?

Can a printer still be
connected to the PCAN­Dongle?

Is it possible to supply the
PCAN-Dongle PS/2 also via
the computer's mouse
connector?

I have problems running
the PCAN-Dongle under
Windows 2000/XP.

Yes, it is. The naming of the
operating mode EPP of the PCAN­Dongle has historical causes. The
parallel interface at the PC went
through various developments in the
nineties. Only the EPP extension
existed during the time, when the
PCAN-Dongle arose. With version 1.9
the EPP extension already had
similarities to the ECP extension,
which is usually used in PCs today.
The name of the operating mode EPP
was kept for the PCAN-Dongle.

No. The PCAN-Dongle doesn't offer
any possibility to connect through the
parallel interface for the printer. The
PCAN-Dongle Pro, having this
functionality integrated, isn't sold by
PEAK-System anymore.

Yes.

The driver files PEAKCAN.SYS and
PCAN_DNG.SYS must be available at
least in version 2.30. You can
determine the currently used driver
version e.g. with the About dialog
box in PCAN-View (menu command
Help | About).
