1 Introduction
The PCAN-PC/104 card enables the connection of one or two CAN
networks to a PC/104 system. Multiple PCAN-PC/104 cards can
easily be operated using interrupt sharing.
The card is available as a single or dual-channel version. The opto-
decoupled versions also guarantee galvanic isolation of up to 500
Volts between the PC and the CAN sides.
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.
Device drivers exist for different operating 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-PC/104 card.

2 Configuration and
Installation
This chapter covers the configuration, the software setup for the
PCAN-PC/104 card under Windows, and the card installation in the
computer.
2.1 Configuring the Card
Before installing the PCAN-PC/104 card into the computer you may
need to configure it. For each CAN channel an interrupt (IRQ) and an
I/O address range is set for operation in the computer.
At delivery the PCAN-PC/104 card has the following default settings:
CAN channel IRQ I/O address range Comment
1 10 300h – 31Fh
2 5 320h – 33Fh Dual Channel model only
Tip: If the given resources are not permanently allocated by
other devices, you can skip the configuration and directly
continue with the following manual section 2.2.
For a configuration differing from the default settings you need to
set jumpers on the PCAN-PC/104 PCB according to the following
explanations.
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the PCAN-PC/104 card. Take precautions to
avoid ESD when handling the card.

PCAN-PC/104 – User Manual

2.1.1 Interrupt
An interrupt (IRQ) must be assigned to each CAN channel. This is
done with a single jumper on jumper field JP1 for CAN channel 1
and jumper field JP2 for CAN channel 2 (latter refers only to the
Dual Channel model). The PCAN-PC/104 card supports the inter-
rupts 3, 4, 5, 7, 10, 11, 12, and 15. The default setting at delivery for
CAN channel 1 is interrupt 10, for CAN channel 2 interrupt 5.
Figure 1: Position of the jumper fields for setting the interrupts,
JP1 for CAN channel 1 (lower jumper field),
JP2 for CAN channel 2 (upper jumper field,
Dual Channel model only)
It is possible to share the same interrupt between two existing CAN
channels. Therefore, you can configure the same interrupt when
using two PCAN-PC/104 cards in the same computer.
Tip: We suggest to configure different interrupts as long as
resources allow it and use interrupt sharing only if this is not
the case.

PCAN-PC/104 – User Manual

2.1.2 I/O Address Range
Each CAN channel must be assigned to an unique I/O address range
in the computer. An address space from 200h up to 39Fh and 3E0h
to 3FFh (h = hexadecimal) is available. PCAN-PC/104 uses 32 addres-
ses beginning from the configured base address. The configuration
is done on jumper field JP3 for CAN channel 1 and jumper field JP4
for CAN channel 2 (latter refers only to the Dual Channel model).
One or several jumpers are needed for each jumper field.
Figure 2: Position of the jumper fields for setting the I/O base addresses,
JP3 for CAN channel 1 (left jumper field),
JP4 for CAN channel 2 (right jumper field, Dual Channel model only)
The following table shows the possible settings. The X stands for a
set jumper. The default settings at delivery for CAN channels 1 and
2 are highlighted.

PCAN-PC/104 – User Manual
13
Node: The CAN device drivers Non-Plug-and-Play is only
available under 32-bit Windows. PCAN-PC104 does not work
under 64-bit Windows.
6. Follow the further instructions.
2.3 Installing the Hardware
Do the following to install card into the PC/104 stack:
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the card. Take precautions to avoid ESD.
1. Shut down the computer.
2. Disconnect the computer from the power supply.
3. Plug the PCAN-PC/104 card onto a PC/104 connector.
4. Interconnect the connector for each CAN channel on the
PCAN-PC/104 card (see Figure 4) with the CAN connector of
the slot bracket using the attached flat cable.
5. Reconnect the power supply of the computer.
Note: Before switching on the computer, please follow the pro-
cedure for modifying the computer's BIOS settings described in
the following section.

2.4 Modifying the Computer's BIOS Settings
To ensure a flawless operation of the PCAN-PC/104 card it is neces-
sary that you adjust settings in the BIOS setup of the computer:
Indicate used interrupts
Deactivate the APIC mode
Note: Due to a diversity of existing BIOS setup versions for
computers we cannot give detailed instructions here. Instead
we indicate common setting names.
In order to know how to start the computer's BIOS setup please
consult the corresponding documentation. Usually you can enter
the BIOS setup by pressing the Del or F2 key shortly after
switching on the computer.
2.4.1 Indicating Used Interrupts
By indicating the interrupts that are set on the PCAN-PC/104 card,
you avoid that the corresponding resources are automatically
assigned to other devices and that this results in conflicts.
In the BIOS setup itself you can often find the settings for the
interrupts under a menu item containing the text PnP. For the
interrupt(s) used by PCAN-PC/104 change the setting to Reserved or
Legacy ISA.

PCAN-PC/104 – User Manual
16
2.4.2 Deactivating the APIC Mode
Note: Do not mix up APIC with ACPI.
The APIC mode is a certain type of interrupt management in a
computer.
If the APIC mode is active in your computer, you must deactivate it
so that the PCAN-PC/104 card can work properly with interrupts.
Do the following to determine in Windows if the APIC mode is
active:
Open the Windows Device Manager.
1. Select the menu entry View > Resources by type.
2. Open the branch of Interrupt request (IRQ).
If entries with interrupt numbers greater than 15 are listed,
the APIC mode is active and you must deactivate it.
Do the following to deactivate the APIC mode:
Important note: When you deactivate the APIC mode in the
BIOS setup, it may happen that you must reinstall Windows
afterwards, because it cannot start anymore due to the low-
level setting.
Restart the computer and switch to the BIOS setup.
1. Search for the APIC setting and deactivate it.
2. Save the changes in the BIOS and quit the BIOS setup.
3. If Windows doesn't start properly, reinstall it or perform a
repair installation.

3 Connecting the CAN Bus
3.1 Connection over D-Sub Connector
A High-speed CAN bus (ISO 11898-2) is connected to the 9-pin
D-Sub connector. The pin assignment corresponds to the
specification CiA® 303-1.
Figure 5: Pin assignment High-speed CAN
(view onto connector of the slot bracket)
Low power devices (e.g. bus converters) can be supplied directly
with 5 volts over pin 1 and/or pin 9 of the CAN connector. Pin 1
and/or pin 9 are not in use at the delivery state. For more
information see the next section 3.2.

PCAN-PC/104 – User Manual
18
The pin assignment between the D-Sub port and the 10-pin connec-
tor on the PCAN-PC/104 card is as follows:
Figure 6: Numbering at the 10-pin connector
Pin Assignment Assignment
D-Sub
1 +5 V (optional) 1
2 GND 6
3 CAN_L 2
4 CAN_H 7
5 GND 3
6 not connected 8
7 not connected 4
8 +5 V (optional) 9
9 not connected 5
10 not connected
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).

3.1.1 Slot Bracket with D-Sub Connectors
Figure 7: Single channel slot bracket
Figure 8: Dual channel slot bracket
To connect a CAN bus to the PCAN-PC/104 card, use the supplied
slot brackets. After you have connected the cables from the slot
bracket with the 10-pin sockets, you can connect the CAN busses
with the D-Sub sockets.

3.2 Voltage Supply of External Devices
External devices with low power consumption (e.g. bus converters)
can be directly supplied via the CAN connector (independently for
each connector on the Dual Channel versions). With a solder bridge
per CAN channel on the PCAN-PC/104 board, a 5-Volt supply can
optionally be routed to pin 1 and/or pin 9 of the D-Sub connector.
The opto-decoupled models of the card contain an interconnected
DC/DC converter. Therefore, the current output is limited to about
50 mA.
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.
Set the solder bridge(s) on the card according to the desired
settings.
Figure 9 shows the solder field positions on the card. The table
below contains the possible settings.
