Introduction
1 Introduction
1.1 Overview
Congratulations on your purchase of the IXXAT-PC-CAN-interface PC-I 04/PCI, a
high-quality electronic component developed and manufactured according to the
latest technological standards.
This handbook is intended to familiarize you with your interface, also referred to
in the following as PC-I 04/PCI. Please read this handbook before beginning with
the installation.
Among other things, the handbook describes the hardware architecture of the
interface, knowledge of which is necessary for creating your own drivers.
If you are using the interface with the IXXAT-driver VCI or other IXXAT-software,
you can leave out Sections 4 and 5.
1.2 Features
The most important technical features are as follows:
• Constructed as PCI-plug-in card
• 32 bit memory-mapped access (1024 byte storage space and 128 byte I/O
address space are required for the CAN controller)
• Basic address and interrupt via plug’n’play PCI-Bios
• One or two CAN-circuits with Philips SJA1000 with 16 MHz cycle time
• CAN-bus connection according to ISO 11898-2 High Speed on board (as an
option galvanically isolated)
• Bus connection carried out separately for each CAN-controller
• Option of one or two CAN-protective circuits on the board (CAN-reactor to
suppress faults and short spikes on the CAN-leads)
• Pin assignment according to CiA/DS-102
• Electro-magnetically compatible PCB design (4-layer multilayer)

Installation
2 Installation
2.1 Hardware installation
For all work on the PC and interface, you must be statically discharged. Work
must be carried out on an earthed, anti-static work mat.
Take the following steps in sequence:
(1) Switch the PC off and remove the mains plug.
(2) Open the PC according to the instructions of the PC manufacturer and find a
suitable place to plug in.
The interface is designed according to the PC-standard and can easily be
built into the computer. Do not use force when plugging in.
(3) Make sure the interface sits tightly in the PC.
(4) If your interface is equipped with 2 isolated CAN-circuits, you must fix the
additional slot plate, and plug in the header on the interface (see Section
3.2).
(5) Close the PC; the hardware installation is now complete.
2.2 Software installation
A driver is required in order to operate the interface.
For the installation of the CAN driver VCI, please read the VCI-installation hand-
book.

3.1.1 Supplying voltage via CAN-plug
With the solder jumpers JP3, JP4, JP5, JP32, JP33 and JP36, VCC (5 V) or GND can
be connected to the CAN-plugs of the two CAN-circuits. For this, the jumpers
given in the following table are to be connected. The solder jumpers are on the
solder side of the PC-I04/PCI.

Caution: This voltage may be loaded with maximum 100 mA.
If the bus interface is galavanically isolated, GND and VCC are also galvanically
isolated from the power supply of the PC.

Configuration
3.1.2 Connection to ground for measuring purposes
There is a connection on the PC-I 04/PCI for a ground pin. The abbreviation GND
is marked on the board next to the drill hole.
3.2 Design of the CAN-plugs
Two isolated high-speed bus attachments according to ISO 11898-2 can be
mounted on the interface.
The signals of the first bus connection are connected to the 9-pin Sub-D-plug/-
socket X1/X2.
If the second bus connection is printed, the signals for the CAN-bus of the sec-
ond bus connection are connected to the header X3 and a separate slot plate
with two sub-D9-plugs are supplied with the interface for the bus connection of
the second CAN-controller. This slot plate is connected to the header of the inter-
face via a 9-pin ribbon cable.
3.3 Pin assignment
The following plugs are present on the interface:
