Introduction
1 Introduction
1.1 Overview
Congratulations on your purchase of the IXXAT PC/CAN interface PC-I 03, a high-
quality electronic component developed and manufactured according to the lat-
est technological standards.
This manual is intended to familiarize you with your interface, also referred to in the
following as PC-I 03. Please read this manual before beginning with the installation.
The manual describes, among other things, the hardware architecture of the interface,
knowledge of which is required for creating your own drivers.
If using the interface with the IXXAT driver VCI or other IXXAT software, you do not
need to read sections 4 and 5.
1.2 Features
The main technical features are as follows:
• 8 bit AT slot interface
• Independent operation of two separate CAN lines each with a CAN controller Philips
SJA1000 or Intel 82527 possible
• CAN controller with 16 MHz clock
• Each CAN controller can be allocated a separate PC interrupt line via jumper field for
connection to the PC interrupt system. The following 10 interrupt lines are available:
IRQ 3, 4, 5, 7, 9, 10, 11, 12, 14 and 15
• Support of shared interrupts
• Fast access to the CAN controllers due to direct memory mapping
• Support of the READY line (can be switched off via DIP switch)
• Basic addresses beginning with C000H can be set in 4 k steps via DIP switch, occu-
pying 4 kbytes of address space
• Bus interface according to ISO 11898-2 on-board, galvanically isolated as an option
• Optional CAN protective circuit on-board
• CAN connection via 9-pin Sub-D connector / Sub-D socket
• Pin allocation according to CiA/DS-102

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, antistatic work mat.
Take the following steps in sequence:
(1) Find a free memory segment on the PC of at least 4 kbytes in the range
< 1MB (ISA memory range) and a free IRQ for each CAN controller. Use the
manual of your PC for this.
(2) Set this memory segment and the IRQ on the interface, as described in sec-
tion 3.1.
(3) Switch the PC off and remove the mains plug.
(4) 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 stan-
dard and can easily be built into the computer. Do not use force when plug-
ging in.
(5) Make sure the interface sits tightly in the PC.
(6) If your interface is equipped with 2 separate CAN lines, you must fit the additional
slotplate and plug in the header on the interface (see section 3.2).
(7) Close the PC; the hardware installation is now complete.
2.2 Software installation
A driver is required to operate the interface. For installation of the CAN driver VCI under
Windows, please refer to the VCI installation manual.

Configuration
3.1.2 Setting the PC interrupt
The required interrupt can be set separately for each CAN controller. The Interrupt num-
ber and the number of the associated CAN controller are located on the board under
the two jumper boards. The required PC interrupt is set with the corresponding jumper
board by closing the jumper pair of the required IRQ.
Only one interrupt may be selected for each CAN controller. If no interrupt is required,
no pin of the corresponding jumper board may be bridged. The factory setting of the
interface is IRQ5 for the first CAN controller and (if present) IRQ10 for the second CAN
controller (see Fig. 3-1). It must be ensured that no other system components occupy
the selected interrupt, except for system components that work with shared interrupts.
3.1.3 READY signal
With assembled Intel 82527 the READY signal can be supported with the DIP switch
SW1-7. For this the switch is set to OFF (factory setting: Switch SW1-7 set to ON). The
READY signal is used when an error occurs during a read accesses on the Intel CAN
controller (wrong index contents).
3.1.4 Supplying voltage via CAN connector
VCC or GND can be connected to the 9-pin Sub-D connector/socket with the soldered
jumpers JP3, JP4, JP5, JP32, JP33 and JP36. For this the jumpers listed in the following
table must be closed. The soldered jumpers are located on the back of the PC-I 03.

9 - VCC open JP4 JP36
Caution: This voltage may be loaded with maximum 100 mA.
With galavanically isolated bus interfaces, GND and VCC are also galvanically isolated
from the power supply of the PC.
3.1.5 Bus terminal
Bus terminal resistors are assembled on the PC-I 03 for the first and second CAN line
with 120 Ohms each. The bus terminal for the first CAN line is connected with the sol-
dered jumper JP6, for the second CAN line with JP7. The bus is terminated between
CAN-Low and CAN-High. When delivered, the bus terminals are not active.
3.2 Design of the CAN connectors
Two isolated high-speed bus interfaces according to ISO 11898-2 can be mounted on
the interface.
The signals of the first bus interface are connected to the 9-pin Sub-D connector/socket.
If the second bus interface is assembled, the signals for the CAN bus of the second bus

Configuration
interface are connected to the header. A separate slotplate with two Sub-D-9 connec-
tors is connected to the header via a 9-pin ribbon cable with the header of the interface.
All pin allocations of the Sub-D connectors conform to the CiA specification CiA/DS-102.
As a further option, a version without bus connection on the interface is available. In
this case the signals are led out on two connector boards each (JP14/JP15 for the
first CAN line, JP24/JP25 for the second CAN line). This enables the implementation of
alternative bus connections.
A CAN protective circuit, consisting of a special CAN coil is also available as an option.
The circuit suppresses faults and short spikes on the CAN lines.

tor/socket.

3.2.2 Connection between CAN controllers and bus interfaces
For the implementation of specific bus interfaces, the connections JP14, JP15, JP24 and
JP25 are available. These are only required if the interface is designed without on-board
bus connection.
The signals of the CAN controllers 1 and 2 are connected to JP14 and JP24 respectively.

4.1.1 Access to CAN controllers
Up to two CAN controllers either of type Philips SJA1000 and/or Intel 82527 can be as-
sembled on the interface.
The first CAN controller is displayed in the range from 0000h to 00FFh, the second CAN
controller in the range from 0200h to 02FFh from the basic address of the board. With
access to the individual memory range, the corresponding CAN controller is automati-
cally selected. The basic address can be configured as described in section 3.1.1.
The exact index description of the SJA1000 and of the Intel 82527 is found in the corre-
sponding data sheets of Philips and Intel (Web addresses in Appendix).
The Output Control Register of the CAN controllers must be loaded with the value 5Eh.
4.1.2 Resetting the CAN controllers from the PC
By writing any value to an address of the reset range (0100h to 01FFh for the first CAN
controller and 0300h to 03FFh for the second CAN controller), a hardware reset is car-
ried out on the corresponding CAN controller.
4.2 Triggering an interrupt on the PC
The CAN controllers can trigger interrupts on the PC. For configuration of the interrupts,
see section 3.1.2
