1 Introduction
1.1 Overview
Congratulations on your purchase of the PC/CAN Interface PC-I 04/104, a highquality electronic component developed and manufactured according to the
latest technological standards.
This manual is intended to familiarize you with your interface, also referred to in
the following as PC-I 04/104. Please read this manual before beginning with the
installation.
1.2 Features
The main technical features are as follows:
• Constructed as an 8 bit PC/104 interface
• Memory-mapped access: possible basic addresses are in the range from C000H
to FFC0H (See also section 3.1.1). The basic address can be set in 1k steps via
DIP switches. The interface occupies 1 kByte address space
• One or two CAN lines each with Philips SJA1000 controller; 16 MHz clock
• Each CAN controller can be allocated to a separate PC interrupt line via a jumper
field. The following 11 interrupt lines are available:
3, 4, 5, 6, 7, 9, 10, 11, 12, 14 and 15
• CAN bus interface according to ISO 11898-2 high-speed on-board (galvanically
isolated as an option)
• Separate bus interface for each CAN controller

2 Installation
2.1 Software Installation
A driver is required in order to operate the interface.
For the installation of the CAN driver VCI, please refer to the VCI installation manual.
2.2 Hardware Installation
For all work on the PC and i nterface, you must be staticall y discharged. Work
must be carried out on an earthed, anti-static work mat.
Take the following steps in sequence:
(1) Find a free memory segment on the PC of at least 1 kByte in the range
< 1MB (ISA memory range) and a free interrupt (IRQ). Refer to the manual
of your PC for this.
(2) Set this memory segment and the IRQ on the interface, as described in
section 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/104 standard and can easily be
installed. Do not use force when plugging in.
(5)
Make sure the interface sits tightly in the PC.
(6)
Close the PC; the hardware installation is now complete.

3.1.1 Setting the Basic Address
The DIP switches A10 to A17 are used to set t he basic addr ess. The foll owing
table 3-1 shows which addresses are decoded for this with the aid of the
example address D8C00h. The addresses with a white background indicate the
setting range by me ans of DIP switches , the addresses marked with X cannot
be influenced.
Beginning with the set basic address, the PC/CAN interface occupies an
address space of 4 kByte. In this address range the interface can be addressed
as a normal RAM. No othe r interface may be prese nt in the selected memor y
range.

3.1.2 Setting the PC Interrupt
The required interrupt can be set separately for each CAN controller via the
jumper boards JP 10 (for CAN 1) and JP 11 (for C AN2). To set an interrupt o n
the interface, the corresponding jumper must be closed. Only one interrupt may
be selected for each CAN controller. If no interrupt is required, no jumper of the
corresponding jumper board may be closed. The factory setting of the interface
is IRQ 5 for the first CAN controller and (if present) IRQ 7 for the second CAN
controller.
3.1.3 Setting the Int err upt Mode
The interface PC-I 04/104 pro vides three different types of int errupt triggering.
These can be set for CAN1 via the jumpers JP12, JP14 and JP15 and (if
present) for CAN2 via JP13, J P20 and JP21. The jumper settings are li sted in
the following table. The default setting is marked with def. = default setting.

Note on use of Shared High interrupt triggering:
With interrupt triggering Shared High, an IRQ line is used by several interrupt sources (e.g.
first CAN controller, second CAN controller, further ISA boards). The PC/104 specification
stipulates that the interrupt line must have only one 1 k Ohm resistor betw een ground and IRQ
line (see PC/104 specification Appendix C.3). A 1 k Ohm resistor can be connected via JP14
(CAN1) or JP20 (CAN2). If this trigger type is used with a PC-I 04/104 interface equipped wi th
two CAN controllers, this means that either jumper JP14 or JP20 is to be closed.

3.1.4 Providing Power Suppl y via CAN Connector
VCC (5 V) or GND can be connected to the 10 pin header with the soldered
jumpers JP2, JP3, JP7 and JP8. For this, the jumpers listed in the following table
must be closed. The soldered jumpers are located on the back of the PC-I
04/104 (Fig. 3-2).

3.2 Design of the CAN Connectors
Two separate high-speed bus interfaces according to ISO 11898-2 can be
mounted on the interface.
The signals of the first bus i nterface are c onnected to the 10 pin header X1. If
the second bus interface is assembled, the signals for the CAN bus of the
second bus interface are connected to the header X2.

Bus termination resistor s are assembled on the PC-I 04/104 board for the fir st
and second CAN lines with 120 Ohms each, which can be connected for the
first CAN line via the soldered jumper JP5 and for the second CAN line with JP4
(see Fig. 3-2). The bus is terminated with a 120 Ohm resistor between CAN low
and CAN high. When delivered, the jumpers for termination are not active.

4.1.1 Access to CAN Controllers
Up to two CAN controllers either of type Philips SJA1000 can be assembled 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 plus basic address of
the board. With access to the individual memory range, the corresponding CAN
controller is automatically selected. The basic address can be configured as
described in section 3.1.1.
The Output Control Register of the CAN controller must be loaded with the value
DEh or 5Eh.
The exact index des cription of the SJA10 00 is give n in the cor responding data
sheets of Philips (see Appendix C).
4.1.2 Resetting the CAN Controllers from the PC
By writing a random value to an addre ss of the Reset range (0100h to 01FFh
for the first CAN controller and 0300h to 03FFh for th e seco nd CAN contr oller),
a hardware reset is carried out on the corresponding CAN controller.
4.2 Triggering an Interrupt on the PC
The CAN controllers can trigger interrupts on the P C. For configuration of the
interrupts, see section 3.1.2
