iPC-I 320 Manual, Version 2.8

1 Introduction

1.1 Overview

With the PC/CAN interface iPC-I 320 you have purchased a high-quality
electronic component which has been de veloped and ma nufactured accor ding
to the latest technological standards.

The aim of this manual is to help you familiarize yourself with your interfac e,
also referred to in the following as iPC-I 320. Please read this manual before
beginning with the installation.

The manual also describes, a mong other things, the hardware architec ture of
the interface, knowledge of which is required in order to create your own
applications on the interface.

If you are using the interface with the IXXAT VCI driver or other IXXAT software,
you can leave out Section 4. For information concerning the development of
own software running on the interf ace, please contact HMS or take a look on
the support area of the HMS homepage (www.ixxat.com

).

1.2 Features

The most important technical features are as follows:

• Design as ISA card (PC plug-in card, half length), PC/104 card or
AT96 / ISA96 card (Euro card format)

• 8-bit memory-mapped access (7 kbytes address space required)

• Base address can be set in the PC via DIP switch (in the range of C000h-

FE00h in 8k steps)

• PC interrupts can be set via jumpers (IRQ 3, 4, 5, 7, 9, 10, 11, 12, 14, 15)

• Microcontroller DALLAS 80C320 with 22.1184 MHz frequency (command

compatible with INTEL 8032)

• One or two CAN circuits via Philips SJA1000 and/or INTEL 82527 CAN
controller with 16 MHz frequency

• 4 kbyte dual-port RAM (DPRAM), 8 semaphore registers

• 32 kbyte EPROM (optional 64 kbyte EPROM)

• up to 63 kbytes code loadable

• up to 2x56 kbytes XDATA RAM operable

• two serial interfaces according to RS232C as an option

• CAN bus transceivers according to ISO/IS 11898 High Speed are on board

(electrically isolated as an option); alternatively, bus couplings can be
made via pin boards and plug-in cards

• optionally one or two CAN protective circuits on board

• downloadable (Intel HEX file format); max. 56 kbytes code

• various memory architectures (Harvard, von-Neumann)

• EMC compatible printed circuit design (4-layer multilayer)

2 Installation

2.1 Hardware Installation

For all work on the PC and interface, you must be static ally discharged. The
work must be carried out on an earthed, anti-static work-mat.

Carry out the following work in sequence:

(1) Establish a free memory segment on the PC of at least 8 kbyte in the

range < 1MB (ISA memory range) and a free IRQ. For this, read the
manual of your PC.

(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

determine a suitable plug-in space.

The interface is designed according to the PC-standard and can be easily

built into the computer. Do not use force when plugging in.
(5) Ensure that the interface is held safely in place in the PC.
(6) If your interface is assembled with 2 isolated CAN-circuits, you must fix

the additional slot plate and plug in the header on the interface (see

Section 3.2).
(7) Close the PC; the hardware installation is now completed.

2.2 Software Installation

To operate the interface, a driver is required.
For the installation of the CAN driver VCI under Win95/98/NT/2000, please read

the VCI installation manual.
