Safety Instructions
Safety Instructions
● When working with the CAN-ISA/ 1 follow the instructions below and read the manual carefully to
protect yourself from injury and the CAN-ISA/ 1 from damage.
● The device is a built-in component. It is essential to ensure that the device is mounted in a way that
cannot lead to endangering or injury of persons or damage to objects.
● Do not use damaged or defective cables to connect the CAN-ISA/ 1 and follow the CAN wiring
hints in chapter: "Correct Wiring of Electrically Isolated CAN Networks".
● In case of damages to the device, which might affect safety, appropriate and immediate measures
must be taken, that exclude an endangerment of persons and domestic animals and property.
● Current circuits which are connected to the device have to be sufficiently protected against
hazardous voltage (SELV according to EN 60950-1).
● The CAN-ISA/ 1 may only be driven by power supply current circuits, that are contact protected.
A power supply, that provides a safety extra-low voltage (SELV) according to EN 60950-1, complies
with this conditions.
● The device has to be securely installed in the PC before commissioning.
● Protect the CAN-ISA/ 1 from dust, moisture and steam.
● Protect the CAN-ISA/ 1 from shocks and vibrations.
● The CAN-ISA/ 1 may become warm during normal use. Always allow adequate ventilation around
the CAN-ISA/ 1 and use care when handling.
● Do not operate the CAN-ISA/ 1 adjacent to heat sources and do not expose it to unnecessary
thermal radiation. Ensure an ambient temperature as specified in the technical data.
DANGER
Hazardous Voltage - Risk of electric shock due to unintentional contact with uninsulated
live parts with high voltages inside of the system into which the CAN-ISA/ 1 is to be
integrated.

NO ICE
Electrostatic discharges may cause damage to electronic components.
To avoid this, perform the steps described on page 10 before you touch the CAN-
ISA/ 1, in order to discharge the static electricity from your body.
Qualified Personal
This documentation is directed exclusively towards personal qualified in control and automation
engineering. The installation and commissioning of the product may only be carried out by qualified
personal, which is authorized to put devices, systems and electric circuits into operation according to
the applicable national standards of safety engineering.

Overview
1. Overview
Figure 1: Block circuit diagram
The module CAN-ISA/ 1 is a PC board designed for the ISA bus (ISA 16 bit) with electrically
isolated high-speed CAN interfaces. It uses a 68 1 micro controller, which cares for the local CAN
data management. The CAN data is stored in the local SRAM. Security and consistency of data is
guaranteed up to 1 Mbit/s.
The ISO 11898-2 compliant CAN interfaces allow a data transfer rate of 1 Mbit/s. The CAN
interface is electrically isolated from the other potentials by optocouplers and DC/DC converters.
CAN layer 2 (NTCAN-API) software drivers are available for Windows, Linux, VxWorks and QNX.
The CANopen software package is available for Windows, Linux, VxWorks and QNX.

Read chapter “ .1 Before Starting Hardware Installation” on page 10, before you start
with the installation of the hardware!

Hardware Installation
3. Hardware Installation
To put the CAN-ISA/ 1 into operation, please follow the installation notes.
3.1 Before Starting Hardware Installation
Read the safety instructions at the beginning of this document carefully, before
you start with the hardware installation!
DANGER
Hazardous Voltage - Risk of electric shock due to unintentional contact with
uninsulated live parts with high voltages inside of the system into which the CAN-
ISA/ 1 is to be integrated. Disconnect all hazardous voltages (mains voltage) before
opening the system.
NO ICE
Electrostatic discharges may cause damage to electronic components.
→
→
To avoid this, please discharge the static electricity from your body by touching the
metal case of the PC before you touch the CAN-ISA/ 1.
Furthermore, you should prevent your clothes from touching the CAN-ISA/ 1,
because your clothes might be electrostatically charged as well.
NO ICE
During the installation it is necessary to set the interrupt line and it may be necessary
to change the ISA I/O port address of the board. The address is default factory set to
1E0...1E7 HEX at the jumper field JP100. The CAN-ISA/ 1 covers 8 data bytes.
Make sure, that there will be no address conflict with other ISA boards in the PC and
make sure, that there will be no conflict with other interrupts!
NO ICE
Make sure, that there will be no address conflict with other ISA boards in the PC and
make sure, that there will be no conflict with other interrupts!
Windows N Users:
To avoid system conflicts, you can control the used address ranges and the used interrupt
lines of your system. This can be done in Windows NT 4.0 by selecting Programs and then
selecting the folders Administrative Tools(Common) and WindowsNT Diagnostics. In the
dialogue box WindowsNT Diagnostics call Resources and there select I/O Port.
A list with the used addresses appears. Make sure that the default value of the CAN
module's address is placed in a free memory area. If it is not, compare the selectable
address ranges of the module (shown in fig. 4) with the free memory areas. Note one
selectable address area, and change the jumper settings during the hardware installation of
the CAN module afterwards.
In the same dialogue box call Interrupts. A list with the used interrupt lines appears. Note a
free interrupt, because you have to select an interrupt for the CAN module during the
software installation. The complete software installation sequence is described in the
software manual ‘NTCAN-API, Installation Guide’.
