1. Overview
1.1 Module Description
Fig. 1.1.1: Block diagram of the module CAN-PCI/331
The module CAN-PCI/331 is a PC board designed for the PCI bus. It uses a 68331 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 compliant CAN interfaces allow a data transfer rate of 1 Mbit/s. Among many
other features, the bit rate can be set by software. The CAN interface is electrically isolated from
the other potentials by optocouplers and DC/DC converters.

2. Hardware Installation
Attention!
Electrostatic discharge may cause damage to electronic devices. In order to avoid this please
follow the instructions below before you touch the CAN module to discharge your personal
static electricity:
Switch off the power supply of your PC but leave the connector plug in the
socket.
Then touch the metal case of the PC to discharge the static electricty.
Furthermore you must avoid contact between your clothes and the CAN module.
Execute Hardware Installation:
1. Switch off the PC and all connected peripheral devices (monitor, printer, etc.). Switch off
the CAN devices of the net to which the CAN module is to be connected.
2. Discharge yourself as described above.
3. Disconnect the power supply of the PC from the mains.
4. Remove the PC cover.
Unfasten the mounting screws at the back of the PC and remove the cover.
5. Select an open PCI slot and remove the slot cover at the back of the PC. Unfasten the screw
which fixes the slot cover and retain it for fixing the module afterwards.
The CAN module can be inserted into every PCI slot. Be careful not to insert the board into
an ISA slot, because this can damage the PC and the board!
6. Insert the CAN module into the selected PCI slot.
Carefully push the board down until it snaps into place.
7. Attach the board.
Use the screw you removed from the slot cover in step 5.
8. Replace the PC cover.
Secure the cover with the screws you removed in step 4.
Installation
Installation and Technical Data CAN-PCI/331 Rev. 1.26
9. Connect the CAN wire.
Please note that the CAN bus has to be terminated at both ends! esd offers special T
connectors and terminator connectors. Additionally the CAN_GND signal has to be
connected to earth at exactly one point. For easier wiring the termination connectors are
equipped with an earth connector (4.8 mm fast-on, male).
A CAN participant without an electrically isolated interface acts as an earth connection.
The first CAN interface (CAN net 0) has to be connected via the lower DSUB connector
(X401) and the second CAN interface (net 1) has to be connected via the upper DSUB
connector (X400).
10. Reconnect the power supply of the PC.
11. Switch on the PC, the peripheral devices and the other CAN participants in any order.
12. End of hardware installation.
Continue with the software installation (for Windows NT or Windows 95 as described in
the manual ‘CAN-API, Monitor Program CAN Scope and Installation’).
