1. Overview
1.1 Description of the Module
Fig. 1.1: Block circuit diagram of CAN-PCIe/200
The CAN-PCIe/200 is a passive CAN interface board for PCI Express with one, or optionally two CAN
interfaces.
The ISO 11898-2 CAN interface allows a maximum data transfer rate of 1 Mbit/s. Among many other
features of the CAN interfaces, the baud rate can be set by software.
The maximum effective CAN bit rate value may be limited by the performance of the host CPU,
because this is a passive CAN module without a microcontroller on board.
The CAN interface is electrically isolated from the other potentials by optocouplers and DC/DC-
converters.
The CAN-PCIe/200 is equipped with four LEDs in the front panel.

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 electricity.
@Furthermore you must avoid contact between your clothes and the CAN module.
Procedure:
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 PCIe 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 PCIe 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.

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 (X400)
and the second CAN interface (net 1) has to be connected via the upper DSUB connector (X410).
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 as described in the manual “CAN-API, Part 2: Installation
Guide".
