Safety Instructions
● When working with the CAN-PCIe/200 follow the instructions below and read the manual carefully to
protect yourself from injury and the CAN-PCIe/200 from damage.
● The de ice is a built-in component. It is essential to ensure that the de ice is mounted in a way that
cannot lead to endangering or injury of persons or damage to objects.
● Do not use damaged or defecti e cables to connect the CAN-PCIe/200 and follow the CAN wiring
hints in chapter: "Correct Wiring of Electrically Isolated CAN Networks".
● In case of damages to the de ice, 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 de ice ha e to be sufficiently protected against
hazardous oltage (SELV according to EN 60950-1).
● The CAN-PCIe/200 may only be dri en by power supply current circuits, that are contact protected.
A power supply, that pro ides a safety extra-low oltage (SELV) according to EN 60950-1, complies

1.1 Description of the Module
Figure 1: Block circuit diagram of CAN-PCIe/200
The CAN-PCIe/200 is a passi e 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 effecti e CAN bit rate alue may be limited by the performance of the host CPU,
because this is a passi e CAN module without a microcontroller on board.
The CAN interface is electrically isolated from the other potentials by optocouplers and DC/DC-
con erters.
The CAN-PCIe/200 is equipped with four LEDs in the front panel.

Hardware Installation
2. Hardware Installation
N TICE
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 li e parts with high oltages inside of the system into which the CAN-
PCIe/200 is to be integrated.
→ Disconnect all hazardous oltages (mains oltage) before opening the system.
→ Ensure the absence of oltage before starting any electrical work.
N TICE
Electrostatic discharges may cause damage to electronic components.
→
→
To a oid this, please discharge the static electricity from your body before you touch
the CAN-PCIe/200.
Furthermore, you should pre ent your clothes from touching the CAN-PCIe/200,
because your clothes might be electrostatically charged as well.
Procedure:
1. Switch off your system and all connected peripheral de ices (monitor, printer, etc.). Switch off
the connected CAN de ices.
2. Discharge your body as described abo e.
3. Disconnect the system from the mains.
Make sure that no risk arises from the system into which the CAN-PCIe/200 shall be
inserted.
DANGER
Hazardous Voltage
Risk of electric shock due to unintentional contact with uninsulated li e parts with
high oltages.
→
→
→
→
Disconnect all hazardous oltages (mains oltage) before opening the system.
If the system does not ha e a flexible mains cable, but is directly connected to
mains, disconnect the power supply ia the safety fuse and make sure that the fuse
cannot switch on again unintentionally (i.e. with caution label).
Ensure the absence of oltage before starting any electrical work.
Co er or block off adjacent li e parts.
4. Open the case if necessary.
5. Select an open PCI Express slot and remo e the slot co er at the back of the PC.
Unfasten the screw which fixes the slot co er and retain it for fixing the module afterwards.
The CAN module can be inserted into e ery PCI Express slot.
6. Insert the CAN-PCIe/200 board into the selected PCI Express slot. Carefully push the board
down until it snaps into place.
7. Attach the board.
Use the screw you remo ed from the slot co er in step 5.
8. Close the system's case again.
