Overview
1. Overview
1.1 Module Descri tion
Figure 1: Block circuit diagram
The CAN-PCI/405 is a PC board designed for the PCI bus that supports up to four independent
CAN interfaces. In the CAN-PCI/405-2 version two interfaces are placed directly on the board.
Furthermore, in the CAN-PCI/405-4 version two additional interfaces are placed on an adapter
board.
The IBM PowerPC 405GP with 200 MHz enables a performance of up to 375 MIPS. The board is
equipped with 16 Mbyte SDRAM and 1 Mbyte Flash.
The CAN-PCI/405 produces hardware-generated timestamps with a resolution of 1 μs for all CAN
messages.
The CAN-PCI/405-2 provides two and the CAN-PCI/405-4 four ISO 11898 compliant CAN
interfaces based on SJA1000 CAN controllers. The CAN interfaces allow a data transfer rate of 1
Mbit/s. The interfaces are electrically isolated from the other potentials.

Hardware Installation
2. Hardware Installation
2.1 Procedure
Read the safety instructions at the beginning of this document carefully, before
you start with the hardware installation!
Danger!
Electric shock risk. Never carry out work while power supply voltage is switched on!
Attention !
Electrostatic discharges may cause damage to electronic components. To avoid this,
please perform the following steps before you touch the module, in order to discharge
the static electricity from your body
→
→
→
Switch off the power of your PC, but leave it connected to the mains until you
have discharged yourself.
Please touch the metal case of the PC now to discharge yourself.
Furthermore, you must avoid contact between your clothes and the CAN-PCI/405.
Procedure:
1. Switch off your computer 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 your body as described above.
3. Disconnect the power supply of the PC from the mains.
If the computer does not have a flexible mains cable, but is directly connected to mains,
disconnect the power supply via the safety fuse and make sure that the fuse cannot switch
on again unintentionally (i.e. with caution label).
Danger!
Never carry out work while power supply voltage is switched on!
4. Remove the PC cover.
For further information on this see the manual of your PC.
5. Select an open PCI slot and remove the slot cover of the PC.
The CAN module can be inserted into every PCI slot. Be careful not to insert the board into a
slot of another slot type, because this might 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.
8. If you are installing the CAN-PCI/405-4 module with 4 CAN interfaces you have to install the
adapter board in the PCI slot next to the CAN-PCI/405. Connect the two boards with the
included ribbon cable. The cable connectors are reverse-connect protected.

Hardware Installation
9. Replace the PC cover.
10. 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 (CAN0) has to be connected via the lower DSUB connector (X1000)
and the second CAN interface (CAN1) has to be connected via the upper DSUB connector
(X1010) of the CAN-PCI/405.
If you are installing a CAN-PCI/405-4 with four CAN interfaces, you have to connect the third
CAN interface (CAN2) via the lower DSUB connector of the adapter board and the fourth
CAN interface (CAN3) via the upper DSUB connector of the adapter board. You will find a
figure showing the connectors on page 11.
11. Reconnect the power supply of the PC.
12. Switch on the PC, the peripheral devices and the other CAN participants in any order.
13. End of hardware installation.
