Overview
1. Overview
Figure 1: Block circuit diagram
The CPCI-CAN/400-2 is a CompactPCI® board in 3U format, that features two electrically isolated
high-speed CAN interfaces according to ISO 898-2. CAN is driven by the esd Advanced CAN
Core (esdACC) CAN controller implemented in the Xilinx® Spartan® 3e FPGA.
The CPCI-CAN/400-2 provides high resolution hardware timestamps.
The CPCI-CAN/400-2 optionally features a PXI interface.
The signals TRG 0-7, CLK 0 and STAR are controlled via the FPGA. The signals LBL/LBR - 2
are looped through.
The PXI interface is available on request.

Hardware Installation
3. Hardware Installation
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 CPCI-CAN/400-2, in
order to discharge the static electricity from your body:



Switch off the power of your computer, but leave it connected to the mains until
you have discharged yourself (if applicable).
Please touch the metal case of the computer now to discharge yourself.
Furthermore, you should prevent your clothes from touching the computer,
because your clothes might be electrostatically charged as well.
Procedure:
. Switch off your computer and all connected peripheral devices (monitor, printer, etc.).
2. Discharge your body as described above.
3. Disconnect the computer 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. Open the case.
5. Insert the CPCI-CAN/400-2 board into a free CompactPCI slot in your computer.
6. Close the computer case again.
7. Fix the CPCI-CAN/400-2 board with the screws on the front panel.
8. Connect the CAN interfaces via the DSUB9 connectors in the front panel of the CPCI-
CAN/400-2 (see page 7).
Please note that the CAN bus has to be terminated at both ends! esd offers special T-
connectors and termination connectors. Additionally the CAN_GND signal has to be
connected to earth at exactly one point in the CAN network.
A CAN participant with a CAN interface which is not electrically isolated corresponds to the
grounding of the CAN-GND.

9. Connect the computer to mains again (mains connector or safety fuse).
0. Switch on the computer and the peripheral devices.
. End of hardware installation.
