Overview
1.3 Description
1.3.1 Classical CAN
Figure 1: Block circuit diagram of Classical CAN versions
The CAN-PCI 402 is a PC board designed for the PCI bus that features one, two (CAN-PCI 402-2)
or four (CAN-PCI 402-4 2Slot) electrically isolated high-speed CAN interfaces according to ISO
11898-2. The Classical CAN versions support CAN bit rates up to 1 Mbit s. The independent CAN
interfaces are designed according to ISO 11898-1.
The CAN-PCI 402-4 2Slot comes with the standard version CAN-PCI 402-2 and an adapter board
(CAN-PCIe 402-Slot2) with two additional CAN interfaces.
These product versions are also available without electrical isolation.
Equipped with up to two CAN interfaces the board is available as low profile version CAN-PCI 402-
1-LP (optional CAN-PCI 402-LP-2 on request).
1.3.2 CAN FD
Figure 2: Block circuit diagram of CAN-PCI 402-2-FD
In the CAN FD version CAN-PCI 402-2-FD the board comes with two electrically isolated CAN FD
interfaces. The CAN-PCI 402-2-FD supports CAN bit rates from 10 kbit s up to 8 Mbit s. The
independent CAN FD interfaces are designed according to ISO 11898-1:2015.
CAN FD
Due to the higher bit rate in the data phase in combination with the increase of efficiency by a
higher number of user-data bytes, CAN FD offers a higher data throughput while maintaining the
qualities of the Classical CAN.

Overview
The CAN FD version CAN-PCI 402-2-FD is fully backwards compatible with CAN and can also be
used in Classical CAN applications.
INFO MATION
Every CAN FD controller is backward compatible to the Classical CAN protocol.
Classical CAN nodes and CAN FD nodes can communicate with each other as long as
the CAN FD frame format remains unused!
You can insert for example the CAN FD version CAN-PCI 402-2-FD in your Classical CAN
application if you want to replace a Classical CAN component. The CAN FD board automatically
communicates like a Classical CAN board (the existing program code can be used unchanged).
The CAN-PCI 402-2-FD has to communicate with the CAN nodes via Classical CAN frames,
because Classical CAN controllers do not tolerate CAN FD frames. All controllers have to use the
same Classical CAN Bitrate.
INFO MATION
During the initialisation of the CAN controller of the CAN FD boards the application
determines via software if the CAN FD boards communicate with Classical CAN or with
CAN FD.
See NTCAN-API Manual Part 1: “Application Developers Manual” for further information.
NOTICE
The system integrator has to verify that all CAN nodes on the bus are set to the same bit
rate!
If you work with a Classical CAN application and want to migrate to CAN FD in the future, you can
replace your Classical CAN nodes one after another until all CAN nodes are replaced by CAN FD
nodes.
1.3.3 General Properties
esdACC
The CAN or CAN FD interfaces are driven by the ISO 16845:2004 certified esdACC (esd advanced
CAN Core) implemented in an Intel® (formerly Altera®) FPGA.
For further information about esdACC see https: esd.eu en products esdacc.
CAN Data Management
The FPGA supports bus mastering (first-party DMA) to transfer data to the host memory. This
results in a reduction of the overall latency on servicing I O transactions in particular at higher data
rates and a reduced host CPU load.
Due to the usage of MSI (Message Signalled Interrupts) the CAN-PCI 402 can be operated for
example in Hypervisor environments.
The CAN-PCI 402 provides 64-bit high resolution hardware timestamp with bit time accuracy.
Software
The CAN layer 2 (NTCAN-API) drivers for Windows® and Linux® are included in the scope of
delivery. Additional CAN layer 2 (NTCAN-API) drivers for real-time operating systems (QNX®, RTX,
RTX64, VxWorks® and On Time RTOS-32) and the higher-layer protocol stacks (CANopen®,
J1939, ARINC825) can be ordered separately. See chapter “Software Support” on page 24 for
further information.
Additional free-of-charge esd CAN tools for Windows are downloadable from our website. The
tools offer efficient setup and analysis of Classical CAN applications and networks.

Therefore it is strongly recommended to keep the jumpers which are not needed for
CAN termination on the corresponding jumper depots CAN0 - CAN3!

Hardware Installation
4. Hardware Installation
NOTICE
ead the safety instructions at the beginning of this document carefully, before
you start with the hardware installation!
DANGE
Hazardous Voltage - isk of electric shock due to unintentional contact with
uninsulated live parts with high voltages inside of the system into which the CAN-PCI 402
is to be integrated.
→ Disconnect all hazardous voltages (mains voltage) before opening the system.
→ Ensure the absence of voltage before starting any electrical work
NOTICE
Electrostatic discharges may cause damage to electronic components.
→
→
To avoid this, please discharge the static electricity from your body by touching the
metal case of the PCI system before you touch the CAN-PCI 402.
Furthermore, you should prevent your clothes from touching the CAN-PCI 402,
because your clothes might be electrostatically charged as well.
Procedure:
1. Switch off your system and all connected peripheral devices (monitor, printer, etc.). Switch off
the connected CAN devices.
2. Discharge your body as described above.
3. Disconnect the power supply of the PC from the mains.

→
Disconnect all hazardous voltages (mains voltage) before opening the system.
If the system 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).
Ensure the absence of voltage before starting any electrical work
Cover or block off adjacent live parts.
4. Open the case.
5. Set the jumpers for the internal termination of the CAN (FD) interfaces according to your
needs (see page 17).
Make sure that the jumpers of the CAN interfaces which are not internally terminated are
kept on the corresponding depots.
6. Select an open PCI slot and remove the slot cover at the back of the PC.
The CAN module can be inserted into every PCI slot.
7. Insert the CAN-PCI 402 board into the selected PCI slot. Carefully push the board down until
it snaps into place.
8. Attach the CAN-PCI 402 board.

Hardware Installation
9. If you are installing the CAN-PCI 402-4 2Slot module with 4 CAN interfaces you have to
install the adapter board CAN-PCIe 402-Slot2 in the PCI slot next to the CAN-PCI 402-2
board. Connect the two boards with the included ribbon cable (see figure 4 on page 15) via
the 10-pin post connectors on the bard and on the adapter.
10. Close the system's case again.
11. Connect the CAN wire.
NOTICE
Please note that the CAN bus has to be terminated at both ends!
CAN-PCI/402-2(-FD):
The first CAN interface (CAN0) has to be connected via the lower DSUB connector (X600)
and the second CAN interface (CAN1) has to be connected via the upper DSUB connector
(X610). You will find a figure showing the connectors on page 14.
CAN-PCI/402-4/2Slot:
If you are installing a CAN-PCI 402-4 2Slot with adapter board, you have to connect the third
CAN interface (CAN2) via the lower DSUB connector (X400) of the adapter board and the
fourth CAN interface (CAN3) via the upper DSUB connector (X410) of the adapter board (see
figure 5, page 15).
efer to order information on page 41 to verify your hardware configuration.
For CAN-PCI/402 boards with electrical isolation:
If the integrated CAN termination of the CAN interface is not set via the jumpers, the interface
has to be terminated externally, read chapter “Correct Wiring of Electrically Isolated CAN
Networks“, from page 27.
For external termination esd offers suitable termination connectors for the CAN bus.
Additionally the CAN_GND signal has to be connected to earth at exactly one point.
A CAN participant with electrical connection to earth potential acts as an earth connection.
For CAN-PCI/402 boards without electrical isolation:
In order to avoid that possible lightning currents are discharged via the motherboard and thus
to avoid damage, CAN_GND is internally connected to the front panel and thus to earth
potential.
This does not supersede the external connection to earth potential!
NOTICE
Make sure that an external connection to the same earth potential is installed as near
as possible to the connector in the front panel before you go on with the installation.
Together with the internal earth connection this acts as a single earthing point.
12. Connect the system to mains again (mains connector or fuse).
13. Switch on the system and the peripheral devices.
14. End of hardware installation.
Continue with the software installation as described in the manual ‘NTCAN-API, Installation
Guide’.
