3Connecting the CAN Bus
3.1 D-Sub connector
A High-speed CAN bus (ISO 11898-2) is connected to the 9-pin
D-Sub connector. The pin assignment for CAN corresponds to the
specification CiA® 102.
Figure 2: Pin assignment High-speed CAN
(view onto a male D-Sub connector on the PCAN-cPCI card)
With the pins 1 and 9 devices with low power consumption (e.g. bus
converters) can be directly supplied via the CAN connector. At deli-
very these pins are not assigned. You can find a detailed description
in the following section 3.2.
Tip: You can connect a CAN bus with a different transmission
standard via a bus converter. PEAK-System offers different bus
converter modules (e.g. PCAN-TJA1054 for a Low-speed CAN
bus according to ISO 11898-3).

3.2 Supplying External Devices via the CAN
Connector
A 5-Volt supply can optionally be routed to pin 1 and/or pin 9 of a
D-Sub connector (independently for each connector) by setting
solder bridges on the PCAN-cPCI card. Thus devices with low power
consumption (e.g. bus converters) can be directly supplied via the
CAN connector.
When using this option the 5-Volt supply is connected to the power
supply of the computer and is not fused separately. For galvanic
isolation the measuring unit contains an interconnected DC/DC
converter. Therefore the current output is limited to 50 mA.
Proceed as follows to activate the 5-Volt supply:
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the PCAN-cPCI card. Take precautions to avoid
ESD when handling the card.
Set the solder bridge(s) on the PCAN-cPCI card according to the
desired settings. During this procedure take especially care not to
produce unwanted short circuits on the card.
Figure 3 shows the positions of the solder fields on the PCAN-cPCI
card. The table below contains the possible settings.

Attention! Risk of short circuit! If the option described in this
section is activated, you may only connect or disconnect CAN
cables or peripheral systems (e.g. bus converters) to or from
the PCAN-cPCI card while the computer is de-energized.

3.3 Cabling
3.3.1 Termination
A High-speed CAN bus (ISO 11898-2) must be terminated on both
ends with 120 Ohms. Otherwise, there are interfering signal
reflections and the transceivers of the connected CAN nodes (CAN-
interface, control device) will not work.
The PCAN-cPCI card does not have an internal termination. Use the
card on a terminated CAN bus.
3.3.2 Example of a Connection
Figure 4: Simple CAN connection
In this example, the PCAN-cPCI card is connected with a control unit
by a cable that is terminated at both ends.

3.3.3 Maximum Bus Length
High-Speed-CAN networks may have bit rates of up to 1 Mbit/s. The
maximum bus length depends primarily on the bit rate.
The following table shows the maximum possible CAN bus length
at different bit rates:
Bit rate Bus length
1 Mbit/s 40 m
500 kbit/s 110 m
250 kbit/s 240 m
125 kbit/s 500 m
50 kbit/s 1.3 km
20 kbit/s 3.3 km
10 kbit/s 6.6 km
5 kbit/s 13.0 km
The listed values have been calculated on the basis of an idealized
system and can differ from reality.

4.1.2 Trace Tab
Figure 9: Trace Tab
On the Trace tab the data tracer of PCAN-View is used for logging
the communication on a CAN bus. During this process the CAN
messages are cached in the working memory of the PC. Afterwards
they can be saved to a file.
The tracer can be configured to run in linear or in ring buffer mode.
In linear buffer mode the logging is stopped as soon as the buffer is
filled completely. In ring buffer mode the oldest messages are
overwritten by incoming ones.
