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 corresponds to the
specification CiA® 102.
Figure 2: Pin assignment High-speed CAN
(view onto a D-Sub connector)
With pin 1 devices with low power consumption (e.g. bus conver-
ters) can be directly supplied via the CAN connector. At delivery this
pin is not assigned. You can find a detailed description in the follo-
wing 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 of a D-Sub connec-
tor on the PCAN-miniPCI card (independently for each connector on
the Dual Channel versions). Thus devices with low power consump-
tion (e.g. bus converters) can be directly supplied via the CAN con-
nector. The current consumption may not exceed 50 mA per CAN
connector.
When using this option the 5-Volt supply is connected to the power
supply of the computer. The opto-decoupled versions of the card
contain an interconnected DC/DC converter. In each case resettable
100-mA fuses are interposed.
Important note: The specification for Mini PCI slots provides a
maximum current output of 100 mA on the 5-Volt bar. By the
additional current consumption of external devices this limit
can be exceeded and as a result the correct function of the
computer may be affected.
Proceed as follows to activate the 5-Volt supply:
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the PCAN-miniPCI card. Take precautions to
avoid ESD when handling the card.
Set the solder bridge(s) on the PCAN-miniPCI card according to the
desired settings. During this procedure take especially care not to
produce unwanted short circuits on the card.
Figure 4 shows the positions of the solder fields on the PCAN-
miniPCI 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-miniPCI 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-miniPCI card does not have an internal termination. Use
the card on a terminated CAN bus.
3.3.2 Example of a Connection
Figure 5: Simple CAN connection
In this example, the PCAN-miniPCI 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,
where all CAN nodes must be able to process messages
simultaneously. 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 10: 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.
