1 Introduction
The PCAN-PCI/104-Express card enables the connection of one, two,
or four CAN buses to a PCI/104-Express system. Up to four cards
can be stacked together. The CAN bus is connected using a 9-pin D-
Sub plug on the slot bracket supplied. There is a galvanic isolation
of up to 500 Volts between the computer and the CAN sides. There
are versions with one, two and four channels.
The monitor software PCAN-View and the programming interface
PCAN-Basic for the development of applications with CAN
connection are included in the scope of supply.
Device drivers exist for different operating systems, so programs
can easily access a connected CAN bus.
Tip: At the end of this manual (Appendix C) you can find a
Quick Reference with brief information about the installation
and operation of the PCAN-PCI/104-Express card.

PC/104 stack.
Install the driver before you insert the card into the stack.
Do the following to install the driver:
1. Start Intro.exe from the supplied DVD.
The navigation program starts.
2. Select in the main menu Drivers and click on Install now.
3. Confirm the message of the User Account Control related to
"Installer database of PEAK Drivers".
The driver setup starts.
4. Follow the program instructions.

Do the following to insert the card into the stack:
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the card. Take precautions to avoid ESD.
1. Shutdown the computer.
2. Disconnect the computer’s power supply.
3. Insert the card into the stack next to the host or to another
PCI/104-Express card.
A maximum of 4 PCI/104-Express cards per stack is possible,
either all on top or all beneath the host.
4. Plug a cable from the slot bracket to a 10-pin socket for each
CAN connection.
5. Reconnect the power supply of the system.
6. Turn on the computer and start Windows.
Windows detects the new hardware and completes the driver
installation.
Do the following to check the operational readiness:
1. Open the Windows Start menu.
2. Type peakcpl and press Enter .
The information window for PEAK hardware appears. The plug-in
card must be displayed in the table on the CAN Hardware tab.

3 Connecting the CAN Bus
3.1 Connection over 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® 303-1.
Figure 1: Pin assignment High-speed CAN
Low power devices (e.g. bus converters) can be supplied directly
with 5 volts over pin 9 of the CAN connector. Pin 9 is not in use at
the delivery state. For more information see the next section 3.2.
The pin assignment between the D-Sub port and the 10-pin
connector on the PCAN-PCI/104-Express card is as follows:

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).
3.1.1 Slot Bracket with D-Sub Connectors
Figure 3: Single channel slot bracket Figure 4: Dual channel slot bracket
To connect a CAN bus to the PCAN-PCI/104-Express card, use the
supplied slot brackets. After you have connected the cables from
the slot bracket with the 10-pin sockets, you can connect the CAN
buses with the D-Sub sockets.

3.2 Voltage Supply of External Devices
External devices with low power consumption (e.g. bus converters)
can be directly supplied via the CAN connector (independently for
each connector on the Dual- and Four Channel models). With a
solder bridge per CAN channel on the PCAN-PC/104-Express board,
a 5-Volt supply can optionally be routed to pin 9 of the D-Sub
connector. The current output is limited to 50 mA.
Do the following to activate the voltage supply:
Risk of short circuit! Solder with great care to avoid unwanted
short circuits on the card.
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the card. Take precautions to avoid ESD.
Set the solder bridge(s) on the card according to the desired
settings.
Figure 5 shows the solder field positions on the card. The table
below contains the possible settings.
Note: The pin labels for the CAN connector are related to the
9-pin D-Sub connector being connected via a cable to a socket
on the card.

3.3 Cabling
3.3.1 Termination
A High-speed CAN bus (ISO 11898-2) must be terminated with 120
ohms at both ends. The termination prevents interfering signal
reflections and ensures the proper operation of the transceivers of
the connected CAN nodes (CAN interfaces, control devices).
The PCAN-PCI/104-Express card does not have an internal
termination. Use the adapter on a terminated CAN bus.
3.3.2 Example of a Connection
Figure 6: Simple CAN connection
This example shows a connection between the PCAN-PC/104-
Express card and a control unit. The connection cable is terminated
with 120 ohms at both ends.

PCAN-PCI/104-Express – User Manual

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 Software and API
This chapter covers the provided software PCAN-View and the
programming interface PCAN-Basic.
4.1 Monitor Software PCAN-View
PCAN-View is simple Windows software for viewing, transmitting,
and logging CAN and CAN FD messages.
Note: This chapter describes the use of PCAN-View with a CAN
adapter.
Figure 7: PCAN-View for Windows

PCAN-PCI/104-Express – User Manual

Do the following to start and initialize PCAN-View:
1. Open the Windows Start menu and select PCAN-View.
The Connect dialog box appears.
Figure 8: Selection of the hardware and parameters
2. Select an interface from the list.
3. From the drop-down list, select the Bit rate that is used by
all nodes on the CAN bus.
Tip: You can create custom bit rates by using the button ().
4. Under Filter settings you can limit the range of CAN IDs to
be received, either for standard frames (11-bit IDs) or for
extended frames (29-bit IDs).
5. Activate the Listen-only mode if you do not actively
participate in the CAN traffic and just want to observe. This
also avoids an unintended disruption of an unknown CAN
environment (e.g. due to different bit rates).
6. Confirm the settings in the dialog box with OK. The main
window of PCAN-View appears (see Figure 9).

4.1.1 Receive/Transmit Tab
Figure 9: Receive/Transmit tab
The Receive/Transmit tab is the main element of PCAN-View. It
contains two lists, one for received messages and one for the
transmit messages. The CAN data format is hexadecimal by default.
Do the following to transmit a CAN message with PCAN-View:
1. Select the menu command Transmit > New Message
(alternatively or Ins ).
The New Transmit Message dialog box appears.
Figure 10: Dialog box new transmit message

PCAN-PCI/104-Express – User Manual

2. Enter the ID, the data Length, and the CAN message Data.
Note: With the program version 4 of PCAN-View, the DLC field
was renamed to Length. Latter reflects the actual data length.
3. Enter a value into the Cycle Time field to choose manually
or periodically message transmission. Enter a value greater
than 0 to transmit periodically. Enter the value 0 to transmit
only manually.
4. Confirm the entries with OK.
The created transmit message appears on the
Receive/Transmit tab.
5. You trigger selected transmit messages manually with the
menu command Transmit > Send (alternatively Space bar).
The manual transmission for CAN messages being
transmitted periodically is carried out additionally.
Tip: Using the menu command File > Save the current transmit
messages can be saved to a list and loaded for reuse later on.

4.1.2 Trace Tab
Figure 11: Trace tab
On the Trace tab, the data tracer (data logger) of PCAN-View is used
for logging the communication on a CAN bus. During this process
the messages are cached in the working memory of the PC.
Afterwards they can be saved to a file.
The Tracer runs either in linear or in ring buffer mode. The linear
buffer mode stops the Tracer as soon as the buffer is full. The ring
buffer mode overwrites the oldest messages by new ones as soon
as the buffer is full.
