Connecting 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 of High-speed CAN connection

(view onto a male connector on the PCAN-PCI 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 delivery 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).

PCAN-PCI – User Manual

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 by setting solder bridges on the PCAN-PCI card

(independently for each connector on the Dual Channel versions).

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. The optodecoupled versions of the card contain an interconnected DC/DC converter. Therefore the current output is limited to about 50 mA.

Proceed as follows to activate the 5-Volt supply:

Attention! Electrostatic discharge (ESD) can damage or destroy components on the PCAN-PCI card. Take precautions to avoid

ESD when handling the card.

Set the solder bridge(s) on the PCAN-PCI 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-PCI

card. The table below contains the possible settings.

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 (CANinterface, control device) will not work.

The PCAN-PCI 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-PCI card is connected with a control unit by a cable that is terminated at both ends.

21

PCAN-PCI – User Manual

4.2.2

Principle Description of the API

The PCAN-Basic API is the interface between the user application and device driver. In Windows operating systems this is a DLL

(Dynamic Link Library).

The sequence of accessing the CAN interface is divided into three phases:

1. Initialization

2. Interaction

3. Completion

Initialization

A CAN channel must be initialized before using it. This is done by the simple call of the function

CAN_Initialize

. Depending on the type of the CAN hardware, up to eight CAN channels can be opened at the same time. After a successful initialization the CAN channel is ready for communication with the CAN hardware and the CAN bus.

No further configuration steps are required.

Interaction

For receiving and transmitting CAN messages the functions

CAN_Read and

CAN_Write

are available. Additional settings can be made, e.g. setting up message filters to confine to specific CAN IDs or setting the CAN controller to listen-only mode.

When receiving CAN messages, events are used for an automatic notification of an application (client). This offers the following advantages:

The application no longer needs to check for received messages periodically (no polling).

The response time at reception is reduced.

22

PCAN-PCI – User Manual

Completion

To end the communication the function

CAN_Uninitialize

is called in order to release the reserved resources for the CAN channel, among others. In addition the CAN channel is marked as "Free" and is available to other applications.

4.2.3
