PCAN-USB – User Manual 1 Introduction The PCAN-USB adapter enables simple connection to CAN networks. Its compact plastic casing makes it suitable for mobile applications. The opto-decoupled version guarantees galvanic isolation of up to 500 Volts between the PC and the CAN side. The package is also supplied with the CAN monitor PCAN-View for Windows and the programming interface PCAN-Basic. Device drivers exist for different operating systems, so programs can easily access a connected CAN bus.
PCAN-USB – User Manual Galvanic isolation on the CAN connection up to 500 V (only PCAN-USB opto-decoupled) 5-Volts supply to the CAN connection can be connected through a solder jumper, e.g. for external bus converter Voltage supply via USB Extended operating temperature range from -40 to 85 °C (-40 to 185 °F) Note: This manual describes the use of PCAN-USB adapter with Windows.

PCAN-USB – User Manual 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 for CAN corresponds to the specification CiA® 303-1. Figure 1: Pin assignment High-speed CAN (view onto connector of the PCAN-USB adapter) Low power devices (e.g. bus converters) can be supplied directly with 5 volts over pin 1 and pin 9 of the CAN connector. Pin 1 and pin 9 is not in use at the delivery state.
PCAN-USB – User Manual 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. With a solder bridge for the one CAN channel on the PCAN-USB board (casing opened), a 5-Volt supply can optionally be routed to pin 1 and/or pin 9 of the D-Sub connector (for PCAN-USB opto-decoupled to S/N 199999 only pin 1 available). The opto-decoupled model of the adapter contains an interconnected DC/DC converter.
PCAN-USB – User Manual 4. Place the board overhead onto the top part of the casing. The cable must lie with the strain relief in the cut-out of the casing and the LED must be in the corresponding hole. 5. Push the bottom part of the casing onto the top part until the latches click in.

PCAN-USB – User Manual 3.3 Activating the Internal Termination Only applicable to adapters from S/N 200000. The internal termination can be activated by solder jumpers on the circuit board to terminate one end of the CAN bus. At delivery the termination is not activated. A High-speed CAN bus (ISO 11898-2) must be terminated on both ends with 120 Ohms. Otherwise disturbances may arise.

PCAN-USB – User Manual 3.4 3.4.1 Cabling Termination The High-speed CAN bus (ISO 11898-2) must be terminated with 120 ohms on 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-USB adapter to S/N 199999 does not have an internal termination. From S/N 200000 it has an optional internal termination with 120 Ohms. See the previous section 3.
PCAN-USB – User Manual 3.4.3 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.

PCAN-USB – User Manual 5.1.1 Receive/Transmit Tab Figure 11: 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.
PCAN-USB – 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.
PCAN-USB – User Manual 5.1.2 Trace Tab Figure 13: 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.
PCAN-USB – User Manual 5.1.3 PCAN-USB Tab Figure 14: PCAN-USB tab The PCAN-USB tab contains some detailed information about the hardware and driver. In addition, you can assign a device ID to the adapter. Thus, it can be uniquely identified while operating several PCAN-USB adapters on a computer at the same time. To identify a PCAN-USB adapter, you first go to the dialog box for selecting the hardware of PCAN-View (Figure 10 on page 19).
PCAN-USB – User Manual 5.1.4 Status Bar Figure 15: Display of the status bar The status bar shows information about the current CAN connection, about error counters (Overruns, QXmtFull) and shows error messages. You can find further information about the use of PCAN-View in the help which you can invoke in the program via the Help menu or with the F1 key.
PCAN-USB – User Manual 5.2 Linking Own Programs with PCAN-Basic Figure 16: PCAN-Basic On the provided DVD, you can find files of the PCAN-Basic programming interface in the directory branch Develop. This API provides basic functions for linking own programs to CAN and CAN FD interfaces by PEAK-System and can be used for the following operating systems: Windows 10, 8.1, 7 (32/64-bit) Windows CE 6.x (x86/ARMv4) Linux (32/64-bit) The API is designed for cross-platform use.
PCAN-USB – User Manual Beginning with version 4, PCAN-Basic supports the new CAN FD standard (CAN with Flexible Data Rate) which is primarily characterized by higher bandwidth for data transfer. 5.2.1 Features of PCAN-Basic API for developing applications with CAN and CAN FD connection Access to the CAN channels of a PCAN-Gateway via the new PCAN-LAN device type Supports the operating systems Windows 10, 8.1, 7 (32/64-bit), Windows CE 6.
PCAN-USB – User Manual Output language depends on operating systems Debugging information can be defined individually Thread-safe API Tip: An overview of the API functions is located in the header files. You can find detailed information about the PCAN-Basic API on the provided DVD in the text and help files (file name extensions .txt and .chm). 5.2.2 Principle Description of the API The PCAN-Basic API is the interface between the user application and device driver.
PCAN-USB – User Manual confine to specific CAN IDs or setting the CAN controller to listenonly 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.
