Handheld CAN network diagnostics unit

PCAN-Diag 2 is a handheld diagnostics unit with a wide range of functions to allow investigation of a CAN network, such as detection of the CAN bit-rate, bus load measurement, and termination measurement. As well as receiving CAN messages, it can transmit either individual messages or entire sequences of them.

The integrated two-channel oscilloscope enables visualization of CAN signals. Single CAN-IDs and various events can be used as triggers. The CAN frames are decoded from the analog signal, for example, to detect errors in the frame.

Incoming CAN messages can be displayed as symbols for clear and easy allocation. The PCAN symbol editor software supplied with this product enables convenient creation of the symbol files needed for this feature.

Output is through a color display with OLED technology which allows excellent readability even when there is strong ambient light. The user selects and operates the individual diagnostic functions using a push dial. As an alternative to high-speed CAN, CAN transceiver modules are also available on request for connecting to low-speed or single-wire CAN.

Specifications

• High-speed CAN (ISO 11898-2), CAN transceiver module available on request for low-speed CAN (ISO 11898-3) or single-wire CAN (SAE J2411)
• CAN connection is DE-9
• Select from fixed and 8 user-defined bit-rates
• OLED display with 320 × 240 pixel resolution
• Power supply via batteries (4 × 1,5 V AA) or using supply unit provided (low-voltage socket on unit)
• Management of device configuration, transmit lists, symbol files, and all recorded data (screenshots and CSV files) in projects
• Internal memory card (min. 1 GiB) for saving projects. Can also be used as a USB mass storage device when connected to a PC

Overview of functions

• Symbolic display of incoming CAN messages using symbol files, taking enums (lists of values) and multiplexers into account
• Symbol files can be set up using the PCAN symbol editor software supplied with this product
• Transmitting individual CAN frames or CAN frame lists
• Measurement of CAN network load, displayed by means of time diagrams
• Bus-load time diagrams can be saved as bitmap screenshots
• Measurement of CAN termination for high-speed CAN, even while the system is running
• Switchable CAN termination for the connected bus, depending on the transceiver module used
• Voltage measurement for all pins of the CAN connector (D-Sub)
