PCAN-Diag

2010-07-01 • Handheld CAN Bus Diagnostics Unit


PCAN-Diag is a handheld diagnostics unit with a wide range of functions to allow investigation of a CAN bus, such as detection of the CAN transfer 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 built-in 2-channel oscilloscope allows CAN signals to be displayed. The trigger can be set to frame start or frame end. An explicit trigger frame can also be defined. The CAN frames are decoded based on the analog curve, for example, to detect errors in the frame.

In order to allow clear, simple allocation, the CAN messages can be displayed based on a CAN definition file. Output is through a colour display with OLED technology which allows excellent readability even when there is strong ambient light. The individual diagnostics functions can be selected and operated using a rotating push-button. As an alternative to High-speed CAN, the replaceable CAN transceiver module allows a connection to a Low-speed or Single-wire CAN.
