The PCAN-MiniDiag FD is a compact, low-cost handheld device for basic diagnosis and checking of CAN and CAN FD buses. Service technicians and developers can easily access networks of vehicles, machines, or industrial equipment whose configuration is unknown. For this, the nominal bit rate for CAN and additionally the data bit rate for CAN FD are determined using bit timing measurement. Furthermore, the device has measuring functions for the termination, bus load, and voltage levels at the CAN connector.
The PCAN-MiniDiag FD has an increased protection due to its membrane keypad and casing. The power is supplied by three replaceable batteries.
The CAN FD standard (CAN with Flexible Data rate) is primarily characterized by higher bandwidth for data transfer. The maximum of 64 data bytes per CAN FD frame (instead of 8 so far) can be transmitted with bit rates up to 10 Mbit/s. CAN FD is downward-compatible to the CAN 2.0 A/B standard, thus CAN FD nodes can be used in existing CAN networks. However, in this case the CAN FD extensions are not applicable.
