1 Introduction
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 new 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.
Note: This manual refers to devices that are operated from
firmwareversion 1.4.11 and higher.

3.2 D-Sub Voltages
Attention! Do not apply voltages out of the measuring range
from -40 to 43 volts in order to avoid damage to devices and persons.
At the D-Sub Voltages s function, the external voltages at pins 6 (P6) and 9 (P9)
opposite pin 3 (GND) as well as the difference between the two pins (P9-P6) are
displayed. Precondition for the display of the voltage difference is the presence of
voltages at both pins. The measuring range for P6 and P9 is between -40 and 43
volts. The measured value open means that 1.5 volts are applied to the open pin.

3.6.2 Evaluation of the Measurement
A High-speed CAN bus (ISO 11898-2) has to be terminated at both ends with 120 Ω
each between the CAN lines CAN-Low and CAN-High. The two resistors connected in
parallel result in a total resistance of 60 Ω. The following table describes possible
reasons for the respective measurement result:
3 Device Functions PCAN-MiniDiagFD
User Manual 2.0.0 © 2022 PEAK-System Technik GmbH
19

Measurement Result Meaning
~ 60 Ω The termination on the CAN bus is technically ok. Make sure that the
termination resistors are present at the bus ends and not, for example, at the
taps in the middle of the bus.
~ 120 Ω Only one termination resistor is available. Install another 120 ohm resistor.
< 45 Ω Too many termination resistors are present on the CAN bus. This can occur, for
example, if both a separate termination resistor and a CAN node with internal
termination are present at one bus end.
--- Ω The measurement was not successful.
missing No or a too large termination resistor (> 1.2 kΩ) is present on the CAN bus. Set
up a correct termination.
shorted Short circuit (< 10 Ω)! Check whether the PCAN-MiniDiagFD has been properly
connected and terminated.
Jumping value Check whether the PCAN-MiniDiagFD has been connected correctly. For
example, the CAN lines CAN-High and CAN-Low may have been reversed.
Note: A correct termination is important to avoid signal reflections at
the cable ends and to guarantee a correct function of the CAN
transceivers at the CAN bus.
3.7 Bit Rate
With the Bit Rate function, the nominal bit rate, the data bit rate, and the related
sample points are automatically determined by bit timing measurements. The
automatic detection is started with the Enter key . The detection range is from
10 kbit/s to 8 Mbit/s.
