Connecting the Fieldbus
►If necessary install bus termination (see CAN Bus Termination, p. 18).
►Observe the pin allocation.
►Connect the CAN fieldbus connector to the CAN fieldbus.
►Start canAnalyser on the computer.
►In canAnalyser adjust the USB-to-CANFD properties according to fieldbus
characteristics:
Devices which only support CAN 2.0 (CAN high-speed) destroy CAN FD
telegrams!
Only use CAN FD format in networks purely using CAN FD devices or with
CAN 2.0 devices unplugged or switched to standby.
– To activate CAN FD, activate the checkbox Use CAN FD format.
– To use ISO CAN FD frames, activate the checkbox Use ISO conform
frame.
– To use non-ISO CAN FD frames, deactivate the checkbox Use ISO
conform frame.
ISO CAN FD frames and non-ISO CAN FD frames are incompatible!
Use either ISO CAN FD or non-ISO CAN FD in the fieldbus network.
USB-to-CANFD User Manual 4.01.0350.20000 1.6 en-US

Installation 15 (26)
– Select predefined CAN FD bitrate in drop-down list Bitrate.
With a predefined CAN FD bitrate the CAN FD standard bit timing and the CAN
FD fast bit timing are specified and bit rate switching is enabled.
►Define the CAN messages to be transmitted in the transmit window of the
canAnalyser.
►To transmit CAN messages with flexible data rate, activate the boxes FDF
and Fast.
►Start canAnalyser communication.
→ Received CAN messages are shown in the receive window of the
canAnalyser.
→ CAN LED is green flashing with each CAN message.
5.2.3 Connecting the LIN Fieldbus
LIN functionality is only available on USB-to-CANFD automotive variant and USB-
to-CANFD PCIe Mini variant with LIN interface.
Power consumption is limited by a 1 kΩ resistor.
The LIN interface can receive and transmit LIN frames according to LIN
specification V1.3 and V2.0/2.1. The LIN interface can be configured as LIN
master.
A 1 kΩ pull-up resistor is automatically activated in LIN Master mode and
automatically deactivated in LIN Slave mode. External pull-up resistors are not
necessary.
►To use the LIN interface connect a voltage of 12 V DC (voltage range see
Technical Data, p. 19) to pin VBATLIN (see Pin Allocation , p. 13 or Pin
Allocation PCIe Mini LIN Interface 3, p. 14).
To ensure successful transmission of LIN messages:
►Connect the external voltage before LIN messages are transmitted.
►Make sure, that the external voltage is not switched off and on during
operating in LIN mode.
