► In canAnalyser adjust the USB-to-CAN
FD
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.
– 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-CAN
FD
automotive variant and USB-to-CAN
FD
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.
16) to pin VBAT
LIN
(see Pin Allocation , p. 12 or Pin Allocation PCIe Mini LIN Interface 3, p.
12).
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.
