Caution: Please ensure that only one interface is configured for operation at the same
time (either RS232 or LIN) by using DIP switch S10.
4.2.8.2 CAN Interfaces
Controller Area Network (CAN) transceivers (IC1 and IC3) are supplied to provide two CAN bus
interfaces. Each transceiver can be connected to one of the microcontroller’s CAN interfaces
(CAN3, CAN4). The CAN bus interfaces are connected to the DB9 connectors CN1 and CN2.
The CAN0/1 transceiver is enabled by default and able to transmit and receive data via the CANH
and CANL bus lines. The mode can be changed by setting a low level on the NSIL pin and on the
STBY pin selects silent mode via Microcontroller GPIO pin (P1_1 / P2_6). This receive-only mode
can be used to test the connection of the bus medium. In silent mode it can still receive data from
the bus, but the transmitter is disabled and therefore no data can be sent to the CAN bus. DIP
switch S4 provides additional CAN bus interface configuration options including the ability to
selectively interconnect CAN bus interfaces on-board.
The CAN transceiver support CAN and CAN-FD communication.
Please close the following jumpers to connect the CAN0 transceiver (IC1) and CAN1 transceiver
(IC3) to the microcontroller:
