The CAN interface uses the TJA1040CAN driver (N3) and termination resistor (R49) on the STR7 board. The driver settings may be changed by the configuration jumpers.
The CAN DB9 connector is wired so that Pin 2 provides the CANL signal and Pin 7 provides the CANH signal. These pins are connected to the TJA1040 CAN driver IC.
Note
- CAN termination resistors make it easy to connect the MCBSTR7 board to your CAN network but they are not always required. When connecting the MCBSTR7 Board to a CAN network, you may not want the termination resistor R49 attached to the bus. Remove jumper X30 to disconnect terminating resistor R49 from the CAN bus.
