CAN Interface

The dual CAN Interfaces use the L9615 CAN driver (N3 for CAN1 and N4 for CAN2) and termination resistors (R26 for CAN1 and R27 for CAN2) on the MCBSTR730 board. The driver settings may be changed by the configuration jumpers.

MCBSTR730 Board with CAN

The CAN1 and CAN2 DB9 connectors are wired identically (Pin 2 provides the CANL signal and Pin 7 provides the CANH signal) and each is connected to a L9615 CAN driver IC.

Note

  • CAN termination resistors make it easy to connect the MCBSTR730 board to your CAN network but they are not always required.  When connecting the MCBSTR730 Board to a CAN network, you may not want a termination resistor attached to the bus.
  • Remove the configuration jumper (X2 for CAN 1 and X3 for CAN2) to disconnect the terminating resistor (R26 and R27, respectively) from the CAN bus.
