CAN Interface

The dual CAN Interfaces use the TJA1040 CAN driver (IC3 for CAN1 and IC4 for CAN2) and termination resistors (R4 and R6 for CAN1 and R13 and R15 for CAN2) on the MCB1700 board. The driver settings may be changed by the configuration jumpers.

MCB1700 Board 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 TJA1040 CAN driver IC.

  • CAN termination resistors make it easy to connect the MCB1700 board to your CAN network but they are not always required. When connecting the MCB1700 Board to a CAN network, you may need to remove the termination resistors.
