5.7 RS232 Serial Port
Serial port SCI2-A is connected to the standard RS232 header fitted to the RSK. Alternatively, serial port SCI1-B or
SCI6-A can be connected to the RS232 transceiver by making changes to the configurations to the jumpers and
option links (refer to §6). Connections between the RS232 header and the microcontroller are listed in the
Table 5-5.

* This connection is a not available in the default RSK+ configuration - refer to §6 for the required modifications.
5.8 Controller-Area Network (CAN)
A CAN transceiver IC is fitted to the RSK+, and is connected to the CAN MCU peripheral. For further details
regarding the CAN protocol and supported modes of operation, please refer to the RX62N hardware manual.
The connections for the CAN microcontroller signals are listed in Table 5-7 below.
