Connecting the Serial Communication

The product communicates with the UART via the serial communication connectors. There are three serial
communication connectors: CN2, CN4, and CN6. Table 5.5 lists their pin assignments. Use CN6 when using a tool such
as waveform display in conjunction with the INV-BRD.

Hall Sensor Signal Input

The product is equipped with a Hall sensor signal input connector. The signal input to the product is pulled up to 5 V
and passed through an RC filter before being input to the RX66T. Table 5.6 lists the pin assignments of the Hall sensor
signal input connector, and Table 5.7 lists connector information.
