Hall Sensor Signal Input
The product is equipped with a Hall sensor signal input connector. Using this connector it is possible to input the Hall
sensor signal from the motor supplied with the Motor RSSK directly to the product. The signal input to the product is
pulled up to 5 V and passed through an RC filter before being input to the RX24T. Table 6.6 lists the pin assignments of
the Hall sensor signal input connector, and Table 6.7 lists connector information.
