6.4. Adapter interface specifications
The pin outs of the adapter interface connectors mounted on the user system are shown in Tables 3.
The recommended connectors are listed in Table 4, and the pin configuration is shown in Figure
6.4.1.
When the adapter interface connector is mounted on the user system, connect the MCU to the
adapter interface connector according to the following specifications.
