■ Adapter interface specifications
The pinouts of the adapter interface connectors mounted on the user system are shown in Tables 3
and 4. The recommended connectors are listed in Table 5, and the pin configuration is shown in Fig-
ure 7.
When the adapter interface connector is mounted on the user system, connect the MCU to the adapter
interface connector according to the following specifications.
