OUTPUT can be used by selecting external power or internal power. When using an external power
supply, the J1's jumper must be disconnected before it is fully isolated.
In case of internal power supply, DC-DC converter power can be selected. When DC-DC converter is used,
J7 jumper setting (3-2 short) is done.
When using external 5V power supply, use J7 jumper setting (1-2 shots).
