Since "RDU-A G2" typically refers to the Remote Display Unit (Generation 2) used in industrial automation, generator control, or marine applications (often manufactured by brands like ComAp, Deep Sea, or generic OEMs), I have created a comprehensive generic user manual template.

This content is structured to be technically accurate for standard industrial display units. You can adapt specific pinouts or menu trees to match your specific hardware revision.
