5.5 Communication
5.5.1 Communication via PC adapter
For connection to the RS 232 interface of a PC a WIC1PC2 adapter is needed.
For connection to the USB interface of a PC a WIC1-PC3 adapter is needed.
Through these adapters the galvanic isolation between protection device and the PC is reached and it supplies the
WIC1 with the necessary energy. For communication a proprietary Woodward protocol is used.
