8.1 System interface
The bus module is connected with the relevant system interfaces of the power controllers via X1 to X8
(four-wire, 2x2 twisted, shared shielding).
The transmission rate is 38,400 Bd.
The asynchronous characters are transferred with 8bit, no parity, one stop bit. The protocol begins with
STX, followed by an identifier, the data, and is concluded with a check sum. Defective protocols are
