With DiSEqC, the switching signals are transferred in series as encrypted digital words. Standard in computer technology, eight bits make one byte (increasing order), followed by one parity bit (odd). The DiSEqC data word contains a frame byte, an address byte and a command byte, which can be followed by a data byte.

[Frame] [P] [Address] [P] [Command] [P] (Data) P
