Slave components are all DiSEqC components e.g. LNBs, relays and multiswitches. Components, which are unfortunately named "DiSEqC compatible", can analyse only the ToneBurst, not however real DiSEqC commands.
- DiSEqC 1.0 components react to the committed DiSEqC commands (Band, Polarisation, Position, Option), however the Slave cannot send a reply to the receiver.
- DiSEqC 1.1 components react to the uncommitted switches, which are four additional control signals so that up to 256 IF signals can be controlled.
- DiSEqC 1.2 components can control steerable dishes.
- DiSEqC 2.0 components react to the DiSEqC commands for the committed switches and can send a reply for acknowledgement. Additionally the configuration bytes of the components can be read out, which enables an automatic receiver installation.
- DiSEqC 2.1 are as 1.1, but reply possible.
- DiSEqC 2.2 are as 1.2, but reply possible.
