Technology :: DiSEqC :: DiSEqC for Technicians

[6.3] Ordered Co-Existence
Since it is necessary for a transition phase, to continue to transmit conventional switching criteria in addition to DiSEqC commands, the following sequence is recommended. First, the 22kHz tone, if present, is interrupted. After a pause, the DiSEqC information follows, after another pause, the tone burst (SA/SB burst, will be described in 8.1) and after a third pause the 22kHz tone is switched on again if needed. The remote fed voltage can, as depicted, also be switched before or after the tone burst. The pause after the DiSEqC message must last so long that a slave can send its reply to the DiSEqC 2.0 receiver in time before the Tone-Burst.
