The DCSS is an extension of the DiSEqC protocol that allows the connection of several receptors on
only one
coaxial cable
, no matter the band (H/L) and the polarization (H/V).
Functioning:
Each satellite receptor uses a fix frequency band (
Slot
or
Port
), whose width is (more or less) equal to the
width of the transponder.
The receptor requires a specific transponder frequency (frequency Ku) via a DiSEqC command.
Some equipment on the satellite dish (LNB or switch) moves the requested signal to the center of the selected
band (
Slot
). Then, the mixing equipment adds each user band (
Slot
) to only one output (up to 32 user bands).
2 Modes :
SATCR
: Satellite Channel Router, standard EN50494 (or SCD, Unicable, …)
Distribution of the satellite signal with only one coaxial cable to 2, 4 or 8 different receptors.
SCD2
: Single Cable Distribution v2, standard EN50607 (or SCD2, Unicable II, JESS)
Distribution of the satellite signal with only one coaxial cable to a maximum of 32 different receptors.
Using DiSEqC 2.0 bi-directional possibility to ask current online devices and speed up installation.
Mode choice:
press DCSS
The DCSS mode has priority on all other modes: selection polarization, selection
OL, switches committed and uncommitted and positionner.
