dCSS/dSCR Multiswitch (Ref. 9733PL & 9734PL) v1.0
7
2.2.
Output: Legacy versus dSCR
Independent of the selected input mode, the outputs can support legacy and SCR/dSCR STBs.
At startup, the unit works in Legacy mode and can be used as a universal multiswitch or
wideband2quad convertor, depending on the position of the switch.
Upon receiving the first dSCR command, the unit will automatically switch into dSCR mode in
which it supports the following standards:
EN50494/SCR standard (DiSEqC 1.0)
STB’s that only support EN50494 will only be able to use the first 8 userbands.
EN50607/dCSS/dSCR standard (DiSEqC 2.0)
STBs that support the newer EN50607 will be able to use all userbands (UB1 – UB25 for
9733PL and UB1 – UB16 for 9734PL). This is typically for new multi-tuner STBs.
CONCURRENT EN50494/EN50607 standards
For upgrading existing SCR installations where the main STB is upgraded to Next Gen PVR, the
dSCR multiswitch can support both standards simultaneously. In this case a mix of STBs can
be supported:
The existing STBs will use UB1 through UB8
The new main STB will use UB1 through UB25 for 9733PL and UB1 through UB16 for
9734PL
In this case DiSEqC 1.0 and DiSEqC 2.0 will be used over the same cable from LNB to
the apartment
For an overview, please see the table in chapter 3: Technical Specifications.
To return back to legacy mode, that output has to be reset. This can be done by removing the
DC from the STB output connector. In case of the 9734PL, the 2 outputs are independent, so
resetting (= unpowering) 1 output does not affect the other output.
