DVB-S2 Input Option Card TT1290/HWO/DVBS2/IF/CONST

The DVB-S2 demod option TT1290/HWO/DVBS2/IF/CONST offers three
L-band inputs plus an IF input. If this input option card is fitted in the receiver then
note that Menu 2.3.5 sets the IF input frequency. LNB Frequency, Satellite
Frequency and LNB Power parameters are not applicable for this input.
The DVB-S2 demod option TT1290/HWO/DVBS2/IF/CONST also offers a
constellation output in DVB-S2 mode. This output can be enabled for each L-
band/IF input from the menu 2.3.X.6. Enabling this mode disables the demodulator
transport stream rendering the receiver unable to decode a service.
