Picture 5 shows internal structure of satellite inputs. Each SAT port has individual settings, where a power
supply can be switched on/off, LNB Lo/Hi frequency or DiSEqC parameters set up:
V, Lo: 0 V or +13 V;
H, Lo: 0 V or +18 V, see picture 6.
V, Hi: 0 V or +13 V 22 kHz. This port supports DiSEqC as well, see picture 7.
H, Hi: 0 V or +18 V 22 kHz. This port supports DiSEqC as well;
Aux In1: 0 V or +13 V. When Aux In1 LNB power is set to „RF V,Hi“, this port is disabled, see pictures 5, 8.
Aux In2: 0 V or +18 V. When Aux In2 LNB power is set to „RF H,Hi“, this port is disabled.

RF signal from Aux In1 and Aux In2 ports can be connected to 9-16th demodulators only or be disabled.
When Aux In1 LNB power is set to 0V or +13V, switch S1 connects Aux In1 port to 9-16th demodulators and
connects DC 0V or +13V for LNB. When Aux In1 LNB power is set to „RF V,Hi“, switch S1 connects 9-16th
demodulators from port Aux In1 to port V,Hi, disconnecting DC from this port, see picture 5.
Summary output current for LNB from ports V,Lo, V,Hi, H,Lo, H,Hi is shown in Specications independing
from Aux In1, Aux In2 settings.
Summary output current for LNB from ports Aux In1, Aux In2 is shown in Specications independing from
another ports settings.
8.3 RF inputs
16 demodulators can be set up in this section. See picture 9. „SAT input“ parameter can switch demodulator off
or connect to any available RF input. Demodulators 1-8th can connect only to V,Lo/H,Lo/V,Hi/H,Hi inputs.
Depending on „Aux In/LNB Power“ parameter of „LNB Settings“ section, in case of „SAT input“ 3rd and 4th
selection, demodulators 9-16th will be connected either to V,Hi/ H,Hi or to Aux In1/2 ports.
„Input frequency“ parameter is a frequency of transponder in MHz. Ensure, that SAT IF frequency
(FRtransponder - LNB Lo/Hi) ts into demodulator’s input frequency range.
In case of DiSEqC, device will try (if possible) to automatically select Lo or Hi frequency to t into the IF
frequency range.
„Symbol rate“ parameter is a symbol rate of transponder in kSym/s.
„Modulation standard“ allows to select modulation type of DVB-S or DVB-S2.
Press „Update“ button to set new parameters.
There are various status parameters of input signal right to the „Update“ button. „Lock status“ can have
following values:
