LNB control menu
In the LNB control menu, the LNB supply voltage, 22 kHz control signal, DiSEqC
and VSEC commands can be set. The voltage or signals are available on the RF
socket. If the LNB supply voltage is activated, the red LED above the RF sockets
lights up.
Selection of menu items: refer to section „Operating concept.“
22 kHz control signal
The field lights up
yellow, as soon as the
softkey is pressed. The
switchable 22 kHz
signal superposes the
LNB voltage. By pressing the button once
more, the 22 kHz signal is disconnected
again.
14 V LNB supply voltage
The field lights up yellow, as soon as the
softkey is pressed. The LNB supply
voltage of 14.0 V for the vertical polarisation is now switched on. For control, the
LED above the RF input socket lights up. The voltage can be changed in the
range of 10...20 V with the buttons, 1...9, or with the cursor buttons, ◄►. For nu-
merical entry, the entry must be completed with „Enter.“ By pressing the button
once more, the LNB supply voltage is disconnected again.
18 V LNB supply voltage
The field lights up yellow, as soon as the softkey is pressed. The LNB supply volt-
age of 18.0 V for the horizontal polarisation is available on the input socket. The
voltage can be changed in the ranged of 10...20 V with the buttons, 0...9, or with
the cursor buttons, ◄►. For numerical entry, the entry must be completed with
„Enter.“ By pressing the button once more, the LNB supply voltage is disconnected
again.
The LNB voltage is
- disconnectable= 0V
- changeable from 10…20 V in 0.1-V increments
- short-circuit proof max. current 500 mA
LNB current draw
This field shows the current draw (I = 181 mA) and
the supply voltage (14.6 V) of the LNB.
