LNB Voltage and 22 kHz / 60 Hz Switch-Over

The LNB supply voltage is available at the RF socket. This is confirmed by the LED next to the RF socket which lights up when the voltage supply is switched on. The current consumed by the connected LNB is indicated in the LC display.

The 22 kHz or 60 Hz square wave signal that can be added is superimposed on the LNB voltage. It is needed to switch multifeed systems or high/lowband LNBs.

The LNB voltage can be

∙switched off = 0V

∙set from 10 V to 20 V in steps of 0.1 V

∙short-circuit protected (max. current 500 mA)

The following voltages can be called up by pressing the relevant button:

LNB voltage	Button
0V	[0]
12V	[1]
14V	[2]
18V	[3]

Note

+

[2ndF] [LNB]	Call up the LNB menu
[0]...[3]	Select the LNB voltage
[-] or [+]	Change the LNB voltage in 0.1 V steps
[7]	60 Hz signal on/off
[8]	22 kHz signal on/off

Exit the LNB menu by pressing [2ndF] twice.

Call up the LNB voltage 14 V:

Press buttons [2ndF] [LNB] [2]

LC display:

∙LNB voltage: 14 V

∙Current consumption: 150 mA

By pressing the [+] or [-]buttons you can change the LNB voltage in steps of 0.1 V.

By calling up another function, e.g. [2ndF] [CH-FRQ], you can exit the LNB menu automatically.
