Terrestrial band Satellite band
- Preamplifiers power -
The power for terrestrial band are : OFF , 5V , 13V , 18V and 24V .
If, contrarily, the satellite band has been selected, the installer can select the power and the
tone of the LNB, and the following sub-menu will appear.
At the bottom of the previous window, the band (high or low) and the polarization (vertical or
horizontal) corresponding to the power and tone selected are indicated:
It should be noted that when a voltage is enabled to power an external device, the only red LED
that the equipment possesses turns on . If this LED blinks, it is a sign of a
problem .
One should also bear in mind that voltage programming is associated with the band chosen for
the equipment, so if one chooses 24V in terrestrial, this will not imply that the same voltage will
be used for satellite.
The equipment continually monitors the voltage through the 'F' connector, and warns of any
anomaly using a message window that is overprinted on any other open window.
The possible problems that may appear in relation to external unit power are the following:
OFF
5V / 100mA
13V / 400mA
low band – vertical polarization
18V / 300mA low band – horizontal polarization
24V / 75mA pre-amplifier power
13V 22KHz / 400mA high band – vertical polarization
18V 22KHz / 300mA high band – horizontal polarization
Auto
The channel table selected automatically inserts the suitable
voltage and tone (
considering a universal LNB ) to select the ( high
or low ) band and the ( vertical or horizontal ) polarization to tune in
on the respective channel.
