5.1. Normal menu
a. Input menu
The first main menu lets you select the input
frequency, the symbol rate of the input signal
and the power supply of the LNB converter
and it allows the selection of satellite using
DISEqC.

To make a change press the key until the desired
parameter flashes. This field can be then be
changed by means of the keys and .
The range of values allowed for the input frequency
is 950-2150 MHz, whereas for the symbol rate the
range is 2 to 42.5 Mbaud for DVB-S and 10 to 30
Mbaud for DVB-S2.
DiSEqC settings: It allows to select a satellite
from four possible (A, B, C and D) through DiSEqC
commands, for example when the input of the unit
is the output of a multiswitch.
LNB power: The possible values for the power of
the converter are: 0V, 13V, 13V 22KHz tone, 17V,
17V 22KHz tone. The tone is represented with the
symbol “~”.
5. - Instructions for use
Insert the programmer in the front connector of
the module programming (“PRGM”). First, the
programmer’s firmware version will appear:

By pressing + , you access the “cloning”
functions, through which you can copy the
configuration of the transmodulator into the
Remote Control Unit and, in the same way,
download this configuration from the Remote
Control Unit to the transmodulator.
In the remote control unit manual you will find a
decription of the cloning functions.
In case of selecting 0V, the selection of satellite is
disabled while selecting a satellite from 0V it will
change automatically to 13V (is not possible select
DiSEqC with 0V power supply).
In case of a ‘short-circuit’ in the input connector
(power supply enabled for the LNB) the LED on
the front of the module flashes until this condition
disappears.
b. COFDM1 modulation menu
The next main menu allows various COFDM output
modulation parameters to be selected:
COFDM >>
8MHz 64QAM
GI:1/8
FEC:3/4
The parameters that can be selected in this menu
and their possible values are as follows:
• Bandwidth of the COFDM signal: 7MHz or
8MHz.
• Modulation: QPSK, 16QAM or 64QAM.
• Guard interval: 1/4, 1/8, 1/16 or 1/32.
• FEC: 1/2, 2/3, 3/4, 5/6 or 7/8.
