a. Input Menu

The fi 

rst standard menu allows selection of 

input frecuencia/input channel

, input signal 

bandwidth

 and 

powering for preamplifi ers 

.

INPUT

Freq:666.000

Bw:     8MHz

Preamp:  12V

INPUT

Ch:C45

Bw:     8MHz

Preamp:  00V

To make a change press the key   until the desired
parameter fl ashes. Then, this fi eld can be changed
by means of the keys   and  .

You can select any frequency value between 46 a 
862 MHz.
The decimal part depends on the frequency step
selected (see extended menu b ). If the frequency
step is defi ned as 125KHz, decimal part values
allowed are: 0, 125, 250, 375, 500, 625, 750 and 875
KHz. If it is a 166 KHz step, then the values allowed
are: 0, 166, 333, 500, 666 and 833 KHz.

Possible COFDM bandwidths are: 7MHz or 8MHz. 

Available voltages to power premaplifi ers are: 0, 12 
and 24 Vdc.

Insert the programmer in the front connector of
the module (“PRGM”). First, the programmer’s

b. QAM modulation menu

The following standard menu displays the 
selectable 

QAM modulation parameters

:

QAM

Mod:  256QAM

IQ:   normal

Baud:6.900Mb

The available options for this menu and their 
possible values are:
-  

QAM modulation

 order: 16QAM, 32QAM, 

64QAM, 128QAM y 256QAM.

-  The 

IQ

 parameter is the modulation format 

selection and can be set to “normal” or “inversion”. 

-   In the processing mode (see Confi guration menu 

2) the user must select the baud rate of the QAM 
output, up to a maximum of 6.9 Mbaud.

    In transparent mode, this parameter is calculated 

automatically as a function of both input rate and 
modulation order you have selected, and can not 
be changed. If the selected QAM modulation is 
not able to make room to the input rate, it will 
show “OVF!” (Overfl ow) and the value of the QAM 
output rate. If the satellite input is not engaged, it 
will show “Baud: unlock”.
