The 8PSK-QAM transcoder allocates the
information contained in a satellite
transponder no matter the modulation used
(QPSK legacy, Turbo QPSK or 8PSK) in a
cable channel in VHF or UHF with its typical
channelization (maximum 8.3 MHz). The
channelisation depends on the useful bitrate
of the satellite transponder and the format of
the QAM modulation used.
To accomplish this function, prior to all the
8PSK-QAM carries out the demodulation of
the input channel (satellite transponder),
obtaining the MPEG2 transport stream, to
further modulate it in QAM format, which
implies a digital information modulation
change (digital transmodulation).
The parameters of input channel and output
channel are selected by means of the
programmer ref. 7234 which is attached to
the device front pannel(s). It is also possible
to program the unit by means of a PC, as it
is explained in paragraph 7.
The 8PSK-QAM has two satellite "F-
connectors". The upper connector (1) is the
input signal connector and also it enables
the satellite LNB power up. The lower
connector (2) loops the input signal to the
adjacent 8PSK-QAM device.
In case of power up short circuit, the frontal
LED blinks, halting the blinking when the
shortcircuit ceases, restoring the LNB
power up voltage.
The 8PSK-QAM has also two channel RF
connector, being the lower (4) the output RF
and the upper (3) the RF input which allows
the channel mixing for the further
amplification stage.

It is provided with two input signal connectors, to allow the mixing of
the signals of two systems. If only one input is used, it is
recommended to load the unused input with a 75ohm load (ref. 4061).
It has an output connector and a test output (-30 dB) placed in the
upper part of the front pannel.
15 volts is used for power up, by means of a cord similar to the one
used to power up the rest of the system elements.
Broadband amplifiers in shielded zamak chassis, with gain

a.- Input menu
The first main menu shows the 8PSK-QAM
input frequency and symbol rate (baud rate),
as well as the LNB power selection.
The input frequency range is 950-2150 MHz,
and the symbol rate is 10.000 to 30.000
Kbaud.
The power options for the LNB are 0V, 13v
22 KHz, 13v, 17v 22KHZ and 17 v.
To change the frequency or symbol rate,
press the key until the cursor is over the
selected digit. Change using the and
keys.
To change the selection of the LNB power,
press the key until the required parameter
flashes. Change using the and keys.

selected in section 5.2.a, as it will be
selected automatically according to the
automatic connection table.
Otherwise (in normal mode), 16, 32, 64, 128
or 256QAM may be selected. It is important
to bear in mind that the maximum symbol
rate in QAM is 7.2 Mbaud.
For example:
Input symbol rate: 27.5 Mbaud
Input Viterbi code: 3/4
Selec. Modulation Format: 32QAM
Symbol rate in 32QAM=
(27.5 x 2 x 3/4)/5= 8.25 Mbaud
This symbol rate is higher than the
maximum of 7.2 Mbaud, meaning that a
higher modulation format must be chosen:
64QAM or 128QAM. For example, if we
select 64QAM, the symbol rate for the
previous values will be 6.875 Mbaud, and
5.893 Mbaud for 128QAM.
The next parameter, spectrum inversion (IQ),
makes it possible to change the IQ
modulation format to normal or inverted.
Output level with range from 00 to 99.
To change the QAM modulation order,
spectrum inversion and output level, press
the key until the required parameter
flashes. Change using the and keys.
c.- Measurement menu
This menu shows the following information:
Carrier/Input Signal Noise Ratio, which
indicates the quality of the input signal.
To guarantee correct functioning, we
recommend leaving the unit configured with
a minimum C/N of 11dB.
MONITO
C/N: 12.4dB
QAM: 6.875Mb
Temp.:42.0ºC
The next parameter shows the QAM symbol
rate of the output signal. This figure is useful
when programming some IRDs.
If the QAM modulator is not connected, the
message “QAM: unlock” will be shown.
Internal Temperature shows the temperature
inside the 8PSK module in Centigrade.
As it is a read-only menu, neither nor
and keys are operative.

5.2.- EXTENDED MENU
Holding down the key for more than 3
seconds will bring up a series of menus for
less frequent use, called extended menus.
a.- Configuration menu
Holding down the key gives access to the
different configurations of the unit, which are
changed using the and keys. These
configurations are the following:
Functioning mode: QPSK Scan,
Autoconfig, 8-PSK (2/3, 3/4, 4/5, 5/6, 8/9)
and TurboQPSK (1/2, 2/3, 3/4, 5/6, 7/8). In
the 8-PSK and TurboQPSK functioning
mode, the user select the configuration
parameters, as specified up to now. In the
Autoconfig mode, the unit finds the symbol
rate and QAM modulation format from a
search table with priority as shown below:
CONFIG

Output:CW
CDCAddr: 001

Output:Norm
CDCAddr: 001

User manual 8PSK-QAM
When the working mode "Auto config" is
selected, the menus Input and QAM will be
modified. The selection of the Symbol Rate
and the QAM Modulation format will not be
available any more.
Output: Norm, CW, OFF . Norm turns on
the modulated signal output in QAM, while
CW provides a continuous carrier at the
same frequency as the output signal. Finally,
OFF turns off the QAM modulator, meaning
that there is no output signal.
Finally, the CDCAddr menu allows users to
change the device address in the main
Televés control system. The range of
permitted addresses is from 1 to 254.

6.- ACCES CODE
The 8PSK-QAM allows a 4-digit access
code to be used optionally, using values
outside of the input frequency range (0000-
0949 and 2151-9999), thereby allowing for
8799 different access codes.
The access code for the 8PSK-QAM
operates as follows:
- To enter an access code, an input channel
must be saved in the range of unused
frequencies. Pressing the key for
approximately 3 seconds will bring up the
following screen:
- To check the password, the key must
be held down for approximately 3
seconds. The screen will show the
following message:
The paswword
will be set
to:
2930
- From this moment a key symbol will be
shown in the upper right-hand side of the
screen, indicating that the unit is blocked:
- If any attempt is made to change a
parameter, the user will be asked to enter
the password in the following screen:
The user must enter the correct password
and save it (by pressing the key for
approximately 3 seconds). The unit will then
unlock, and the key symbol will disappear
from the upper right-hand side of the
screen.

5.4.- STATUS LEDS
Finally, the LEDS of the programmer show
working conditions of the device:
Insufficient input signal/noise ratio
QPSK modulator unlocking
QAM modulator unlocking
QAM modulator locking
Finally, the front LED incorporates a direct
view of the status of the device, showing a
quick blinking in case of an unlock condition
of the QPSK demodulator or QAM
modulator, which blinking dissapears when
the lock condition is restored.

7.- CONTROLLING THE DEVICE
This version of the 8PSK-QAM permits
configuration and control from a PC, both
locally and via remote control.
a.- Local control
The user must have the "Headend
Management" program version 2.12 or
upper and a special cable (provided with
this program) that connects a PC serial port
to the "PRGM" connector of the 8PSK-
QAM.
Using the program, the user can configure
and read all of the parameters, as well as
check that the device is working properly.
b.- Remote control
As well as the program previously
mentioned, it is necessary to have a
Headend Control module (ref. 5051 or 5052)
and the corresponding modem connected
to the telephone line. Once communication
has been established with the headend
control, you will be able to access all the
controllable devices that have been installed
in the headend.
In this case, it is essential that every element
is programmed using a different device
address (address RS485) between 1 and
254.

To mount the units in the rack with
ventilation, you must mount blank plates ref.
5073 between the modules to allow the
correct ventilation of the equipment, fig. 4.
of the Rack. The air will enter again through
the lower part of the device, fig 3.
9.1.- Installation of the rack with
ventilation facilities.
To facilitate the renewal and circulation of
the air inside the rack, and the temperature
of the units and thus improve their
characteristics, it is advisable to place 2
ventilation units of 25W, particularly when
the rack with the 8PSK-QAM is located in
warm place, with a temperature higher than
40°C.
These ventilators will be placed on a tray,
that is screwed onto the top part of the
Rack, fig. 1 and 2, and in this way the
ventilators will be able to extract the air from
the 8PSK-QAM and will be able to expel it
via the gap (approx. 3-5 cm) at the top part
