select dummy channel 2 and press the
‘
back’ button to go back to the desired
channel. The antenna will then move to
the correct elevation position already
stored in Motor 2’s memory. When nec-
essary, the elevation position can be
easily adjusted using the remote con-
trol. All you have to do is access the
Motor Configuration menu and use the
fine-tuning tool to bring the signal level
to its highest value.
To make sure this all functions the
way it should, a few tricks are needed.
The two dummy channels used for DiS-
EqC 2/1 switching must correlate with
two different satellites in the receiver’s
satellite list. Since the motors should
be able to drive to every satellite, two
new dummy satellites have to be added
to the list.
For this purpose I loaded the ‘sat-
ellites.xml’ file from the receiver via
FTP. A standard FTP program like the
freeware Filezilla took care of that;
you simply have to configure the new
connection by entering the IP address
of the AZBox ME in the host field. The
user name is ‘root’ and a password
is not needed. Note: if the receiver is
connected to the Internet, you actually
should use a password for the ‘root’ ac-
count. You can connect with Telnet in
the receiver and use the Unix command
‘
passwd’. You will then need to enter a
password twice.
The ‘satellites.xml’ file can be found
in the \etc\tuxbox folder. This file has
to be opened on a PC with an editor
and for this purpose the freeware Note-
pad++ is recommended. It recognizes
the XML structure of the file and pro-
vides it in the corresponding format.
There are two new satellites that
need to be added with the names ‘Mo-
tor 1’ and ‘Motor 2’. I also copied the
lines defining ASTRA 19.2E twice, re-
named them and deleted all but one of
the transponders. The reason for this
is that eventually a scan will be per-
formed on this one transponder.
In order for the AZBox ME to accept
this modified satellite position, the po-
sition has to be altered since the re-
ceiver can only accept one position at
a time. That’s why I changed the en-
try ‘position=192’ to ‘position=193’
and ‘position=194’ so that in the future
I’ll know that these are copies of the
ASTRA 19.2E satellite. Figure 3 shows
these modifications.
This file now has to be copied back to
\
etc\tuxbox using Filezilla. In order for
these modifications to be accepted, the
receiver has to be restarted. Actually,
it would be enough to restart the user
interface, which would be somewhat
faster.
Now it’s time to go to the tuner con-
figuration, that is actually set up for
DiSEqC 1.2 reception on LNB 1, and
switch the two dummy satellites to LNB
2
and LNB 3. LNB 2 is configured in
such a way that it switches to DiSEqC
AA (without any DiSEqC 1.2 control)
and LNB 3 to DiSEqC AB. Now a scan
can be started for both of these satel-
lites whereby the antenna, in my case,
has to be aligned to ASTRA 19.2E.
The scan should only take place on
one transponder since we only need
one channel for each. It should prefer-
ably be an FTA channel in SD resolu-
tion because this would result in faster
channel switching times. See Figure 4.
When this scan is successful, the
Settings list must still be edited. With
the help of your favorite settings editor
for Linux receivers, it’s time to use the
last trick: All of the channels that were
found for both dummy satellites need
to be deleted except for one for each
‘
satellite’.
The remaining two channels are then
renamed to ‘Motor 1’ and ‘Motor 2’ and
Figure 3: In order to control both
motors, the original satellite list is
duplicated twice. In this case the
satellite list 192 (ASTRA 19.2°E) was
resaved twice as satellite list 193 and
again as 194.

satellites were generated through a
