Using the Adacom kit for the first time
The Adacom kit has been already prepaired
with the latest software.It is however necessary to know the frequency and
symbol rate to find your station
on your digital receiver.Stefan writes them mostly on the cover of the Tx since
24-02-2003.You can find them also by opening the Hyperterminal program
(See The Adacom kit,the Online Menu and making your own Testcard).Typing the
letter P will show you all parameters.
All necessary files to install new firmware or configuration file can be
downloaded at the Adacom website http://www.sr-systems.de/de/index.htm.
goto downloads and you will see the following files :
FWTool030206.zip = fwtool.exe.This program
you need to install new firmware and a new configuration file
FWTool_Utils.zip =
cygwin1.dll .This file you also need to install new firmware and a new
configuration file
- dvbs.h
- teletext.c
- teletext.o
- minimal.txt
- minimal.conf
- samplevmtxt.conf
- download.bat
- testpic2.mpg
- vm.exe
- vmas.exe
- vmar.exe
- vmdisass.exe
- vmld.exe
ConfigManual_de.pdf = Manual in German language

The best way to look at your own signal
is via a direct link between the Tx and your receiver by means of a coaxial
cable and a 50-60 db attenuator.
ATENTION : the problem is that all digital receivers I know do have a dc voltage
on the antenna input .To prevent a short-circuit I use a splitter
(see photo),since the dc voltage is blocked by
a diode.
In case that you use a wire as antenne ,the possibility exist that you have
sometimes problems with RF feedback in the shack causing your screen to go
black.
Best way in this case is to use a 3 db attenuator at the Tx output plug.As soon
as you have a picture, live becomes easier.
Now open the receiver Menu and goto the
Installation part.Because all receivers have different menu's it is very
difficult to give instructions.
Therefore I give some examples for several receivers.
HUMAX 5400 (patched) :
Menu--->Installation--->ok--->Service Searching---->password
0,0,0,0--->
SMATV Search : Frequency
-1291
: Symbol Rate - 6000
: FEC
- 3/4 (or automatic)
Normally you can see your signal now in the bottom bar.
--->ok--->now you see the found stations (eg ON4FIN and ON4FIN mux)--->Saving
data etc..--->ok--->exit--->exit.... and there is the picture.
Note: The (no-standard) testcard is normally one channel higher.Due to the fact
that it is a non standard testcard there will show up a red bar saying
(-0602 not available or scrambled).
Using the EPG function shows the testcard without a problem.
Nokia 9800 :
Methode 1 :
Menu--->(6)System adjustments--->ok--->password 1,2,3,4--->ok--->(3)Antenna/Satelite
adjustments--->ok--->(1)One antenna/one LNB configuration
--->ok
LNB
type
: 10000
LNB offset
voltage
: 0 V (the voltage at the Rf input connector will still be there)
Satelite
: Arabsat 2B (this is not necessary,but it will be easier to find the
station back later)
Preprogrammed channel : none
--->ok--->Searching program's--->(2)manual search--->ok--->
Transponder frequency : 11291
(10000+1291=11291
Polarisation
: Horizontal
Symbol Rate
: 6000
FEC
: 3/4
Network Search
: yes
--->ok--->now the search will start--->a window pops up saying ....found
two stations etc..--->ok--->The programs will be saved in memory--->exit.
Look now under Arabsat 2B by pushing the ok button.The no-standard testcard is
one channel higher ,but will not be stable.The screen will blink between
the testcard and black.There are receivers like the Nokia 9500 who show a normal
testcard.
Methode 2 :
Menu--->(6)system adjustments--->password 1,2,3,4--->(3)antenna/satelite
adjustments--->ok--->(1)one antenna/one LNB configuration--->ok
LNB
Type
:IF direct
LNB offset
voltage
: 0 V (the voltage at the RF connector will still be there)
Satelite
: not relevant
Preprogrammed channel : not relevant
--->ok--->(1)Searching program's--->ok--->(2)Manual Search eg
Arabsat 2B--->ok--->
Transponder frequency
:1291
Polarisation
: Horizontal
Symbol Rate
: 6000
FEC
: automatic
Network Search
: yes
ok--->now the search will start--->found two stations etc..
The difference with methode 1 is that you can use now the direct frequency like 1291
The Nokia 9500 and 9200 (patched with
dr Overflow)(info pe1chy)
Adjust the LO to 10000
Adjust the Sr to 6000
Adjust the FEC to 3.4
The signal meter should now indicate a signal
Start searching at the transponders
and that should do the job
Note : All receiver parameters I have
are in Dutch so they are "free translations".Hopefully they are
understandable.
