TechnoTrend TT-budget S2-3200

A DVB-S2 PCI card from TechnoTrend.

This card supported in the stock kernel as of version 2.6.29 commit.

Overview

This card is apparently also available/rebranded as the TechniSat SkyStar HD.

Components Used

• NXP/Philips SAA7146 (PCI bridge)
• STMicroelectronics STB0899 (demodulator)
• STMicroelectronics STB6100 (tuner)
• STMicroelectronics LNBP21 (LNB supply and control IC)

It also supports an add-on CI slot.

Identification

Type

lspci -v

You should get lots of output, including a paragraph something like this:

04:01.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)
 Subsystem: Technotrend Systemtechnik GmbH S2-3200
 Flags: bus master, medium devsel, latency 64, IRQ 16
 Memory at febffc00 (32-bit, non-prefetchable) [size=512]

Drivers

This card supported in the stock kernel as of version 2.6.29 commit so you should start off by trying the standard 2.6.29 (or later) kernel and making sure that the appropriate kernel modules are loaded.

Only start looking at experimental drivers described below if you need more recent changes or fixes.

Status/problems

A problem with locking high symbol rate channels (DVB-S2 30000 3/4 transponders) has been reported a number of times, but has not been solved. http://linuxtv.org/pipermail/linux-dvb/2009-January/031673.html, http://linuxtv.org/pipermail/linux-dvb/2009-February/031779.html .

Such transponders can be found at Thor 0.8W and Hispasat 30.0W.

A way to use the similar (but USB) TechnoTrend TT-connect S2-3650 CI to help fix problem has been suggested here: http://www.spinics.net/lists/linux-media/msg01169.html .

Another way is to use 29999.999MHz for symbol rate. ( Successfully test with Eutelsat W2 / EuroBird 16E, Madagascar beam with OrangeTV)

Do you have the TT3200 or TT3650 ? Can you help debug the driver?

v4l-dvb/S2API driver

Since kernel 2.6.28, DVB-S2 support has been implemented in the Linux kernel by means of a new API, version 5, also known as S2API.

Try the latest linuxtv.org repository, which is known as v4l-dvb. Changes here will go into the next kernel version:

hg clone http://linuxtv.org/hg/v4l-dvb
ln -s v4l-dvb s2  [scan-s2 Makefile expects this]
cd v4l-dvb
make
sudo make install
sudo reboot

or alternatively s2-liplianin is usually quite up to date:

hg clone http://mercurial.intuxication.org/hg/s2-liplianin
ln -s s2-liplianin s2  [scan-s2 Makefile expects this]
cd s2-liplianin
make
sudo make install
sudo reboot

Scan for channels with scan-s2:

hg clone http://mercurial.intuxication.org/hg/scan-s2
cd scan-s2
[check the INCLUDE line in the Makefile points to the s2 directory]
make
./scan-s2 [options] -o zap dvb-s/[satellitefile] > ~/channels.conf

and tune with szap-s2:

hg clone http://mercurial.intuxication.org/hg/szap-s2
cd szap-s2
[check the INCLUDE line in the Makefile points to the s2 directory]
make
./szap-s2 [options] -c ~/channels.conf [channel]

Or install one of the main multimedia applications like Kaffeine or MythTV.

Multiproto driver

A driver using the obsolete multiproto API may be installed as follows.

Installing on Debian (2.6.18-6-686) etch with Multiproto diver (!!!DVB-S2 Don`t Work. Only DVB-S!!!). Install new Debian (2.6.18-6-686)

cd /usr/src
apt-get install linux-headers-2.6.18-6-686
apt-get install linux-source-2.6.18
apt-get install mercurial

hg clone http://jusst.de/hg/multiproto   [or maybe multiproto-plus]
cd multiproto
make
make install
reboot
dmesg
