How to get the Nebula Electronics DigiTV, Pinnacle PCTV Sat, Twinhan DST + clones working | ||
========================================================================================= | ||
How to get the Nebula, PCTV and Twinhan DST cards working | ||
========================================================= | ||
|
||
1) General information | ||
====================== | ||
This class of cards has a bt878a as the PCI interface, and | ||
require the bttv driver. | ||
|
||
This class of cards has a bt878a chip as the PCI interface. | ||
The different card drivers require the bttv driver to provide the means | ||
to access the i2c bus and the gpio pins of the bt8xx chipset. | ||
Please pay close attention to the warning about the bttv module | ||
options below for the DST card. | ||
|
||
2) Compilation rules for Kernel >= 2.6.12 | ||
========================================= | ||
1) General informations | ||
======================= | ||
|
||
Enable the following options: | ||
These drivers require the bttv driver to provide the means to access | ||
the i2c bus and the gpio pins of the bt8xx chipset. | ||
|
||
Because of this, you need to enable | ||
"Device drivers" => "Multimedia devices" | ||
=> "Video For Linux" => "BT848 Video For Linux" | ||
=> "Video For Linux" => "BT848 Video For Linux" | ||
|
||
Furthermore you need to enable | ||
"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices" | ||
=> "DVB for Linux" "DVB Core Support" "Nebula/Pinnacle PCTV/TwinHan PCI Cards" | ||
=> "DVB for Linux" "DVB Core Support" "Nebula/Pinnacle PCTV/TwinHan PCI Cards" | ||
|
||
3) Loading Modules, described by two approaches | ||
=============================================== | ||
2) Loading Modules | ||
================== | ||
|
||
In general you need to load the bttv driver, which will handle the gpio and | ||
i2c communication for us, plus the common dvb-bt8xx device driver, | ||
which is called the backend. | ||
The frontends for Nebula DigiTV (nxt6000), Pinnacle PCTV Sat (cx24110), | ||
TwinHan DST + clones (dst and dst-ca) are loaded automatically by the backend. | ||
For further details about TwinHan DST + clones see /Documentation/dvb/ci.txt. | ||
i2c communication for us, plus the common dvb-bt8xx device driver. | ||
The frontends for Nebula (nxt6000), Pinnacle PCTV (cx24110) and | ||
TwinHan (dst) are loaded automatically by the dvb-bt8xx device driver. | ||
|
||
3a) The manual approach | ||
----------------------- | ||
3a) Nebula / Pinnacle PCTV | ||
-------------------------- | ||
|
||
Loading modules: | ||
modprobe bttv | ||
modprobe dvb-bt8xx | ||
$ modprobe bttv (normally bttv is being loaded automatically by kmod) | ||
$ modprobe dvb-bt8xx (or just place dvb-bt8xx in /etc/modules for automatic loading) | ||
|
||
Unloading modules: | ||
modprobe -r dvb-bt8xx | ||
modprobe -r bttv | ||
|
||
3b) The automatic approach | ||
3b) TwinHan and Clones | ||
-------------------------- | ||
|
||
If not already done by installation, place a line either in | ||
/etc/modules.conf or in /etc/modprobe.conf containing this text: | ||
alias char-major-81 bttv | ||
$ modprobe bttv i2c_hw=1 card=0x71 | ||
$ modprobe dvb-bt8xx | ||
$ modprobe dst | ||
|
||
The value 0x71 will override the PCI type detection for dvb-bt8xx, | ||
which is necessary for TwinHan cards. | ||
|
||
If you're having an older card (blue color circuit) and card=0x71 locks | ||
your machine, try using 0x68, too. If that does not work, ask on the | ||
mailing list. | ||
|
||
The DST module takes a couple of useful parameters: | ||
|
||
Then place a line in /etc/modules containing this text: | ||
dvb-bt8xx | ||
a. verbose takes values 0 to 5. These values control the verbosity level. | ||
b. debug takes values 0 and 1. You can either disable or enable debugging. | ||
c. dst_addons takes values 0 and 0x20: | ||
- A value of 0 means it is a FTA card. | ||
- A value of 0x20 means it has a Conditional Access slot. | ||
|
||
Reboot your system and have fun! | ||
The autodetected values are determined by the "response string" | ||
of the card, which you can see in your logs: | ||
e.g.: dst_get_device_id: Recognize [DSTMCI] | ||
