TechniSat Air2PC-ATSC-PCI
There are actually two different PCI card variants that were produced by TechniSat that bear the identical Air2PC-ATSC-PCI name. Both Air2PC models are well supported under Linux. These are older cards (circa 2001 ? and 2004 ?) that are no longer manufactured, and have been superseded by the presently offered AirStar-HD5000-PCI model.
The origianl "Air2PC ATSC PCI" reference card was designed by B2C2 and adopted by TechniSat for manufacturing. TechniSat never listed the Air2PC cards on their own website's product pages (they only list the models' DVB-T counterpart, the AirStar 2 PCI). Rather, one finds information about these ATSC cards on the BBTI website (TechniSat's source for North American sales and distribution). Evidently, instead of marketing the cards using TechinSat's "*Stars" product lineup nomenclature, BBTI elected to use the orignial B2C2 naming scheme.
Air2PC-ATSC-PCI (1st rev)
The original Air2PC model used the B2C2 FlexCop2 or FlexCop2b PCI interface chipset with a Broadcom 3510 demodulator (which is visible on the face of the card's PCB).
You will often find this revision for sale on eBay, and in many cases being sold by BBTI themselves (see the notice on their webpage for further details).
This card requires a firmware file (dvb-fe-bcm3510-01.fw) for the demodulator, which can be obtained from the LinuxTV downloads section. Once the download is complete, place a copy of the firmware file in your /lib/firmware directory.
Air2PC-ATSC-PCI (2nd rev)
The later revision/variant of the Air2PC card also used the B2C2 FlexCop2 or FlexCop2b PCI interface chipset, but was updated with a Samsung TBMV30111IN NIM that featured a Nxt2002 demodulator.
This card requires a firmware file (dvb-fe-nxt2002.fw) for the demodulator, which can be obtained using the get_dvb_firmware perl script included in the kernel sources:
# cd /[kernel source directory]/Documentation/dvb/ # perl get_dvb_firmware nxt2002
Once the download is complete, place a copy of the firmware file in your /lib/firmware directory.
