Making it work

According to NetUp's product page, the device works with their fork of Linux kernel 3.0.

Check out linux kernel (experimental): 

git clone http://udev.netup.ru/git/v4l-dvb.git linux-2.6.35-netup
cd linux-2.6.35-netup
make menuconfig
make && make modules_install && make install

Change grub menu.lst config to boot new kernel (/boot/vmlinuz-2.6.35+).


Install firmware files into /lib/firmware folder: 

wget http://www.netup.tv/downloads/netup-dvb-t-c_firmware-v0.1.tbz2
tar xvfj netup-dvb-t-c_firmware-v0.1.tbz2
cp netup-dvb-t-c_firmware-v0.1/* /lib/firmware/

Tuning to DVB-C and DVB-T

Each port can be tuned to DVB-T or DVB-C using frontend0 or frontend1 accordingly.

For DVB-T use frontend0 

# tzap modul64
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
reading channels from file '/root/.tzap/channels.conf'
tuning to 578000000 Hz
video pid 0x0000, audio pid 0x0821
status 00 | signal 0000 | snr 0000 | ber 00000000 | unc 00000000 |
status 10 | signal 0000 | snr 001b | ber bf8ec9c8 | unc 00000000 | FE_HAS_LOCK
status 10 | signal 0000 | snr 001b | ber bf8ec9c8 | unc 00000000 | FE_HAS_LOCK
status 10 | signal 0000 | snr 001b | ber bf8ec9c8 | unc 00000000 | FE_HAS_LOCK

For DVB-C use frontend1 

# czap -f 1 modul64
using '/dev/dvb/adapter0/frontend1' and '/dev/dvb/adapter0/demux0'
reading channels from file '/root/.czap/channels.conf'
