Making it Work

Firmware

Supplied by manufacturer (v 1.22.82.0)

Prof supplies a zip file which contains the firmware file dvb-fe-cx24116.fw which is version 1.22.82.0.

Copy this file to /lib/firmware and reboot your computer or reload the driver modules.

Supplied by TeVii (v 1.23.86.1 latest known version on december 12th of 2009)

Firmware v1.23.86.1 is available with the TeVii S460 Linux driver at http://tevii.com/Support.asp. It works with this card.

wget http://tevii.com/100205_linux_tevii_ds3000.rar
unrar x 100205_linux_tevii_ds3000.rar
cp dvb-fe-cx24116.fw /lib/firmware/dvb-fe-cx24116-1.23.86.1.fw
ln -s /lib/firmware/dvb-fe-cx24116-1.23.86.1.fw /lib/firmware/dvb-fe-cx24116.fw

You can also have a look at WinTV-HVR-4000. It uses the same firmware.

Firmware loading

On first usage, read or tuning, of the driver the module Conexant CX24116 will try to load a firmware file called dvb-fe-cx24116.fw which must exist in /lib/firmware. For instructions see Firmware section. Because of this upload the first tuning will take a bit longer beacuse it is waiting for the firmware upload.

On succesfull load you will see the following message in your kernel log (Example in dmesg this if for fw version 1.22.82.0)

#> dmesg | grep -i firmware
cx24116_firmware_ondemand: Waiting for firmware upload (dvb-fe-cx24116.fw)...
firmware: requesting dvb-fe-cx24116.fw
cx24116_firmware_ondemand: Waiting for firmware upload(2)...
cx24116_load_firmware: FW version 1.22.82.0
cx24116_firmware_ondemand: Firmware upload complete

Using it

Scanning

Scanning can be done with the scan-s2 application.

To get working result please allways add the -X option to the scan-s2 application. It will only scan the transponders in your input file but without this option it will not find any channels.

-X      Disable AUTOs for initial transponders (esp. for hardware which
        not support it). Instead try each value of any free parameters.

And specify a full scan line (with rolloff and modulation type) in your input file for DVB-S2 transponders(example for Astra-19.2E):

# Astra 19.2E SDT info service transponder
# freq pol sr fec
S2 10818000 V 22000000 2/3 35 8PSK
S2 10832000 H 22000000 2/3 35 8PSK
S2 10862000 H 22000000 8/9 35 8PSK
S2 11023000 H 22000000 2/3 35 8PSK
S2 11171000 H 22000000 2/3 35 8PSK
S2 11303000 H 22000000 2/3 35 8PSK
S2 11362000 H 22000000 2/3 35 8PSK
S2 11436000 V 22000000 2/3 35 8PSK
S2 11914000 H 27500000 9/10 35 QPSK
S2 12522000 V 22000000 2/3 35 8PSK
S2 12581000 V 22000000 2/3 35 8PSK
S2 12670000 V 22000000 2/3 35 8PSK

Tuning

Tuning can be done with the szap-s2 application.

To tune to DVB-S2 channels always use, at least, the following szap-s2 options:

      -S        : delivery system type DVB-S=0, DVB-S2=1
      -M        : modulation 1=BPSK 2=QPSK 5=8PSK
      -C        : fec 0=NONE, 12=1/2, 23=2/3, 34=3/4 35=3/5 45=4/5 56=5/6 67=6/7 89=8/9 910=9/10 999=AUTO
      -O        : rolloff 35=0.35 25=0.25 20=0.20 0=UNKNOWN

Example:

 #> szap-s2 -c Astra-19.2E.channels.conf -S 1 -M 5 -C 23 -O 35 "Astra HD"
