Firmware
Firmware for both the demodulator and tuner are necessary. OpenELEC dvb-firmware collection includes firmwares for this device too. Note that when downloading the firmware files from the OpenELEC firmware collection it's necessary to click the name of the firmware file first and then the "raw" button to download the actual binary!
- dvb-demod-si2168-a30-01.fw
- dvb-tuner-si2158-a20-01.fw
Place the 2 firmware files in /lib/firmware.
CT2-4400v2
If you have the second version of the device, you will need a different firmware for the demodulator. The correct file for the demodulator firmware is dvb-demod-si2168-b40-1.fw and can be downloaded from the OpenELEC dvb-firmware collection.
IR Remote Control
The supplied remote control is supported by the driver.
