Notes and Examples
When performing a scan on the DTV-TX02-DVB-S, the following data should be entered into the web pages:

Frequency – range 0-2150

Symbol Rate – range 0-40000

FEC – Leave at 7, as this will automatically detect the FEC.
Hence looking at a typical program on Astra 2D (see: http://www.lyngsat.com/astra2d.html )

Ch4 is listed as 10.714GHz S/R 22000 Horizontal

As horizontal an LNB supply of 15.5 to 18V should be injected.

The frequency in the DTV web pages should be entered as 964 (10714-9750), and as this falls
between 950-2150MHz no tone is required.

The Symbol Rate should be entered as 22000.

The FEC should be entered as 7 (the default setting).
Another example:

E4 listed as 10.729Ghz S/R 22000 Vertical

As vertical an LNB should be applied between 12.5 to 14.5V.

The frequency should be typed in as 979, and once again no tone is required.

The Symbol Rate should be entered as 22000.

The FEC should be entered as 7 (the default setting).
If the frequency to be entered into the web pages is greater than 2150MHz, the Local Oscillator frequency
would need to be changed from 9750MHz to 10600MHz, by injecting 22kHz tone.
