Regarding DiSEqC

[mohanaprakash]

Hi

I am working in a STB product, where we are using LNB H23 as LNB controller.

LNB Register Details
PCL TTX TEN LLC VSEL EN ITEST AUX
0 1 0 0 0 1 0 0



My DiSEqC commands are working only when i set my LNB controller register value to 0x44. If set VSEL bit (18 V) also it is not working.


If anyone is having some input on this issue please send to me.


Regards

Way over my head. What part of the planet are you working on this project from?

What voltage are you seeing at the coax when VSEL=1? Is VCTRL connected to anything or is it floating?
