We are working on a DiSEqC implementation, where we are using STi7109 as a master, in the board also we are having a LNB controller (LNBH23) . Bus supply is fed through LNBH23.In DiSEqC bus specification it is given that command 0X21 (Set VR)will set the LNB in vertical polarisation.
My doubt is if I want to set the LNB polarization then it is enough to send that particular command in bus or i need to change the voltage level(13 V/ 18 V) in the bus.
