[vdr] Re: vdr and motorised dish

I have a HH100, how would an actual diseqc.conf look like?
You have 2 possibilities, one now and one in the next future (a week or two):

1) Use actual rotor-plugin (v. 4): you can move the dish East/West, store the position, go to a position. In diseqc.conf you will find commands like: E0 31 6B XX, where 6B is the Goto To Position command and XX is the stored position. Internally, positions are stored as steps of the step-by-step motor inside the rotor from the 0.
The procedure is long and tedious !

2) Use next rotor-plugin (v. 5) supporting the GotoXX diseqc command. It's also called USALS or diseqc 1.3. Are commands like: E0 31 6E E0 60 - means go 6 degrees east from the 0. In this way you can specify exactly where to point your dish. But it'n not so easy. Infact the patch in the list didn't take care of Earth being a "ball": satellites are on an arc and not on a line, from viewpoints different from the equator, so you have to use trigonometric calculations.
Next version of the rotor plugin will take care of this. You will indicate your position (lat and longitude), select a satellite present in sources.conf and if your rotor is correctly setup, it will point the right satellite ! Satellite position data is taken directly from sources.conf - you can modify it at will ! This will work from the plugin menu. You can copy the diseqc commands in diseqc.conf file if you want to move the dish by zapping (I don't want, for example). I don't know if the plugin author will create other methods.... I am in contact with him, I'm not the developer !


Probably the best way to use the rotor will be using 2) to point the satellite, then with the plugin move the dish to get the better signal then store the position and recall the positions in diseqc.conf.
