Hi Hans Petter,
thank you for the patch, but i do have severe problems with it..
First of all, i have to explain that i dont have any access to sat equipment at all - so i've to rely on understanding whats going on in even small patches or pieces of w_scan as good as i can. What i don't understand, i will not apply.
I cannot test anything sat related, i use terrestric and cable only.
I was trying to translate your settings for vdr diseqc.conf into human readable things..
<snip>
LNB.A 11700 V 9750 t F W45 v W15 W45 F W45 v W15 W45 t W45
</snap>
define command chain for 'LNB.A' && frequencies below 11700MHz (=lowband) polarization vertical as follows
1) '9750' use LNB LO 9750MHz // OK, translate lowband 10700MHz..11700MHz to 950MHz..1950MHz)
2) 't' 22kHz tone off // this will select lowband on a multiband LNB. correct.
3) 'F' lnb voltage off // why switching *off*, if we want to program the LNB? wrong.
4) 'W45' wait 45msec //
5) 'v' lnb voltage 13volts // vertival = 13V, correct.
6) 'W15' wait 15msec // hmm..
7) 'W45' wait 45msec // ? wait again? and 45msec? 15 should be enough by spec.
8) 'F' lnb voltage off // why again switching LNB *off*?
9) 'W45' wait 45msec // wait again
10) 'v' lnb voltage 13volts // vertival = 13V, correct. But that was set before..? I'm confused. You lost me here completely..
11) 'W15' wait 15msec // hmm..
12) 'W45' wait 45msec // ? wait again?
13) 't' 22kHz tone off // if we hadnt switch off the LNB, we wouldnt have to set it again to low band.
14) 'W45' wait 45msec
I cannot find any diseqc switch related command here; so that means something is intrinsic wrong on this line. As soon as a
diseqc switch is inside your equipment, it *has* to be controlled *every time* you change satellite, low/high band or polarization. And it should be a 0x2X command if i read the diseqc spec.
If i compare to w_scan's patch it does..
2) 22kHz tone off tone off
3) lnb voltage off
4) wait 45msec
5) lnb voltage 13volts
6) wait 15msec
7) wait 45msec // that doesnt make sense to me.
8) lnb voltage off
9) wait 45msec
10) lnb voltage 13volts
11) wait 15msec
12) wait 45msec
13) 22kHz tone off
14) <missing> // the wait 45msec is missing compared to above.
If i compare to the other switch positions, i can find two diseqc commands:
MASTER_CMD_NO_RESPONSE, ADDR_ANY_LNB, 0x26, 0x00, 0x00, 0x00 // 0x26 -> Select Satellite position B (or position D)
MASTER_CMD_NO_RESPONSE, ADDR_ANY_LNB, 0x27, 0x00, 0x00, 0x00 // 0x27 -> Select Switch Option B (e.g. positions C/D)
But what i'm actually missing is switching back to 'Option A', once you switched to 'Option B'; in the same way i miss
selecting position A/B:
MASTER_CMD_NO_RESPONSE, ADDR_ANY_LNB, 0x22, 0x00, 0x00, 0x00 // 0x22 -> Select Satellite position A (or position C)
MASTER_CMD_NO_RESPONSE, ADDR_ANY_LNB, 0x23, 0x00, 0x00, 0x00 // 0x23 -> Select Switch Option A (e.g. positions A/B)
For me it looks like, that you try to circumvent in a wrong way using the missing diseqc commands. If (only if..) i understand
your coding correctly, your switch looks like a 2x2 matrix. The first one selecting A/B vs C/D, the second choosing the first or second of those preselected.
>From a more general point of view..
- function name 'setup_kjaerulff1_switch' << i dislike naming which is not self explaining. Naming should be consequently english.
- a new command line switch. I tend to remove command line switches rather than adding new ones. Less is more.
And even if a new is really necessary it should be '-D Nx', with x a new character and N = 0..3
- the patch doesnt include the new command line switch in the man page
- function setup_switch should handle this new kind of switch, but setup_kjaerulff1_switch should not be called directly.
- the '0x26' and '0x27' should use their already defined macros: CMD_SET_POS_B and CMD_SET_SOB.
Using this macros already gives me hint, that you need CMD_SET_POS_A and CMD_SET_SOA also if you need the others.
at this point, i think i cannot integrate your current patch as it is.
Too many open questions, no datasheet and i cannot figure out by myself.
If you could find out and answer the open questions, i would look again at this topic.
Thanks a lot for forwarding @ Juergen.
cheers and have phun,
wirbel
