After looking back at the specs I am a bit confuse about "commited" and "uncommited" also. I thought a standard port was uncommited, but 38 is what I have been using. Someone else may need to jump in, but the 4 commands for the 4 ports for my switch are

[E0 10 38 F0]
[E0 10 38 F4]
[E0 10 38 F8]
[E0 10 38 FC]

The chart in the pdf for yours indicates maybe F0,F1,F2,F3 is correct for yours. you will have to just test and see.

As for the stacking, Looks like you have "universal" lnb. They cover a wider band then a standard and do it in 2 steps. It should have a 22Khz switch built in and you select between lo and hi with the tone command (t/T) wwhich you have at the end of your lines.

Horizontal and vertical polarities are selected with the voltage (v/V). Band stacked LNBs switch by changing the local oscillator only. You don't have a BS lnb. I would recommend simplifying your commands and first working out which address are used (0,4,8,C or 0,1,2,3). Then if you have problems with it not always switching, you look at repeating the commands.

S23.5E  11700 V  9750  t v [E0 10 38 F0] W15 t
S23.5E  99999 V  10600 t v [E0 10 38 F4] W15 T
S23.5E  11700 H  9750  t V [E0 10 38 F8] W15 t
S23.5E  99999 H  10600 t V [E0 10 38 FC] W15 T

Also, S23.5E ?? You can't see that sat from north america. The best you could hope for is around 30-40w to around 150-160w and that is iffy.

My diseqc.conf file is slightly different from your example, so I
attached it to this mail.
There is example, where mini A and mini B command is used. But i didn't
find anything about this command in eutelsat documentation nor source
code (these commands are implemented as ioctl() in fronted source code

Not sure if this is what you mean, But for an example, The dishnetwork
dual lnb has a switch in it and responds to F1/F5 vs a standard switch
which would be F0/F4. The standard switch will only respond to F0/F4
while I think the DN switch will respond to ether set. So Putting a DN
dual LNB on a standard 1x4 switch woudl look like this:

S110.0W 99999 R 11250 t V W15 [E0 10 38 F4] W25 [E0 11 38 F5]
S110.0W 99999 L 14350 t V W15 [E0 10 38 F4] W25 [E0 11 38 F5]
I don't understand why in our example F4 is port number, but in my
config file the last number is incrementig with next
S23.5E 11700 V 9750 t v [E0 10 38 F0] W15 [E1 10 38 F0] W15 [E1 10 38
F0] W15 t
S23.5E 99999 V 10600 t v [E0 10 38 F1] W15 [E1 10 38 F1] W15 [E1 10 38
F1] W15 T
S23.5E 11700 H 9750 t V [E0 10 38 F2] W15 [E1 10 38 F2] W15 [E1 10 38
F2] W15 t
S23.5E 99999 H 10600 t V [E0 10 38 F3] W15 [E1 10 38 F3] W15 [E1 10 38
F3] W15 T
I would supposed, that if it's connected to one diseqc relay input, that
there will by same number everywhere.

Because this is for a band stacked DishPro LNB, you change the LO to
select R/L and keep the voltage up. E0 10 38 F4 is the command for a
standard 1x4 switch to use the second port (ports are FO, F4, F8, FC).
Then you have a short pause to allow time for the first switch to
select that port. Then you send the second command. Not also the "t"
for tone control. You can stack a tone switch in also. Have it select
between one of 2 1x4 switches to get you 8 ports. You can only have 1
tome switch in any given path because they can not be addressed. Ether
you send tone or you don't.
How can I use tone to stack switch(how to write diseqc.conf line)?
According eutelsat documentation tone is send after binary command in

Now, I have 4 input diseqc switch controlled by line in attached
diseqc.conf file. According manufacturer
this switch is controlled from a receiver with "Position" and "Option"
commands. According table in chapter 8.3. Command Byte of eutelsat
docuemntation positon and option commands are numberes 22, 23, 26, 27.
But these commands aren't use in my diseqc. Instead it is used 38
command which mean "write too commited switches". But again I don't know
what is "commited" and "uncommited" switch.

To stack switches you need what is called committed switches for the
secondary switch. They us a different address. If additional switches
are needed, make sure each in the string will pass commands not
addressed to them. As far as I know they all should.

So, I have commited switch (and don't know what is mean). Now i want to
buy one two-input-diseqc-relay and put it between dvb-s card and
four_input-diseqc relay. Which one two-input-diseqc-relay I should buy?
The one controlled by position, or one controlled by option
And how diseqc.conf line will look like? And how to not interference
with postiono/option command of four-input-diseqc-relay? I can buy this
that can be controlled by postion or tone-burst commad. But still don't
know, how to write diseqc line for it and how to don't interference with
position command of four-input diseqc-relay with position commad of this

Can anybody help me with this questions?

I read, that is posible connect diseqc relay to cascade (one two input
relay and two four input relay for example). I read that not all
receiver are able to use it (linux based, like dreambox are).
I would like to setup one two input relay and one four input relay to
get five input for convertor in VDR. Is anybody familier with
diseqc.conf and Can you help me how to set it up? Now, I use four input
relay only, but I don't know what number in diseqc.conf file mean.

If this will be posible I would like to use diseqc relay input to often
watched tv stations and motor to rotate whole dish to different postion
for experimentation and use only central converter for watching. Would
be possible to use VDR for this purpose too?

Thans for your advise
