My satellite equipment consists of dish with 4 Quattro-LNB's connected to a 17/8 Diseqc 1.0 Multiswitch.
Although this setup is quite common, AutoDiseqc fails to detect the satellites correctly on my Xtrend ET9200.

I wonder if an expert, familiar with the source code, could help?

That has nothing to do with code.

 

Whan is needed is a list, with per satellite position a transponder which can be locked that is absolutely unique amongst all sats in the list  (to avoid false hits.

 

You can find the current list here: https://github.com/O...toDiseqc.py#L25

 

p.s. not common enough, I've got two of those switches here, one new-in-box. Nobody's interested .

[Stan]

You've posted a link to SatFinder. I was talking about AutoDiseqc.

 

I know that unique frequencies have to be scanned. That is the case, so no problem with that.

Once, about 10 years ago, I noticed on some receivers that they not tune eDVBFrontendParametersSatellite.System_DVB_S2 or some eDVBFrontendParametersSatellite.FEC.

Or problem in 17/8 Diseqc 1.0 Multiswitch.

Could we clarify some basics first? Why is there an option in AutoDiseqc "Set voltage and 22kHz"? It is not needed in a simple Diseqc environment.

Sometimes it is needed in the simple mode… but maybe not when all is in the autodiseqc mode.

[Stan]

Simple mode is by definition without cascaded switches, right?

[littlesat]

It was there for >20 years at that time you had 22 KHz switches and the dmm7000 had a 12 V output for a relay.

[Stan]

Nevertheless, it should reliably detect the connected satellites in common configurations. And it doesn't.
Another annoying thing is, that it changes the selected configuration. When chosen A/B/C/D it should keep this mode after scanning, no matter what the result is.

Problem this

			if mode == "diseqc_a_b_c_d":
				list.append((self.indent % _("Port C"), nim.diseqcC, _("Select the satellite which is connected to Port-C of your switch. If you are unsure select 'automatic' and the receiver will attempt to determine this for you. If nothing is connected to this port, select 'nothing connected'.")))
				list.append((self.indent % _("Port D"), nim.diseqcD, _("Select the satellite which is connected to Port-D of your switch. If you are unsure select 'automatic' and the receiver will attempt to determine this for you. If nothing is connected to this port, select 'nothing connected'.")))
				if (nim.diseqcC.value == '3600') or (nim.diseqcD.value == '3600'):
					self.autodiseqc_ports = 4

Maybe

if mode == "diseqc_a_b_c_d":
  if self.autodiseqc_ports:
     self.autodiseqc_ports = 4

 

[Stan]

Satconfig.py?

 

I'll test...

Nope. Now you can select only Port A and Port B.in mode A/B/C/D.

[littlesat]

Sorry I cannot follow you…. Here I can find 1, 2 or 4 positions and the result is not
Connected on the one where nothing was found. I never discovered when you set abcd that it changes to ab and visa versa.

[Stan]

There must be a recent code change, that modifies the selected configuration depending on the scan results.

 

You can repoduce it. Set the config like in the attached screenshot and then select AutoDiseqc.

And what is the resulting screenshot….
I actually never liked that you could set auto individually and predefine some positions. Maybe it was always better to have just one option auto…. And when off you can set it individually. And when (afterwards) we have some positions show for where nothing was found nothing connected.

[Stan]

Ok, so once again the screenshots:

It's actually a good thing, that you can repeat scanning for only certain sat positions that may have not been detected at first scan. But it should work right!

The semi-automatic logic that kicks in after the scan and changes the selected mode should be removed.

[littlesat]

Issue is now confirmed and verified.
Sounds it limits to location where it find something only and not keep the ones you set manually before (it was never made for this).
Needs investigation.
Is at my todo list. First fix simplechannellist

OK. If you have time for it, there's a second issue: If only some of the Ports are set to automatic, AutoScan will assign wrong satellites to them.

 

For example, my actual satellite setup is this:   4sats_correct.jpg   63.41KB   0 downloads I should always get this result after AutoDiseqc. (if it works right)

 

Instead, when scanning Ports C and D only, I get this:

 before_scan_4sats.jpg   70.53KB   0 downloads -> AutoDiseqc ->   scan_2from4.jpg   49.75KB   0 downloads -> Result ->  after_scan_4sats_2wrong.jpg   65.08KB   0 downloads

 

 

[littlesat]

Yes…. You do something it was never made for…. And due to you can set it up like this, what you experience happens…  you find the ‘edges’ on something that is in there for >10 years or so and also in more images what nobody discovered…

[Stan]

Why am I always getting this attitude?

 

[..]  You do something it was never made for…. [...]

I am doing exactly what is was made for.
