DISEQC Switch Help (1 Viewer)

[EW Thomas]

Hello ! I am a new user of MediaPortal and already a lover of it's features and performance!
I am changing my switching arrangement to eliminate all 22K switches since it's close to impossible to get them
to operate under MP. Anyway I need to know the definition of the switch settings. I could probably figure it out
by process of elimination but knowing the correct answer would sure speed up things

If anyone has been there and done that and wouldn't mind sharing their results I would greatly appreciate
being in that loop.

FWIW I'm located in the USA Eastern Coast.

BTW I have tried the same setup as mentioned in earlier posts and also tried 2 switches with the same end result. Unless it's a bad run of switches this is a puzzling mess


Thanks!!

Wayne

Hello and welcome Wayne

I am changing my switching arrangement to eliminate all 22K switches since it's close to impossible to get them to operate under MP.

Hmmm, I'm not sure that I'd recommend that.

Perhaps you could share the details of your setup to enable people to try to help you? In particular:

• Which tuner(s) do you have?
• Which satellites are you trying to receive with each tuner?
• How does each tuner receive each satellite (ie. switch and LNB details)?

Anyway I need to know the definition of the switch settings.

What do you mean by "definition"?
...and exactly which switch settings are you referring to?

Sorry if these questions seem obvious and silly. It's just that there are potentially 3 sets of settings that could affect 22 kHz switches... so it isn't exactly obvious what you mean.

FWIW I'm located in the USA Eastern Coast.

Unfortunately this doesn't really tell us much. What would be most helpful is if you could answer the questions above. That way we can offer direct and specific help, and you don't have to try and figure stuff out on your own.

BTW I have tried the same setup as mentioned in earlier posts...

Which earlier posts are these? (Please provide links.)
I can see one earlier post about EPG, but nothing about satellites, switches or DiSEqC...

...and also tried 2 switches with the same end result. Unless it's a bad run of switches this is a puzzling mess

I'm sorry you're finding things to be a puzzling mess. If you could just answer the questions above then we can help to unravel the mystery and get your setup working.

Kind regards,
mm

Sorry for the lack of data.. I am using a Prof 7301 Tuner Card in conjunction with a DS41 4X1 2.0 Compatible Switch.
Not using all ports at the moment and using 2 fixed dishes currently. This is a stand by / back up system .
One dish is pointed at 87° W SES 2 and the other dish pointed at 101°W SES 1

The SES 2 pointed dish is receiving KU and the SES 1 pointed dish is receiving C band.

KU input is routed to Port 2 of the switch . C Band input is routed to Port 4 of the switch.

The feed line goes through a ground block straight to the 7301

The post I mentioned previously is here https://forum.team-mediaportal.com/threads/diseqc-not-switching.32525/

The definitions I am seeking are those of the actual switch settings in MP such as 1BB, 1AA and so forth. Knowing what these
refer to in terms of relationship to Port A and such would greatly help the setup. I currently have the program working perfect and using just KU.
If I scan in C Band I lose my KU signal and C band scans in strangely... sometimes even as a KU frequency with the correct program ID and PIDS
but of course you can't view it Also somethings scan in under wrong ID's This is not that great of a problem since I verify the correct channel by the A/V PIDS and other parameters.

Both dishes are fixed dishes at the moment. Hopes are that once I have all the bugs worked out to cut it over to the main system so I can receive all the birds my area will allow,but the current LNB for KU there is a universal with 22K switching and that opens up a whole different Pandora's box that I'll cross later

Basic System info is as follows MP 1.13 Final
OS Windows 10 Pro
Motherboard Intel 946GZIS
HD 4500 Video Card

Core Duo 2.66 Processor
System Memory Currently at 2 Gb but will be expanding to 8Gb shortly.

KU Band LO 10750

C Band LO 5150

Hope this covers the basics of the problem,but if not let me know and I'll be happy to assist in getting whatever info you might need.



Best Regards,

Thanks for the details Wayne

I am using a Prof 7301 Tuner Card in conjunction with a DS41 4X1 2.0 Compatible Switch.

That combination should be fine, as that tuner supports DiSEqC 1.0 (4 port switching) in MediaPortal.

Not using all ports at the moment...

Okay, perfect.

The post I mentioned previously is here https://forum.team-mediaportal.com/threads/diseqc-not-switching.32525/

Right. That thread is more than 8 years old now. I'd completely disregard it at this point. Too many things have changed since then.

The definitions I am seeking are those of the actual switch settings in MP such as 1BB, 1AA and so forth. Knowing what these refer to in terms of relationship to Port A and such would greatly help the setup.

Okay.
The first number is the DiSEqC version - 1.0 (ie. 4 port "committed" switch commands).
The first letter is the DiSEqC "option".
The second letter is the DiSEqC "position".

In short, in your terminology:

• 1AA = port A
• 1AB = port B
• 1BA = port C
• 1BB = port D

I currently have the program working perfect and using just KU. If I scan in C Band I lose my KU signal and C band scans in strangely... sometimes even as a KU frequency with the correct program ID and PIDS but of course you can't view it Also somethings scan in under wrong ID's

Which "band" settings are you using for your Ku and C band scans?
(You should not be using the LNB override settings.)

Hopes are that once I have all the bugs worked out to cut it over to the main system so I can receive all the birds my area will allow...

Does this main system have a motorised dish?

...but the current LNB for KU there is a universal with 22K switching and that opens up a whole different Pandora's box that I'll cross later

Ahhh, now I see why you'd want to avoid 22k switches.

KU Band LO 10750

So a good "band" setting would be "NA Bandstacked Ku-Lo (FSS)".

C Band LO 5150

...and for this, "C-Band" will work fine.

Hope this covers the basics of the problem,but if not let me know and I'll be happy to assist in getting whatever info you might need.

It does indeed... and hopefully my response answers some (if not all) of your questions.

mm

Thanks for the great information. I guess you could say this is a "Proof Of Concept" setup at the moment
The system I'm using with MP has a standard 10750 LO KU LNB I will change the main to a standard lnb to simplify
things when I cut over to it.

Still wondering why that the scans for C Band are so corrupted. I have considered port leakage maybe as a cause
but being a brand new switch I wouldn't expect that.

I have to say that the MediaPortal project sure produces some excellent programs! Tons of features and it plays well with other
sources if I need to use them.. If I had any decent Terrestrial OTA here I would be in excellent shape with MP.

Thanks again for taking time to clarify a few things and answer several others

I wouldn't expect that either. Like I said in my previous response: it's very important to set the correct "band" setting [when you scan - changing it afterwards will have no effect].

If you'd like further help with this then feel free to provide log files for me to look at. A specific description of an example of corruption will also be required. For example, at date/time ABC I tried to tune scan transponder X, but TV Server found the channels from transponder Y. I need that level of detail in order to be able to help with a problem like this.

Thanks again for taking time to clarify a few things and answer several others

I'm happy to have been of service.

I'm using C Band 5150 for the CBand LNB and KU Circular 10750 for KU.
I seriously thought about using the one you recommended for KU when I initially
scanned in that lnb. Sure does sound like a jacked up LO doesn't it.

I will try to scan C Band Again and if it messes up as I suspect it will I will get the
logs to you for a look


Warmest Regards,

Wayne

Sorry to not have reported my success/failures It has been a messy week indeed!
Anyway I did manage to scan in MeTv and Heroes on C Band but I had to do it by specific transponder.
Blind scan wouldn't do it. Also I couldn't get Decades and Movies to scan in in any fashion.

Will get back to that when the snow melts But I'm lots better than originally
