E 48 error on single view decoders


Re: E 48 error on single view decoders

No worries Geoff, I just saw the clash of info. Guess we'll find out more in time.

I've said more about all this in the default thread we're using re the update.

@krugie, is this what you have??


No I have an octo-lnb with 8 cables going from there to two differnet 5.2 swiches. 5.2 Switch A has 2 x Explora 1s and a HD PVR connected to it (one Explora 1 and the HD PVR in Xtraview and the other Explora 1 standalone) with 5.2 Switch B only having 1 standalone Explora 1 connected to it (no Xtraview).


Octo-LNB to 24-1z/5.2 switches. Explora1 (Prim) & HDPVR 2P (Sec), Samsung 55" UA55F8500 Smart 3D LED TV, HDMI picture & audio via Onkyo TX-NR626

Re: E 48 error on single view decoders

What you say about the signal level not being good enough confirms my view that this process will only work flawlessly IF All the decoders are OFF to start with, and then one decoder at a time is powered up.

Sorry B, that is the only way I see this method working without the typical scenarios the moderator explained. 

Must get to see one of these 3-way Uniview setups for myself soon.

@krugie, is this what you have??

Re: E 48 error on single view decoders

I would think that after a reboot that involved a reset to defaults, the decoders would all default to decoder number 1.  that would explain the conflicts!

It would be great if you could provide us with some screenshots of the page where all the smoke and mirrors stuff is going on.

Re: E 48 error on single view decoders

Interesting thread! So the decoders have the choice of 3 settings, labelled 1,2,3. Presumably each of these settings then has predetermined allocations of userbands and frequencies, which then it goes ahead and configures without the user having to do so?

I was being a litte too clever with this auto config idea.

Presumably Allowing for three Explra decoders in Uniview;

decoder 1 setting is for userbands 0,1,2 

decoder 2 setting is for userbands 3,4,5

decoder 3 setting is for userbands 5,6,7

Big deal! Not auto at all just an utomated manual method.

My scenerio said that the decoders would "interogate" the SLNB, find the userbands 0,1,2 are in use for primary, then "automatically" configure the next. If it was a single view decoder, it would select 3,4.

Then when the last is powered up it would check, see that 0,1,2,3,4 are in use and now select 5,6 for the last one.  That is what I would call automated! 

Nevertheless give me the manual method any day!

Re: E 48 error on single view decoders


I had powered down both of the single view decoders a number of times but on startup they did not automatically chose a free tuner (decoder #). Seems this has to be changed manually or via the wizard(s) - unless the Explora can change them during set-up. ...)


Ultimately they're still working at the moment :-)




Re: E 48 error on single view decoders

Thanks Geoff, basically what I've now done as per the (long) description below.


Should have checked Info Central on all 3 decoders to start with for the decoder number - we live and learn - the installers had done that (presumably).


Seems like some of the decoders were using the same tuner 'Decoder number' (maybe all 3 the same) but why this occurred I don't know because everything was working perfectly at 00:30 hours yesterday morning and then 'all fall down' at 4:00 hours when i turned one of the TVs on.

Also curious why support didn't ask me to check when I phoned (twice).


Your comment on turning off the decoders and turning each one on in turn is a good one. if it happens again I'll try that route and hope they 'auto-sync with the tuners. Otherwise back to the manual method.


Re: E 48 error on single view decoders

Thanks for the detailed feedback Fred. Unfortunately it will be mostly due to problems MC are having with current new software.


Don't be too concerned about the remotes issues, it will have been setup fine, but it is possible something got messed with now - you'll have to see.


MC - I'm now with Geoff re his earlier comments, far too complex for easy use so not worthy of the term "auto" at all. Even your specialist advising here via our Mod didn't know enough, Fred was just fortunately able to work it out.


Re: E 48 error on single view decoders

OK. The Mod was on the right track - almost.

This works with Explora 2 and 2 single view decoders (I think they're type '33') but try at your own risk (as I haven't checked all possibilities).

Part 1

On each decoder hit the DSTV button.

Navigate to Help -> General Info -> Information Central

On the right of the screen that pops up, check almost at the bottom for "Decoder Setup Type". There are 3 possible decoders, 1, 2 and 3.

Make sure each decoder has a different "Decoder Setup Type". If 2 are set the same you'll have a problem (I think as a non expert). Make a note of which 2 decoders have the same Decoder number and which decoder number is not used by any of them.


If 2 are the same then proceed as follows:

Part 2

On one of the decoders (that has a conflicting decoder number) navigate to settings -> Satellite Settings -> Home Network.

Select "Launch Installation Wizard".

Satellite should be IS20 (in this part of the world). Press OK.

Next page choose "Quick Setup"

Select one of the unused "Decoders (1, 2 or 3)" that you determined from Part 1 (under Help -> General Info -> Information central).

Press 'OK' and the decoder should start scanning.


Voila! (in my case anyway). I hadn't done Step 1 first so I can't be certain that 2 decoders had the same decoder number. I just changed them to my order of preference for the 3 decoders - well almost. On the Explora I chose 'Decoder 1' but it told me the signal strength wasn't good enough so I guess it was conflicting with one of the other decoders. I chose 'Decoder 3' and it worked. The other 2 single views have been set to 'Decoder 1' and 'Decoder 2' and are both working.

Ultimately it doesn't matter (IMO) what decoder is set to what number - they must be different.


But why after more than a year of 3 decoders the problem suddenly arose I don't know (no settings were changed) but I guess it was something to do with the 'enforced' daily re-boot these decoders have.


Another tip if you have a 3 decoder setup is to ensure that the 'TV' setting on the decoder remotes is diffenet. My single view decoders were set at TV 1 and TV 2 on the remotes but the Explora decoder remote kept changing the Single View 'TV 1' decoder - even though the decoders are in different rooms. Changed the one SIngle View remote to TV 3 and the problem went away. So the remotes should be set to different 'TV Numbers'.

Note though that the Explora is connected to 2 TVs - one in the lounge (via HDMI) and one in a bedroom (via Aerial wire) and the bedroom TV has a 'Magic eye' sensor to control the Explora remotely from the bedroom - which might have caused the problem in the first instance as the decoders are all connected via 'RF Out' for the Extra-view.


Anyway, hope this helps others.



Re: E 48 error on single view decoders

Great, so it's power up both secondaries simultaniously and then work on one at a time.


Personally I think this auto method is hardly worth its complexity, easier to do it manually IMO.

Maybe good for via call centre help though.
