No communication from Primary Decoder E143-0

Re: No communication from Primary Decoder E143-0

When next to the other decoder, how do you route the HB?  Have you made sure the Diplexer is correctly installed?

Could you attach a picture of the diplexer and screens shots of the XV configuration on both decoders please.

Re: No communication from Primary Decoder E143-0

@GeoffD,

Thanks for your effort.

All connection has been checked from LNB to both decoder with the cables being replaced with new ones again. Even the diplexer was placed behind the primary even moved behind secondary, still No communication from primary decoder. unless the secondary decoder is placed beside the primary before it can receive hearthbeat.

Any moment from now i guess im going to dispose these decoders cos this is frustrating.

Any joints in the cable runs? eliminate those with connectors and barrels. Check on all connectors especially the ones at the LNB. Chnage ports on the SLNB, BUT make sure all the unused ports have terminations on them ( Unicable)  Store the spare terminations on the universal ports -- they don't do any harm and protect the universal ports from the weather.

6-7 meters should not be a problem. No, the diplexer is normally placed right behind the decoder, BUT there is nothing wrong with you experimenting a bit.

Don't know if anyone has tried to place the diplexer close to the antenna, which might help, at a point protected from the weather and accessible.

Would be very interesting if you do try it and let us know .....  That is what DIY is about --- finding solutions that confound the "experts" .....  Smiley LOL

Re: No communication from Primary Decoder E143-0

@GeoffD; really appreciate you.

The signal strenght is still ok as i can view DSTV 100 and some free air channels very well on the secondary. The major concern is the HB between the two decoder. Im on 36B with installed LMX 500 with the distance 6-7 meters distance between the two decoder. Will be advisable if the diplexer is placed inbetween this distance?

BTW, those signal strengths are very low! You are going to have on going connectivity problems unless you can improve the signal strength values to the secondary decoder.

Okay so now that we have elminated any settings issues, we can move on to the next hurdle.

  1. Notice that you are on 36B which means you are somewhetre in ROA and not in SA? 
  2. Please comfirm which SLNB is installed The LMX 500 (4 unicable ports and 2 Universal ports) or the LMX 501 (3 unicable ports and 1 universal port).
  3. There is that cable length restriction with the Explora 1 which applies IF you want to make use of the LNB and its cabling for HB.
  4. The only other way around is to install the HB cable the old way, which means removing the diplexer from behind the Explora 1, running the HB cable separately from the RF OUT or RF IN port on the Explora, to the 5 series decoder, and then using the Diplexer behind the 5 series decoder in reverse to allow you to inject the HB signal into the LNB port on the 5 series decoder.
  5. Unfortunately, that means a separate HB cable between the two decoders. What is the distance over which you are trying to do this? Send me a PM if you dont want to place that info in the public domain.

Re: No communication from Primary Decoder E143-0

Okay so SLNB. The Explora 1 connected to Port A on the SLNB (which one?  The LMX 500 or LMX 501)? The diplexer connected the right way around?

The 5 series decoder ONLY works when connected to a Unicable port AND set for unicable/satcr, because it has two tuners and requires to be set to use two userbands NOT used by the Explora.

The Explora is the Primary I presume?  It should be using userbands 0,1,2 with frequencies 1210, 1420, 1680. Connected to port A on the SLNB.

5 series decoder connected to port B. Set its userbands to 3,4 with frequencies 2040, 1006.  The 5 series decoder will not function properly if connected to the universal ports ever.

The diplexer must be connected behind the Explora 1 IF you want to inject the HB signal onto the LNB cabling.

See the first post under the technical info section and the post on how to connect the diplexer as posted by Optimist.

Re: No communication from Primary Decoder E143-0

 

Thanks for your swift response, im having SLNB and the diplexer is installed behind the explora 1 but the 5 series is connected to Universal port of which im always having no signal when connected to Unicable port. Is there any other thing i need to do?
