No communication from Primary Decoder E143-0


Re: No communication from Primary Decoder E143-0

Cant help you without knowing more about of your install.

What LNB do you have? Where is the diplexer installed? It should be behind the Explora 1.

The 5 series decoder MUST be connected to a unicable port. Therefore you MUST have a SLNB or a 24-1Z switch installed for it to work properly.


Octo LNB; 2 by 2x4 MS; 2 by ES 5-2; Dedicated PSU for LNB, ES's, MS's; HD PVR 4P x 2; Explora 1; DSD 660; FSM

No communication from Primary Decoder E143-0

With my explora1being the primary decoder and 5-series being the secondary decoder with a combiner, i keep getting error E143-0 No communication from primary decoder. All effort has been made to change the cables and even swapped the secondary decoder to new one. Can anyone help to solve this?

Also is it true that both primary and secondary decoder MUST not be 15 meters apart for the secondary decoder to receive HB?
