Hi Ray
Not sure about the large version decoders but this is what it says for version 5.0 - you need to tell the decoder the SSP (smart power pack) is there and which output function is being used, which is AUX 9 for a loksound 5 and AUX 7 for a Locksound 5 micro. First ensure CV31=16 and CV32=0 to gain access to the correct index, and for a Loksound 5 set CV339 to 31, and for a Loksound micro set CV323 to 31.
