Dean,

Please refer to the timing diagram on the datasheet here.

See how +12VDC in is always ON? It's not the +12VDC IN controlling the board REM out & +12VDC out. It's the REM IN signal which will trigger the delayed output.

See updated diagram below of what we mean using a switch to control the turn ON/OFF sequence.

Hey guys.

Great work, everything makes sense with a diagram.

I appreciate the effort and will post an update when i get home in a few months.

Cheers
Dean

i'm using dcisolator in my car and I also don't have the 3 sec delay

I basically use the devteam schematic, I have 12v from the battery to power up the board and 12v from my head unit on the remote input.... but the rem out turn on instantly without delay :pinch:

@ Chispakkiuie (boy this is hard to write! :-)

Please show your diagram of how you're wiring your miniDC. Dean in the above didn't use the miniDSP as typical since it was used for a hifi setup (different application). In a Car audio, it shouldn't be a problem. You really need to make sure that you're using +12V out though.

modifing the picture I thought that maybe that I've to connect the amplifiers' relè to +12v out togheter minidsp board... or not ?

Yes this diagram seems correct. What's the note "to a relay turning on the amplifier". Did you make sure of the current limit (100mA). If it's too high, it wouldn't work.
Also, please clarify what you mean that it doesn't work. Is that at REMIN low to High or High to low transition that you're not "seeing" the delay.
