esilviu, so I have played with my DCDC USB today. It's true that Vaux can be programmed to start with a delay. But it's only possible in script mode. In script mode, ignition is a hard on/off switch of the PSU, which means when ignition goes low, Vout and Vaux will be out immediately. We don't have the off-delay and hard-off as we do in automotive mode. I didn't test PWR because there's no meaning of it when Vout is out immediately after ignition goes low.
However there's one unknown automotive setting in the "Settings" section: "Automotive Mode: Thump timeout". And the description is "THUMP timeout, switching off the audio amplifier during motherboard startup/shutdown":
This is undocumented in both the basic and advanced manual. I suspect it's one of the pins near the state LED. But again, it's not documented. Does anybody have an idea? I may want to send en enquiry to mini-box since they have 30 days support.
Having said that, I found an amp on ebay and looks like it doesn't need the anti-thump thing?
Note: "Delay function,no need to add speaker protection"
I don't really understand what does that mean, but it sounds quite interesting to me. Does anybody have an idea?
