DC-DC Car Power for Mac Mini - Page 4

I guess I don't understand.

Does the P1900 have a shutdown timer? I looked at the link for the 1280, and I saw that it will shut the box down if the battery voltage drops under 11V. However, what about a hard 30-minute turn-off? Is it possible? (i.e., screw open files, we just want it turn off hard.)

Yes. The SSC will wait a pre-defined period of time (either 6 seconds or 15 minutes, jumper selectable) before it begins to shut down. After the shutdown sequence has ended, all power is removed from the Mac. However, if you select the "standby" mode (jumper selectable) the P1900 will continue to provide power to the Mac to keep the RAM alive. This is a low-power mode (ie fan off) so that any current draw over about 1 amp will cause the P1900 to fully shut down.

The Installation Manual for the P1280 describes this is more detail.

Wonderful!

I'll poke around at possible UPS installations, or auxiliary battery installs, but if your power supply has a 15-minute cutoff, I might go that route instead. I think I'm too lazy to put together an Aux battery.

Hello MikeH and all. I was crusin the web looking for just this exact connector and came across this great site. I've read all pages and then remembered that my buddy is an ADC member (Apple Developer Connection) and has access to information on where to aquire these pieces through Apple. I put in a request to him and hope to hear positive news soon. Will keep everyone posted.

That would be most helpful! Please let us know what you find.

for all it's worth, I put through a request through apple DTS (what you call ADC) last week.. The DTS engineer was on vacation, should be back next week. Apple will publish a developer note on the macmini, the question is will DTS be allowed to post the connector info..(after working in DTS for 5 years, I can tell you it is hit and miss with engineering mgmt..) Product mgmt, might decide that it want to be picky about this info.. dont ask me why.

putting in the ADC request will probably cost him some money, unless he has a open account, anyhow, another request can only help the politics. we'll keep on them.
