    Running OPUS off 12V battery

    I want to setup to carputer before i install it in my car, when i hook up the opus to a 12v source, can i get it to turn on by applying 12v to the ignition (yellow) line for a moment?

    12v to the ign line needs to be constant while the computer is running.

    first see this... FAQ: What is Spoon Feeding
    then read this... FAQ: How to Wire an OPUS PSU
    so to answer your question you'll get it to turn on, but the yellow wire needs a 12v signal to keep the opus on, once you remove that signal, it shuts off
    now for the mandatory smilies...

    i

    i was aware of how to install the opus in a car, my question was is the ignition 12v on constantly while the motor is running or is it momentary when the car turns on and off, like a relay.

    My question has been answered now. I thank you for that, however, i did preform a search before I posted this question, and did not find an answer.

    It seems as though everytime someone new around these boards asks a question they get flamed and told to do a search or people respond "this has been asked twice a day, SEARCH" , its a bit rediculous and does not make for a welcoming atmosphere. If you want people to become more interested in this hobby, which you should, you could be a bit more welcoming.

    lol - give him a month or two and see if hes telling people to search

    it can be annoying to be told that when you are a newbie but its also annoying when youve been here a while and you know the answer is perhaps a couple of pages back and could be quickly found with a search, and its obvious that they couldnt be bothered and posted, expecting others to spend time typing or searching for them.

    Why would we want more NOOBS in the hobby. We already have eniough.

    Please don;t say you searched, cause you obviously didn't. And, the opus instruction manuel is not only on thier website, but we have a detaild explanation about wiring ALL of the Opus units in the FAQ section.

    So tell me, how do you figure that a car supplies a momentary ignition signal. Tell me which signal/wire/circuit in your car is only momentary, besides the actual starter of course. Even better, what momentary signal is there that goes high for a second WHEN TURNING THE CAR OFF.

    AND, WE HAVE A NEWBIE SECTION, POST IN THERE IF YOU ARE A NOOB.

    ha, you guys are jerks.

    e46 wiring harness dont use the yellow wire, u want to use the red one. the yellow is always on, and is very weak. the red is the 12v that is only live on the key turn
    Go on and do it, do it, Do it 'til you're satisfied,
    Whatever it is, do it, Do it 'til you're satisfied.

    Hes not talking about the cars wiring harness, he is talking about the Opus wiring diagram.

    WHile you might not be a jerk, you might be an ID10T.

    I do like your avatar, that is from Kill Bill One, right. That chick definitely got me all "bothered"

    It seems as though everytime someone uses any of the 3 smilies (Search, Google, RTFM) even after explaining the answers to all the questions at the top of their post, the get flamed and told never to use those smilies (and they arn't even thanked for providing the answers anyway)! Get over it! Noobs come here thinking this is a low traffic board and they have some new ideas. I was happy to learn early about the wealth of information that is avaiable when using !
