  • can manually trip carPC but ignition wont trip

    i have a carPC:
    Via epia m10000
    512mb
    200gb
    OPUS 120
    Touch screen

    the problem is that after hooking up all the wires, i can manually short the jumpers on the mother board to turn the computer on. when i put the wire that goes on to motherboard jumpers to OPUS, it doesnt start from the ignition. i have waited 10 seconds and sometimes even minutes. please help.

    Try reversing the power cable on the motherboard. My OPUS did not follow standard placement and I had to reverse it for the system to start it.

      yeha ive tried that...im thinking that it could be the following:
      1. the signal from the ignintion is not coming becasue through the PS
      2. the jumpers on the PS are messed up
      3. something wrong with the wires from the ignition(ive tried 2 different wires with different guages)

        i'm having the same problem with my 150. It blinks twice every 10 seconds (a boot error). Except i can't even manually trip it to come on. I can't believe what a pain in the *** this turned out to be. i'd rather use my ****ty inverter and save 170$

          Try unpluggin everything piece by piece and see if that helps...like optical unit, video if you can, screen...in your case it's most likely a power issue.

            i sure hope so. I can ditch the 5.25" DvD-RW/CDRW if i have too. And i do have about 4 PCI cards plugged in >_<;

              Dude, I read your posts, and as I read them one by one I find more stuff plugged into your pc...It's a 150W PSU with 90% efficiency, not Enterprise...

                  Also be sure that you indeed wired the ignition line to the ignition feed and not to the power feed. If they are switched, the OPUS will be getting power only when the ignition is switched, but it will never trigger because it is always seeing the signal to turn on/off. If there is no change (i.e. power/no power) to the ignition feed on the opus, it will not turn itself on and off.

                    you know, if he can't get the opus to power it on, it's probably not going to power it off either... so if he does it that way, he's probably going to end up cutting power hard every time... which is not really a good solution.

                    sometimes getting stuff to work the way it's supposed to is a better idea than ghetto-rigging it to work in whatever way possible... but I guess if he's real lazy then it's a possibility...
                    But don't take it from me! here's a quote from a real, live newbie:

                      lol

                      the way i said is the way it supposed to be done
                      its in the directions that are supposed to come with it.

                        That may be there as a backup measure, but certainly isn't what is supposed to be used to start the machine on a regular basis. If the PSU is not shutting down the OS (which is likely the case if it isn't starting it up either), this will necessitate doing that manually with your suggestion. I guess technically it does not require it, but most people prefer clean shutdowns and files that are intact when they start back up.

                          this is the way it works:

                          Your computer is on you turn your key to off

                          opus senses that and sends the pulse to the motherboard
                          computer shuts down

                          after a little while the opus powers off other than the 5v rail ( in some cases)

                          then you turn your car back on
                          the opus senses and gives 12v back to the mobo

                          the mobo senses the the power was lost and is now back so it turns on

                          that is how almost all setups are supposed to wrk

                            Ok, and here is how it is supposed to work

                            Ignition shuts off, OPUS senses power loss on ignition line and waits X period of time to shut down. Computer shuts down and turns OPUS off.

                            Then you turn the car back on, OPUS senses ignition power and sends power on signal to the motherboard through the power or sleep switch jumpers.. Motherboard is told turn on, so it does. Resume after power loss is NOT there as a power on switch. That is the **** poor method to turn a computer on in this environment.
