    Talking OPUS peoblem SOLVED!! read me

    alright guys, i decided to create a new thread cuz it applies to more than just me. as u know from the other threads i was having a problem getting the opus to get the computer to post. it would boot, spin the drives but would not post. today i decided to pay a visit to opus (80 miles from me) and heres what i found out:

    both the OPUS and the mobo were fine, but what i was doing was connecting the 2 yellow and 1 red together for testing. and then i also ran it in AT mode (with pin 1 and 2 jumpered on J6). well the solution is as simple as this:

    ralph the opus tech said it happens all the time:

    DO NOT CONNECT THE RED WIRE UNTIL THE FIRST BLINK OF THE OPUS. i dont know why, i dont care why, but unjumper J6 and only give +12v to the red wire AFTER the first blink.

    its been running for an hour now, no problems. actually im getting the system to how i want it right now. 7" screen is NICE but a wee bit small on the system fonts. ah well ill get used to it.

    HTH someone..

    btw the powermate kicks ***...haha

    What red wire are you talking about? There's about 7 on the Opus . I just wired everything up and the opus blinks once every like 30 seconds, when i turn the key it blinks twice every 10 seconds. I have all the wires plugged to the right places. I took the opus out and put a regular AC-DC PSU with an inverter and the computer booted up fine, so it's not the computer thats messed up. I also checked in the BIOS but did not find a single setting that would change anything to make the OPUS boot the damn PC >_<;

    What happens when yoiu push the power button manually? does it refuse to startup???

    You must discover if it is the SDC that is misbehaving somehow, or if it is the power supply that isnt managing to power the computer.

    did you try reversing the power-on pins? if you get them the wrong way around then the mobo wont power...

    Cool A lazy nub

    Hi people,
    I'm so noobie at this, I don't even know how to post my own thread.
    So, I'm one of those impulsive buyers that likes an idea and go off and buy stuff. Everyone in here so far, seems to have problems with their carpc. Has anyone ever have their carpc set up and running smoothly?

    Call me lazy, and make all your comments and remarks about doing research and knowing what to ask, but I got confused at a lot of the thread with all these people and their theories.

    Here's my situation, I got the lilliput screen (finanlly got the touchscreen to work), the HP e-vectra which has a laptop like power connecter (19V i think) and the gps installed and working. Stupid computer only has 5 GB left on the Hard drive. Wil probably buy 100GB external.

    Everything good so far, but to the main problem and the confusions. This computer has no PCI slots and I dont know how to get into the computer. that means I can't install one of those mAtX1 auto power thing.

    Can the experts with actual carpc working give advices please.
    Something to convert voltage of the computer, auto start and shutoff. I think thats about it. Another thing, how do i play the ipod without having it downloaded to my computer. I will also put in the PS2 since i dont use that anymore. And a rear view camera. etc etc, first things first. How to power this thing, I know there's a simple answer and theres an expert out there who can help.

    Thanks so much for reading guys.
    Hopefully I can run around town and showoff to the world soon

    I don't understand how i can push the power button when it's connector is unplugged to make way for the PSU's power switch connector. So no the power button won't work. I've even removed the Opus's power connector and plugged the power connector in and the switch didn't make it turn on either.

    What do you mean by reversing the power-on pins? I never thought the power and reset switch's polarilty mattered. And which way do i reverse it? Do i reverse the whole cable itself? The mobo end to the PSU and the PSU end to the mobo? Do i just flip the PSU end? I don't really get this

    Also, i have my 3 wires wired as followed:

    red to constant 12v @ ignition harness
    yellow to the Accessory wire @ the ignition harness
    black to ground

    I tested the connectors with a multimeter and the red is always 12v with or without the key in. The yellow is only 12 with the key in.

    After reading the Opus instructions i noticed it said the yellow was an "ignition" wire. So i figured i had to tie into the Starter (ignition) wire instead of an always on ACC wire (when key is in it's always on).

    I tested the starter wire and it showed 12v when the car was turned on, then it went off. I tied the yellow into this wire and the PSU still didn't turn on. I'm amazed

    Is the e-vectra known to work (or known not to work) with the opus? (search if you havent yet... there might be some known issue)...

    about reversing the pin, the power-on does have a "right way"... not turning the whole wire around, but basically turning the mobo connector the other way:

    : top=green bottom=white / switch around - : top=white bot=green
    get it?

    but if you tried with your power button and it didnt work then that isnt the case!

    Yellow should be 12v when car is on. ignition=acc in this case.
    There is a post that says you must connect the yellow wire FIRST then the red wire.... (first post in this threwad)

    You can splice a button in parallel with the green/white wires that go from the MOBO headers to the PSU. Thats what I've done, and it works like a peach.

    As for reversing the wires, definetly try it. That was one of the big things that was wrong when I was setting my OPUS up.


    As far as people trying to read their flash codes, here's a excerpt from the OPUS 150 users manual. You can also d/l a copy of the manual Here
    0.1 sec ON and 2.5 Sec OFF:
    DC-DC power supply is in Idle or stand-by state.

    On constantly:
    The PC is powered and the PC should be operating.
    Number of flashes Reason for flashing

    1 Flash:
    Battery voltage is below normal operating range.
    The normal range is 11.5 VDC to 18 VDC.
    During engine cranking the low battery voltage detection is ignored so the battery voltage can dip below 11.5V.

    2 Flashes:
    The computer power up sequence failed
    Reasons:
    1. Check the wiring of the two wire power-switch cable from power supply connector J9 to power switch pins on the ATX motherboard. If connected properly check the polarity of the power switch pins. May be reversed.
    2. Check ATX mother board bios settings.
    3. Locked up mother board or software crash of bug.
    4. Faulty DC-DC power supply.

    3 Flashes:
    Power supply output voltages are out of normal voltage range.
    Reasons:
    1. Power supply output is over loaded or shorted.
    2. Faulty DC-DC power supply.

    4 Flashes:
    Power down, stand-by or hibernate sequence failed.
    Reasons:
    1. Check the wiring of the two wire power-switch cable from power supply connector J9 to power switch pins on the ATX motherboard. If connected properly check the polarity of the power switch pins. May be reversed.
    2. Check ATX mother board bios settings.
    3. Check if ACPI function is enabled in the power management BIOS setup.
    4. Make sure ACPI drivers are installed in the operating system.
    5. Check if application is compatible with ACPI mode of operation.
    6. Locked up mother board or software crash of bug.
    7. Faulty DC-DC power supply
    When we're talking about the red wire we're refering to the one on the harness that connects to the car itself. The one with three wires on it. Red, Yellow, and Black.

    And as for the comment about does anyone have theirs up and running, a lot of us do and are very happy with our systems. Since these are not simple plug and play systems, they take a lot of planning, a lot of working out on paper, and a lot of troubleshooting. Most of the problems can be avoided by pre-installation planning and troubleshooting. So take your time, do your homework, and don't rush into things, and you'll find that you too can have a systems thats running well.
