  • opus 150w Shutdown Timer delay error / Firmware Flash

    I have an old opus 150, It works great, except the shutdown controller timers and not behaving properly.

    This is a copy/paste from the owners manual
    4 3 2 1 JU1
    o o o o No jumpers installed: 10 sec turn off delay (jumpers are inserted in vertical park position- Factory default)
    o o o-o Pins 1 & 2 shorted: 20 minutes turn off delay
    o-o o o Pins 3 & 4 shorted: 40 minutes turn off delay
    o-o o-o Pins 1 & 2, 3 & 4 shorted: 60 minutes turn off delay

    When I have no jumpers installed it still has a 20 minute turn off delay.

    All other configurations behave as expected

    Opus solutions tell me that this device is out of warranty, and therefore only fixable at my own cost. (It has behaved this way for as long as I have had it, I just didn't realize it)

    Anyway I am looking to fix it myself, but I am unsure of what tools i need to flash the firmware or examine the firmware code

    Could one of the resident experts point me in the right direction to get this started?
