    Change the jumpers on OPUS 150 while it's on?

    Is it safe to wire up a switch that would allow me to change the delay time jumpers from 10 seconds to 40 mintues while the OPUS 150 is on?

    good question I always planned on trying this but never got around to it... I doubt it would hurt anything...

    well, I was going to ask the same question on the M1-ATX... I talked to an electronic guru here at the office and he said there is a possibility that the circuit could poll the header at boot and the shutdown according to that... so changing the jumper while it is running might not make a difference... so tonight I intend to just give it a shot, cause I want to have mine setup so that it will shutdown with the key or stay on indefinitely (at gas station or sync'ing files at the house)... or I can switch between shutdown with key and 30mins...

    will try to post finding tomorrow...

    Yes you can - Ive just finished writing a modding guide on how to make a lead for doing this but I cant work out which forum to post it in.

    It could go here, or in hardware development, or in the FAQ section... suggestions on a postcard please for now you can read it here http://www.digital-car.co.uk/forum/viewtopic.php?t=1476 till I figure out where best to post it.

    hey mad ad great discription, but there are no pictures at that link for some reason, this should definately be posted here, I would think in power supplies with heading "opus timing mod.s" or something like that...

    I always ment to play with this, but I also thought of just using some sort of a variable timer to keep the ign feed alive to the opus alive for as long as I would set it for... that would give a wider range of control & go beyond the 4 set times of opus... could even set it for 2 hours or more... then when the timer trips opus could shut down 20 sec. later... I have so much other stuff to finish though & this is more fine tuning than critical for me at the moment, thanks for the info.

    Its possible on the Carnetix range, already done it here with no adverse effects. Even Mike said it was innovative.

    Thanks rick/turbocad6 ..... yeah perhaps power would be the right place, just itll probably sink like a stone after a couple of days- itll still be searchable I guess.

    Not sure why you dont see the pictures, its on my ISP webspace, national company, 50 megs no b/w restrictions etc (but they dont dont know their backside from their ear sometimes).

    Its only the pic of the rotary thats important, beats my long explanation of the connections anyway

    i did it a different way
    i put an on-off-on switch in the dash

    i now have these options,
    1. ignition mode...i.e. boots on ignition and shuts down on ignition

    2. completely off...OPUS power supply gets no ignition signal so doesn't boot at all (can also be used to manually turn on and off PC while ignition on, like for testing)

    3. always on...i.e. for those times you wanna leave it running while you pay for petrol (gas) and stuff
