    Multi Mode Timer

    Ok I gave that a try but still could get any action I then soldered the coin mech output (pulse) straight to the IC terminal 6. (OPTO1 connects to ) It now works no with no hick up Is this safe or will I damage something in time?

    Thanks for your help colin55 So it should work then

    Connected to O volt rail The shorter lead on the LED is to connected to the O volt rail The longer lead ion the LED is connected to the coin mech pulse Yes LED flashes twice

    LED just flashes on and then off and then on again and then back off

    LED connected from 5volt Dc rail on coin mech terminal (negative) , other end of LED in series with pot which I set as close as possible to 490 ohms then connected to coin mech pluse.

    Yes can program it to do that no problem?

    Ok LED just flashes very quickly once when the coin is inserted.

    Can accept multiple coins , but it is just programmed up for 1 x $1

    It's a coin mech fully programable by PC , these one is used in high end coffee machines It programmed up for $1.00 coin at the moment Ok will give the LED a try and let you know the outcome

    Multi Mode Timer

    I have finally had a chance to give the timer kit a try on a coin mech I have tried changing R1 to a 390 ohm resistor and a 300 ohm resistor but it doesn't seem to work. I have measured the coin output pluse and it has a normal voltage of 2.2 volts and when a coin enters the coin...

    Bonuk You obviously haven't read the last couple of posts . When I was referring to the relay or transistor output we were discussing the coin mechanism in an arcade machine, not the timer. Read the last couple of posts carefully before you post.

    Multi Mode Timer

    It’s definitely not a relay output, so I guess it must be a transistor output then. Is there anyway to tell if i dont have the cct diagrams? So if we look at Boncuk’s post if I use something just a little bigger than 680 ohms it should hopefully work. Boncuks thanks for the info , i...

    I saw the 6v as a min! So I definitely need to change the resistor. It is 5VDC driven from a source, I have no idea what the current would be but it will be very small at a guess 100ma at the max. It’s just a Pulse & it is coming from an arcade gaming machine coin mechanism.

    Multi Mode Timer

    Ok Great thanks Colin Has anyone had any experience with this timer kit? From my understanding of the timer modes, Mode 2 will work for my project however does anyone know when the trigger is reapplied whilst the timing cycle has already started the timer will reset to zero but does it...

    Multi Mode Timer

    Thanks for your replies I am a little confused so will an 800 ohm resistor do the trick? Or from Collins post can it be triggered with 5volts without changing any components?
