Touch Screen Jukebox project conversion

[lilshawn]

if you are just going to hack a keyboard or number pad, that would be pretty easy. most have 5 volts sent out on all the keys and sense when the 5 volts comes in on a particular line when you push the key to connect the switch. of course you would have to verify with a volt meter to be 100% but chances are that's how it is.

there are some small differences in the credit boards between runs. if you take a nice closeup photo of the front and back of the board, i'll paint on the photos the mods that need to be done for your application. pretty easy stuff. couple of wires. cut some stuff off. no biggie.

Brilliant this will help me out big time

Will take pics in the morning

Sorry took me so long but here is the board, hope these are clear enough

hi
is that red pushbutton not the service credit add button ?

here you go.

the mech acts like a switch. when you insert a coin it connects the input (shown as the orange dot which you will feed your 5 volts from your keyboard interface) to the coin line for that coin.

likewise if you need it to pull the line to ground you could connect it to ground instead of 5 volts. you can get the ground from the extra ground wire...peel it back off the rest of the ribbon and solder it to the point.

again, test your keyboard and find out for sure how it switches. it might be high, it might be low.

yes that was it's original function. only problem with it was.... it just bypassed the mech and triggered the line directly. if you didn't happen to have that coin line programmed for anything in the jukebox, it didn't work.

Excellent, thankyou, will digest this info and look for a suitable keypad

thanks Ronnie

Ok thanks again, when I looked at this last night had had a few beers

Can make more sense of it now, so I need to check how the donor keypad works first high or low input, if it's high feed +5v to the board and for low -5v to the same point

not got the keypad yet but was looking at this one, nice and cheap

might that do the job?

thanks Ronnie

I got the keypad today, opened it up, it's very delicate, do I need to trace the keys I need say 1 2 3 and 4 to the pcb, I think it's ground rather than +5v but not sure?

[Drnick]

In Short Yes,   see the following video for a simple how to.

[ronnie-dent]

This did not work for me! managed to hack the keypad no prob I used botton 1 2 and 3 as they shared a common and my patched in wires when made did activate the keys in notepad

the mech is rejecting everything so it must be the supply to the mech I think?

cheers Ronnie

you should be feeding it 12 volts. either via the regulator (supplied with 13.5-30 volts) or if you bypassed the regulator 12 volts from the power for the computer. You can't supply 12 volts to a 12 volt regulator, it won't work.

if you are powering it with a "wall wart" be sure it's capable of supplying at least 2000ma (they say 2.3 amp asumming original style 111) the unit uses about 400mA when opertaing idle. the newer cashflow 111 uses a little less i think. I'm assuming it's a 111, but there is about 3 or 4 variations of the 111 mech as it was released right as mars was being dissolved and MEI was taking over the manufacture.

check your coin channels to make sure they aren't disabled. they should be all connected.

try old coins. they sometimes change coins metal content or weight. your old mech might not read newer coins that have higher tolerances during manufacture. Thickness and weight can vary wildly.

electronic mechs can be finicky. there could be something wrong with the mech as well. which mech is this? the newer style 111 has a diagnostic light on it that shows the status. it flashes appropriately depending if the coin is bad rejected or disabled etc.

Thanks for the info, the mech is a cashflow 330, I cut the regulator off and patched as per your sketch, I'm using 12volts fed from an xbox360 brick which is 16amp but it is also running the lcd screen and led lighting, as far as I can see the mech has no led on it.

hi
cashflow 330's come in a few way's
1 is a 10 pin header on the side
1 is a 17 pin header on the side at the bottom
which ever 1 u have make sure that the inhibit line's are tied to ground
if u need a pinout for the 17 pin job or the 10 pin job
i can post it for u
on a side note here i have never seen a cashflow 330 in a nsm
that's a new 1 on me,as nsm used there own coin accepter
but hey i have been wrong before

yes, the early 330's had the flat 16 pin flat connector and the newer style 10 pin (2 rows of 5 pins (DIL)

on a side note here i have never seen a cashflow 330 in a nsm
that's a new 1 on me,as nsm used there own coin accepter
but hey i have been wrong before

yeah they changed to a 3 1/2 inch acceptor in the last few models they put out (most ES-V and later...about 95 or 96 they changed). which is good since many of the 5 inch channel types are dying out.

the 330 is still supported by MEI and most vendors...so if it is broke, it should be easy enough to find someone to fix it. "team one repair" and "betson" are the authorized repair depots for the US. We send our MEI stuff to arbortronics for repair cause we're in Canada.

which ever 1 u have make sure that the inhibit line's are tied to ground

all your lines should already be tied to ground to accept the coins (the green jumpers i marked on the right side by the big cable)... these tie the inhibit lines to ground...cutting the jumpers inhibits the coins.

make sure your ground from the xbox supply and the ground of the computer are tied together. if they arent sharing a common ground all kinds of wierdness can result.

other than being toasted, the only other thing i can think may have happened is the coin programming has been corrupted resulting in all coins being rejected. It's not uncommon and not unheard of.

hi
ya i just got my zaper last week from them
and am now using mei in my touchtunes
>arbortronics <,and thk-u for the head's up on the converision that nsm did
.....
and yes u are 100% correct about
>other than being toasted, the only other thing i can think may have happened is the coin programming has been corrupted resulting in all coins being rejected. It's not uncommon and not unheard of.<

and yes make sure :ALL GROUND'S ARE COMMON:

ed

[ronnie-dent]

Thanks guys, I'm a bit confused on the common grounds! I think the method from the keypad is a switch matrix so the 4 keys I have used share the same common, but would that be ground? have not tied ground from the pc, should I take a ground from the usb on the keypad, I thought as long as the mech has it's 12v it should read and accept coins?
