How to enable coin mech?
« on: November 13, 2016, 08:50:24 pm »
I bought a cocktail arcade from Craigslist running a 60 in 1 board, any idea how I can enable the coin mech?

I notice that you have the machine off when you inserted the coin.

Some acceptors will not accept COIN when machine is off (due to the lock out coil unit and it looks like you have it).

if you lift up the part of the mechanism that has the big QC control sticker on it, you can insert a coin under the backside what which you would like to accept.

then the mechanism will work for the coin of that type.


for the 60-in-1 board... you should have a test and service switch someplace either inside the door there or...somewhere. whever the person who made it... put it.

press and hold one of the buttons and apply power to the machine... this will boot it into either enter the test or service mode. in this mode there are some virtual dip switches to enable or disable the freeplay and also how many coins you need to enter to begin a game.

you will probably want the first bank row all "off" this enables 1 coin per play.

and the second row set to "on on off on off off off" this will disable freeplay and properly set your machine to cocktail mode.

(the music is annoying trust me) but if you like it the way it is and just want the freeplay disabled, set bank 2 dip switch 3 to off

I removed the part, opened it, but I saw no place to put a quarter. 2ndly I tried loosening the screw, but it still rejects the coin. I also tried with the machine on, but nothing

And the wires go to the chassis of the monitor?
The 60 in 1 should have a cable to to coin mech.

And is has to be turned on, if the machine is turned off, it will never accept coins.

http://www.ultimarc.com/controldiags.html (bttom of the page) has a little explanation

Looks to be one of this kind of mech - the coin is placed inside where this pic shows the yellow label - lift and place a coin of the type the mech should accept and it should then accept that type/size of coin.

yes, the coin you want to accept goes in the outermost slot (colored gray). this appropriately sizes the inner slot (colored yellow) to properly accept the coin size matched. the spring holds the coin in place. just lift, insert the coin from the side and allow the spring to pull the mechanism down and hold it in place.

just rolling through is good. that means it's sizing properly.

there is a trim pot that will allow for better acceptance. turn it more clockwise for better acceptance.

also be sure you aren't using an odd coin. (like a special issue or a particularly new coin (as old coins may not work) or a particularly old coin (as newer coins may not work))

the mechanism compares the metal composition to the "test" coin. if it's close enough... it will accept.

I'm using  1997 non special quarter. I also tried a 1970s quarter. Both reject the coin. I can't locate the "trim pot", here are some photos of the device.

Random question , could it possibly be rejecting coins because the 60 in 1 is set to free play mode? Edit: I switched free play off, still rejects quarters.

I turned it all the way clockwise (slack) and it still rejects the coin. For good measure I turned it all the way counterclockwise and it does the same

ok follow the wires back
u should have 12 volts dc on the red wire
the white wire should be coin pulse out
the black wire should be ground
again it must be 12 volts between the red and black wire

I can understand that the machine can't add a credit without power, but would power supply have anything to do with a coin falling through or not?

Yes, if its a electrical mech it will need the power on to compare the coin.
Otherwise it will just reject it.

this style of mechanism is designed to reject everything regardless. even with no power or defect.

you put the coin in... it starts rolling down the chute.... when it passes by its sensors it compares it to the test coin. if it doesn't match... it does nothing. the coin continues down the chute and out the front. but if it does match, a solenoid activates ... a trap toor is opened part way down the chute and the coin falls out of the acceptor and into the machines coin box. once the coin has cleared the acceptor (has a sensor on the way out) it issues the pulse that tells the game a coin has been inserted.

maybe whoever built the machine didn't attach the power to the mechanism. you'll need to check to see if there is 12 volts between the red wire and the black wire on the plug attached to the acceptor.

There are 3 wires going out from the coin mech (red, white, black), as far as I can follow, they're hooked up to the 60 in 1 Jamma board. Would that power the coin mech?

the red wire must be tied to 12 volts dc
the black wire must be tied to ground
the white wire must be tied to coin 1 input on the jamma interface
it is that easy

There is a red wire hooked up to 12v on this thing, I am not sure if it's the one leading to the coin door, then it's hooked up to the switch which powers everything (monitor, jamma, speakers)

I suppose the next step is to trace the exact red wire to make sure it's hooked up to 12v?

that "thing" is called the power supply
and no i see the red on 5 volts
black on ground
orange/white on ground
orange white and  yellow  and orange on 12 volts

it does not look like the coin mech is even wired into it
i would trace the wires from the coin mech backward carefully and see exactley where the red wire ends up
DO NOT FIDDLE WITH THAT "THING" as it powers your 60-1
and u will do dammage in a big way
i wish u had a meter
would make life so easy

I finally traced the wire. It splits into 2 (see first pic) and 1 is connected to ground, the other to 12v.

I added the green circles and the green highlighting. Now what can I do?

It wont split into 2 across 12v and ground, that would be a direct short!

You really need to buy a multi meter.
They are inexpensive and will save all the guesswork and time thus far.

Well shoot. When I get home tonight I'll trace the wire again. I'll buy a meter as well in order to test this.

Quick question, how am I supposed to test the red wire? Wouldn't I have to do this from the end that's plugged into the coin mech (since the other end is supposedly hooked up to the power supply)?

red and black at the plug that plugs in the coin accepter
just un-plug it from the accepter and insert props in the plug end
not the accepter pins but the plug end
turn machine on
u either have 12volts between the red and black or u do not

in this case i think going to the store and buying the cheapest volt meter (even a 12 volt test light would work) and checking for 12 volts at the connector would be super easy.

I've decided to devote the rest of my evening to fixing this once and for all...

Going to walmart to get a meter, I shall report back.
If I get this one, https://www.walmart.com/ip/Digital-Multimeter-10709/14521541 how do I use it? I know nothing about wiring, and am only slightly ashamed to ask such basic questions.

from off
the scale on your left is dc/ac volts
click to 20 that will more then do
do make sure the dispaly reads dc not ac
if u are in that scale and it gives u no sign of dc but if u hit the squilli buttom (it changes it from dc/ac) and it shows
ac just tap it again and u are in dc
black probe is ground (so black wire to the accepter plug)
red wire is + on your meter vma/hf that would be the + input to your meter so red wire to accepter plug
at that time with power on (machine and meter) you should get 12 volts

the unit truly dose not work right under 12volts
its get goofie
i wonder about some thing
go to the power supply
see if this rings out for u

red always go to the + in your case the top screw = red
2 be safe I would say #3 screw down gets the black probe
the reading there should be
+5 volt
the 4th 1 down to the #3 screw should give u 12v - red probe

So with red on screw #1 and black on screw #3, I got between 5.0 and 5.1, which is good. Which are the other 2 screws I'm supposed to measure?

Edit: I uses the red probe on screw #4 (that reads +12V/2A) and the black on still on #3 (ground 2), and I got 11.2v

There's no lights on the cabinet. Only things drawing power are the 60 in 1, speakers, and monitor. And apparently the coin door

Without the jamma board it hovered around 10.65 (???), when I plugged it back in, it went up to around 11.30.

I filmed videos of this, but YouTube is being buggy.

wow
that was taken at the power supply ?
if so get a replacement asap
as either the wireing or the power supply is ground looping

those power supplies usually just regulate the 5 volt and leave the others to float all over hell's half acre...

I would also unplug the coin mech and test the 12 volt line again. maybe the mech is no good. we should power the coin mech from a separate known good 12 volt supply (like a wall wart) and see if it's working first... before we go diving much further into this power supply.

I unplugged the coin mech power supply (meaning the cord hooked up to the coin mech, I didn't mess with the wires coming from the power supply), and (with the jamma board still in) I still got around 11.3

I don't mind buying a 12v power supply just for the coin mech, if that's what I need to fix it.

my main concern is the 12volt rail is low
on a switcher it is usualy the other way around
where the 5volt rail dip out
the 12 are perty robust
in this course of action i would just replace the main switching unit
as i have a bad feeling it is getting ready to puke on u anyway

Okay, can you tell me the name or model # of a unit I can replace it with?

Also, is it as easy as unscrewing each wire and screwing it into the new switcher?

I personally wouldn't discount it quite yet...

a cheapy cheap peter chow type supply often has the 5 volt be the only real regulated supply with the others sort of based off it.

you can test if this is the case by running the 5 volt adjust pot up and down and see if the 12 volt goes up and down too. (disconnected from the board of course.) you can also test this by placing a large load on the 5 volt (I use a couple car tail light bulbs with 2 filiments each and run them both together, it's about a 1.5 amp load)) and see if it brings the 12 volt line up. if it comes up, this is the issue.

Also, quite often the feedback pin for the 5 volt is incorrectly tied to the output of the regulator circuit instead of on the output connector after the  inductor filter like it's spec'd to. not a big deal, but allows a lot of delta in the load before the supply compensates

also, these xxx-in-1 boards are not a real high load like the old boards used to be. this low loading can cause regulation inconsistencies since the supply is being run at a tiny tiny fraction of it's output capability. These supplies probably should have a "minimum load" requirement as well.

back to the task at hand....

these XXX-in-1 boards really don't care if the 12 volt is out a bit, it's just used for the audio amplifier. in fact, the board will run without 12 volts at all (without any sound of course). i'd say for the time being, the existing power supply is passable for now.

the coin mechanism on the other hand is fairly picky about having damn close to 12 volts. if you have a 12 volt DC power supply (if even to borrow from something just to test) and hook up to the coin mech to see if it is even working. I mean who knows, maybe whoever built the cabinet just threw in a random coin mech that he had laying around just to fill the hole. I would think ~11 would be close enough but i've experienced weirder.

if the mech is toast, they are super cheap. you can pick them up on ebay for about 20 bucks shipped from the land of many cheap item shenzhen market super happy best quality S+.

meh, you run what you brung. it's there might as well try and use it.

maybe OP is just looking for more of an authentic experience of dropping the coin and playing a game. But sometimes being able to just adding credits to play a game doesn't encourage you to try and play better... ded...add another credit....ded add another credit. no fun there.

Oh, I'm all for using a coin mech. All the games in my game room I set to use tokens. But I wouldn't use an electronic one. It seems like it's more hassle than it's worth. You could easily spend 20 bucks and just get a 8 liner coin mech does the exact same thing without using electricity.

an 8 liner style mechanical with a microswitch is probably the best most reliable method, and would easily slot in the same area as the current electronic mechanism.

depends on where OP price point is in terms of what's available and how he wants to go about it.

unless i or u ppl missed the point the op is a newbie to electronics and or games
so the easiest path is to get to the "fault" taking out personal prefrence.
lord the op never even owned a meter
but all that aside yes by all means a mech with a switch is better for alot of reasons
i was just not into re-inventing the wheel as it is said

I'm still here, I ordered the coin mech that lilshawn linked. Worst case scenario, it also doesn't work (aka it's the wiring) and I pay return shipping of $3.

Is this the "8 liner style mechanical" coin door you referenced above? https://www.amazon.com/Arcade-Game-mechanical-selector-Jamma/dp/B00F1YQJJ6/ref=sr_1_1?ie=UTF8&qid=1479763184&sr=8-1&keywords=mechanical+coin+door

A little more background, I am 21 (not that it matters) and I own a business; I want to get this accepting quarters so I can put it in my lobby. I already have candy/vending machines so it would be nice to have another thing for my clients kids (and my clients themselves) to enjoy.

I'm definitely a newbie to anything hardware. I've built 2 cabs using Windows/Hyperspin (A cocktail and a full size upright); I purchased this cocktail cab on Craigslist for $600.

it's a simple size/weight scale acceptor. anyhting that is of a similar size and weight to the coin it's designed to take (likely quarter) it will take.

it's lets the game know a coin has been inserted by a mechanical switch.

First, having the correct voltage at the PSU isn't necessarily a good thing - usually it needs to be some % higher since there is always some loss in the cables and connectors before it reaches the actual game board. This varies from one cabinet to another and generally it is a bigger problem the more power consuming the game is (since higher current creates a higher voltage loss over ( U=I*R)).
So for a 60-in-1 board it should be more or less something you could disregard.

One thing you could easily test is to disconnect the PSU and hook up the board with a good standard PC PSU with the molex connector, and then let the coin validator get power "backwards".

Hey guys, I got the new coin mech in & installed it. Simultaneously, the power socket decided to fail (bad soldering), my repairman happened to have some quick connects & wired up the new one. So finally...

...The coin door works!

Thank you all for your help!
