(SOLVED) SR5 coin mech help

[PanicAcid]

Afternoon all,

I'm so so so so so sorry that my first post here is asking for help, I genuinely do not enjoy signing up to a forum and having my first post be a question but needs must - please forgive me.

Right, I've built myself a cabinet which is going to have a Windows based AMD AM1 ITX system powering it, I've got the I-Pac 2 setup with P1 and P2 controls and I also have two coin mechs mounted either side of the screen, intended for the use of P1 and P2 credits.

The coin mechs that I'm using are Moneycontrols SR5's also known as C435/C435A's I believe (don't quote me on that though, but the two look identical).

I've found some software designed for video juke boxes that will allow me to hook up one of the SR5's using a serial to USB adaptor, but only one instance of the software can be ran at once and it can only manage one serial port at once so that means I can't hook up both using this solution.

Speaking to some other people interested in our little hobby they have suggested that signal wire can be dropped from 12v to 5v and hooked up to the I-Pac however all of the guides that I have read are built around similar coin mechs, the main difference been that the ones used in the guide had Credit Boards built into them, however the SR5 doesn't I don't think (again don't quote me on this I'm no expert, I didn't even know what a coin mech was two weeks ago).

So basically I'm here to say I'm an idiot, who got 2 coin mechs and built them into his cabinet but now can't figure out how to make them work as intended.

Can you guys help?

If it helps, the manual for the SR5 can be found here: http://www.gmmpro.ru/pub/SR5_Technical_Manual.pdf

EDIT:

Right ok so I think I've come to the conclusion that I need a credit board, one per SR5, I've found a guy who can provide me with two Klingon credit boards, but again I'm at a loss on how I'd hook these up to the I-Pac.

[PanicAcid]

BUMP: Righty I've gone out and got myself a Klingon Plus the board fits onto the SR5 and it inhibits coins correctly (coins are accepted not rejected as they are if you were to just power the SR5)

So all I need to know now is how to correctly wire the Klingon to the I-Pac.

I tried connecting SW1 on the Klingon to Coin 1 on the I-Pac ( as the Klingon outputs 5v) and the O on the Klingon to the ground on the I-Pac however when pressing the service button and deploying credits I'm getting nothing. There's also a O/P1 on the Klingon which I tried using as the ground but again no dice.

Can anybody point me in the right direction with this?

Ok guys so I managed to figure this out after some experimenting.

The Klingon slots onto the SR5 (the rear of the Klingons have a female header which slots onto the SR5 the pin-outs are like so

SR5 Parallel Pins           -           Klingon Validator A Pins

             1                                                     X

             3                                                     1
             4                                                     2
          *KEY*                                            *KEY*
             6                                                     4
             7                                                     5
             8                                                     6
             9                                                     7
            10                                                    8
            11                                                    9
            12                                                   10
            13                                                   11
            14                                                   12
            15                                                   13
            16                                                   14
            17                                                   15
            18                                                    X
            19                                                    X
            20                                                    X
            21                                                    X


I hope that helps anybody wanting to fit a SR5 coin mech or who is wondering if there's anyway to interface the Klingon or the Klingon Plus etc, (probably even Excel boards as I believe they're a copy) with their Moneycontrols SR5.

The confusing thing is the SR5 has 21 pin parallel interface whereas the older C2XX coin mechs that most people use here in the UK with the Klingons are 15 pin like the Klingon themselves, luckily I had a random stab in the dark at fitting it with the Key's lining up and hey presto it worked.


Then all I did to get it interfacing with the I-Pac2 (I didn't use a Zener as I was told that the Klingon outputs 5volts standard on the pulse line for coin acceptance. I'll measure it today with my multimeter and test but last night I went on blind faith.

Working from top to bottom on the pin outs I have it configured as follows


SW1   -   X
SW2   -   X
0V      -   X
0/P2   - Coin 2 (Player 2 Coin Input) on the I-Pac - Note this will only pulse to Coin 2 if you have a second coin mech fitted to the Validator <B> headers!
LAMP  -  X
12v    -  X
MET   -  X
12v   -  X
0/P1  -  Coin 1 (Player 1 Coin Input) on the I-Pac
0V     - PC PSU Ground (Black)
12v   - PC PSU +12v (Yellow)


You'll note that I don't have the Klingon connected to the I-Pac's ground, this is because when I did I would sometimes get misfires or no response form coin drops at all, however as soon as I cut the ground it started performing perfectly. I'll leave that up to further testing and you guys to figure out for yourselves.

for future reference, if you want 2 coin acceptor lines on 1 coin input, you can wire the appropriate lines together (with a blocking diode to isolate them just to be sure)

the coin acceptor coin line basically completes a path to ground when a coin is inserted. the encoder/gameboard/etc senses the path to ground and does it's thing. you can use this way of operation to operate a relay/a light/an LED by simply feeding power into your device (relay/light/LED) and attaching the other lead to the coin line. when that coin is inserted the device will operate temporarily.

I use this mode of operation with some test equipment I made. I have 6 LED's being fed 12 volts DC, when a coin is inserted a particular LED lights up, depending which one lights is the coin line that is programmed to it. I've also powered relays to switch on high current loads like motors and other relays to get equipment started.

the 111/SR5/330/435 with the 15/21 pin configuration are all basically the same. They weren't terribly popular outside of europe. (opting mainly for the 10 pin parallel connection in north america (2x5) as opposed to the 15/21 pin configuration ) the only difference between the 15 and 21 pin configurations is the  individual coin inhibit on the 21 pin configuration, as opposed to an all/none setup on the 15. the 15/21 connectors are interchangeable as you've found out.

Due to the unpopularity of the 15/21 pin connection in north america, this is probably why you didn't get a lot of response from your post. Sorry.

Hey don't apologise, it's not your fault ha ha.

I was testing the coin mech itself with a 12v LED and was getting it to light the LED when coins were going through. The only problem with the idea of hooking a zener diode up from that is each coin only gave one flash, so the I-Pac would be registering each coin as 1 credit, that wasn't what I wanted obviously so that's where the Klingon came into it, multiple pulses based on cost per play and coinage etc.

Under the EEPROM on the Klingon there's a few dip switches, these can be used for games where only a single coin mech is used but multiple players can 'claim' that credit. I believe this is somewhat like what you're describing by connecting the wires.

I'm still not sure why the I-Pac is working without the Klingon connected to its ground :-/

Oh well, my GPIO ribbon cable turned up today so I'm going to be hooking up both coin mechs to the Klingon tonight.

Once I've got the build done I'll get some pictures up here of the coin mech / I-Pac setup for anybody else on myside of the pond who get stuck with such a combination in future.
