How to send credit to a S+ machine only with pulses

[ersk3]

PSR still needed for SP1168 per this post
http://newlifegames.com/nlg/index.php?topic=15014.0

I am glad to share this news with you. As I have discovered it is possible to send credits into a S+ machine only with pulses.  You will need one of two game chips: SP585 or SP1168. Both game chips have this feature, and are the only ones as far as I know. The main difference is that using SP585, you are able to cash out the credits you send in with pulses, but using SP1168 you have to play the credits (you are only able to cash out winnings). Hope you find this information usefull

At the connector locaded in the main door, you will have to send in 50ms pulses between the purple and the green wire.



The purple wire connects to the main board at P1.12A. The green wire is COM.

You've got my curiosity. Post a video showing what your doing. I'm confused.

Jim, I have made a video for you, hope I don't make you more confused. I'm using a standard puls generator, sending pulses on 50ms to a IGT s+ machine, wired as descibed in my first post. As you can se, the credits increase according to the pulses sendt in to the system. What do you think? Erik

Nice.

Wondering what would be necessary to make up a circuit of some kind to have it send the pulse by pushing a button. 

[rokgpsman]

Looks like the pulses are imitating the signal that would be sent from the casino server to add credits, like if a player inserted their players card and had some type on bonus bucks or something on their account. You know, when the little "$" button lights up, you press it and you enter your pin. Then the menu on the player tracking panel lets you download money or credits to the machine you are playing. Is that the comm channel that is being used?

Odd that this feature is only on a few SP chips, maybe it was eliminated or changed on later chips?

ersk3 - where does that connector with the purple and green and red wires normally get connected in the machine, like if it was in a casino?

[ersk3]

rickhunter - It wouldn't be too difficult to make a circuit to do so, or simply use a microcontroller with some simple code to do the job.


rokgpsman - The casino that had these slot machines used a interface board to connect the IGT s+ slots to external note readers and electronic coin acceptors. The reason for this is because of the problem when casino machines are placed on ferries between borders, with different currency.

Very interesting project, and excellent documentation by you.   

What I was wondering about is the original IGT purpose of that connector with the purple, green and red wires near the door? Did IGT have it connected to anything, or was that connector installed at a later time on the ferry? Since those two SP chips have this ability then IGT would have needed to add the wiring for it to happen, yes? Maybe those 2 SP chips were created for this type of situation on a request to IGT by their customers?

Also, are you sending random or repetitive pulses into the machine and the credits continually get added or is there a set number of pulses (codes) for different amounts of credits?
 
I saw on the other thread that you received the psr for SP585, does it document and give details on this feature?

rickhunter- does the psr or other document for those two SP's talk about this feature to send in credits to the machine? And don't most machines in the casino have the ability to download credits from the slot club reward promotions? Is this the same sort of thing?

[ersk3]

I do not know the original purpose of the connector from IGT, maybe you can make something out of the connector diagram in my first post? Does "I.R DET M+ SER / CHG S+" mean anything to you?  I have seen this connector in all s + slots I've owned, not only those from that casino. It's often hidden away behind the harnesses, but is always there (take a look in your own s + slot and check for yourself). I believe the two SP chips where created by IGT for this single purpose, requested by the costumer.


The pulses is sent randomly into the machine, no codes needed. Simply, one pulse equals one credit. The pulses need to be 50ms + - about 10ms to be registered as a credit.


I only have the psr for the SP585 chip and it's not mentioning this feature. I am still looking for the SP1168 PSR (please pm me if you have this PSR). The system is a stand alone system and is only communicating with the note reader and coin acceptor.

[ersk3]

rockgpsman - I read through the PSR again for the SP585, and it actually mentions the external NRI coin acceptor, but only in one sentence.

I can't decipher all of those IGT mnemonics for motherboard plug 1 pin 12. "DET" could be Detect, "Ser" could be Serial or Service. The only thing "I.R." brings to mind is Infrared, but that doesn't seem right. 

I don't have psr for SP1168, sorry. Also, I don't have an S+ machine here. But if that connector is present on all or most S+ machines it would seem that they planned that it might be connected to something in many of the machines, makes me think it is for an optional but popular use if they went to the trouble and cost to add it when built. Perhaps this connector is only on S+ machines specifically ordered with it, maybe just for special uses like your ferry boats? If those two sp's chip are the only ones that use that connector pulse input why put that connector on machines that got other sp chips at the factory? How do we know that sp585 and sp1168 are the only chips that allow this type of pulse input to add credits? So this connector with the purple, green and red wires connects to the interface board for those note readers in the slot stand in your photo of the ferry machines?

This is a nice discovery, gives an easy way for someone to add credits to their home machine. A small board can be built that has a circuit that continuously makes those 50 msec pulses, and a pushbutton or momentary switch connected to the output of that small board can be closed (switched ON) to send those pulses over the purple wire to pin 12 of that plug 1 until the desired number of credits have been added. Is there a limit to how many credits can be added, is it limited by another setting in the S+ preferences/settings menu?

Still much to think about.

I think we can say that the two SP chips you have there add credits as you described, but do we know for sure that only those two SP chips offer that function?

[ersk3]

rokgpsman, knagl - We do not know for sure that it's the only two SP chips that offer this function, I am just assuming that. I have tested on a handfull other SP chips, and the ones I have don't have this function (example SP584 that was the closest one I had). I did a hex compare between SP585 and SP584, not much where the same in the code. I also did a hex compare between SP1168 and SP585, but I couldn't tell where in the code this function is implemented.


rokgpsman - Yes, every one of those machines in the photo has this board mounted. When I used SP585, the credits accumulated over a 1000. When I used SP1168, credits wouldn't pass 999 (all winnings over this was instantly payed by the hopper). Since I don't have the PSR for 1168, I could not tell if there is a setting for this in the menu.

[knagl]

rockgpsman - I read through the PSR again for the SP585, and it actually mentions the external NRI coin acceptor, but only in one sentence.

I found another mention of it in the PSR:

only the Montana–style credit is compatible with the external coins acceptor (NRI).

This actually makes sense to me.  With Montana-style credits, you can keep adding coins to the credit meter without wagering them.  With an external coin acceptor, there would be no way for the machine to "lock out" extra coins like it can with the built-in coin acceptor.

[rokgpsman]

So any SP chip that allows the Montana-style credit feature could also possibly let credits be added the way ersk3 has discovered, maybe?

Never used this SP so I am not sure of the settings. In section 7 .. if there is a <7> [3] (max credit limit) then verify if the setting is causing the 999 limit. This limit causes the coins to be dispensed as you describe.

May or may not be the issue but just throwing something out there.

[rickhunter]

Because he is adding credits through pulses, it's basically emulating coin ins.  I would say that any montana style credit chip would work as it is the only type of chip that will allow you to insert coins until you reach the credit limit.

[rokgpsman]

The "Montana credits" thing is called that because the gaming commission there requires/allows it, something unique that no other jurisdiction has?


 

[rickhunter]

I don't really know the origins, they are also known as euro style credits.  These are also the chips that can be used to assign a token value.  So you can put say a quarter and have the machine give you up to 99 credits.
