S 2000 ???????????????????????

[TZtech]

Hi

The S2000/IGame platform is a bit different form the PE+/S+ platform. It has only the two optics on the optic board. The third pulse has to come from the comparator. If you go into IO test you can check if the status is changing on all 3 the inputs. My guess is that its nnot getting the expected pulse from the comp and then Optic A and Optic B. If it does not get initial comp pulse but A and B optic pulse it tilts.

Edit - Some info from some checks I did a while back- S2000 would be the same thing

Ok so I have been checking the I-Game platform. Works a bit different from the PE+/S+. for starters the coin comp does not trigger the optic board but status is reported to the processor.
The two optics are normally high and go low when a coin passes (And to detect when board is disconnected). The coin pulse signal is normally low and goes high on coin detect.

So the sequence will probably look like this 3= Coin In Sense. 1 = Coin In 1 2= Coin in 2
3 1 2

0 1 1
1 1 1
0 1 1
0 0 1
0 0 0
0 1 0
0 1 1

Buzz,
  the post was to show that you were using the correct clear and key chips with the 224 and 31, so they can be ruled out.  Is it the same comparitor from the working machine.  I was thinking the same as TZ when I asked coin size, it seems as if the machine doesn't like the signal or isn't able to accept it.  Comparitor or some conflicting settings which you said  you ruled out.

Agree with Wayne. Dont think this is a setup issue. Have been thinking some more about this. Did these machines by any chance come from a TITO casino ? Did they ever work on coins that you are aware of?

Normally to make a machine coinless you will add a plug with jumpers at the connector where the coin assembly harness plugs in. All this does it keep the A optic and B optic IO's in a permanent Hiigh logic level. Now it may be possible that this mod was done on these machines by lazy techs somewhere further down in the harness. This could also explain the tilt Ie it gets the comp pulse but never the A and B optic pulse.

Either way do the IO test for each IO and see if it pulses.

Ian   I could never find the I//O optic test you are referring to.
  But I did get three of the machines to take coins, the fourth one I have to wait until dark to work on it. I wouldn't want anyone to see me working on that BUTT UGLY S 2000 9 line in the day light. Now your asking how I got them to work, and I really don't know. With a multi-meter I traced the wires from the coin optics back to the door I/O and they were good, so while I had the I/O out I sprayed electrical cleaner on all the connections. Put it back together and couldn't get the coin in error to clear, after messing with the door optics (nothing wrong with them) I took a small pick and bent the female connectors that go from the coin optics to the door harness, That did the trick, worked so good I did the same steps on the other two machines. I should add I did not do another clear or Key today, 


Jim, Wayne and Ian   THANKS

excellent Buzz.  and you didn't have to shoot them...

thanks,

Good job Buzz! 

So it sounds like you had dirty or bad connections in each of the female plugs on the end of the harnesses that connect to the optics. With this happening in so many machines, could this be another common weak point in the S2000 that people should be looking out for in the future?

[Buzz]

Wayne I was kind of thinking, a quarter stick of TNT in each one would do the trick. Go figure I got the 4th machine to except coins and it only took me 10 minutes. Bet I worked on it 3 hours yesterday, and got no where. I know the key set up is wrong,  but everything works. I guess if I lived in Bosie I could F*** with it but I don't, so I won't.

David I didn't see your post.   I did have one bad Comparitor in my mix of parts. Someone correct me if I'm wrong on this, A S+ or Bally 5500 if the comp. is bad the coin will go to the tray. In my case yesterday I had a Green light on the Comp. and the coin would go to the hopper, but it turned out the Comp. is bad. Ian said in this thread the Comp. has to send a pulse (he hit that one right on the head) I would guess to the I/O board and back to the coin optics.

... Ian said in this thread the Comp. has to send a pulse (he hit that one right on the head) I would guess to the I/O board and back to the coin optics. 

Buzz, from what Ian said, the comparitor doesn't send a pulse back to the optics, it sends a pulse (changes it's voltage state) to the MPU board. The program (in the SG chip) that runs the machine looks for a combination of signal state changes from the compaitor and then from the optic board in the specific order that he posted and within a specific time frame (in milliseconds) to validate that a coin passed through the assembly correctly. The voltage changes represent binary data of either 0 (low voltage state) or 1 (high voltage state).

But I thought you said that taking a pick to the female connectors on the optic board harness and spraying contact cleaner on the (male?) connections is what solved the problem.

So Buzz,

Are you saying that you have to lube up the male and stick it into the female that you were working on with your pick???

I am just glad that you got them going finally!

Hi

Glad you got it working - I hate it when you change so many things and all of a sudden the machine starts working you dont actually know what the problem was. In this case it sound like the female connectors stretched and were not making contact. They are pricey but a set of Molex extractors are always good to have.

Just a little correction to my oiginal post. The optics and comp work through the IO board to the MPU board. I will have a look at exactly where the various IO's are in the S2000 menu structure.

Good job Buzz,
It sounds like you're on your way to getting these puppies up and running like they should! 
I've been following this post and doing constructive thinking on it.
I believe here's a rundown on the problem.>>>

A bad female receptor pin making bad/weak contact with
the male pin connector could cause flaky, erratic
timing errors and thereby forcing the MPU to send out
a "coin-in" error code to the display.

Does this sound logical to everyone?
I'm wondering if I'm on the right track.

Hello All

For future reference - To test the individual optics

Press Test switch on MPU and select using appropriate buttons
4.1 IO Tests
4.1.1 Door Input
4.1.1.1 Standard

Now scroll between
Coin In 1 - Default State 1 - A Optic
Coin In 2 - Default State 1 - B Optic
Coin In 3 - Default State 0 - Comp Pulse

Check each IO for state change individually. Loose wire / to big coin guide / faulty optic / faulty comp and one or more wont change state in expected sequence and cause a tilt.
