What is the diverter/detector?

[ktbeasley]

I've been trying to make a little circuit to imitate the coin comparator on my reeltouch machine and, after following all the suggestions from various threads, I could not get it to work.  I ordered a complete coin-in mechanism for an s2000 so I could see what signals it put out but it didn't work either.  I think the problem is the reel touch machines have a diverter detector board and expect an additional signal.  When I ground the div/det wire in the harness, it shows up in the output test as coin-in 6.  Does anyone know what the diverter detector board is and what the machine expects to see from it?  I assume the signal tells the machine the coin went to the correct place (hopper or coin box, or whatever they call it).

The S2000 made simulating coin in a bit harder.
the Coin Comparator just compares a inserted coin against a sample coin and pulls the coin in signal to ground when the coin is good, it a short pulse you have to have a fast meter to see it occur.
At rest the coin Sense pin from the comparator is 13V.
The machine will not register a coin in until it passes the optics and if the coin sense is not signaled by the comparator first you will get a coin in error.

The coin in optics have 2 Infrared LED's and 2 Infrared photo transistors
The Collector of each photo transistor is connected to an input, both emitters connected to ground.

As the coin passes through the pair optics. they are blocked and unblocked in sequence, which also occurs quickly
its like this
A - first optic B second optic

A blocked, b unblocked
A and B  blocked
A unblocked B blocked

So you would have to pulse the Coin sense signal from logic 1 to 0 then pulse the A and B optic from 1 to 0 with an overlap where both optics are at 0 at for a short time.

Someplace the logic gets inverted so that while he optics are clear (unblocked) the MPU registers logic 1 and when blocked a 0

Here is the wiring diagram so you can tell what pin is what, I may have inverted the coin sense signal from the comparator,  I am doing it from memory.

Rudysdeals.com sells a setup for these machines already. Listed as a free play switch

I searched Rudy's sight and can't find it.  I just assumed they didn't sell them anymore.  I will keep looking.

Well Foster, that explains why my circuit doesn't work. I didn't know it did all that.  I wonder why the actual coin mechanism doesn't work. It is a complete unit with the two optics.  The comparator accepts the coin and it goes through the optics but all I get is a "coin in error".

Just noticed you posted a schematic.  My harness (P356) has 3 more wires in position 10,11,and 12.  10 is 13 Vdc, 11 is Div/Det and 12 is ground.  This may have something to do with why the coin mech I bought doesn't work.

The guy that owns the company,  John, is a member here. You might call him and see if they're going to get more

I will do that.  It would be great if they got some more, my "simple" circuit is getting more complicated by the minute.  Thanks!!

Update:  I got the real coin mech working.  I guess the coin optic a and b wire colors are reversed on a s2000 slant top ( the coin in assembly I bought for testing was from a slant top) .  I switched the wires and it worked.   The slant top coin assembly comes with what looks like a hopper plug on the back so I had to cut all the wires and wire it up myself.  I assumed I could just match colors but I guess not.
