Relay Board Schematics

[gerrimat]

Everyone, I have sent the Schematics of the Relay board to David R.
for hosting. You should be able to download it shortly.

Fantastic!

[logicprobe]

Very nice work, Gerrimat!

[Lazarus]

Now if I just had the know how to use it! :oops:

Now if I just had the know how to use it!

This is the board that makes a bunch of racket in my Harley machine every time the joystick is pushed to start the reels. What's up with that? :smt102

[logicprobe]

That's the token-in relay (RLY1 on this diagram), ticking off the tokens played. Does it make 3 ticks on a max-bet and spin?

You can probably hear ticking after a payout too... from RLY2.

does anyone know how to print it out so it fits perfectly on 1 piece of standard paper?

Just stick the JPG in a blank Word document and drag it to fit.

So you cats like my work? I take it that's an affirmative.

I put the board back into my Seven Vs Dollars and I'm having a blast
with the machine. The kids hit the bonus round tonight and the music
kept changing and its really great.

I want to tear out the cpu board to do a schematic on it but they won't
let me. So I'm trying to get another machine to take apart.

Or... Does anyone have another board you would like to have a schematic for and will share it with the forum...

As I said I do this for a living and its fun for me to do...

Enjoy the fruits of my labors and learn...!

Sure is purty, and I know it took a lot of work, but I dont have a clue as to what it is except its a PC board ,can we put amotor and some tars on it and race it :?: :grin:

[gerrimat]

I 2nd that motion. I love my cars to. Come to think of it hows about
we turn a whole are into a Pachi Machine... Woof!

Go out and find a highschool child to read the schematic for you.

Actually for the techi heads around here its step one in a learning
curve that will accelerate if I have anything to do with it.

I just missed picking up a Legend of the Flower on Ebay tonight.

I have a couple machines I'm watching from my list and my mom is
so thrilled with my Net machine at the ripe old age of 75 she now
wants it in my living room as a conversation piece, and she wants
me to get a machine for each of my sisters families. Total of 3 more.

This is starting to snowball...

Im just havin some fun , you will get used to me , I race RC cars , i/5 scale,I know how it is , I have 4 plus a pichinko, Vintage verson that Ive had for at least 25 years

I was just looking over the schematic and noticed a line that says bonus round signal. Does that mean we could have a push button to automatically start the bonus round. I am probably wrong since I know nothing about wiring schematics but it sparked my interest so I thought i'd ask.

[TANK]

exactly the opposite. this is an output signal to a remote site to let them know when the machine goes into rb bb etc.

[alexilla]

Oh, wow, I was way off. Thanks for the info!

[TANK]

it would appear that you can disconnect wires 5-9 and eliminate the peskey relay clatter with no effect to the playability of the game? am i right?heck it would appear the only useful wires are: 1,2,4 and 24-30.

[Czyotto]

I noticed that the picture of the relay stop board is the same one that Robert from Pachislo USA uses in his mod for adding counting meters.

[lockburn]

Wow, great work!

I was looking to make an adapter to monitor the machines, report payouts to my PC, etc. This will definately help.

BTW, what is a CT bonus, and also, does the token out signal go high when a token is physically ejected from the machine, or credited? For example, if I am playing in credits mode and win 15 tokens (but they don't dispense into the hopper), will I be able to observe this from the token out line, or will I only see it when I cash out?

I'm eagerly awaiting your CPU board schematic! I'm hoping there is an RS-232 or 422 bus to get the same data out, would make my interface much simpler!

[gerrimat]

Yes, first the picture is one that I picked up on the NET. This is a
photo of the board the matches mine. My digital camera doesn't
focus in this close. So if its from Roberts site I appologize for not
giving him credit. I simply packaged up 3 versions of the schematic
and the photo that I had and sent it to David for posting.

Now as for signals, in order to use any of the relay outputs you
must provide an external voltage source of some kind to provide
energy to the contacts. Since all of the contacts are tied to a common
signal which would typically be Ground based on the way that the
Japanese tend to apply or switch grounds then you would need to
provide say +24V to with your target such as a light or a counter
wired between the board on one side and the +24Volts on the other.

There is a good reason for switching ground on and off a ground line
it helps to reduce externally induced noise into the pcb. If you notice
there is a resister/ capacitor filter attached to each output line to the
CN4 Connector. Each of these filters assists in clipping off noise from
the lines when the relays switch along with protecting the relay contacts
and extend their lives.

I used to work for a railroad signalling company and relay designs were
one of the first types of circuits that I learned to design with.

Now if I was going to use this for driving an external device I would use
a lower voltage like +5Volts on the relay contacts and drive an opto
isolator like an H11A1 or something similar and use the Optoisolator to
provide me a barrier seperating the external higher voltage device
from my logic level pcb.

I wish that there had been an RS-232 on this pcb. More than likely
there will be something on a CPU board for external communications,
since I always design my circuits with communications, I figure that
these guys must do the same.

As for a CPU board... I will have to talk to At-Slots to see if he has
any that I could borrow and map a circuit out for.

Of course since there are more than 10 manufactures so there will be
some differences between them. I have noticed that in Aruze machines
there appears to be a 2nd board mounted to the back of the machine
and one on the left hand side wall the pair looks like a reel controller
and the cpu board... This is speculation on my part right now.

Anyway, until I get another machine to tear apart or the loan of a board
to analyze it will be a bit of time until I get the next schematic designed
and loaded up.

Again I appologize to Robert for using his board image...
