New Life Games Tech Forums

My company has assigned me a project on creating a device that allows me to remotely add credits to a machine. (via handing the cashier $$ and she inputs the amount to device).

The machine type and etc are somewhat irrevelant simply because we are just trying to duplicate the DBVs pulse signal from a different device.
Currently our machines are running DBV-200-SG with new $5 chips.

Sorry if Im not being too clear on what im needing help with, but if you think you can help, please ask questions!


Thanks,

Will.

Hello Wiil

Unfortunately it will be machine specific as there are a number of different protocols for different manufacturers. You can check out the JCM website there is a breakdown somewhere of which protocol goes with each machine. Unfortunately the protocols are not available to the public for security reasons. You can also do this via the machine itself via the SAS protocol if it supports EFT/AFT. From what i understand you have to be a member of the GSA and sign a NDA with IGT to obtain this protocol.

Say I put one DBV-200 behind the counter, using a switch for the cashier to toggle Mach1, Mach2, Mach3, Mach4.

Basically you would have the single validator giving inputs to the switch, then turn to machine 2 for example, insert $20 and it continues
the signal to the machine.. just like the validator was plugged into machine 2. (The same for 1, 3 ,4 etc).

My question is where to find such a switch.

Check and see if RKS still makes the goose it system It will be much easer.

Hello

For this project, do you need the conditions write for TZtech, do you need many signals that depends sometimes from manufacter, for example smyley bill acceptor models use many sinals for communications like vending signals, the igt works whit id022, 023, 024, under 022 and 023 some signals could be ignorated, do you need work whit inhibit signals for send data properly, however under id 024 netplex do you need a special procedures, based in this language, and the machine uses all signals, like bill acceptor status,enable or disable, stacker present or missing and properly times to send data info, under other models williams bally, atronic do you need a id003 this works under serial, (op-Bell) can help you whit his aknowledge about jcm units, this protocoll needs the properly signals and times to emulate properly, under sas is more easy, enabling aft/eft transactions, for igt sas licenses do you need.

1-you don´t be a operator machines.

2-Work As Software developer

they give you all info about sas, when both sign a confidential agreement.

good luck whit this project is a excellent idea.

Thank you for your reply, although I think you're reading a bit too far into the situation.
I'm not trying to break the code on the pulse or protocol, I'm simply try to run 4 machines from 1 validator using a Switch box of some kind, enabling
a person to simply turn the switch to #1,2,3 or 4 and then insert money, and the machine functions like normal from that point.

I have 4 complete machines that already work with the DBV-200 and stacker.

Here is a poorly drawn diagram of what I'm trying to do:

Again, thanks for your comments and suggestions.

I think it's an awesome idea...
Think of it this way...

Pay the cashier $20 , then turn around and
run out to your car and
pump in $20 worth of gas.

Cool!

Hell of a lot less DBV's to deal with and only one cash box!

JCM will never go for it or support you on this I'm afraid....
You've just saved casinos millions of dollars!!!

Then again, maybe not...they've already went to credit card systems...ARGHHH!

I have no idea what I am talking about...lol.

But if you use a switch....3 of the machines will have the DBV disconnected from the machine when they are not selected.  Will the slot have issue with that?  Do slot machines require a constant connection to the DBV?  If I remember on my IGT machines, if I disconnect the DBV from my machine - I will get an error on my machine and will not be able to play.  This could be a problem with your idea of a switch....

Dan #2

My machines will not give an error or alarm if I unplug the DBV and plug it back in.

I have no idea what I am talking about either...lol.
But, I think the DBV did it's job already of validating the credits with the particular machine...
the credits are already in the machine and don't need the DBV anymore to play it?
As far as a switch, how about a hotel telephone switcher?
Switch and "close" only one wire per machine...such as the DBV power line to a particular machine?
Or leave the DBV power line on, just "close" the pulse/signal in line instead?

ok, I'll grab a KVM RJ45 'ABCD' switch box and wire everything up and let ya know how it goes.

I was just going to suggest that - but not a KVM - not sure if you will have enough wires - but a serial/parallel switchbox like the one pictured below - that would have up to 25 wires you could use.  Then you would just need to make the correct cables between the machines and the switchbox.

Dan #2

Exactly! I can't remember off the top of my head but I really think i'll be good with 8 wires. If not, that serial KVM will work fine.

I'll be pleased to help, but I need to know what kind of machines they are because, as has been mentioned, there are many different interface protocols, and this affects the way you switch the signals. It should be easy enough, as long as the game software doesn't go into tilt when it doesn't get an answer back from the BV.

Old school stuff like Cyberdyne and a few others.. We've changed many aspects of the machine over time to suit our needs, so they are basically Frankensteins as far as
Im concerned. I will double-test the DBV theory tomorrow about it not alarming when unplugged.

I will insert $20, unplug, play, then plug it back in and insert another $20.  I'm 99% sure this can be done with no alarm or interupt in play.

The only thing I will add - sometimes electronics in slot machines can be damaged by unplugging them with the power on - I assume you plan on using this switch box a lot throughout the day...could this possibly damage the DBV or the slot itself?

Dan #2

I know exactly what you mean - And I feel the same way... Im not saying you're wrong (because I know you arent), we've been doin it that way for 12yrs now. Whether or not
we've done damage to a part or whatever, it seems so unlikely and minimal that we hot-swap everything to this day.

That's why I think you should only switch the single DBV's "pulse output wire" (one wire only)
 but leave the power on the one DBV all the time.

Correct, did you see my awesome diagram ? :)

There may be a difference between unplugging with the door open and unplugging with the door closed.  If it doesn't work, you could just hook up 4 BVs behind the counter, and that may be more cashier friendly, reducing the possibility of the switch being on the wrong machine.

Thanks,
Wayne

I wonder if the DBV's will communicate to the machine on wires that long?
There's must be some limit on the length/gauge of wiring that can be used perhaps?

Wont be more than 100ft i would imagine, but we could always compensate for that.

I tried something similar to this about five years ago. back in the day when machines were made without embedded bill acceptors, they had made a unit they  put on the side,thus called side mount validators. these were basically the complete unit, head, transport, power supply, cash can etc. they had to be mounted to the unit, a hole drilled in the cabinet and the comms cable and power were supplied to the unit. I could never get it to work,I had a customer that had four machines and we thought we could share one side mount between them. I think the electronic ground between the machines was the problem, could never prove it , but after several hours and bumps on the head I gave up.  one suggestion to keep in mind - the power supply for the 145/200 head contains two seperate circuits. the 12vdc power supply and the interface for the bill acceptor to the logic board itself.

Good Luck with this , hope you have better results

Jim

mil gracias. excelente ayuda.
