I have been given the unfortunate task of installing a DBV into a Skeeball (newer Model-S I think) where the ticket dispenser normally is. The DBV's I'm told I will be given are Rowe CBA-2's. My research indicates these run on +12vdc, so I have to figure out where to get +12vdc. Obviously I could install a switcher in the back and run wires for it, but if there is already a source I can use, that would be preferable. This +12 needs to be present anytime the game is on.

And if anyone knows anything about these CBA-2's, the info I've found elsewhere seems to indicate I need to run +5 to the $1 Enable in order for it to take $1 bills, correct? And then I set the pulses via dip switch, wire up the Ground and Coin Sw, and it should work?

I don't know why they couldn't have given me easy Mars Series 2000's. Those are easy to hook up in an arcade application - no matter what type of game...
 
BTW - Not sure what voltages the ticket dispenser runs on, but there is a 12v coin counter in that area, too.

I don't think that wiring will work, though. Doesn't the counter (and dispenser) work by having the voltage turned on by pulsing from the logic? That should mean that there isn't a steady +12 there are all times, right?
 
Unless you are going to charge $1.00 a game...don't waste your time. Model S games do not retain credits. If you coin a game up in the middle of a game, it will start over, not store a credit. So if the validator gave 4 pulses, it would start a game 4 times in a row. Newer Skeeball games, have "credits", Model S do not.

It's not my game, and yes they will be charging $1 per game. They run skeeball leagues and currently have about 200 members. They play on teams and each player plays 10 games each night. Not sure how many players actually play each night, but if they all do, that's $2000/night. :eek:

As for whether it has credits - this one is set on 50 cents/game, so it takes two quarters to start the game. Not sure if that means is holds credits or not, but I will set it to one pulse per $1 and for that to start a game.

Yes, I found that connector has +12 and +5 (and Ground) so that will be my power connector...
 
Rowe issued two seperate manuals on the CBA-2 bill acceptor. One manual covered vending machine applications only and the other covered jukebox & amusement applications.

There could be one of three different main boards in it too:

Early board without any motor speed or mag gain trimpots (takes old currency only)

Intermediate board with motor speed with motor speed and mag gain trimpots (takes old currency only)

Latest board with motor speed and mag gain trimpots (takes all the latest currency)
 
I've found a pinout and schematic. However, I need to know which wires the credit and return get hooked up to. I have a 2-pin connector that a jukebox manual labels as DATA A and DATA B. Are these just outputs? Should I connect my Credit wire to one, and my Return wire to ground? Or do I need to connect to both?
 
After perusing the schematics, I've determined that the DATA A line is one resistor away from a direct +5 connection, and the DATA B line is one resistor from a direct Ground connection. Using that logic, I will connect the Credit Hot wire to the DATA A and the Credit Ground wire to the DATA B and see what I get...
 
Okay, it's working. For those who may attempt this feat, here is what you need to know:

The DATA A and DATA B connector is for data transfer from vending or jukebox computer, and are not connected in an arcade application.

Apply +12 to the red wire (pin 1) and Ground to the black wire (pin 6) going to P2 on the side of the CBA-2. Apply the Credit line to Pin 4 of P2 and the Credit Ground to Pin 5 of P2. It only gives one pulse per dollar, so you have to set the settings on the game as to how many credits you get per pulse.

Now that I have it working, I can now figure out how to mount it so it doesn't look like shit...

So how did you get around the fact that it doesn't have tickets now and it will be looking for them ? (otherwise it calls for help)

Or did I miss something and it will still have a ticket dispenser connected.

You can turn the ticket dispenser off via dip switch on the board, so that it no longer looks for it. These newer ones even allow you to change the number of coins per credit. I set it to one coin one credit, then the DBV for one pulse ber bill, and $1 gives you a game.

On a different note, mounting this DBV was a big pain in the ass, as it was about 1/2" wider than the space provided. luckily the side walls are about 1" thick, so I was able to chisel out about 1/3" on each side down 5 inches so the DBV would fit down in there.

Of course, I'm going to have to do this again on another I have here once the new board arrives - they blew up the other one by trying to fix it themselves. Apparently the old DBV in one of their other machines stopped taking bills, so the guy opened up the area, saw a connecting unplugged, and plugged it in. It was an unused 120vac line that he connected to a +5 vdc line. One of the chips blew so bad that 3 legs were completely missing from the chip. I pulled the working board out of one of the two newer ones we had in the shop for their other location in order to fix it, and now need to wait on the new board before delivering it....

Ah.... I did not know that. All the ones I've ever messed with were at redemption locations, so never looked into disabling the dispensers.
This is good to know for home use machines for sure.
