CDS Proview S-2000 Machine Hook up

[morspeed]

I got the email already. What I am Saying is I'm am not sure what you are referring to on page five or I don't have the same manual you are talking about.

[stayouttadabunker]

be right back

[stayouttadabunker]

okay...did ya get it?
This picture was on page 5.
There's two attachments to this post...ones a picture (not very clear really),
the other is a link to a converted picture file of the board from the manual
on page 5. (much clearer !)

That top plug is marked rs232. What do you suppose that means I have been thinking about this for a while and I got nothing.

[stayouttadabunker]

It's a different way of communicating between boards before serial ports came out.

[brichter]

RS-232 is a serial communications protocol.

[stayouttadabunker]

Thanks...I was thinking of RS-485 perhaps?

[brichter]

That's another serial comm protocol...

[stayouttadabunker]

okay...good.
From what I understand...
The RS-232 is configured to use a connector much like a 9-pin (DB something) serial plug.

[brichter]

Actually, the RS-232 interface has several defined physical interfaces, including RJ-45, DB-9, sub DB-15 and DB-15, and DB-25. The standard calls for 22 separate wires in the full implementation, but since it also functions with a bare bones minimum of 3 wires, smalll 1/8" (3.5mm) (Stereo) jacks have been used on a lot of devices, like changing channels on my old Motorola Cable TV box. My Tivo had a 9 pin to 3.5mm audio plug cable that went to the cable box so the Tivo could change the channels.

And then you can get into handshaking, modem, null-modem, etc. so the actual wiring of those physical interfaces can be different depending on the application and is a constant pain in the butt.

It looks like the white connector in your picture is a 3 wire implementation...

Bunko Rs232 doesn't have a keypad or Pelco-d either !

[stayouttadabunker]

Maybe this might come handy?
I googled it from wikipedia.com>>>


3-wire and 5-wire RS-232

A minimal "3-wire" RS-232 connection consisting only of transmit data,
receive data, and ground, is commonly used when the full facilities of RS-232 are not required.
Even a two-wire connection (data and ground) can be used if the data flow is one way
(for example, a digital postal scale that periodically sends a weight reading, or
a GPS receiver that periodically sends position, if no configuration via RS-232 is necessary).
When only hardware flow control is required in addition to two-way data,
the RTS and CTS lines are added in a 5-wire version.

Jay,
I think they make RS-232 serial cables to attach to keypads like this.
I don't think it would work with a ProLink though...>>>

I can pretty much guaraantee it would not due to this in the specs:

Interface:
Type RS232C (1200 baud) proprietary ASCII

Having a proprietary ASCII interface means you'd have to load a driver or develop some type of gateway device to go between your CDS Prolink and this keypad after you reverse-engineered their signaling (unless Prolink uses a keypad device that outputs the same proprietary ASCII codes... )

[morspeed]

I'm not sure where you are going with this but the back of the prolink that hooks to the computer say RS232 and not RS232C.

[brichter]

The "C" in RS-232C is just one of the standards revisions. They make revisions to improve the capbilities and add features occasionally, but backwards compatibility is not compromised.

[morspeed]

I don't know but I am about ready to throw this thing in the trash!!! I don't know if the machine is correctly hooked to the prolink. I don't know how or where to hook the meter out of the pro link to the accelerator board. When I hook the pro link to the S2000 I get no lights lighting Except the power light. ARRGH!!!!!!!!!!!!!!!!!!!! No good info anywhere on these things that explains anything. It is just plug this is and run this program. What kind of manual is that?

[brichter]

Well, documentation has come a long way in a couple of decades...


They never documented this type of stuff back in the day because they never realized people would be interested in it, let alone need it!
Nowadays it's assumed that almost everything needs to be documented at some point unless it's proprietary or IP (intellectual property).


<edit>

now, I don't have the manual so I can't say exactly what your hookup needs to be, but if this thing behaves the way the rest of the progressive controllers do, then your output (coin in pulses) fron the slot machine to the controller come on the pins in bunker's first section: 1-4 and pin 37. the way an S+ signals coins in is with a momentary short between a signal pin and a ground pin. The signal pin in this example would connect to the lower number pins (Bunker uses 1 through 4) and the ground would be pin 37.

The feedback to the machine would be on pins 6 and 7, one of them would probably be data (RxD, receive data) and ground. IGT and Mikohn use the same ground for the coin in and RxD lines, so there's only 3: Coin in, ground, and RxD (Mikohn calls it signal return, it's the signal the prog controller returns to the slot machine).

Send me the manual, let me get a look at it.

[stayouttadabunker]

This is the ProLink manual
The appendices are missing though.>>>

[brichter]

That manual is corrupt, all the diagrams in the appendices have been removed.

Morspeed, try this. The TxD from the slot machine to the Prolink is easy, the only connection I'm unclear about is the RxD from the Prolink back to the S2k:

purpose                     J15 S2k                   Prolink
RxD (CDS>S2k)           Pin 1                      Pin 6    Game Serial
Gnd (common)            Pin 2                      Pin 37  Game I/O
TxD (S2k>CDS)           Pin 3                      Pin 1    Game I/O

Now, here's the tricky part, since we don't have a definition for the CDS game Serial pins 6 and 7:

1) There are 2 wires to the Game Serial on pins 6 and 7 from looking at Bunker's harness pinouts. One of those is RxD back to the slot machine, the other is ground. The S2k uses a common ground for both the TxD and RxD, so your initial connection would probably be to try Pin 1 of J15 on the S2k to pin 6 of the Game Serial on the CDS. If you get no comms, then try Pin 1/J15 to Pin 7/Game Serial. If you get no comms there, then it's possible the Prolink can't handle the common ground.

So, next step is to use 2 wires out of Pin 2/J15, one to Game I/O 37, and the other to Game Serial. So, now your Game Serial connection will look like J15 pins 1 and 2 going to Game Serial pins 6 and 7. Try both ways (1 to 6 and 2 to 7, then 1 to 7 and 2 to 6), checking for comms on each.

If none of these permutations work, either your setup is wrong on the Prolink, you don't have the S2k configured for a link progressive, or the Prolink is not compatible with the S2k protocol.

The only thing that has me    is the note about the host needing to provide a 750 Ohm pullup resistor between pins 3 and 4 on the S2k. It may be that the S2k expects to see the RxD line high when idle and pulses switched low for comms, you may be able to either configure that in the Prolink or provide that connection yourself on the harness. Providing the connection yourself would be a last-ditch effort if all else fails, and would be an attempt to hack the Prolink's incompatibility with the S2k.

Good luck!

yeah well I was playing with the pin outs like britcher was talking about and got nothing so I added a ground/common and tried both pins and one way smoked the prolink so this is probably a mute point for me but not for you bunker. Keep trying. I'm sure my prolink is no longer any good if it even was in the first place. Time to put the key chip in and change linked progressive back so I can get out of tilt.

So, what do you mean by "smoked"? Connecting TxD or RxD to ground shouldn't "smoke" anything. Did you really see ?

Also, for Bunker's knowledge, which combination caused this? I'm sure he'll want to rule it out as a possible combination...

[stayouttadabunker]

I hate that smell... 


If you want morspeed,
send it to me and I'll see if I can get it back running again?
I can compare your board components to mine and replace what's no good.
I PM'd you my address.

[morspeed]

(1 to 6 and 2 to 7, then 1 to 7 and 2 to 6) Don't try either of these.
That's just my suggestion.

That's not the same manual and doesn't have the appendices necessary. However, if you look at the Game King harness pictured, it shows what I described as being the correct hookup, as Pin 1 on the GK side goes to pin 3 on the CDS side, pin 2 igoes to pin 2, and pin 3 on the GK side goes to pin 1. Note that the pictured "pigtail" would still connect to the Prolink Game I/O data harnesss pictured on page 2.

It doesn't do Morspeed a whole lot of good now, but does validate the that the Prolink doesn't need a separate ground for the data return to the slot machine since it only shows 3 wires in the pigtail.
