SAS Host controller DLL. What do you want to see?

[jay]

Very cool everyone.

SO - now that we have 1 machine communicating. How do we poll multiple S+ machines with only 1 RS232 on the PC ?

Do these boards then interconnect with Fiber ? or do you need to have a separate RS232 to each machine.

Mark were you able to transfer credits to the machine ?

Yes...it works "magically" ! lol

I'd imagine all you to do is assign an address to each machine
through the settings and the Test App will poll each one?

[stayouttadabunker]

Here's my settings in an S+ using Double Cherry 3CM with a SP1271 game chip.>>>




Using SET088, I set the Accounting System Communication Type to: IGT SAS {2}  

SAS Communication Addy <0>, I set the address to: {001}

Bill Pay Mode<0> : "self-test selectable" {1}

Bill Acceptor <0> [9] :   enabled {1}

Coupon Capability or EFT <0> [11] : EFT enabled {1}

Country code <0> [30} :  US {37}

Progressive Selection <0> [31] : none {0}

Progressive Levels  <0> [35] : Didn't touch. Defaults to {1}

Progressive Type <0> [60] : Didn't touch. Defaults to {0}

SAS Progressive <0>[63] : Didn't touch. Defaults to {1}

SAS Bonusing <0> [64] : Disabled {0}

Denomination <6>: .25 cents

Standalone Progressive Setup <9> : Didn't touch.




I put SP1271 back in, closed door , got [61], pressed Test button for 2 seconds, "Ding!" [61-1},
closed door and turned Reset key once.
The reels spun their maiden spin to the pay line and the S+ immediately
communicates " Closed The Door" data to PC !

Hi To All

Awesome news good for all , about multiple connections in one serial port, maybe it´s neccesary consider some things, because too many connections, make port buffer to collapsing, for each com port you can put 32 devices. and the sas protocol whit this feature in some occasions lose data packages, maybe all here can join knowledeges and build a properly interface to this purposses.
 
Best Regards

SAS looks to be small groups of bytes, probably no more than 128 bytes at a time.

Which baard do I need for the S+ and does anyone have one I can have?

[stayouttadabunker]

There's one that appears to look like mine on ebazz.
It is a hard-wired one.
It goes on the back wall of the cabinet over the rear mounted MPU under the reel shelf.
I'm using an ASSY NO 7542200 board at the moment...
Stay away from the fiber optic boards...we have no way to to hook it up to a PC at this time. >>>

These boards are going to become gold 

Which power option did you end up using ?

Should this not be enabled ?     SAS Bonusing <0> [64] : Disabled {0}

[knagl]

Should this not be enabled ?     SAS Bonusing <0> [64] : Disabled {0}

I was wondering about that, too. 

[jay]

Do you need the power brick like this guy has listed ?

I don't think so.  In fact, in the auction he mentions that he doesn't think that wall wart belongs to the board as he said there's no place for it to plug in.

You cannot poll multiple machines with rs232. You need to use something like rs485 that has a transmitter that goes high impedance when no data is being sent. If you try and hook multiple machines to rs232 the outputs from the transmitters will clash.

Dont write of the fibre just yet, I will add the option to use it. I have just been focusing on getting a single point running with some basic messages to this point. Adding support for fibre is not really hard, its just another thing on the list and at this point I have it below TITO. If you guys want me to get fibre going first, let me know.

[Magicslots]

I dont know about the rest of the guys on here  Most of this stuff is way the hell over my head 
But for me, AndyP, Please  TITO  TITO  TITO 

[jdkmunch]

Yeah TITO is the dream here.  I was thinking of hooking up
Several slots to a tcpip network via an rs232 converter.
I've done this before with other serial devices.

[jay]

TITO would be apeasing to the mob......

What do you envision the PC interface to be for the fiber ?

[jdkmunch]

I also have fiber to 100baseT / 1000baseT adapters.

Just google

[Foster]

I think IGT is using RS232 type transmission even over fiber
The RS232 chip on the S2000 is just a line driver/receiver, TTL/CMOS Logic to/from RS232 levels
All they send is various characters with the wake up bit at the beginning.

Those of you that are electronic gurus might be able to see that if you look at the S2000 comm board and its equivalent in the S+

In Other words IGT is trying to keep GM and backroom system interconnecting and programming simple.

Yes RS232 is slow compared to 10/100/1000 networking standards, but your S2000, S+ is not sending a graphics file or large amounts of data.
It and the host system probably only transmit about one line of text at a time.
and most packets are probably only about 3-10 bytes long.

[jdkmunch]

We should be able to use the rs232 adapters
Over tcpip with the test app to do tito


One step at a time I suppose.   I need to buy
From someone the  plug for the slot machine end to
Make the rs232 cable.   

Will be back online Sunday -  night all

[AndyP]

The fibre optic is not complex, it just requires a serial to fibre converter. The interface cards posted up here earlier can do that job. All you do is connect the rs232 side of the fibre converter to your pc. I just need to change my code so that it can handle reflected packets (ie data I send out on fibre comes back in, with the VGM packet following.

Anyway, when I get around to getting a new phone with a working camera I will take some pics of my interface card collection here.

For now I will work on getting TITO working, then worry about fibre.

[Foster]

I know some data is repeated or echoed with some changes for certain things to happen.
Voucher/ticket redeemption is one of them.

[poppo]

Wow, a lot was posted today.

To answer this, you can either power the uint with a wall wart or use the power from J9 (on a S+). Although that one shown is probably not for the unit.

As I noted above the schematic for the fiber board appears to be almost identical to that of the RS232 board. The only real difference is the fiber 'optic' is connected before/after the 74HC14 instead of going into the MAX232. Actually all a MAX232 chip does is bring the TTL signals up to the standard RS232 voltage levels. Some RS232 ports will actually work at TTL levels. In theory one could connect the TX and RX lines directly to the S+ and it 'might' work. There is no other protocol changing taking place.

Correct poppo. The only difference is that the signals use light instead of electricity. The protocol remains the same regardless of the format. The speed over fibre is 19200 baud, just as it is over rs232. Both use 8 bit data, with a wakeup bit.

Ok, for any of the electronics folks, here is a really crude schematic of the S+ SAS interface board. I used pictures of the original board to trace most of it out. It does not have the 'status' LEDs and I don't show the value of the pull up resistors on the opto-isolator (I need to look them up). Of course you need a 5v supply too, but you should get the idea.

All that happens is the signal out of the S+ goes though the opti-isolator, goes through two hex inverters, then goes into the MAX232 to be converted to RS232 levels. The signal from the PC goes though the MAX232 to convert to TTL levels, goes through 2 hex inverters, and though the opto-isolator back to the S+.

It would be pretty easy to breadboard one of these. Actually IMO the opto-isolator could be eliminated. It's more of a safety thing than anything to totally isolate the unit.

The opto is used to source or sink the current. Not sure what current the loop requires, but it may be possible to do with just some resistors and the max 232.

I have to dissagree. It's used for electical isolation. The input/output on the MPU are just TTL level signals. The fiber optic board does not even use them because the isolation is done by the fiber cable its self. The signal goes right into the hex inverters and straight out of a TTL AND driver.
