Very close to working TITO

[poppo]

And since it's a level converter, TX and RX may be referring to the input to the board (or not). In other words TX may go to TX and RX may go to RX on the amicus. I've had converter boards labled both ways.  

[poppo]

I wonder if I can power the max with the
Amicus

You should be able to. The max232 only needs +5VDC

[vtyler]

the top pin header looks like it says 5V the amicus shows a power pin header that does have 5v out and looking at the manual your tx and rx pins are on the port C header not sure where you would put the signal gnd.

i have had problems with this also i recently stuck a windows pc in a evo cabinet the touch screen tx and rx kept getting crossed.

what is the model for the 232 board it we can get a schematic we may be able to help determine the wiring.

[poppo]

If he can see what pins on the MAX232 chip the TX and RX header goes to, we can tell which direction they are talking about.

On a similar note, the 9 pin plug may have a male or female plug, and that will help detrmine which pins are TX and RX on that end.

Connections for RS232 Module to IGT Comms board

J82 On interface Board                             Male DB to connect to RS232 Module

1    TX         ----------   Blue    ----------   TX   3
2    RX         ----------  Green   ----------    RX  2
3    NC
4    NC
5    GND      -----------  Black   ----------    Gnd 5

Amicus To RS232 Module

RC7 - RX   ----------- Green ----------   TXD
RC6 - TX   ----------- Yellow ----------   RXD
GND         -----------   Black  ---------- GND
5V            -----------  Red    ----------   +5V 

as per Poppo's post RX and TX may be labelled differently on your module

I don't have much time tonight - but is it possible the cable from the max232 is too long ?   I had it working with short 8" wire
from max232 to slot

i re-ran wire from slot to out side of cabinet - about 3 feet and now i can't get it to work.

at most I see 80 - 80 flashing really fast

[poppo]

It shouldn't be. I've run cables longer than that (TTL level RS232). After conversion to standard RS232 you can go WAY farther.  TX & RX swapped?

[vtyler]

if its on the rs232 side length can be affected by a lot of things, but normal length is 10 to 150 feet depending on the variables. if you know the cable is good and the wiring is correct you may want to check you power source. if your powering the level converter from the amicus make sure that the power supply can handle the load of the amicus, the level converter. and any other divides your running powered by the amicus board.

[jdkmunch]

The long wire is from the slot to the max adapter.
I'm going to solider the splice I made because
The wire is solid and connection to the slot is stranded - so
It can easily come apart.

[TZtech]

Twist the RX and TX wire pairs together
If You can use shielded cable even better (A lenght of  network cable will probably be easiest to use)

[jdkmunch]

That's a great idea -  I will make the network cable now

[jdkmunch]

Network cable worked like a charm.

System is now up and running.  I can generate credits from lamp switch or inserting a ticket.  Working now on getting ticket accepted with $ value

Quick Update

We are 95% there to standalone TITO.
In Bhinkley's thread Tom4100 suggested the following

by using 'system' generated validation, in other words, the microcontroller will interogate the machine for the credit amount then encode that number in the 'system' generated validation number printed on the ticket, this eliminates the need for a "back-end" database management system

This approach makes perfect sense for a standole in machine controller and has been added to the SAS @ Home project.

Thanks to JDKMunch who patiently tried many code revisions over the weekend we can now print a ticket with the ticket value as the validation number and also accept that ticket. Only problem now is accept routine only works once but hoping to sort that out soon.

Credit to Zarobhr for his CRC routine - Foster for posting TITO transaction sequences and of course JDKMunch.

100% working

that is awsummmmmm 

[poppo]

Good job.

WAT TO GO 

[kibble]

this is really awesome

[jdkmunch]

It is -  

Buy a board for each of your machines - and you will be able to move from one to the other with your tickets.

So Start of with $100 in one - and bounce around to any other!  

[kibble]

I was ecstatic when i got the code from tztech just to be able to get the Amicus to work on my s2000, just changed  3 lines of code to get it to take the ticket and add credits and spit the ticket back out.

[jdkmunch]

Yep - I prefer the tickets going in the cash can though -

For me - If the ticket pops out then why not have the change lamp add $$ - 

for each is own though - whatever you makes you enjoy the machines is what it's all about!

[zarobhr]

I like mine to Simulate thae casino as much as possible

[vtyler]

a board should be designed so you don't have to have a full sized dev board in the machine. what kind of machines would it work on.
