Yah...it's somewhere in that big 40 page thread on SAS stuff we did last year.
All the wiring pinouts and computer/laptop hookups are discussed in it.
We entered all kinds of pictures, drawings but didn't win any awards...  Cry Laughing

You can talk to the DCS port at 5V TTL levels on the S+ and PE+ and also on the S2000 and I Game platforms. Have a look at this thread - http://newlifegames.net/nlg/index.php?topic=11893.0

When looking at the post referenced above it looks like it is just a USB to 232 using a max232 chip.  Where is the 5V being picked up from?  Also, there is a white wire on the DCS plug and not the PCB.

The S2000 has a RS232 interface built in to the Comm board.
It is J85 (5 pin)

Hello Slotman

The datasheet for the FTDI USB To Serial TTL convertor is here - http://www.ftdichip.com/Support/Documents/DataSheets/Cables/DS_TTL-232R_PCB.pdf
A piece of white paper was probably not the best background Duh!  but there is another row of pins on the other side of the PCB. White is connected to the center pin (Right under the brown)

available from Mouser - http://za.mouser.com/ProductDetail/FTDI/TTL-232R-5V-PCB/?qs=sGAEpiMZZMtf8aSAtgR7DlrGCyipOcry

I have two of these and use them all the time to interface to various devices - It was also the least expensive FDI device I could source locally.

If you are going to buy I would however get this one - http://za.mouser.com/ProductDetail/FTDI/TTL-232R-5V-WE/?qs=sGAEpiMZZMtf8aSAtgR7DtM6b7hTwLVv
this uses the exact same PCB as the first device but is molded into the plug and terminated into a 1.8 metre wire. All you would need is to add the connectors and plug at the other end

the upgrade to that cable is here - http://za.mouser.com/ProductDetail/FTDI/TTL-232RG-VSW5V-WE/?qs=sGAEpiMZZMsyM1rGGtQxrO%2fras%252bafkMw.
I see the price difference at Mouser is much smaller than from my local supplier.

There is a good product summary of the FTDI cable range here - http://www.ftdichip.com/Products/Cables/USBTTLSerial.htm#TTL-232R-5V

Foster, are you sure it is J85 and not J82?  I am hooked in to J82 and keep getting a CRC error

Hi Slotman

J82 - There is a diagram for the comms board on reply 39 on this thread - http://newlifegames.net/nlg/index.php?topic=11467.25.
You have to set your SAS settings to channel 2 to talk to he comms board. Also check the ribbon cable from the comms board to the backplane - they work loose easily.

Hello All.

I'm new to the forum (a few months browsing and recently created an account) and have a question and maybe one of you have done this before.

Do you know if the schematics from poppo (using the 74H04 and RS232) works also on a DSC port of a Game King? I've built a protoboard as per specs but I don't receive anything from the game machine (tried 3 machines).
SAS is set to port 2, and the comm analyzer shows the address being written (01 01 01...), but nothing is showing in my PC terminal. I'm using an FTDI USB to serial cable (2.08 driver) and a terminal emulator.

Hope I'm not pushing by posting on such an old thread.

Although the connector is the same the wiring for the GK DCS port is a bit different (There should be a schematic somewhere in this section).
Would probably be much easier to use RS232 from the Commboard - Remeber to change to SAS port 3

That's fine, I'll give up on DSC for now!

Can you point me to the Comm Board pinout? I'm trying to avoid repost, but couldn't find it for GK.
I have 2 interfaces available in the GK's comm board. A 5 pin and a 6 pin cable.

Thanks again for your help. -Mosart

...and I'm in business, it works flawlessly (and simply, no interface circuit necessary).

Now I'm out to attempt a TITO system with the machines I have (All GKs for now).

This forum is great, thank you again for the help!

My intention is to use a raspberry pi. For now, I'm trying to get sastest (and tito emulator) running from a PC, just to understand the comm/protocol required for tito.

You are right, info is scattered, so I'll keep on searching...

The PI is a great paltform for this - Please keep us posted on Your progress.
I have got to the point where i can poll the EGM and decode events from the machine. the tricky bit of course is getting the 9th serial bit behaving properly - there is a link in this thread on how to get this working on the PI - http://newlifegames.net/nlg/index.php?topic=22224.0

I've been scratching my head with something stupid...  Scratch Head

How in heaven do I set the Validation ID in the Game King?

I used a key chip to set it up with Enhanced Validation, and SAS Redemption. Terminal id, etc, all in, however, any attempt to read returns a "Validation ID not configured". Same with TWA8000's Tito emulator.

I've read that 4C can override the id from the machine, but all I've read requires one to be set first.

Do you have Blue (AFT) or Red (EFT) menus ? Will have to check the manuals our sollutions use system generated validation numbers so this is something that has not come up before

Blue, I think (pic attached). I'm not familiar with the differences.
I'm thinking  this could be an option set in the key chip menu. I can't find it anywhere else. But again, I'm sure it's here...

Can you please post pics of the following screens

Setup - Comms Options - Validation and Redemption
Setup - Comms Options - IGT SAS - SAS Validation

If the options are greyed out it means You have to keychip to change.


Also dont know if you are aware of this - under diagnostics go to comms channel Analyzer and select port 3. this will show You comms to and from EGM to system and is very usefull to see exactly what the serial packets look like.

Sorry for the delay, I did not get notified by email of your reply. I will check the forum regularly...

Here are the screenshots. It looks like I can only set validation options via Key Chip Menu (but I couldn't find the "Validation ID").

(I'm in love with the COMM ANALYZER. It's a great tool)
