Fault at 4892?
« on: October 12, 2017, 01:48:17 PM »

 I have a CEI poker game with a 906III Turbo+ board. It is getting an error of "Fault at 4892". I was able clear this once by removing cleaning and reseating the HN6264 in position u50. It then allowed me to see the game screen and access the settings menu. However, it was getting a MUX error which I was unable to clear. So, I thought I would try removing the battery (which reads at 3.6v) and see if it would allow me to reset and reprogram. But... Now, I'm back to the "Fault at 4892" error and I am unable to clear it now.
 
 Does this HN6264 have something to do with the above fault? Or, could this be something else? Any help would be Greatly Appreciated. I do not have a manual for this so, I do not know the fault codes.

 Well... I think I am back in the game. I replaced the socket on U50 and now I am back to the MUX error.

 Knock Knock.... Anybody?  :wave: Any suggestions? Could the Dallas on the multiplex card cause the MUX error?

I don't know much of anything specific about the CEI machines so this is just my thoughts. As they say, free advice is sometimes worth exactly what it costs.  :garfield:

-EDIT-
The error message you are getting "fault at 4892" doesn't mean error code 4892. The machine does a selftest when it is powered up, checks certain things such as ram and rom (prom or eprom) chips. These chips reside in the microprocessor address space and each address is numbered from 0 upward. That is how a microprocessor chip "talks" to the other chips on the mpu board, by putting the chips address on the address bus. Only the chip with that address will respond, others ignore it.

So the "4892" is probably the bus address where the selftest found a problem. The mux is a chip that handles several signals, one at a time but quickly, and it is controlled by the microprocessor. The "crc" terminology is similar to a checksum. So the machine is saying that during selftest the expected answer it got when it tested the mux was not correct. This may be because the mux chip itself is bad, or something the mux chip is connected to is causing the failure.

There are about 10 or so CEI manuals in the NLG download area. But because these machines had so many different game software sets that can be installed it is difficult to know if a manual is for your exact machine. I did see some that referenced having a CEI 906 III Turbo mpu board. But the software installed in the eproms makes all the difference on what testing and diagnostic features it will have. Access to all of these manuals is available to anyone that makes a donation to the NLG website, small or large donations are all appreciated. Keep in mind that many manuals don't have detailed circuit board repair information, they are written for casino employees on how to install and operate the machine, repair information is limited and usually has them replace the bad circuit board with another board. The manual may or may not have any schematic drawings for the mpu circuit board itself.

There are also other websites that have manuals for sale, here is one:

http://www.coinslots.com/

I personally think it is always a good idea to have whatever manuals you can find on these older machines. The people with experience about them are being lost every year so the amount of good help that is available decreases continually. This means you may be on your own for some problems, and any manual could be helpful. And I would think about buying spare parts when they come up for sale at a reasonable price. That will prolong your machine's working life.

Does your machine have a "Test" button or other way to enter test mode? If so you could try running the tests to gain more information.

Also, in your first post you mention the chip at U50 being an "HN6264". It is actually an "HM6264" (shown in your photo). That is a static ram memory ic, 8k in size. (has 8,192 storage locations)

So in your machine U50 is the HM6264 cmos memory chip, it isn't the mux chip. As you probably know the cmos chip is where the mpu stores information like financial data, number of coins in, coins paid out, etc. The cmos chip data is important so there is a battery on the mpu that keeps the cmos chip alive even if the machine is powered off.
 
Since this U50 cmos memory chip is in a socket it would be easy to replace. I don't know if that is causing the problem you have but it is worth a try.

There was a member here and on the old sight by the name of Dorme or something like that. He was or is the go to person on these CEI games. You might want to see if he might respond to a personal message. I know he was repairing the earlier 903/904 boards, but I'm not sure about the 906. You could also try reaching out to Alan at Klar in Las Vegas. I know he does some CEI Board work and might even have an extra 906 board that he might sell.
Please remember to make a donation to NLG for mine/our help in repairing your machines problem.. Your donations help keep this sight on line.
And remember...
If it's jammed, force it.. If it breaks, it needed to be replaced anyways...

rokgpsman,


 Thanks for your reply. The 4892 error was the primary issue. Then, when I replaced the socket I was able to get to the programming but, the MUX error always comes up. So, that's my main issue now. Also, you are correct about the HM6264. It was my fat fingers hitting the "N" and not the "M"  and not noticing it.  :banghead:


Amechanic,


 I did try PMing "dormi" but, his mail box is full. If push comes to shove I'll contact Alan.


I remember way back when we were making games it seemed like every other applicant was a CEI/United Coin employee. Where has all that knowledge gone? I do have a new Dallas coming for the multiplex board just to rule that out.

I see, so the 4892 error was a separate error than the mux error you now are getting and the new socket took care of the 4892 error.

Is the multiplexer board a small piggy back board that attaches to the main mpu board? If so, have you taken a close look at the pins and connectors used to connect the piggy back board to see if the soldering is ok? A lot of times hairline cracks occur where the long pins are soldered to the board and then they are intermittent.

Does your machine have a TEST feature?

rokgpsman,


 The multiplex board is mounted under the monitor shelf. Below are photos of it. As, for the test feature. I believe there is only a standard I/O test. But, I do not have a manual for this so, I can not be sure.

Your machine's circuit boards look a lot newer design and more sophisticated than the other CEI machines I have seen photos of. The date codes on the ic's show it is from the 1994 time period.

Is there a model name or number on the idplate?

63mini..


I was able to come up with Dormi's email address. I'll send it to you in a PM. Just tell him you got it from a member here. Hopefully he can offer some assistance to you error message.


rokgpsman..  I send it to you too for future reference.

ok, thanks! I hope he is doing fine and still active on this stuff. With all the past repairs he has done I wish he was here to give advice on this problem.

My best guess is the multiplexer board board is causing error that will not let the game play.  Do you get a different error with multiplexer board disconnected?

 Yes. Today, I disconnected it and powered it up. Got the same MUX error. But, this time it allowed me to reset. It went to game mode and allows me to play and program. It just now has the MUX error in white to the left of the cards.

Several programs I have for  he 906 turbo+ all have  mux error but play OK.  I have no hardware documentation for the multiplexer board wish I did.

Seems like there was a discussion about this on the old website, that some CEI/CalOmega machines would give the mux error but still play ok. It is odd if the machine was playing fine and not giving this error before, then started doing it recently. That would indicate something has changed, maybe an intermittent connection on the mux board? What is the purpose of that multiplexer board? Is it an optional board, maybe used for connecting the machine to the casino's computer network for data collection, progressive jackpot, player tracking, etc? In the photo 63mini posted of the board in his machine it doesn't look like it has a lot of connections/wires/cables going to it.

My guess is the machine or game software is looking for a comm connection that isn't being made and then gives that mux error. It isn't a fatal error that halts the machine but does display on screen so the casino tech can fix the missing connection. Older threads about this mention it might be related to the bill validator or to player tracking.

Check this out, beginning at the 4th post down:

Here are a couple more older discussions about the CEI mux error:

63mini- in those old discussions I saw it mentioned about something called the "Learn Mode" on the CEI machines. I guess it is sort of like a setup or preference settings in the machine software. Have you tried getting into Learn Mode and looking around to see if there are any settings to change that might eliminate the mux error? For example, if the bill validator is enabled in the settings but the machine does not actually have a bill validator?
