I have a customer machine, Revenge from Mars, with NuCore 2.0, that when you press Enter to start test mode, the game reboots. No access to Adjustments, Diagnostics, or anything of the like. Help.

can you press both middle buttons to enter nucore menu?

#3 5 years ago

I'm with you on this one. How the heck do you get to the diagnostics/test menu? Enter just resets the machine. +/- hit together enters the menus but there is no diag option...?

#4 5 years ago

Does enter reset the machine or reset the nucore software? Exactly what happens with some detail?

#5 5 years ago

I will check on it today and post back soon as I can. I still haven't set it up at my house yet.

Ok so here's what I got. I pick up a RFM recently with Nucore and 19" LCD screen. Sweet game so far. But i cannot figure out how to get to the main menus like the diagnostics and adjustments. When you open the coin door, the alert comes on. It says hit + and - together to enter menus. All you get there are the Nucore menus (see below). This isn't what I'm looking for. When you hit enter, it just seems to reboot the game/Nucore.

Does anybody out there have a Nucore RFM and know how to get to the diagnostics/adjustments menu???

Hitting enter should take you into WMS diags. Shoot a close up picture of the USB board that clearly shows jumper settings.

Hitting enter from this screen or hitting enter right after you open the coin door? Hitting enter here and going into game options just let's you choose whether it's RFM or SWE1. Hitting enter after opening the coin door just resets the game.

I can take a picture of the USB board. Where is it located?

USB board should be mounted inside the case, assuming we built it. Could be anywhere if the old owner built it. Follow the USB chord coming out of the computer port on the side.

Hitting enter right after you open the coin door should go into diags.

#10 5 years ago

I'm assuming we are talking about the computer in the head? There is a USB cable that is plugged in and then goes inside the case. So I need to remove the PC and open that baby up?

Yeah hitting enter after opening the coin door just resets the nucore. Is there some sort of a jumper setting that would cause this?

Step by step. Trying to eliminate Nucore as the issue. I'm guessing it's not just want to make sure.

Ok sounds good. I will try and check that out tonight. I'll post back when I do. Thanks for all of the help!

#13 5 years ago

OPening the coindoor and hitting enter should take you to diagnostics

pressing + and - together takes you to nucore options but these is no diagnostics there.

#14 5 years ago

Ok. I didn't have time to get to the USB board. But here is a quick video to show what's going on. Thanks for your input.

#15 5 years ago

I believe the original system reboots on a slam tilt. Try the slam tilt switch and see what it does.

#16 5 years ago

Ok that doesn't reboot. It crashes the nucore app and restarts it. Curious. What happens if you select Star Wars as a game instead and attempt to enter the menu there? Does anyone know if nucore has any logs? I can enter the diags fine on my Rfm so its not a generic nucore issue.

A slam tilt signals a reboot as I recall on the original machine. When we detect a reboot signal we reboot Nucore. Don't select Star Wars. As I recall forcing one of the games incorrectly makes bad things happen.

Well I took a look at my slam tilt on the coin door before work today. The contacts are not touching. Is that the way it is supposed to be? Are they normally open or normally closed? I've never really payed attention to them. Also, the one in the bottom of the cab, where a shaker would sit, that one is open too (is that a slam tilt switch as well?). If these are supposed to be normally open, they appear to be just fine. I can still test them with a meter to make sure they aren't shorted together (wire pinched somewhere). With a meter I should read "OL" (no continuity)?

I believe you are correct. When this happens, it restarts the game much quicker than when originally turning the game on. It would make sense that it's just restarting the NuCore app. I'm not sure I want to try selecting SWE1...I don't want to mess anything up.

Anyone have any idea what I can test next? Are there dipswitch settings somewhere? Do I need to look at that USB board for the jumper settings (i have no idea what those mean/are)?

I've got about 5 hours of free time tonight to mess around with this thing.

#19 5 years ago

Bump. Anyone ever run into this?

#20 5 years ago

Here are some pics of the display when I hit the enter button on the coin door and it resets.

The board is set correctly. Open the coin door and trigger the slam tilt switch

Ok thanks. I will do that tonight and post back.

#24 5 years ago

Hey just a thought. I've heard that you can hook up a keyboard to these machines and enter the Diag/Adjust menu. Should I try doing that too? How/where do you hook up a keyboard to it?

Also, what is that plug by the coindoor open switch?

You haven't reported back on what chessiv asked you to do yet.

Hi I am the new owner of this rfm and have done a few more tests..
The slam tilt switches on the door and the cabinet are not registering. The plumb bob does work and all the other switches and game appears to work.. I'm thinking a board issue but need some guidance on where to begin.. Any help would be much appreciated. Or maybe a pic of the coin door/slam tilt switches and door button wiring may help.. This is a re-import with one coin slot (switch works) and a bill exchanger.

#27 5 years ago

Morning bump. Any thoughts? Thanks everyone!

#28 5 years ago

I had a RFM with Nucore, and it was doing this exact same thing.
We had even sent it back to them once, and got it back with the same problem.
Never got it figured out, and sold the game because it was worthless for tournament play without being able to get into test.
I hope you figure it out, and please post the fix if you do. I still know who has the game.
BTW, we also had tried reloading the software, with no change. I'm pretty sure that's all they did when we sent it to them as well.

#29 5 years ago
Quoted from DNO:

We reload software, if necessary, run hardware tests on the USB board and run a smoke test on a real machine, which your system would have passed before we sent it back. I tried to work with the original owner of this machine and I have tried to help drumasauras. I really think this is a physical issue with the machine. He could send his Nucore unit to us for testing but I'm 99% positive it will pass all tests.

#30 5 years ago

Well I am glad to hear I am not the only one in this boat, but it doesn't instill confidence that there has been no resolution. I plan on seeing this fix through as these things drive me nuts if I can't figure it out.

I am starting to also believe the coin door wiring or board are to blame. I pulled the Nucore out last night and checked cables and connections and all appears to be functioning.

The slam tilt switches and enter button are not on the same switch row but there seems to be a correlation as when the enter switch is pressed the game almost seems to reset like its been slam tilted..? Although I don't know specifically how RFM w Nucore reacts to a slam tilt..

The enter button has a black/blue stripe wire and two blacks going to the other pin on the switch. The switches seem to work fine when I am in the Nucore Menu (press the two red buttons simultaneously) - I can scroll and select items in this menu with the enter button just fine? Another reason I don't think Nucore is the issue..

Can someone confirm how a slam tilt appears on a RFM with Nucore? Will the system do a quick reboot like it is doing when I hit enter?

And any thoughts on testing these switches through a jumper would help. thanks.

Also does it matter which socket the 9 pin connector is connected to on the main board? see pic.

Afternoon bump.. Any RFM/Pinball 2000 experts that can lend a hand? thanks.

A slam tilt does indeed cause the reset that you are seeing when you press the enter button. The previous owner posted a picture of the screen and I verified this is the case.

#33 5 years ago

Thanks chessiv. I am at a loss as I traced the black/blue wire coming from the menu button to the PCB and it appears to be pinned correctly plus the this button works fine when in the Nucore menu..

Anyone have thoughts why the enter button would trigger a slam tilt and when the slam tilt is activated, the game does nothing? Thanks!

#34 5 years ago

Ok, I was curious and looked this up:

http://www.chucksarcade.com/grabs/2014-09-26_154802.png

That's a snippet of the schematic for the coin door interface board. Notice the enter button switch wiring is right next to the slam tilt. Get a good copy of the manual if you don't have one. I grabbed this off of ipdb although its lower res. Pull the coin door interface board out and test connections with a continuity tester on the board and on the cables. You may find something there.

#35 5 years ago

Thanks! I had the board off before but failed to check continuity between these pins etc.. I will check tonight and report back.

Thanks for taking the time to dig around and yes, I do need a better copy of the manual.. the one I have looks worse than the link you provided. Thanks again.

#36 5 years ago

Well I checked the coin door interface board and there were no issues to be found with traces/continuity etc..

I decided to see if the jukebox in Nucore worked and was able to load a .mp3 but Nucore wouldn't play the song..? Maybe there Nucore needs to be re loaded..?

#37 5 years ago

Make sure the jukebox is enabled in the Nucore menu. We'd be glad the check out the machine for you. There is a bench fee but we will go through and verify everything is working well and if it's not correct it. But I don't believe it is a Nucore issue. I could be wrong. I just really think this is a driver board or cabling issue. Let us know if you want to send it to us.

#38 5 years ago

Juke box was enabled and the song would appear on the screen but no audio..?

#39 5 years ago

Did you adjust the volume up? AFAIR it's the action buttons

#40 5 years ago

So you can use the info Borygard posted to trouble shoot your switch matrix. He also shows how to enter diags without the board connectors attached and using a jumper wire. I would definitely try that. https://pinside.com/pinball/forum/topic/p2k-swep1-switch-matrix-problem. 3rd or 4th post.

#41 5 years ago

Chessiv - I tried the action buttons but they were not responding - they work during game play.

Thanks markmon, I will need to look into this tomorrow if I can find a moment.

#42 5 years ago

My apologies for not getting on this quicker, I had a very hectic week...

Anyway, I was able to test with the jumper wire on J114 pin 13 tonight and the same reset occurred... still not able to get into the menu..

One observation about the J114 plug, the schematic says that pin 7 is Gry-Yel +12v DC and pin 14 is Blk Ground... There are no wires to be found for these spaces on the plug.. I don't think this is the issue since when I grounded J114 pin 13 as mentioned above, the game acted the same as if I hit the enter button.. but thought I would throw it out there..

Anything else i can test? Thanks for the help thus far!!

Bump for an old post. I am kind of at a standstill on the menu issue. As stated in my earlier post, I jumped the j114 - 13 pin to ground and the game still reset - not able to access the menu.

I know know that the wiring for the enter button is not the issue, but I am still confused if this test definitively tells me its a board issue vs Nucore?

The slam tilt switches on the coin door and cabinet still don't do anything btw.. I was thinking about testing this directly from the board by jumping J113 - 1 to ground, but wasn't sure if I could test the slam tilt the same way I tested the enter button? Not sure if it would shed more light on the issue either.. Thoughts..

#44 5 years ago

Ya I would debug this as if it were a board issue not Nucore related.

#45 5 years ago

The diagnostics menu issue I was having has been resolved!

After confirming the board and wiring were ok, I sent my Nucore to Don (with Nucore) and he was able to figure out the issue. I am not a computer guy but basically it was a corrupt file that ended up being stored which wouldn't allow the game to go into diagnostics.

So if anyone is having this same issue with a Nucore game, give Don a shout and he should be able to help out. Thanks to everyone for the insight and help, especially Don for being dedicated to figuring this one out.

#46 5 years ago

Awesome to hear you got this resolved! You have more patience than me, that's for sure.

Thanks guys! This was a tough one to figure out. Thankfully I received help from fellow pinsiders and support from the Nucore guys. Sounded like there were a few others stumped by this issue so hopefully it helps others.
