3902 to 044 Conversion Monitor Questions

[Ash100]

Ok, I'll explain this the best way that I can.


I've got a lot of extra 3902 cabinets with 19 pin LCD monitors in them which are in much better condition than the few 044 cabinets that I have available to me.


So what I'm doing is converting the 3902 cabinets into 044's with Flashboards, etc.


I've swapped the backplane out but used all of the original 3902 wiring. Which was wired for 19 pin monitors. The 044 cabinets all have 25 pin LCD's. So, my question is this...


Will my 19 pin LCD's work in the current configuration or will I start burning stuff up if I start my power on checks?


I'm assuming that it is recommended to use the 25 pin wiring harness for the 044 machines and not the 19 pin?


I haven't had the chance to look at the schematics yet to tell the difference between the 2, other than the extra pins.


And of course I never think about any if this stuff until I'm at work and then can't look anyway.


So, chime in with your expert advise if you know off the top of your head, but honestly I'm thinking that a rewire would need to be done to keep the 19 pin harness in the machine.


Thank you,

The 19 pin configuration will work with 044, that is the way mine is running.  It has a 19 pin LCD monitor on it.  The only issue with some LCD's is the setting that needs to be changed for it to work right with 044.  I don't believe it applies to CRT monitors, only LCD's.  There's a thread somewhere about the ceronix LCD that displays weird colors when used with an 044 setup, and then you change a setting on the lcd menus to fix it.  In some cases, you have to flip a jumper setting on the AD board.

Thanks Rick,


That makes sense, but what I was mostly concerned about was the pinout of the 044 backplane compared to the 3902.


Maybe there's not any difference and nothing needs to be changed. Like I said, I'm using the original cabinet wiring harnesses and they all plug straight into the new backplane the exact same way they did on the old one.


So that being said, it's currently wired for a 19 pin connection at the monitor, so as long as the signals coming from the 044 backplane match the signal output pins of the 3902, we should be good?


Just wanted to be sure that I didn't need yo re-pin a harness somwhere.

There is no re-pinning of anything.  I've converted two 3902 cabinets to 044.  The only issue has been the LCD monitor.  My 17" cabinet's lcd automatically detected the change.  My bartop, I had to remove the monitor to get access to the A/D board and move the jumper to get it to work right.

Thanks again,


That's what I wanted to hear! Lol


Appreciate the help.

Ok,


Got everything installed in the cabinet and started my power on checks.


Have a known good 19 pin monitor, same one that originally came out of this particular cabinet. Also known good Mars MEI BV, also previously installed in cabinet.


All components worked as advertised in the 3902 configuration.


Swapped over the backplane only, it was an untested unit purchased for the conversion. MPU was pulled from a donor cabinet, working fine in it.


Upon powering up, I got the standard errors, turned key etc. Now I have a Touchscreen Failure message and a Bill Validator communication error.


This is kinda what I was afraid of. It seems that I'm missing the signals to power the BV and Touch Controller.


Any inputs would be appreciated.


See photos attached. Plus all leds on MPU are illuminated, if that means anything.


I can't clear RAM and apply Keychip until the touchscreen issue is solved.


Thanks, Curtis ash100

Those are netplex devices.  Are you sure you didn't reverse the senet and netplex plugs mixed up?  One of the issues with these machines is that netplex is a single bus, and any failure along the line, brings the entire netplex bus down.  Like I mentioned before all cabinets I have transitioned never had any issues with pinouts, power, etc.  The ONLY issue is the monitor sync.  If you are having issues, you pugged in something the wrong way.  Unplug the senet and netplex plugs and make sure you have the correct connections (the connectors should be labeled with a PXX label), match those labels with your old mainboard and take note which one is senet and which one is netplex (the connectors look the same) then go back and look at your connections.  You can test the validator to see if the error goes out by removing the netplex plugs from the backplane.  The touchscreen also has it's own connector, so removing the netplex pug from the backplane should isolate just those two devices.

Reseat the 044 board, make sure it's slid in all the way. Check for bent pins.

Thanks Mark and Rick.


Pulled MPU, inspected pins and verified the connections on the backplane. All Plug numbers match the Jack numbers on motherboard, so everything is plugged in correctly.


Swapped the Flashboard over to a different MPU, solved the BV and Touchscreen errors. Machine hangs up at verify all options box once it booted.


Checked items in the menu that I could access without a keychip process. Got a BV CRC Mismatch that I couldn't clear. Restarted the machines and now it's hung up on Initializing the Sysyem.


Been that way for 10 minutes.


I'll keep at it.


Thanks again.

If you swapped mpu's you need to re-key and clear.  Also clearing BV CRC's is done through the peripheral menu, there should be a clear crc in the bv settings.

[Ash100]

Oh boy, I've about had it with this thing today!


Put in the Keychip, now the touchscreen won't work again.


Uggh.


Update, even tried a different monitor.
What's up with that? Is it too hot maybe? I'm in my shop in Georgia, and there's no A/C.

Be sure your MPU fan is working. 044 boards will get hot quick without the fan. There's no need to remove the boot to key chip it if you use a 39 boot.

[Ash100]

Tried 2 MPUs, Boot 39 and Key28,
Can get to the menu, but touchscreen won't respond.


Can't RAM clear and start anything if that's not working.


Checked all fans, they're spinning freely.


Completely at a loss at this point.


Thanks for the suggestions.

same or different backplane?


have you also removed the green battery and u24 (if US software) http://newlifegames.com/nlg/index.php?topic=4092.0

Finally got the machine cleared and set up.


Apparently it was a heat issue? Was working on it out in my shop, which is not air conditioned, so I moved the machine inside and let everything cool down. Touchscreen came back and works now.


Georgia heat in the summertime sucks!


Thanks for all of the great advice.
