I just bought a used WG 9200 and it doesn't have a standard Plug. I have an old WG 19 inch(don't know the model off hand) that connects to my arcade Cabinet and I then plugin in my standard outlet plug. If that makes sense? I believe it is an Isolation transformer.
How do I go about plugging in this WG 9200 without the standard plug? It has a two prong and a three prong connection on the Monitors board.

For my old monitor I have the Black and White wires as shown here
(http://i88.photobucket.com/albums/k182/savj14/photo1.jpg)
The Black/White wires then tie into one connector, and that connector clips on to a second connector leading to my Transformer. Shown below
(http://i88.photobucket.com/albums/k182/savj14/photo2.jpg)
I can then simply Plugin my standard Plugin and the Monitor powers on as it should.
Can I take the Black/White wires from the WG 9200 and do the same thing?
-
Anyone out there??
Ok so the WG 9200 has a 2 pin and a 3 pin on the video board. The 2 pin connector is already connected. But how do I go about connecting the 3 pin?
The connector coming from my Iso transformer has only 2 wires as seen in the pics above. I am so confused. I thought the WG 9200 was plug and play?
-
I thought these Monitors don't need an Isolation Transformer? Wouldn't I just need something like this:

If so where do I go about getting something like this? Or is it something I can make on my own?
The guy I bought the monitor from said I needed an Iso, or I could ruin the monitor.

No isolation transformer is needed according to the Wells Gardner site, http://wildcatting.com/PD/Spec/D9200_27_33.PD (http://wildcatting.com/PD/Spec/D9200_27_33.PD). This page http://www.wildcatting.com/products/details.asp?cat=4&iceboat=24&=WGM2792-U0TS08E (http://www.wildcatting.com/products/details.asp?cat=4&iceboat=24&=WGM2792-U0TS08E) has the ac power cord you need you should be able to order this directly from Wells Gardner or Happ.
-
I recently got the same monitor and it did not come with the cable. I took a standard computer AC cord and clipped off the end that plugs into the power supply. I found a matching 4 hole connector plug (only 3 slots are used) at Fry's and connected the green, white and black cables to the correct plugs.
It works just fine and is the same thing that you would buy from Wells Gardner.

Call the Wells-Gardner parts department. Order part number 038A8059-000 AC power dongle adapter (3 pin to 2 pin, pictured on their website). One end plugs into the monitor and the other ends plugs right into the existing two pin connector in your cabinet.
They also sell a straight power cord for it: # 038A7927-000 AC Power Cord

Thanks for the info guys. I might try and hack a cable first. Do I need a connector plug or can I just twist the wires on the boards 3 pins?
How do I know which pins the green, white and black cables should go?
Also, I did something stupid while playing with this last night. Instead of being patient and asking here first, I did the following:
I took the two pin connector(the one that should be connected to the monitor board), cut it, twisted those to a connector. Plugged that connector into the connector that goes to my ISO. I then tried to power on the monitor. It made a little noise but didn't appear to do much else. Did I just fry my monitor?
-
Ok so I hacked the cable and was able to power the monitor on. When I connected it to my PC in Windows via the VGA cable the screen is just all grey and in a small trapezoid shape.
I selected 640x480 and also tried 640x480 interlaced.....still cannot see much of anything in Windows
Any suggestions or ideas?
-
I haven't played with any of the controls in the back yet, so it could be something there. But it almost sounds like it could also just be a resolution issue...It definitely syncs though
I dunno
-
Turns out there is a EGA/CGA connection and a VGA connection. I switched the connector to VGA and it worked. Not sure what the EGA/CGA connector is even for. Anyone know?
Everything looks good, buy I am struggling to the colors and brightness the way I'd like it. Anyone with the monitor care to share their settings? What number do you have setup for Contrast, Brightness, R, B, G, etc? Do you have the Screen setting in the back turned up quite a bit?
Also, I cannot seem to get games in MAME to fill the screen completely. There are noticeable black borders on every game. I am using Powerstrip and added custom resolutions. I then tried to use the monitors controls to increase the Vertical size but it is maxed out at 255.
If I buy the ArcadeVGA will all of the games fill the screen completely?
-
Turn your monitor on and let it warm up well before you try to adjust any setting. You should have the monitor on for a good 30 minutes before you try to play with colors, contrast, geometry etc.
-
Ok, thanks for that info.
As a general rule of thumb, what should the Screen control, R,G,B,contrast,brightness be set at?
Right now I have the screen control somewhat low, everything else is set to the highest setting. I assume that is not correct? The monitor just doesn't seem as bright as I would have expected.
-

It's for EGA/CGA video signal resolutions. ;)

Are you referring to the SCREEN control on the flyback itself, or is there an OSD option for that?
If you are talking about the screen control on the flyback....... you should adjust it with NO video going to the monitor to start with.
Turn it down, remove your video cable, then adjust it up until the screen starts to turn gray, turn it back down until the screen just turns black. Now plug in your video cable and try adjusting everything else again.
-
So should the pin be in the EGA/CGA or the VGA connector? Since it is being used for MAME I'll need it for EGA/CGA games mostly. I had the pin in EGA/VGA but the screen was just all grey. I switched it to VGA and it works. But does this mean I am only getting VGA resolutions? That would defeat the purpose of trying to get arcade resolutions right?
As far as the screen control, yes it is the one on the Flyback. I will try what you suggested and see how that works out for me.
Should the brightness and contrast be somewhat high? Or even all the way up?

You would have to make certain your resolutions are set correctly for CGA or EGA and then try that. I'm not really familiar with the 9200 to know it's options or how each connector is intended to be used.
Should the brightness and contrast be somewhat high? Or even all the way up?
I typically set both of those halfway and then adjust the screen control and then go from there by adjusting each color and then maybe the brightness and contrast ab it as well.
Try this Nokia Monitor Test while adjusting your monitor.

Is anyone familiar with this monitor and how the EGA/VGA and VGA connectors on the MB work?
-
Ok I found the schematics for this monitor. If I am looking at this correctly, which I hope that I am, it seems if I am using a VGA cable to hook this up I have to have the connector on VGA. And for an EGA/CGA hookup I would need to use the EGA/CGA connector
That would make since, when I had the connector on EGA/CGA(didn't realize it at the time) and tried to connect using my VGA cable the screen was all grey.
But I guess that still doesn't really tell me if I can still use EGA/CGA resolutions if the selector is on VGA :-\
-
Any reason why in both Windows and in MAME the screen is not filled completely? There is a good 4-5 inches of black borders on the top and bottom.
I am running 640x480 in Windows. MAME resolutions vary by game. But I used Powerstrip to add custom resolutions. MK for example is using 800x256. Which should fill the screen completely, or at least very close.
Any thoughts? I ordered an ArcadeVGA, does anyone have a WG 9200 and the AVGA? Do you get games to fill the screen?

.....monitor wiki.........

Experiment with your refresh rate a little and see what it does then.
Graphics modes:
CGA: 640 X 200
EGA: 640 X 400
VGA: 640 X 480
Video bandwidth:
25 MHz typ.

I was just taking a look at the schematics I attached, and noticed the following:
VR402 - SUB-HORIZ.SIZE
VR901 - ADJH.V. ADJ. (FACTORY SEALED)
VR401 - SUB-BRD ADJ
VR101 - RASTER ROTATION
Are these adjustments I can tweak? I'm not at home right now, otherwise I'd take a look myself. What do each of these do?
-
I assume this is a D9200? If you aren't sure what resolution that the monitor is actually displaying, bring up the on screen display. It should have a horizontal frequency listed somewhere. Anything around 15khz-16khz is CGA, ~25khz is EGA and ~31khz is VGA, ~38khz is SVGA (800x600). I'm pretty sure that monitor does not require any physical jumpers to alternate between those resolutions, so I'm not sure what the jumper you mentioned is for. That would defeat the whole point of a digital multisync if you have to swap jumpers.
-
Yes it is a D9200. I'm waiting for my AVGA card to come this week, so using this card will probably solve my resolutions issues. I think I messed my settings up on my current ATI card.
I was just thinking if these adjustments I listed can help out with the screen size, I'd try it out.
The only other issue I have with this monitor is that it is not as bright as I think it should be. It has more of a "grey" or dull look. I played with the screen control, focus, etc. for hours. The only way I can get it to look decent is by turning the brightness and contrast all the way up. It looks a little blurry though because the contrast is so high.
I haven't entered into the Factory Menu yet, does anyone know if this has extra features to help brightness?
If not what needs to be done to the monitor to get the brightness back to how it should be? Cap Kit?
-
Just installed the AVGA........the monitor looks the exact same.
So what is most likely the issue with this thing?
Dull/Greyish screen(not very bright) and the screen does not fill completely Vertically.
-
anyone out there?
-
Um.....still waiting on you to post some resolution and refresh rate experimentation results.
Not just the 640x480, etc..... but the refresh rates as well.

I can provide these later today. But with the ArcadeVGA I shouldn't have to worry about any of this right?
From Booting until I get into Windows, to playing any game in MAME the screen will not fill completely Vertically. I even adjusted the H.V. Adjustment Pot on the board and it only fills the screen so far.
-

Here you go
640X480 = 31.5Khz/60Hz
384x288 = 15.7Khz/51Hz
400x256 = 15.6Khz/53Hz

FYI, on most of these montors, the only difference between the EGA/CGA input and the VGA input is how it handles video signal levels and termination. Both inputs will usually accept the full range of scanrates supported by the monitor. Since PC video cards output 0.7Vpp signals into 75 Ohms no matter what timings they are outputting, just leave it on the "VGA" input, even if you're feeding it CGA or EGA timings.
Also, don't go adjusting that HV adjust pot without knowing what you're doing. That adjusts the high voltage (anode) output from the flyback. Messing with that will affect size somewhat, but that is NOT a geometry adjustment (!!).
This monitor likely has a "factory" or "service" mode. You may be able to adjust vertical size in there in order to get it to fill the screen. Those controls usually have much more range than the "user" controls. Just be sure to write down all the original settings as there's usually no way to "restore" them if you mess them up.
Not familiar with the D9200, but some monitors also have an analog "coarse" vertical size adjustment pot somewhere on the deflection ("chassis") board. Take a look to see if yours has one.
-
I tried using the Factory Mode but it had no affect on the vertical size. The maximum is at 255 and I cannot higher than that. I also didn't see a Vertical pot anywhere. Does anyone know if there is one on this monitor?
-
anyone???

Please lock this thread.
I'm selling this POS.....waste of money

Dude, try one more thing. Scrap powerstrip, and load soft15khz. JUST 15/25/31KHZ. Do not load usermodes or worry about them. Set desktop at 640x840. Reboot. Call up your graphics card contol panel, and find something like 'screen resolution' and go through the lower ones. Your desktop will remain, but the resolution will change. It'll probly ask you if you wanna keep it. If you can see that, click 'yes'. (I suggest this method first, because if it goes out of sync or beyond the monitor's scan capability, within fifteen seconds it'll switch back to what it was.)
If you can't figure that out, try this: get this (http://ultimarc.com/quickres.exe), click on it. Notice it loads in the task bar tray, lower-right. Click on that, and select different resolutions same as above.
Now, if you indeed can't get the image to fill the screen with only the OSD, obviously something's wrong.
