Hello, Working with a client that ordered a new display for his Batman Forever. Upon checking the pinouts the 12vdc measures at 18vdc at the connector. This 18 vdc comes (purple wire) from the lamp matrix area. As the display calls for 12vdc am I safe to plug this in? Or is the display capable of running on 18vdc as well.? Thanks in advance! JR

Doesn't he have the old display? You can see what it measures with the old one connected.

I replaced a large DMD on a Frankenstein.

It most likely will not be plug and play. The molex connector on the DMD should list what the voltages should be (it's a little white sticker on the top of the connector soldered to the DMD). If you compare those voltages to the molex connector on your old display (again, look for that little white sticker) the voltages will probably be different (I think I had a Cherry display and replaced that with a Babcock).

If your DMD doesn't have the little white sticker on the molex connector, you will have to find the schematics. The old DMD I replaced didn't have the sticker (the new DMD did), but the display came with the schematics and told me what the voltages should be. I know Batman Forever manuals are pretty much non-existent, but the Frankenstein manual should have all the information you need for this. Here is the manual:

http://mirror2.ipdb.org/files/947/Sega_1995_Mary_Shelley_s_Frankenstein_English_Manual_pages_67_93_which_are_the_schematics_OCR_searchable.pdf

Page 21 shows the Babcock display. "P1 Power" shows what you need, 12V, Gnd, Gnd, N/C (Not Connected). I took two pictures to give you an idea of what I did. Looks like I replaced mine with a Babcock display. They are probably the only large plasma DMDs left at this point.

Also note that in the manual schematics for other displays can be found (I think the page before is the Cherry display).

Hello, thanks so much . Just one question . My 12 volt blue wire is reading 18vdc. Could this be an issue when hooking up the new display? Dont want to overpower and blow 400 If you would be so kind could you please measure that blue wire voltage? (thats spliced into the red? ) Thanks in advance! JR

You said you are replacing your Babcock with a Vishay from pinball life. I don't see a Large Vishay DMD for sale. Can you take some pictures? Of the molex connector on the display and the connector coming into the display? Some pictures of the actual display perhaps?

The purple (blue?) should be 18V (at least on Frankenstein). What voltages does the Vishay DMD require?

Here we go. Schematic for the Vishay large dmd is here:

Looks like Pin 1 requires a min. of 10v, max of 28v. Pins 2 and 3 are ground. And Pin 4 is not connected.
