  • ArcadeVGA outputs

    Hello. I'm trying to clear up a problem with my Mame cabinet which is a PC with an ArcadeVGA card, Jomac chassis and 29" TV tube. I'm not getting any picture to the TV, but using the ArcadeVGA's DVI output I have Windows running on a 17" monitor.

    I've tried plugging the 17" monitor into the ArcadeVGA's RGB output (15 pin VGA cable) and I don't get any picture. Is this because that output is CGA and therefore not displayable by the monitor?

    The full thread describing my problem is here if you have any other suggestions.

    Thanks in advance,
    Paul

    PS. There is beer/$$$ on offer to anyone who can help - I'm getting desperate!

    how is the monitor chassis connected to the Arcade VGA? via a Jpac or directly?

      It's connected directly. That is, RGB/black/white wires spliced into a standard VGA cable running to the ArcadeVGA. I've tried both the white and gray sync wires from the ArcadeVGA and it didn't make a difference.

      Would pictures help?

          isn't part of the JPAC circuitry the VGA Amplifier that takes the VGA signal from the standard 1v line level to the 4v used by most monitors?

          I know ultimarc sells this part (just the video amplifier) by itself, and believe you MAY need that (but im no authority).

          EDIT: re-read and found it wasnt working on a VGA monitor as well. Guess I am wrong, though it still may be a consideration for the arcade monitor.

            yes the amp may play a part.

              where do you live? If your gold coast/brisbane I could probably bring my JPAC around and see if that makes any difference to eliminate one potential issue.

                Thanks for the offer mate but I'm in Melbourne.

                Is there some way of testing the CGA output from the card, other than using the chassis or 17" monitor? Eg, using a multimeter somehow?

                  A couple of things..
                  1. If you plug directly you have to twist both horizontal and vertical sync wires together for the sync.
                  2. Without the caps added you will get a very dark picture.
                  3. Your VGA 15pin should work when you POST your system regardless of windows, if it does not then you problem is computer hardware based.
                  4. Verify your monitor setup is good... to do this I recommend finding someone local to you with a 48in1 gameboard as this uses standard PC 4pin molex power and has output for both VGA and CGA from the VGA port and the JAMMA harness.. You need to verify the monitors working.

                  Once all that is done its a metter of software setup

                    1. On the RGB adapter (output from ArcadeVGA) I have a white wire labeled "H/C" and a gray one labeled "V". Should these be twisted together and spliced into the white wire going to the chassis?

                    2. What do you mean by caps?

                    3. Are you saying I should be able to plug the 15 pin VGA (RGB) cable directly into my 17" monitor and get a picture? It only works on the DVI output, which as I understand it is correct.

                    4. Joey suggested this, but I don't know anybody in Melbourne with one of these. How much are they to buy? I have over $1000 in hardware doing nothing, what's another few dollars to get it working?

                    Cheers,
                    Paul

                        Gamedude, last night I twisted the white (H/C) and gray (V) wires together from the ArcadeVGA and spliced that into the white (sync) wire to the chassis. Still no result.

                        Surely somebody here has linked an ArcadeVGA to a chassis and TV tube?

                          Ok I've just verified that the chassis and tube are working fine by plugging in a game board (thanks again Joey).

                          When I plug the PC back in I'm still not getting any picture. Has anyone experienced this with an ArcadeVGA? If so, how did you solve it?

                          Also, the ArcadeVGA has primary and secondary displays labelled in the display properties in Windows. The secondary output (RGB) is currently going to the chassis. Is this correct?

                          Also I do not get the advanced properties page for the secondary display - is that normal?

                          Any other suggestions are welcome!

                          Thanks

                            I know SFA about the Arcade card but do you have to enable the second monitor in Windows? ie Right click it and select Attached.

                              I have my ArcadeVGA hooked up to my NANAO 15khz monitor with no problems. I am not sure if the dual res monitors are auto switching or manual switching between resolutions (Joey will know), but you could try setting the monitor & ArcadeVGA jumper to low res (15khz) and see what you get. Maybe the dual res needs the video amp but the single res doesn't??? As I recall removing a jumper will force 15khz. Gotta be worth a try. Also, try reinstalling the ArcadeVGA drivers, or if you had an ATI based card in the computer before, be sure to use the driver removal tool on Ultimarc's site and then reload. I'm in Sydney, so no local help from me I'm afraid. Oh, one more thing, I could not get picture from the CGA connection while ever the VGA was connected up. Try it with ONLY the CGA connected as well.
