What it does<\/strong><\/td>\n<\/tr>\n
The Ultracade Universal Video Converter, or UVC <\/strong>for short, can convert a high res video signal into an arcade monitor compatible RGBS signal. In 15kHz or in 24kHz. There are other ways of hooking up a high res source to an arcade cabinet like this, but no other can output to 24kHz (AFAIK). <\/p>\n

From the manual:<\/p>\n

” <\/strong>This is a very simple board that has only one function, to allow the display of PC based games on older arcade style monitors. The board needs to be an external device that requires no modification to the software running on the PC. It will handle one of three input resolutions (1024×768, 800×600 or 640×480) with a vertical refresh rate of 60Hz and output to one of two user selectable output modes (640×240@15.72KHz) or (640×384@24.9KHz) The coin-op monitors are RGB non-interlaced and run at 60Hz. The Input of the board will be a DBH-15 VGA analogue VGA connector and the output is a 0.156\u201d molex connector with pins for R, G, B, Ground and Syncs.<\/p>\n

How it looks<\/strong><\/td>\n<\/tr>\n
All example pictures are NANAO MS9 (EGRET II, New Astro City, etc). The best dual-sync monitor (15\/24kHz) ever made in my (and many other peoples) opinion. <\/p>\n

Note: I used a 3rd party 360 VGA cable at the time of taking these, but have since upgraded to an official product with noticeable results. There’s a slight ghost effect on all pure white objects that’s completely gone once I switched to a Microsoft cable.<\/p>\n

Next, some comparison shots between an UVC and an Extron Emotia that I had before finding out about the UVC. The Extron scan converters are superb, but can’t except higher input resolutions than 480p and can only output at 15kHz.<\/p>\n

Troubleshooting<\/strong><\/td>\n<\/tr>\n
The uVC should work right out of the box. If you are having trouble getting an image, refer to the section below that applies. <\/p>\n

No image on the monitor at all:
\n\u00b7 Verify that the PCB is powered (all 4 LEDs near the fuses illuminated)
\n\u00b7 Verify that the PCB is running (at least one of the LEDs near the output Molex (J7) is illuminated)
\n\u00b7 Verify that the splash screen is enabled with DIP switch 1
\n\u00b7 Verify that the monitor is powered
\n\u00b7 Verify that you have the proper video cable attached correctly to the monitor<\/p>\n

NOTE: if you have a v00 or v01 PCB (firmware 1.xx), make sure that the Hsync and GND pins are correctly connected; they changed on the v02 PCBs and later (firmware 2.xx and later)<\/p>\n

Monitor always displays the default \u201csplash\u201d screen
\n\u00b7 Ensure the input has a vertical refresh rate of 60Hz
\n\u00b7 Ensure the input is either VGA (640×480), SVGA (800×600) or XGA (1024×768)
\n\u00b7 If the splash screen says there is no input detected, check there is actual input data<\/p>\n

Image on the monitor keeps cycling:
\n\u00b7 Verify that you have the proper output mode with DIP switch 3
\n\u00b7 Change the sync signals from composite to separate (or vice versa) with DIP switch 8
\n\u00b7 Change the sync signals from positive to negative (or vice versa) with DIP switches 6 and 7<\/p>\n

Image on monitor is stable but top of screen is displayed on bottom, or bottom of screen is \u201ctorn\u201d
\n\u00b7 Change the input to output delay with DIP switch 2<\/p>\n

Image is good, but intermittently goes back to the \u201csplash\u201d screen
\n\u00b7 Some consoles have been found to have unstable synchronization; ensure you have v2.1 of the firmware or later (version is shown on splash screen)<\/p>\n

\u00b7 If you’re using a computer as your source, some versions of Windows (Vista, maybe others) are tricky to get into a compatible video mode<\/p>\n

\u00b7 Using a video card with a DVI output using a DVI->VGA adapter might not always work<\/td>\n<\/tr>\n

Important notes<\/strong><\/td>\n<\/tr>\n
The pinouts for the video output (J7) were different in prototype PCBs (version 00). In all subsequent PCBs produced, the output video matches the reverse of the pinouts on most monitors (R,G,B,Gnd,Vsync,C\/Hsync). <\/p>\n

The version of the PCB is given on the PCB serial number starting 990uVCxxxxxxxxx; the last two digits after the final dash are the PCB version.<\/p>\n

If you have a uVC with PCB version 00, please note that you must swap the C\/H Sync and Video Ground pins on the cable to your arcade monitor.<\/p>\n

Some ”unofficial” stuff<\/strong><\/td>\n<\/tr>\n
Using an XBox 360 as a source, you can get the UVC to accept the below resolutions.
\nI can’t think of a really good use of these, but perhaps for some odd 360 game it’ll come in handy : <\/p>\n

848×480<\/strong> (this mode is widescreen, so the 360 can’t be set to full screen)
\n1280×720<\/strong> (this mode is widescreen, so the 360 can’t be set to full screen)<\/p>\n

Note: I’ve only tested the above two modes in 24kHz, not sure how they will handled in 15kHz but they should work.<\/td>\n<\/tr>\n

\n<td>The uVC should work right out of the box. If you are having trouble getting an image, refer to the section below that applies.<\/p>\n

No image on the monitor at all:
\n\u00b7 Verify that the PCB is powered (all 4 LEDs near the fuses illuminated)
\n\u00b7 Verify that the PCB is running (at least one of the LEDs near the output Molex (J7) is illuminated)
\n\u00b7 Verify that the splash screen is enabled with DIP switch 1
\n\u00b7 Verify that the monitor is powered
\n\u00b7 Verify that you have the proper video cable attached correctly to the monitor<\/p>\n

NOTE:\u00a0\u00a0 if you have a v00 or v01 PCB\u00a0 (firmware 1.xx), make sure that the Hsync\u00a0\u00a0 and GND pins are correctly\u00a0 connected; they changed on the v02 PCBs and\u00a0\u00a0 later (firmware 2.xx and\u00a0 later)<\/p>\n

Monitor always displays the default \u201csplash\u201d screen
\n\u00b7 Ensure the input has a vertical refresh rate of 60Hz
\n\u00b7 Ensure the input is either VGA (640×480), SVGA (800×600) or XGA (1024×768)
\n\u00b7 If the splash screen says there is no input detected, check there is actual input data<\/p>\n

Image on the monitor keeps cycling:
\n\u00b7 Verify that you have the proper output mode with DIP switch 3
\n\u00b7 Change the sync signals from composite to separate (or vice versa) with DIP switch 8
\n\u00b7 Change the sync signals from positive to negative (or vice versa) with DIP switches 6 and 7<\/p>\n

Image on monitor is stable but top of screen is displayed on bottom, or bottom of screen is \u201ctorn\u201d
\n\u00b7 Change the input to output delay with DIP switch 2<\/p>\n

Image is good, but intermittently goes back to the \u201csplash\u201d screen
\n\u00b7\u00a0\u00a0 Some consoles have been found to have unstable\u00a0 synchronization; ensure\u00a0\u00a0 you have v2.1 of the firmware or later\u00a0 (version is shown on splash\u00a0\u00a0 screen)<\/p>\n

\u00b7 If you’re using a computer as your source, some\u00a0\u00a0 versions of\u00a0 Windows (Vista, maybe others) are tricky to get into a\u00a0\u00a0 compatible\u00a0 video mode<\/p>\n

\n<td>The pinouts for the video\u00a0 output (J7) were different in prototype PCBs\u00a0\u00a0 (version 00). In all\u00a0 subsequent PCBs produced, the output video matches\u00a0\u00a0 the reverse of the\u00a0 pinouts on most monitors (R,G,B,Gnd,Vsync,C\/Hsync).<\/p>\n

The version of the PCB is given on the PCB serial number starting\u00a0\u00a0\u00a0 990uVCxxxxxxxxx; the last two digits after the final dash are the PCB\u00a0\u00a0\u00a0 version.<\/p>\n

If you have a uVC with PCB version 00, please note that you\u00a0\u00a0 must\u00a0 swap the C\/H Sync and Video Ground pins on the cable to your arcade\u00a0\u00a0\u00a0 monitor.<\/p>\n
