answered my own question - the VGA out is simply a passthrough, by making a female VGA lead using pins 1,2,3,5,13,14 (r,g,b,Gnd,Sync-bridged)I was able to use the VGA lead with the 15Khz RGB standard going through it.
anyone know how to make these things save settings after they lose power? It would really suck if I had to recalibrate it every time I reboot the PC (which is supplying the +5VDC to the unit)
