H! My old Covid RGBS interface has broken. But I do have a similar old Barco RGBS interface. The problem is the pinning is not the same. When I wrote Barco they answered: "The mentioned interface is a dedicated VGA interface and the connections are made as standard VGA ." I soldered a cable according to this site: http://www.hardwarebook.net/cable/av/9to15vga.html That is: 1 1 2 2 3 3 11 11 13 13 14 14 I get the tubes to lighten but there is no sync. How should I solder the cable to get a proper sync signal?
