This is a conversion cable for connecting digital RGB (TTL level) from a D-sub9 to a compatible external display's mini D-sub 15-pin connector. (It has a simple structure with only pin assignment conversion and resistors.) This cable is used between the PC and a general-purpose analog RGB cable from the display. Therefore, it is short. Please prepare your own male-to-male general-purpose analog display cable. (The blue one often included when you purchase a display) Compatible Models: D-sub9 video output Fujitsu FM-77D1/D2 L4/L2 First generation FM77AV-1/2 (models with RGB21 connector also) Compatible Displays: (Finding these is a hassle...) Mini D-sub 15-pin 3-row connector (commonly called a VGA connector) that supports a horizontal sync frequency of 15kHz. (L4: 400-line set II 24kHz) (There seems to be a lot of information online, such as displays that will show an image but require adjustments on the display side.) Please find a compatible combination of PC and display that suits your needs. A total of 4 wires are used for GND PC side D-sub9 GNDx2 and Frame GNDx2 Display side Mini D-sub15 Each of the above, one each, divided into RGB-GNDx2 SyncGNDx2 Also, to increase the durability of the connection parts of both terminals, the solder part to the coating of both terminals is fixed with a glue gun. Two fixing screws are attached to the main unit terminal side. Female screws are also attached to the analog RGB cable side.
