This is a conversion cable for connecting digital RGB (TTL level) from a D-sub9 connector 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 cable 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 can display 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 - GND x2 and Frame GND x2 Display side: Mini D-sub 15 - Each of the above, divided into RGB-GND x2 and SyncGND x2 Also, to increase the durability of the connection parts of both terminals, the solder joints and the coating of both terminals are fixed with a glue gun. The main unit terminal side has two fixing screws. The analog RGB cable side has female threads.
