This is a conversion cable for connecting digital RGB (TTL level) from a D-sub9 to a compatible external display's mini D-sub15 connector. (It has a simple structure with only pin assignment conversion and resistors.) This 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 Original FM77AV-1/2 (models with RGB21 connector also) Compatible displays: (It takes effort to find these...) Mini D-sub15 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 on the internet, such as those where the display is displayed but adjustments are needed on the display side.) Please find a combination that matches the PC and display and has good compatibility. 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 not attached to the analog RGB cable side.
