电子D-SUB介绍与相关规格（国外英文资料） D - SUB is introduced: The d-sub is short for d-subminiature, an interface shape and structure that was invented by the ICC in 1952. Because at the time, the interface was small, it was named subminiature. D - sub contain several subclasses, such as DB25, belong to the first letter D D - sub, the second letter B is to describe the size of the interface, and the back of the Numbers (pin number) corresponding to (A = 15 needle, B = 25 needles, C = 37 needle, D = 50 needle, E = 9 needles). Each interface is split between the common head (plug) and the parent (socket). ????? USES: The most common is the DB25 and DE9, a typical application of PC is VGA (DA15 female head), parallel port (DB25 female head), COM a serial port (DE9 male head), although these interfaces are being DVI, HDMI, RJ45 Ethernet front-end ports and USB. DE9 was misreading into DB9 in personal computers became popular, as time passes DB9 became DE9 alias, for other pin number of D - sub, too, now use the DB to call relatively more. The d-sub simply describes the connection structure itself, which does not define the entire interface or all the pins D - for VGA Sub: The information processing by the graphics card are ultimately to output to the display, the output of the graphics interface is a bridge between the computer and monitor, it is responsible for to display the corresponding image signal output. The CRT display is designed for manufacturing reasons only to receive analog input, which requires the graphics card to enter the analog signal. The VGA interface is the interface for the output analog signals on the Graphics card, and the VGA (Video Graphics Array) interface is implemented with a 15-pin d-sub interface (DB15). Although liquid crystal displays can receive digital signals directly, many low-end products use VGA interfaces in order to match the VGA interface CARDS. The VGA interface is a type D interface with 15 stitches in three rows of five. The VGA interface is
