D-sub 9 ConnectorThe DE-9 D-sub 9-pin connector is often mistakenly referred to as the "DB-9" connector. The "E" refers to the shell size. A "DB-25" connector has a "B" size shell, but the common nine-pin connector is smaller and has an "E" size shell. This connector (regardless what you call it) is used for a variety of purposes. Two common applications are RS-232/EIA-232 (serial) connections (including UPS cables), and a variety of video interfaces on the IBM PC. Here's a good set of figures for D-sub 9 male and female connectors, as viewed from the pin side (not the solder side).
