DB9 Serial Connector Diagram - Pinout and Physical Layout #1946708 (License: Personal Use)

This black-and-white line illustration depicts a DB9 male D-subminiature connector, featuring nine circular pin holes arranged in two rows (5 on top, 4 on bottom) within a trapezoidal metal shell. The two mounting screw holes on either side are shown as circles, indicating where the connector attaches to a panel or cable housing. The clean, minimalist style emphasizes form and function over realism, making it ideal for technical documentation and educational materials.

This image is typically used in electronics tutorials, hardware manuals, datasheets, and troubleshooting guides to illustrate the physical layout of a DB9 serial port-especially for RS-232 interfacing. It serves users seeking to identify pinouts, build cables, or understand legacy connectivity standards.
