Description:

This pair is a typical standard 9-pin RS232 connector set by solder type. They are also referred to as DB9 connectors. A computer serial COM port (DTE) is usually a male port, and any peripheral device to be connected to this port usually has a female connector (DCE). Hobbyists normally use them to make data downloading devices.
