Abstract

This invention relates to a serial connection device capable of being used as signal transmission and power transmission means at the same time, which includes a serial port having a plurality of pins and is electrically connected to an external serial equipment through a cable, a signal/electric power swapping device which is electrically connected with one pin of the serial port and as a switch-swapping selector; a serial signal end, which is electrically connected to one of the switch-swapping selection end of the signal/power swapping device; an electric power source end, which is electrically connected to another switch-swapping selection end of the signal/electric power swapping device. This invention provides a connector design allowing flexible choice of electric power output specifications under the definition of EIA-RS-232, EIA-RS422 and EIA-RA-485 standards, thus increasing the usage convenience greatly.
