Abstract
A serial port connector with power output function includes a serial port having a plurality of pins. Under the existing EIA-RS-232, EIA-RS-422, and EIA-RS-485 standards for connectors, the definition of the pins of the serial port are altered, so that a pin that was originally defined as floating or for serial data communication signal is now changed to a power output specification. Thus, when the connector is connected via the same one cable to a serial port peripheral device, the connector can provide both functions of serial data communication signal transmission and power transmission to thereby largely increase the usability of the connector.
Claims18
A serial port connector with power output function, comprising:
- a serial port having a plurality of pins and being electrically connected via a cable to a peripheral serial port device to enable transmission of both serial data communication signal and power;
- a signal/power switch being electrically connected to one of the pins of the serial port;
- the signal/power switch being a jumper selector, and, via jumper selection with the jumper selector, the pin connected to the signal/power switch is switched to output signal or output power;
- a serial port signal terminal being electrically connected to one of two jumper selection ends on the signal/power switch for outputting serial data communication signal;
- and
- a power terminal being electrically connected to the other jumper selection end on the signal/power switch for outputting power.
