摘要： An electronic device has a physical port, and a control circuit coupled to the physical port. The control circuit is arranged to electrically sense the physical port, and operate the physical port as one of an Ethernet port and an RS-232 port based on electrically sensing the physical port. In some arrangements, the physical port operates as an Ethernet port at one time and an RS-232 port at another time. In some arrangements, the electronic device senses for Ethernet signals and RS-232 signals concurrently. In other arrangements, the electronic device senses for Ethernet signals and RS-232 signals at different times in an alternating manner.

摘要： In accordance with the teachings of this disclosure, an Ethernet device is provided that draws current below a predetermined voltage, and as the voltage across the device exceeds the threshold, the device transforms into a high-impedance state, appearing as a high impedance device. Once in the high-impedance state, the discovery process proceeds normally as the current drawn through the high-impedance device is no more than normally occurs due to leakage or other typical conditions. Thus, the IEEE discovery now proceeds normally in the higher voltage ranges (6V to 9V) where the device of this disclosure is effectively out of the circuit, causing no interference.

摘要： Methods and apparatus are disclosed for balancing power across all conductors of an Ethernet connection. Balancing circuitry is disclosed to allow an Ethernet midspan device to receive power from an Ethernet Power Sourcing Equipment (PSE) on the signal pairs of an Ethernet connection. The balancing circuitry is configured to sense the level of the received power, and generate a second power source substantially equal to the received power level. The received power is provided to an Ethernet Powered Device (PD) over the signal pairs of an Ethernet connection, and the generated power to the PD over the unused pairs of the Ethernet connection.

摘要： A method and apparatus for changing power class for a powered device are provided. During operation, a powered device, such as an IP telephone, receives power from a power source via a PoE device. In the event that the powered device detects connection to a second powered device, such as an IP telephone module, the powered device transmits a classification signal to the power source. Based upon the classification signal, the power source performs a powered device classification procedure to reclassify the powered device, such as according to an IEEE 802.3af standard, and provide an increase amount of power to the powered device. The powered device, in turn, provides a portion of the power to the modular device. The modular powered device, therefore, receives power directly from the first powered device and does not require additional equipment in order to operate.

摘要： Methods and apparatus for delivering power down all conductors of an Ethernet connection are disclosed. Embodiments include control circuitry coupled to both conductor of an Ethernet cable. The control circuitry is configured to sense the current flowing through power switches coupled inline with the respective conductors and control the switch in order to maintain the current flow through the power switch below a predetermined level. The circuitry prevents Ethernet ports from being shutting down due to conditions caused by imbalances in the effective resistance of Ethernet conductors and circuit paths.
