Abstract
A functional extended system of network communication device and its method are disclosed according to the present invention. The functional extended system of network communication device and its method are applicable to a network communication function extended equipment that is connecting to a network communication device that has universal communication transmit port, mainly it connects to the universal communication transmit port of the network communication device via an extended communication transmit port, and it also has its data processing unit and the network communication device produce a handshake based on a preset communication protocol, and then it has the data processing unit execute data process that includes at least encoding/decoding data transmitted from/to the network communication device based on the preset communication protocol, thus the data processing unit is able to drive corresponding functional extended module to execute extending function, and/or it can further connect with other functional extended system of network communication device, therefore, the network communication device is capable of extending continually.
