Serial Port And Ethernet Data Transmission

Data conversion module can be applied to the situation that need long range to deliver files in serial device, such as the numerical control machine tool transmit files with long range .First ,this text introduced a domestic and international research present condition, throngh compare and analyse, I select the RCM2200 mold piece of the RABBIT company to carry out data transmission between ethernet and serial, and then, I introduce the RCM2200 tiny controller core module and the software development environments-Dynamic C. In this foundation ,I choose and carry out transmission protocol of serial and ethernet, namely Xmodem and TFTP protocol. Finally,I Introduced the whole project that carry out document deliver, through experimen in computer and real use in digital-control machine control the tool machine through thet of the calculator actual application, all achieved the better result.
