Study of Serial Port Server/Switch Based on CS6209

A kind of solution that serial communication devices connect to the management network.This scheme adopts Myson Century CS6209 chip as the main MCU,incorporating C8051-compatible micro-controller core and integrating Ethernet interface(MAC and PHY),it is a kind of ultra low-cost serial server solution.In this paper,the composition of the serial server is described firstly.Then,a solution that serial communication devices connect to the management network is proposed.That solution adopts Myson Century CS6209 chip as the main MCU,incorporating C8051-compatible micro-controller core and integrating Ethernet interface(MAC and PHY),it is a kind of ultra low-cost serial server solution.After that,the structure of TCP/IP protocol stack,system software architecture and hardware design and verification of this program are all introduced.Finally,it sums up and makes an instruction of CS6209's practical and facility.
