Abstract：At present many embedded equipments need to connect Internet in the field of industrial control , intelligent instrument and information appliance, etc. In allusion to the actuality, we put forward a solution based on a single chip IP2022.It realizes the connection between embedded equipment with RS485 serial interface and Ethernet. The paper mostly introduces the IP2022 chip, the hardware structure, the system’s interface circuit and
the software design. The advantages of the project are small bulk, low power waste, short development time and high practicality value.
