10. ARDUINO CONFIGURATION Arduino Configuration: Ethernet Shield + Module PoE RS232 Shield Use Software Serial library in order to make two serial communications between RS232 – Arduino – Ethernet. Project Description Server Preparation Arduino Programming Future Development Conclusion Introduction

11. SERIAL COMMUNICATION RS232 Protocol : Baudrate: 1200; Parity: no; Databits: 8; Stopbits: 1 To retrieve the data the PC must send F Response of the SCD: In this sequence the data will be returned as ASCII signs. R: current voltage; current power; current temperature; minimum voltage; maximum voltage; minimum power; maximum power; CRLF R:12,85;13,0; 9;11,60;21,94; 8,9;15,8; Project Description Server Preparation Arduino Programming Future Development Conclusion Introduction
