An Implementation of Protocol Converter Between Ethernet & RS-232

Abstract

The purpose of this study is to develop conversion software to enable two systems with different protocols to communicate and convert packet type from Ethernet to R-232 and vise verse to enable data and command transmission. Protocol conversion has become a necessity for the internetworking in a heterogeneous network environment. Incompatibility between Ethernet and RS232 is the reason of implement this study which means differ of packet for example In serial communication (R-S232) needs additional fields for ‘ start of packet’ and ‘end of packet’ which not needed for Ethernet packet. Protocol converter has been proposed in this study to solve incompatibility between Ethernet and RS-232 .the result of running programs in three PCs is investigated the matching of data in PC1 and PC3 that mean PC2 successful converted Ethernet data to RS-232 data.
