Abstrak

Serial communication is commonly used for PC interfaces. Nevertheless, the commonly used is RS-232, which can communicate one to one only. An achievement was made as a converter from RS 232 to RS 485 has successfully been constructed, whewreas the RS 485 system can communicate one to many using network multidrop system. The converter consists of three main components, i.e., IC Max 232, IC Max 491, and IC LM 555. This paper discusses the converter principal operation, the protocol signal planning , and the testiing of the signal coming in and out of the converter. As the final result, the converter is indeed a solution to the weak point of computer with terminal RS232 that can only setup one to one networking. The networking can now be extended to one to many network system by using RS485 cabl, but not necessarily replacing the terminal RS232 with terminal RS485
