Bipolar / RS 232 (RS-232C) interconversion device and method

摘要

The present invention relates to an apparatus for inputting and outputting information between a system and a keyset matched with a bipolar signal as an RS-232C signal, and more particularly to a bipolar / RS-232C signal interconversion apparatus and method.;An object of the present invention is to reduce the number of repeatedly inputting numbers in a telegraph automatic apparatus terminal and a key set by a navigator during a call incoming or outgoing in the entire electronic exchanger system to automatically process the same.;This device is implemented to enable real-time service by converting the signal between these bipolar / RS-232C.
