RS-4350 is a national standard in the United States for serial communication interfaces. It defines the electrical characteristics, mechanical connectors, and functional protocols for transmitting serial data between devices at distances of up to 1,200 meters (3,937 feet) using RG-45 coaxial cable. This standard covers both simplex and duplex data transmission and supports various data rates from 5pt to 64Kbps. The RS-4350 standard is commonly used in industrial automation, telecommunications, and other applications that require reliable, long-distance serial communication over coaxial cable.
