peel out RS485 communication cable, then connect back of the DVR panel. in RS 485 control system then ... go to protocol setting in the DVR on that assign camera ID.. then save.. finish.
The United States of America invented the electronic standard RS-485.
RS-485 is a two wire serial protocol.
RS232 means "Recommended standard no. 232", EIA standard for serial communication Thirumalesha.....
Yes. Most use wall-wart transformers.
The "RS" in RS-232 stands for "Recommended Standard." RS-232 is a standard for serial communication that was introduced by the Electronic Industries Association (EIA) in the 1960s. It defines the electrical characteristics and timing of signals, as well as the physical size and pinout of connectors used for serial data exchange.
Recommended Standard 232
RS-422 is a standard for serial data communication that allows for long-distance transmission of data at high speeds. It uses differential signaling, which enhances noise immunity and allows for communication over distances up to 4,000 feet (1,200 meters) at data rates of up to 10 Mbps. RS-422 can support multiple receivers on the same line but is primarily designed for point-to-point communication. This standard is commonly used in industrial automation, telecommunications, and computer networking applications.
Its not, it just happens to be convenient. Other standards for UART communication include RS-422, RS-423, RS-481, and various others.
RS-232 is used over serial ports, which are typically found on computers and various electronic devices for communication. It transmits data one bit at a time, using a standard defined by the EIA (Electronic Industries Alliance). Commonly, RS-232 ports are DB9 or DB25 connectors, though modern devices may use USB-to-serial adapters to facilitate RS-232 communication.
