1. Application:
Network cable: Mainly used for data transmission in network communications such as computers, routers, switches, and telephones;
485 line: Standard communication interface for industrial field equipment, used to transmit control signals.
2. Differences
(1) Different functions. RS485 is used to transmit control signals, while Ethernet obtains network data through the Internet;
(2) Different wire materials used. RS485 can be transmitted with a 2-core wire, while Ethernet must use an 8-core shielded wire, and at least 4 cores must be connected, and they cannot be connected incorrectly;
(3) Different interfaces. Network cables generally use RJ45 interfaces, while RS485 uses RS485 interfaces.
