Detail RS-485 is an electrical-only standard. Unlike full interface standards, which define functional, mechanical, and electrical specifications, RS-485 only defines the electrical characteristics of drivers and receivers that could be used to implement a balanced multidrop transmission line. This standard, however, is intended to be referenced by higher level standards, such as DL/T645, for example, which defines the communication protocol. for electronic energy meters in China, specifying RS-485 as the physical layer standard. Features 1.Heat resistant, flame retardant 2.excellent insulation performance, stable chemical performance 3.excellent transmission performance due to the use of high quality polyethylene for braided cable shielding 4.Effective resistance to electromagnetic interference due to use Made of a new type of aluminum foil, double-layer braided copper mesh shielding. Applications RS-485 signals are used in a wide range of computer and automation systems. In a computer system, SCSI-2 and SCSI-3 can use this specification to implement the physical layer for data transmission between a controller and a disk drive. RS-485 is used for low-speed data communications in commercial aircraft cabin vehicle buses. It requires minimal wiring and can share wiring between multiple seats, reducing weight.
