RS-485 and RS-422 bus standards are used in industrial and instrumentation applications that require transmission of data between multiple systems often over long distances. The RS-485 interface is the telecommunication industry’s most widely used transmission line standard and is normally used with a higher-level protocol, such as Profibus, Interbus, Modbus, or BACnet. This allows for robust data transmission over relatively long distances. RS-422 is specified as a simplex multidrop standard, which means that only one driver and up to ten receivers can be connected to the same bus. If more than one driver needs to be connected on the same bus, then RS-485 is recommended. RS-485 is specified as a multipoint standard, which means up to 32 transceivers can be connected on the same bus. Analog Devices’ ADM2482 and ADM2487 are isolated RS-485 and RS-422 data transceivers widely used in high-speed communication on multipoint transmission lines. Murata’s 782482 converter transformers are specifically designed and approved for use with these transceiver chipsets.
