The USB to RS485 Converter / USB to RS422 Converter.

The USB to RS485 converter and USB RS422 adapter, also called USB to RS485 / USB RS422 converters, are small electronic devices used for converting a USB signal into either RS485 or RS422. Some of these converter / adapter units can convert only USB to RS485 or USB to RS422 but others can convert both RS485 and RS422 at the same time. All convert bi-directionally meaning they convert the data signal in both directions.

These USB to RS485 converter and USB to RS422 adapters are most often used for connecting a RS485 or RS422 device to a personal computer. Since most computers do not have a RS485 or RS422 port, but they do have a USB port, you can use a USB to RS485 converter or USB to RS422 adapter to interface between your computer and your device.

The USB to RS485 converter and USB RS422 adapter is made in a variety of models and designs. The standard USB RS485 converter / USB to RS422 adapter is a non-isolated adapter which is used for many business, office and personal devices. The isolated USB to RS485 converter / USB to RS422 adapter is used in many industrial and business environments since these are resistant to moderate voltage spikes and noise levels.

Choosing the correct USB RS485 converter or USB RS422 adapter is often a fairly easy task since most converters / adapters work within a range of multiple settings. The most important thing to keep in mind when choosing a USB RS485 converter or USB RS422 adapter is if you need a standard or industrial strength USB to RS485 converter or USB to RS422 adapter and whether it needs to be isolated or non-isolated.

USB to RS485 is known for its multi-drop characteristics, meaning you can use USB RS485 for connecting multiple RS485 devices in a two-wire network. USB to RS422 is often used for extending a RS232 wire by using a USB to RS422 adapter at each end of a RS232 wire.
