Top Three Benefits Of Using Rs232 To Rs485 Converters-ravbin

UnCategorized This article describes the top three benefits of using RS232 to RS485 converters – a niche market servicing these legacy serial .munications protocols. RS485 is an electrical interface standard still widely used by industrial automation devices such as sensors, motor managers, temperature controllers and control valves that .municate real-time, deterministic data across bus-based networks. Although newer devices that make use of Ethernet-based network protocols are gradually replacing it, there remains a very large installed base worldwide where the simplicity and reliability of serial RS485 .munications continues to work well. Benefit #1: Plug and Play Connectivity: There’s an old joke sometimes shared by veteran .munications engineers that goes: "the wonderful thing about standards is that there are so many to pick from". A great example is the success of RS 232 in the personal .puter and .munications world and of RS485 (and also RS422) in industrial automation environments. These standards are not directly .patible but it became necessary for control and instrumentation purposes to have .puters (via their RS232 ports) .municate with devices supporting RS485. In order to meet these requirements best-in-class RS232 to RS485 converters usually have at least the following two features: a) Port-powered from the RS-232 side. For many applications this is fine but for longer line lengths, or for RS485 networks with hundreds of nodes, the converter should also support an external power adapter. b) No software drivers required. The converter should automatically turn on the RS485 transmitter after detecting data on the RS232 interface and return to receive mode once the character has been sent. Enabling the half duplex RS485 interface to .municate with the standard RS 232 port, without the .plexity of software drivers, makes the converter much simpler to use. Benefit #2: Supports A Range of Transmission Rates: From 300 bps to around 115,200 kbps should be sufficient for many legacy applications. (Note that RS485 supports data rates of up to 10 Mbps over about 50 ft. and up to 100 kbps at the maximum distance of around 4000 ft.) Benefit #3: Function in Electrically Hazardous Environments: In some industrial environments static electricity is a real problem and makes it necessary to protect against voltage spikes and ground loops. Externally powered RS232 to RS485 converters with optical isolation are designed to function here. Note that maximum transfer rate and distance may vary considerably between manufacturers. Conclusion. The RS232 standard has been around since the early 1960s and the latest version of the RS485 standard since the mid-1980s. As both will likely be widely used for many more years to .e, the need for reliable, safe and easy to operate RS232 / RS485 converters is an important one. USconverters will continue to provide customers with quality and affordable converters to meet these needs. About the Author: By: Shirley B.
