RS232–RS485 CONVERTER
RS232 to RS485 serial communication converter for connecting devices with different interfaces.
Description
The RS232 to RS485 converter is a device designed to enable communication between equipment using different serial interface standards. While RS232 is widely used for short-distance communication, RS485 provides a more robust and efficient solution for long-distance connections and industrial environments. This converter connects devices with RS232 interfaces to RS485 networks, ensuring stable, high-performance communication in applications requiring greater resistance to electromagnetic interference and multipoint transmission.
The converters are built to strict quality standards using state-of-the-art electronic components (SMD). Their hardware is designed to withstand harsh operating conditions and can be installed directly in power substation panels. They meet the requirements for performance, withstand capability and reliability specified by IEC, DIN, IEEE and ABNT standards.
