RS232 to RS485 Converter Adapter compatibility and reliable conversion between RS232C and RS485 standards. This device enables RS232C equipment to communicate on an RS485 network with robust connectivity and clear data transmission. Extended distance capability. The converter supports communication distances up to 1.2 kilometres, allowing stable data transmission across large facilities and industrial environments. No power supply required. The adapter is passive and does not need an external power source, simplifying installation and improving compatibility with existing networking setups. Versatile usage across sectors. Suitable for industrial automation, canteen sales systems, employee attendance management, and highway toll stations. It is designed to adapt to a range of networking needs. Use scenarios Industrial automation: Connect an RS232C sensor or controller to an RS485 fieldbus or SCADA network over long distances without needing external power or additional converters. Canteen or retail point of : Link an RS232 POS terminal to an RS485 network to centralize sales data and update inventory or accounting systems. Facility access and toll systems: Integrate RS232 based terminals or controllers with RS485 networks at entry points or toll stations to enable centralized data collection and management.
