Durable and reliable Built with electronic components and a precise manufacturing process to ensure long term durability. Extensive compatibility Compatible with RS232C and RS485 standards, enabling use with a wide range of legacy serial devices and RS485 networks. Easy conversion and long reach Converts single ended RS232 signals to balanced RS485 differential signals. Extends communication distance up to 1.2 kilometre, supporting longer cable runs without additional power. Passive and simple to use The converter is passive and does not require an external power supply, simplifying installation and reducing clutter. Key benefits at a glance Improves serial interoperability between RS232 and RS485 systems Enables longer distance communication with robust differential signaling No external power needed, reducing setup complexity and maintenance Use scenarios Industrial automation: connect a PC or controller to RS485 field devices such as sensors, actuators, or programmable logic controllers across the factory floor. Building automation: integrate legacy RS232 equipment with RS485 sensors and control networks for centralized monitoring and control. Laboratory and data acquisition: collect data from RS232 instruments over an RS485 network to a central data logger or computer for analysis.
