This is a 3-metre USB RS232 to DB25 D-SUB 25PIN MALE ADAPTER designed for serial communication. Key benefits - Functionality: Acts as a null modem serial communication cable to enable seamless data transfer between RS232 devices. - Compatibility: Connects devices that require an RS232 interface to systems or connectors with DB25 (D-SUB 25PIN) male ports. - Size and flexibility: 3 metre length provides flexible placement and easier cable routing in varied workspaces. - Connection reliability: Male DB25 connector delivers a stable and reliable interface for serial tasks. Use scenarios - Connect a legacy RS232 device with a DB25 port to a USB-based RS232 host or adapter to transfer data and control signals. - Establish a null-modem link between two RS232 devices in a lab, workshop, or maintenance setting for testing and data exchange. - Use in field or production environments where a 3 metre reach is required to connect equipment located away from the host system.
