The A&D Weighing AD-8561-MI04 Multi-interface module is a versatile connectivity solution designed to streamline data transmission between various devices in the weighing process. With its D-sub 9 pin interface, it facilitates seamless bidirectional communication between a counting scale and external devices such as printers. Additionally, the module enables the transmission of comparator output signals, allowing for efficient coordination with devices like comparator lamps. Furthermore, users can input text data directly into the counting scale via USB Type-A interface, accommodating barcode readers or keyboards. These functionalities are enhanced when the AD-8561-MI04 is integrated with the GC-Series, offering a comprehensive solution for data management and control in weighing applications.
