On the host side it uses a USB 2.0 interface, while the RS-485 side provides a two-wire differential port terminated by a plug‑in terminal block for A\/B wiring. The 2W designation identifies two-wire, RS-485 half‑duplex signaling suitable for multi‑point networks common in industrial environments. This model is part of Advantech’s BB-485USBTB family, which also includes the BB-485USBTB-4W and locked-serial-number LS variants, offering options for different wiring needs and deployment constraints. Typical applications span industrial automation, data acquisition, building management, and equipment interfacing where a USB host must control or collect data from RS-485 devices such as sensors, actuators, or motor controllers. The device is designed as a compact, plug‑in solution that integrates with standard USB hosts and simplifies adding RS-485 connectivity to existing control or monitoring systems without requiring a separate RS-485 controller. \u003c\/p\u003e\u003c\/div\u003e","brand":"BB","offers":[{"title":"New","offer_id":51660474122542,"sku":null,"price":145.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_93550d5c-4485-45dc-9541-f58217f307b3.jpg?v=1769538015","url":"https:\/\/plgautomation.com\/products\/advantech-bb-485usbtb-2w-usb-to-rs-485-2-wire-signal-converter","provider":"PLG Automation ","version":"1.0","type":"link"}
