Powered from the USB bus, it ships with a 3‑ft USB cable and requires no external power supply. It supports RS-485 in both 2-wire and 4-wire configurations (RS-422\/485), with A\/B differential signaling and ground, and baud rates up to 921 kbps. It exposes a single serial channel to the host and, on Windows, the device appears as an additional COM port in Device Manager. The IC833A also supports Send Data Control (SDC) and lists TDA, TDB, RDA, RDB, and GND as supported signals. Automatic configuration is described for legacy Windows systems (Windows 98, ME, 2000, XP, and Vista), simplifying setup on older machines. This converter is suitable for connecting non‑USB RS-485 equipment to modern computers for data acquisition, telemetry, or testing without modifying the existing network.\u003c\/p\u003e\u003c\/div\u003e","brand":"Black","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51677088809262,"sku":null,"price":70.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_457902f7-2f96-4885-9c46-83a59d221a9c.jpg?v=1769557607","url":"https:\/\/plgautomation.com\/products\/black-box-ic833a-mini-converter-usb-to-serial-rs-485-4-wire","provider":"PLG Automation ","version":"1.0","type":"link"}
