It includes LED indicators to display data activity and status, giving quick, at-a-glance diagnostics of the RS-232 side and the RS-422 link. The device is described by the manufacturer as RS-232\/422 Converter with LEDs and is classified as light industrial ITE equipment, reflecting its intended use in modest industrial settings. A Declaration of Conformity references European standards such as EN 50082-1 (IEC 801-2, IEC 801-3, IEC 801-4), EN 50081-1 (EN 55022, IEC 1000-4-2), EN 61000-4 (2, 3, 4, 5, 6, 8, 11), ENV 50204, and EN 55024, signaling EMI and safety compliance. Guidance within the accompanying documentation recommends proper grounding: connect protective ground and signal ground at each end of the system and, for shielded twisted-pair installations, bond the shield to protective ground, with a 100-ohm, 1\/2-watt resistor recommended at one end to aid impedance matching. These details together describe a purpose-built, non-isolated serial bridge suitable for converting RS-232 signals to RS-422 form and integrating legacy equipment with modern differential networks, all from the B\u0026amp;B Electronics lineage (often associated with the B\u0026amp;B SmartWorx product family). \u003c\/p\u003e\u003c\/div\u003e","brand":"B\u0026B","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51660451578158,"sku":null,"price":283.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_2beb33a6-5a41-490e-b46e-07f507860a2f.jpg?v=1769537758","url":"https:\/\/plgautomation.com\/products\/b-b-electronics-422lcon-rs-422-line-converter","provider":"PLG Automation ","version":"1.0","type":"link"}
