Each of the two ports supports RS-232, RS-422, or RS-485 operation (2-wire or 4-wire), enabling flexible communication with a wide range of devices such as PLCs, sensors, and industrial controllers. The device provides a standard RJ-45 Ethernet port for network access and is powered via a DC input for reliable operation in demanding environments. Its compact DIN-rail form factor is intended for panel installations, saving space in control cabinets. As an older model, BB-VESR902D is listed as obsolete by distributors and is no longer manufactured by Advantech, with remaining stock typically found through secondary channels. This combination of dual serial interfaces, multi-mode serial support, and an Ethernet backbone makes it suitable for tasks like remote device management, fieldbus gateway applications, and bridging legacy equipment to modern networks.\u003c\/p\u003e\u003c\/div\u003e","brand":"Advantech","offers":[{"title":"New","offer_id":51657038070062,"sku":null,"price":704.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_45563616-efee-4fc5-982d-d0ac0dc2ef41.jpg?v=1769465433","url":"https:\/\/plgautomation.com\/products\/advantech-bb-vesr902d-2-port-ethernet-serial-server","provider":"PLG Automation ","version":"1.0","type":"link"}
