To maintain system uptime, these dual coaxial segments are physically isolated and routed along separate paths throughout the facility.Connection to the active token-passing network is executed through standardized BNC tee connectors (part number 51190728-105). These tees allow a technician to pull the board or drop a single node entirely offline without breaking the physical continuity of the coaxial segment or interfering with surrounding node traffic. Additionally, this module hosts the physical hardware switches where the unique LCN device network address must be assigned prior to system node initialization.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":47605282308286,"sku":"51107403-100","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-06-05_17-41-02_70eed645-4413-421a-8671-f711682e68a7.png?v=1780653473","url":"https:\/\/www.autooiltech.com\/products\/honeywell-51107403-100-local-control-network-adapter-board","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
