Backplane bus interface circuitry translates parallel Multibus read\/write cycles into deterministic network packets, allowing integration with process control networks including FOUNDATION Fieldbus and Profibus PA link couplers. Galvanic isolation on the network port prevents ground loop potential differences across distributed control system nodes.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the PBA455971-003 LAN controller card be hot-swapped into an active Multibus backplane?\u003c\/p\u003e\n\u003cp\u003eA: No. Multibus (IEEE-796) architecture does not support live insertion; power to the rack enclosure must be shut off prior to installing or removing the card to prevent backplane damage.\u003c\/p\u003e\n\u003cp\u003eQ: How is the physical network media type selected on the PBA455971-003 board?\u003c\/p\u003e\n\u003cp\u003eA: Hardware jumper headers located near the board edge select signal routing between the RJ45 twisted-pair interface and the BNC co-axial connector.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eCard Insertion\u003c\/strong\u003e: Align the PCB card edges with the backplane card guides and push firmly until the IEEE-796 edge connectors seat completely in the chassis receptacle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMedia Selection\u003c\/strong\u003e: Verify that on-board jumper settings match the target physical medium (RJ45 10Base-T or BNC 10Base-2 coaxial) before applying rack power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Shielding\u003c\/strong\u003e: Ensure coaxial cable runs use 50-ohm RG-58 cable with properly grounded BNC end-terminators to mitigate high-frequency EMI.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Spacing\u003c\/strong\u003e: Maintain at least one open card slot or chassis fan airflow pathway adjacent to the controller card to ensure ambient operating temperatures stay below +60 deg C.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":67654730187061,"sku":"PBA455971-003","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/PBA455971-003.png?v=1791440209","url":"https:\/\/www.5gplc.com\/products\/honeywell-intel-multibus-pc-at-lan-controller-pba455971-003","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
