When installed in human-machine interface (HMI) nodes monitoring broad DCS assets—including FOUNDATION Fieldbus and Profibus PA segments—the assembly isolates internal console control logic from physical static discharge and ground potential variations, preventing cursor jitter during active plant operations.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 51196694-928 upgrade board be installed while the operator console is powered on?\u003c\/p\u003e\n\u003cp\u003eA: Hot-plugging the PS\/2 interface board is not supported; console power must be isolated prior to removing the trackball housing and connecting the board assembly.\u003c\/p\u003e\n\u003cp\u003eQ: Does the 51196694-928 require external software driver installation on the Honeywell operator station?\u003c\/p\u003e\n\u003cp\u003eA: The board provides direct hardware-level PS\/2 protocol translation, utilizing standard operating system peripheral drivers native to the console architecture.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003ePower down the operator station console and disconnect primary DC power feeds before opening the trackball assembly housing.\u003c\/li\u003e\n\u003cli\u003eObserve proper ESD protection procedures, including wearing a grounded wrist strap, when handling the bare printed circuit board.\u003c\/li\u003e\n\u003cli\u003eAlign the 51196694-928 board with internal mounting standoffs and secure it using non-conductive or specified retention hardware.\u003c\/li\u003e\n\u003cli\u003eVerify that the trackball mechanical sensor harness and PS\/2 output cable connectors are fully seated and latched before restoring console power.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":53567768199477,"sku":"51196694-928","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/51196694-928_Cocoai.png?v=1789365356","url":"https:\/\/www.5gplc.com\/products\/honeywell-51196694-928-ps-2-trackball-upgrade-board","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
