The keyboard function and the built-in USB speaker drop their connections on the host HIS PC, turning off status LEDs and ignoring all membrane key entries until the voltage returns to standard limits.\u003c\/p\u003e\n\u003cp\u003eQ: Can this 2.0 kg flat operation keyboard be plugged into an active HIS terminal while the system is running under load?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The unit complies with standard hot-plugging USB protocols. The host operating system detects the keyboard and speaker sub-devices automatically, runs the standard initialization steps, and restores operator input functions without causing process interruptions.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":47750575653054,"sku":"AIP821","price":3000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-05-15_11-03-08_abaf6d87-850a-4414-aa83-9370de9c62bd.png?v=1782374548","url":"https:\/\/www.autooiltech.com\/products\/yokogawa-aip821-industrial-flat-operation-keyboard","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
