Two USB type-A HID ports extend keyboard, mouse, and other HID-class peripherals back to the source, with device class filtering fixed at the factory so the port cannot be reconfigured for mass storage or other USB classes -- a security feature the SR 301's general-purpose USB 2.0 port does not have. Audio de-embeds to a digital HDMI-embedded output or a 3.5 mm analog stereo connector, with bidirectional RS-232 and IR pass-through control on the same fiber run. This lossless variant uses 1 SFP (mathematically lossless 4K\/60 over one fiber), giving a maximum channel data rate of 10.0 Gbps (1 fiber). Power is internal, 100-240 VAC.\u003c\/p\u003e\n\u003ch3\u003eKey Capabilities\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBuilt-in scaler outputs fixed resolutions up to 4096x2160 at 60 Hz, or bypass mode\u003c\/li\u003e\n\u003cli\u003e2-port USB HID hub with factory-locked device class filtering\u003c\/li\u003e\n\u003cli\u003e20 km (12.4 miles) on singlemode fiber\u003c\/li\u003e\n\u003cli\u003eBidirectional RS-232 and IR pass-through control\u003c\/li\u003e\n\u003cli\u003eHalf-rack metal enclosure with optional rack shelf or under-desk mount\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhere It Is Used\u003c\/h3\u003e\n\u003cp\u003eSecure workstation KVM extension in command centers and classified environments that need HDMI scaling, locked-down HID-only USB, and RS-232\/IR device control over fiber specify the SR 311 alongside a matching FOX3 T 311 transmitter or FOX3 Matrix frame.\u003c\/p\u003e\n\u003ch3\u003eSpecifications at a Glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOptical link: 1 SFP (mathematically lossless 4K\/60 over one fiber), 1 LC connector, 20 km (12.4 miles)\u003c\/li\u003e\n\u003cli\u003eVideo output: 1 HDMI, scaled or bypass, up to 4096x2160 at 60 Hz 4:4:4\u003c\/li\u003e\n\u003cli\u003eUSB: 2-port USB HID hub, device class filtered\u003c\/li\u003e\n\u003cli\u003eEnclosure: 1.7\" H x 8.75\" W x 8.5\" D (half rack wide)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"alt-refs\"\u003eAlso referenced as Extron FOX3SR311SM, FOX3-SR-311-SM, part number 60173222.\u003c\/p\u003e","brand":"Extron","offers":[{"title":"Default Title","offer_id":52302271381724,"sku":"EXTRON-FOX3SR311SM-60173222","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0754\/5582\/4092\/files\/extron-fox3-sr-311-sm-60-1732-22.jpg?v=1787221574","url":"https:\/\/www.ampronix.com\/products\/extron-fox3-sr-311-sm-60-1732-22","provider":"Ampronix","version":"1.0","type":"link"}
