It is a plug-and-play 4K HDMI auto switcher for meeting rooms and classrooms where two sources share one display, and it can be powered over PoE from the LAN port for a clean installation.\u003c\/p\u003e\u003ch2\u003eHow does the Kramer SWT3-21-H work?\u003c\/h2\u003e\u003cp\u003eWhen a presenter connects a laptop, the SWT3-21-H detects the active HDMI signal and routes it to the display according to the configured rule, either input priority or last connected. HDMI switching is HDCP 2.2 compliant at up to 18Gbps, and Kramer I-EDIDPro intelligent EDID processing handles, locks and passes EDID so sources and displays work together without manual setup. Up to 32 channels of uncompressed digital audio pass through, and the audio on the HDMI output is also de-embedded to a balanced stereo analog output for a room amplifier or DSP.\u003c\/p\u003e\u003cp\u003eThe switcher can turn a CEC-enabled or serially controlled display on and off when a source is plugged in or removed, with a user-defined shutdown delay. Its built-in control gateway lets an IP controller send RS-232 or I\/O commands to connected devices, and six GPIO pins can trigger configured functions from remote contact-closure buttons. Operation is available through a browser web page, local panel buttons and IP control, with 802.1x authentication for secured IT network connection. The compact DemiTOOLS fan-less enclosure can be powered by PoE or the included 5V DC supply.\u003c\/p\u003e\u003cp\u003eFor rooms with more sources, the \u003ca href=\"https:\/\/creationnetworks.net\/products\/kramer-vs-411x-4x1-4k-hdr-hdmi-auto-switcher\"\u003eKramer VS-411X 4x1 HDMI auto switcher\u003c\/a\u003e is a related option, and the \u003ca href=\"https:\/\/creationnetworks.net\/products\/kramer-ext3-21-xr-tr-2x1-4k60-hdmi-usb-switcher-extender-over-hdbaset-3-0\"\u003eKramer EXT3-21-XR-TR switcher extender\u003c\/a\u003e adds HDBaseT 3.0 extension and USB.\u003c\/p\u003e\u003ch2\u003eWhat are the key features of the Kramer SWT3-21-H?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuto switching\u003c\/strong\u003e — Selects the source automatically by priority or last-connected input.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4K60 4:4:4 HDMI\u003c\/strong\u003e — 18Gbps HDMI switching with HDCP 2.2 compliance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eI-EDIDPro\u003c\/strong\u003e — Intelligent EDID handling, locking and pass-through for plug-and-play operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAudio de-embedding\u003c\/strong\u003e — HDMI audio is also sent to a balanced stereo analog output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay on\/off control\u003c\/strong\u003e — Powers CEC or serially controlled displays with the source, with a shutdown delay.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in control gateway\u003c\/strong\u003e — IP-driven control of connected devices via RS-232 or I\/O.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecured network operation\u003c\/strong\u003e — 802.1x authentication for IT LAN connection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoE powering\u003c\/strong\u003e — Powered from the LAN port, in a compact fan-less DemiTOOLS enclosure.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere is the Kramer SWT3-21-H typically used?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHuddle room\u003c\/li\u003e\n\u003cli\u003eConference room\u003c\/li\u003e\n\u003cli\u003eTraining room\u003c\/li\u003e\n\u003cli\u003eCommercial meeting space\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable style=\"width:100%;max-width:100%;table-layout:fixed;border-collapse:collapse\"\u003e\n\u003ccolgroup\u003e\n\u003ccol style=\"width:38%\"\u003e\n\u003ccol style=\"width:62%\"\u003e\n\u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInputs\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2 HDMI (female HDMI connectors)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOutputs\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1 HDMI;
