KRAMER SWT3-21-HU-TR 2x1 4K60 USB–C/HDMI Switcher Extender
SWT3−21−HU−TR is a high−performance auto−switcher with one USB−C and one HDMI/USB input, HDMI output and long−range HDBaseT 3.0. The HDBaseT 3.0 port is configurable as either transmit (output) or receive (input) link. The unit extends a 4K60Hz (4:4:4) HDMI, USB 2.0, RS−232, IR and I/O signal over a 40 meter twisted pair cable. The local and remote connected USB peripherals, such as a room camera and microphone, are switchable for use of the switcher active USB host, for convenient hybrid meeting operation with both room and online participants. The unit is ideally deployed either at the presentation source end or at the display end. Hybrid–meeting Collaborative Switching — Controllable coupled–signals switching of both AV and USB host inputs, for concurrent connection with AV output and USB devices, allows collaborative hybrid meeting where meeting participants are switched to share their content with both room and online meeting participants. BYOD Ease and Convenience — BYOD Ease and Convenience — Connect any DP–Alt–Mode–capable USB–C device as an AV source using a single USB–C cable. The connection also provides USB and Ethernet access, and (if PD–2.0–capable) up to 60 watts of charging power. High Performance Standard Extender — Professional HDBaseT 3.0 extender for providing long–reach signals over twisted–pair copper infrastructures. SWT3–21–HU–TR is a standard extender that can be connected to any market–available HDBaseT–compliant extension product. For optimum extension reach and performance, use recommended Kramer cables. HDMI Signal Switching — HDCP 2.3 compliant, supporting deep color, x.v.Color™, CEC, HDMI uncompressed audio channels, Dolby TrueHD, DTS–HD, 2K, 4K, and 3D as specified in HDMI 2.0b. Flexible USB Switching and Extension — An active USB 3.2 host is connected to the switcher extender on either the transmitter or receiver sides. USB 2.0 signals are extended between the switcher extender transmitter and receiver sides, enabling connection and switching of the active USB host to both local USB 3.1 and remote USB 2.0 devices, such as camera and audio devices, or HID (Human Interface Devices) mouse or keyboard devices. HDMI Mirroring — On switcher transmitter side, active USB–C or HDMI input signal is transmitted on HDBT output, and in parallel mirrored to HDMI output port for connecting a local monitor or adding an additional unit in a daisy chain. I–EDIDPro™ Kramer Intelligent EDID Processing™ — Intelligent EDID handling, processing and pass–through algorithm that ensures Plug and Play operation. Multi–channel Audio Transmission — Up to 32 channels of digital stereo uncompressed signals for supporting studio–grade surround sound. Field–configurable HDBT direction — Instantly set the unit's role during power up. The unit is set to either a receiver (with 3 inputs — HDBT, USB–C and HDMI) or a transmitter (with 2 inputs — USB–C and HDMI and one HDBT output). Audio De–embedding — The digital audio signal passing to the output, is de–embedded, converted to an analog signal and sent to the stereo balanced analog audio output. This enables playing the audio on a locally connected professional audio system (such as DSP) and speakers, in parallel to playing it on the speakers connected to the AV acceptor device (such as TVs with speakers). K–Pair Support: — Automatically switches upon connection or disconnection of a local or extended input. Auto Switcher Ease of Use — Automatically plays the signal of the plugged source on the connected display with either last–connected or priority–based pre–selection. Easy Online Meeting System Integrated Connectivity — Built–in flexible auto–disconnection operation of USB devices, such as room cameras and soundbars, enable detection of BYOD presenter disconnection by online meeting systems for their auto–activation, convenient integration, and ease of end–user operation according to space changing hybrid sessions needs. Display On/Off Operation — Meeting presentation is simplified by manually or automatically turning ON/OFF a CEC–enabled or serially–controlled display when the presentation source is plugged in / unplugged with user–defined shut–down delay. Simple Control — Remote IP–controller connection, browser operation webpage, local panel buttons, or remotely connected contact–closure buttons, for easy and fully–flexible user port selection, signal routing, and switcher control. Built–in Intelligent Control Gateway — Remote IP–driven intelligent control of connected AV, USB and sensor devices via CEC, RS–232, IR or I/O. Eliminating the need for an external control gateway, this feature reduces installation complexity and costs, to enable easy integration with control systems, such as Kramer Control. Ethernet Extension — Ethernet interface data flows in both directions, allowing extension of up to 1 Gbps Ethernet connectivity for LAN communication and device control. Bidirectional RS–232 Extension — Serial interface data flows in both directions, allowing data transmission and device control. Bidirectional Infrared Extension — IR interface data flows in both directions, allowing remote control of peripheral devices located at either end of the extended line. Secured Network Connection — Standard IT–grade 802.1x authentication for secured IT LAN connectivity. Comprehensive Management — Local panel indication LEDs to facilitate easy local maintenance and troubleshooting. Remote IP–driven firmware upgrade and management via user–friendly embedded web pages and an optional site–wide management system, ensure lasting and field–proven deployment. Easy and Elegant Installation — A sleek and small sized unit that has a configurable role. It can be field programmed as either a transmitter (at the desk side) or a receiver (at the display side) to save valuable installation time.
Applications Enterprise and education hybrid meeting rooms and classrooms. Workspaces with remote display system and multiple AV+USB sources
