Description
The Kramer SWT3-41-U is a 4×1 USB 3.2 switcher that centralizes multiple USB hosts to share room peripherals. It supports two USB-C hosts and two USB-B hosts and provides automatic host switching based on active USB signal detection. The unit is designed to simplify AV collaboration by allowing a single set of cameras, microphones and HID devices to be shared between connected hosts.
Key capabilities include USB 3.2 data switching at up to 10 Gbps, integrated USB hub functionality, and USB-C host power delivery up to 60W when powered by the 20V supply. The switcher supports PoE powering via the LAN port and includes IP-based control, local panel buttons and contact-closure triggers. Auto switch preferences can be configured so the device connects hosts according to last-connected or active-signal rules.
Technical performance is driven by USB 3.2 Gen2 support and a 10Gbps data rate that accommodates high-resolution cameras and multichannel audio devices. The unit integrates an internal USB hub and supports USB device charging up to a total of 2A. Power options include the supplied 20V DC PSU or an optional 12V DC PSU, with PoE available as an alternate power source.
Connectivity includes one RJ-45 LAN port for network management and PoE, one RS-232 3-pin terminal for control integration, and two GPIO contact inputs. Device-level ports include three USB-A device ports and one USB-C device port for room peripherals. The switcher also supports IT-grade 802.1x authentication for secured LAN operation and can be managed via an embedded web page or remote IP control.
Typical applications include enterprise and education meeting rooms, AV rooms upgraded to support multiple laptop hosts, and any space that needs shared camera and microphone resources across several users. The SWT3-41-U is useful where participants bring their own devices and need single-cable USB-C connectivity with data, Ethernet and optional PD charging. It simplifies workflows by enabling quick switching between presenters and maintaining consistent peripheral access.
Installation is straightforward with PoE powering options and a MegaTOOLS fanless enclosure that supports desktop, under-table, dropped-ceiling or side-by-side 1U rack mounting with an adapter. Local LEDs assist with maintenance and troubleshooting while remote firmware updates are available via the embedded web interface. The fanless design and compact footprint reduce noise and simplify integration into meeting spaces.
