Kramer SWT3-41-U – 4x1 USB 3.2 Host Switcher
What is the Kramer SWT3-41-U USB switcher?
The Kramer SWT3-41-U is a 4x1 USB 3.2 switcher with two USB-C and two USB-B host ports, built to share a meeting room's USB peripherals between up to four computers. It auto-switches to the active USB host, so the room camera, microphone and other connected peripherals move to whichever laptop or room PC is in use. It is a simple way to upgrade an AV meeting room into a hybrid meeting room.
How does the Kramer SWT3-41-U work?
Host computers connect to the two USB-C ports, which also support USB Power Delivery 3.0, or to the two USB-B ports. The SWT3-41-U detects active USB signals and automatically connects the integrated USB hub to that host. Four device ports, three USB-A and one USB-C, accept the room's conferencing peripherals such as cameras, microphones and speakerphones, with USB 3.2 data rates up to 10Gbps.
For control, the switcher has an Ethernet port for LAN connection, an RS-232 port and two GPIO pins, so a control system or wall button can force a specific host. A built-in intelligent control gateway, secured operation and cost-effective management tools support enterprise deployment. Power comes from the included 20V DC, 6A adapter.
To extend USB to a remote location, see the Kramer KDS-USB2 USB 2.0 extension kit; for a combined video and USB switcher, see the Kramer EXT3-21-XR-TR HDMI/USB switcher extender.
