With the shift to hybrid and remote work, the US3344i is a great fit for professional workspaces – enhancing your BYOM/BYOD meeting experience with ease. Meeting room setups are straightforward and effortless, thanks to its plug-and-play design that allows connections to up to 4 PCs/laptops and sharing of up to 4 USB 3.2 Gen 1 devices in no time. With blazing-fast data transmission, cross-platform compatibility (e.g. Windows, macOS, Linux), and flexible port-switching, the USB sharing switch further streamlines meeting workflows, enhances collaboration, and reduces the overhead of IT procurement and management for workplaces.
The US3344i eliminates the additional cost and hassle of implementing complicated, redundant systems and equipment for each computer. Its chassis and rack-mountable design make it highly suitable for industrial environments, simplifying and tidying the working area within the larger industrial setting.
Plug in – Collaborate – Share in Seconds
Join the meeting anytime to start the discussion, share data, or switch to collaborate – all in just seconds.

Seamless Integration into Control System
The US3344i can be seamlessly integrated into any reputable control system (including ATEN’s VK1100A, VK211), as part of the meeting room setup via its serial connectivity, subsequently utilizing the IP control function. The control system serves as a centralized platform to streamline AV/IT management and simplify maintenance.

Auto-switch for Efficient Control
The US3344i will shift the PC focus to the most recently connected host device automatically, with the corresponding port LED illuminated to indicate which active port has control over the resources.
Up to 5 Gbps Data Transfer Rate with USB 3.2 Gen 1
To maintain an efficient meeting flow, take advantage of the superior 5 Gbps data transfer speed of the built-in USB 3.2 Gen 1 ports, which are also backward compatible with USB 2.0/1.1 devices.

Maximize Project Versatility with Dual Power Support
The US3344i can be flexibly deployed with dual power options. The DC12V power adapter can be deployed for meeting room applications, while the DC9-24V terminal block is well-suited for industrial environments.
Industrial Grade Designs for High Durability and Stability
The US3344i features a series of industry-grade designs, including metal casing, M2 screw locking connector securing USB cable connection, and a robust exterior that shields against unwanted objects.
