ATEN UH3235 USB-C 4K Ultra Mini Dock with Power Pass-Through
Overview
The ATEN UH3235 is a compact USB-C docking accessory that extends a single laptop or workstation connection into a multi-output hub while passing power through — useful in space-constrained deployments where a full docking station is impractical. The UH3235 connects via a 50 cm integrated cable, keeping the unit close to the host machine and reducing desk clutter on ATEN-integrated workstations or compact operator consoles. The top supported video output is 3840×2160 at 30 Hz, meaning 4K monitors are supported but at 30 fps — adequate for static or near-static display work such as monitoring dashboards, but not suited for high-frame-rate video playback.
Compatibility
Designed for hosts with a USB-C port that supports DisplayPort Alt Mode and USB Power Delivery. Compatible with USB-C equipped laptops, compact PCs, and workstations commonly deployed alongside KVM switches and console management setups. Power pass-through support depends on the host's USB-C PD negotiation capability — confirm your host supports USB-C PD before relying on pass-through charging. Not suitable for hosts with USB-C ports limited to data only (no DP Alt Mode). For rack-integrated deployments, note that ATEN documents this product under rack mount guidance: physical dimensions follow an L×W×H convention rather than the standard W×D×H format.
Installation Notes
The 50 cm cable length is fixed — position the dock within direct reach of the host USB-C port. Operating humidity is rated 0–80% RH non-condensing; avoid installation in environments with condensation risk such as unventilated server closets or outdoor enclosures. Firmware v1.0.004 (released 2023-05-02) is available for this unit — confirm the installed firmware version matches current release before deployment in managed environments where firmware consistency is enforced across USB connectivity accessories.
