ATEN US434 4-Port USB 3.0 Peripheral Sharing Device
Overview
The ATEN US434 is a 4-port USB 3.0 peripheral sharing switch that lets four computers share a single USB device — a scanner, printer, storage drive, or capture device — without unplugging and re-plugging cables. Selection is handled by a remote port selector with a 1.8 m cable, so operators can switch the active computer from across the desk or through a rack-panel cutout without touching the unit itself. This is the right fit for security control rooms, imaging workstations, or operations desks where multiple machines need occasional access to one shared USB peripheral and a full KVM switch is more than the job requires. The US434 supports optional bus power via a USB Micro-B female port, keeping the install clean when a dedicated power source is not available.
Compatibility
The US434 works with any USB 3.0 or USB 2.0 host — Windows, macOS, and Linux systems are all supported provided the OS recognizes the connected peripheral natively. It is compatible with the broad range of USB-class devices: storage (HDD, SSD, flash), printers, scanners, card readers, and USB-connected ATEN peripherals. It integrates naturally into USB peripheral sharing setups in rack-mount environments — the rack-mount form factor keeps it seated alongside other 1U/2U equipment without floating cables. For environments already using ATEN KVM infrastructure, the US434 complements existing ATEN KVM switches by handling peripheral sharing independently on the USB layer. If your deployment requires simultaneous keyboard, video, and mouse sharing in addition to peripheral switching, pair with a dedicated KVM switch rather than relying on this unit alone — the US434 handles peripheral sharing only, not display or HID control.
Installation Notes
Operating humidity is rated 0–80% RH non-condensing — suitable for conditioned server rooms and control rooms, but not uncontrolled outdoor enclosures or environments prone to condensation. The remote port selector cable extends 1.8 m, so plan cable routing before mounting; this is fixed length and not field-extendable. Optional power via USB Micro-B keeps the install flexible, but confirm the host port can supply adequate current if bus-powering downstream devices simultaneously. For rack-mount installations, ATEN notes that physical dimensions on select rack products follow an L×W×H convention rather than the standard W×D×H — verify orientation in the rack before ordering panel blanks or cable managers.
