Bi-directional USB-C Switch

The LUOM TJ-A034 is a bi-directional USB-C switch that operates as either a 2-in-1-out KVM or a 1-in-2-out splitter. It lets users toggle between two source devices on one display or route a single source to one of two monitors. Only one output is active at a time. It targets professionals who share a high-resolution screen between a laptop and a workstation.

Passive Operation With External Power

The unit draws no power from the host ports for its switching logic; a supplied Micro-USB cable must feed the side DC input before any video appears. Video bandwidth reaches 10 Gbps and supports 8K at 30 Hz or 4K at 120 Hz. Up to 100 W of USB Power Delivery passes through to charge a connected laptop while the link is active.

50 cm Tether And Manual Select Button

A fixed 50 cm USB-C tail plugs directly into the display, removing one cable from the desk. A tactile Select button on the housing switches the active channel instantly without software. The package includes the Micro-USB power cable only; two USB 3.1 Gen 2 cables for the sources are not supplied.

Questions about this item

How do I install the LUOM TJ-A034 and which step is often missed?

Connect two USB 3.1 Gen 2 cables from your source devices to the switch ports USB-C 1 and USB-C 2, attach the fixed 50cm cable to a monitor USB-C port that supports video, plug the supplied Micro-USB power cable into the switch, then press the Select button. The external power step is mandatory or no image appears.

What maintenance or replacement will the LUOM TJ-A034 need later?

No user-serviceable parts exist inside. If the fixed 50cm cable or the Micro-USB power lead frays, replace the whole unit. Keep the Select button free of dust so switching between the two sources remains reliable.

What limit appears first during sustained use of the LUOM TJ-A034?

The single-monitor design means only one of the two connected displays can be active at a time. Bandwidth caps at 10 Gbps, so 8K@30Hz or 4K@120Hz is the ceiling, and the 100 W PD limit stops higher-power laptops from charging fully.
