This SMA switch lets you operate two USB-C laptops or desktops from a single keyboard, mouse and HDMI monitor. Each host connects with one cable that carries video, data and up to 60 W of charging power. No driver installation is required on Windows 10, 7, 2000, XP or macOS 10.6.2 and later.

Passive Cooling and 60 W Delivery

The unit has no fan and draws no external power beyond what the two USB-C PD 3.0 ports supply at 5 V, 9 V, 15 V or 20 V. Both connected computers can charge simultaneously at the full 60 W while the switch passes 4K 60 Hz video through its HDMI 2.0 output.

Metal Enclosure With Remote Button

A compact metal chassis houses two USB-C upstream ports, three USB 2.0 downstream ports and separate audio and microphone jacks. Switching is done by a front-panel button or the included 39-inch wired remote; hot-key switching is not supported. The box ships with two 31-inch USB-C 10 G cables and the remote cable.

Questions about this item

How do I set up the KVM with the two 0.8 m USB-C cables and the 1 m remote switch?

Connect each computer to a USB-C port on the KVM using the supplied 0.8 m cables, plug the monitor into the HDMI output, then plug the remote switch into the dedicated port on the KVM; press the remote or the front button to change computers.

What ongoing upkeep does the 60 W Power Delivery circuit need?

No scheduled maintenance is required; keep the USB-C connectors clean and ensure the PD chargers stay firmly seated so each computer continues to receive up to 60 W at 5 V, 9 V, 15 V or 20 V.

At what point does the HDMI 2.0 link become the bottleneck during long sessions?

The HDMI 2.0 output caps video at 3840×2160 at 60 Hz, so sustained work at that resolution runs at the link's maximum bandwidth without further headroom.
