Eight-computer VGA control

The SV831DUSBAU lets one keyboard, mouse and monitor manage eight USB-equipped computers through VGA video and stereo audio. It is aimed at server-room administrators and lab technicians who need single-console access to multiple legacy or rack-mounted systems.

Rack-mount setup with cable management

The 1U chassis fits a standard 19-inch rack and ships with sixteen 6-foot audio cables plus a power adapter. Installers must match each green and red mini-phone plug to the correct computer port; misaligned audio channels are the most common wiring error.

Steady switching under continuous use

Video holds at 1920 x 1440 across all eight ports without signal degradation during extended sessions. The unit draws power from the external adapter rather than host USB ports, so console responsiveness remains stable even when several connected machines are under heavy load.

Questions about this item

How do I confirm the SV831DUSBAU is switching correctly after rack installation?

Connect the console keyboard, mouse and monitor to the front HD-15 and USB ports, attach up to eight computers using the supplied 6 ft green and red audio cables, then press the front-panel port selector; the active port LED lights and the selected computer's video appears at 1920 x 1440 resolution.

Which cables and accessories ship with the SV831DUSBAU and what must I source separately?

The box contains the 1U rack-mount switch, a power adapter, eight 6 ft green audio cables and eight 6 ft red audio cables; you must provide VGA cables for each computer and a VGA cable for the console monitor.

The SV831DUSBAU supports eight computers — should I choose this model or a smaller version?

This specific model provides eight computer ports; if you need fewer connections, a different StarTech model with a lower port count would be required.
