ATEN VS0104 4-Port VGA Switch with RS232

Keep multi-source VGA environments organized and controllable. The ATEN VS0104 switches between four VGA inputs and adds RS232 control, giving integrators a practical way to manage source selection from a control system, touch panel, or automation platform. This is the kind of device that earns its place in a rack because it removes friction from daily operation. Instead of walking to the display chain or re-cabling sources, operators can switch inputs through a controlled interface. That matters in classrooms, meeting rooms, training spaces, and technical labs where uptime and repeatability are more important than consumer convenience. ATEN builds for installations that need predictable behavior and straightforward integration. The VS0104 is a focused switching component, not a feature-heavy box trying to do everything. That restraint is valuable in professional AV systems: fewer variables, easier commissioning, and a cleaner path to long-term support. For teams standardizing on reliable signal routing, it provides a compact way to manage four VGA sources with serial control in one purpose-built unit.
