Control multiple systems from one workspace with one keyboard and mouse set

Control rooms operators must monitor information coming from multiple different systems, each with its dedicated set of keyboard and mouse. A more seamless multi-system control is crucial for improving the operator’s response time and workspace ergonomics. With Matrox KMLync, operators can work across a larger multi-monitor workspace, controlling up to four separate systems using a single keyboard and mouse pair to switch between systems using seamless mouse technology or on-device buttons. Additionally, KMLync requires no software installation on the host system, so IT administrators can enjoy the benefits of fast setups and hassle-free maintenance. Matrox KMLync is TAA compliant.
