The combiner can cascade to combine multiple units and scale control to larger multi-system setups. Power is supplied internally with a maximum power consumption of 35W.

Connectivity is broad and flexible – each computer port accepts DisplayPort or HDMI video and provides USB Type B for keyboard and mouse control. The console side uses USB Type A for HID devices and USB 3.0 Type A for high-speed peripherals. Supported operating systems include Windows, Linux and Mac to ensure broad compatibility with common workstation environments.

Typical applications include control rooms, trading desks, AV operation centers and broadcast monitoring where users must view and interact with multiple isolated systems.
