Extron LinkLicense (part number 79-2546-01) — the User Interface Upgrade for Extron HC 400 Series Meeting Space Collaboration Systems. This is a software license, not a hardware device.

An HC 400 Series room already handles display power, source switching and volume on its own, and it accepts a TouchLink Pro touchpanel or an NBP Network Button Panel as a physical interface. What this license adds is a software one: with 79-2546-01 applied, a phone, tablet or laptop on the network can act as the room's primary control surface. That matters in spaces where no wall real estate is available for a panel, where users prefer their own device, or where an existing room needs another interface without new cabling or hardware.

Key Capabilities

• Enables mobile devices and computers to drive HC 400 Series AV system functions.
• A single part number, 79-2546-01, is listed against every HC 400 Series configuration.
• Applies to the HC 404, HC 403, HC 402, HC 402 EU and HC 402 MK systems.
• Works alongside, not instead of, TouchLink Pro touchpanels and Network Button Panels.
• Delivered as a license; nothing is rack mounted, powered or cabled to deploy it.

Where It Is Used

Huddle rooms, small and mid-size conference rooms, classrooms and training spaces already standardized on the HC 400 Series — particularly where the organization wants bring-your-own-device control, or where a rollout needs a consistent control experience across many rooms without buying a panel for each one.
