What functionality does Toolbelt provide for Extron control products?

Toolbelt provides management and troubleshooting functionalities for Extron control products. This tool is designed to assist users in diagnosing issues with their control systems, allowing for a streamlined approach to managing these products. It can help identify problems, monitor system status, and implement solutions effectively, which improves the overall reliability and performance of the control systems.

The other functionalities mentioned in the options do not capture the primary purpose of Toolbelt. Although controlling audio and video signals is critical, that's a separate feature of Extron products themselves, not specifically linked to the Toolbelt application. Creating software for conferencing goes beyond the scope of what Toolbelt offers, as it focuses on managing existing products rather than developing new applications. Finally, while Toolbelt may be accessible via mobile devices, its functionality is not limited solely to them; it serves broader management and troubleshooting purposes that apply across various platforms.
