Extron
Extron eBUS button panels are customizable, easy-to-integrate AV system control interfaces designed for use with Extron IPCP Pro control processors.
These panels are available in industry standard sizes and allow multiple units to be connected with a single cable that carries both power and communication. In addition, your buttons can be easily customized using Extron's Button Label Generator software or using the online Custom Button Builder application.
All eBUS button panels have two eBUS ports for easy system expansion and upgrades. Because the panels share a control processor and are connected with a single cable, they can be distributed with multiple configurations or topologies that best suit your application and environment. The total wiring distance of any configuration should not exceed 305 m (1,000 ft).
