The R9861008NA CSM-1 Click Share Wireless Presentation System from Barco consists of two USB powered devices (with Click Share buttons) and a base unit. The base unit has a fixed connection to the meeting room's visualization system, and takes care of all the needed processing. You can simply connect a button to the PC or Mac and click the Click Share button, and immediately the desktop is wirelessly transferred to the large visualization system. Alternatively, when using a smartphone or tablet (either iOS or Android), a simple app allows you to share content as well. The system's stability and ease of use, also limits the number of needed interventions by the IT department. You can connect up to eight Click Share buttons to the CSM base unit simultaneously.
