Bring ClickShare wireless collaboration into a meeting room with a complete Hub Pro configuration. The R9861820US package combines the ClickShare Hub Pro, a CAT extender and two ClickShare Buttons in one TAA configuration. It provides two dedicated Buttons for users initiating ClickShare collaboration from the meeting table. The included CAT extender is supplied for room configurations that require CAT-extension hardware alongside the Hub Pro system. Two Buttons suit smaller meeting spaces and shared rooms where more than one presenter may need immediate access to the ClickShare workflow. Keep the extender and Button count in scope when matching this kit to a room design. Select this kit when the required system is specifically ClickShare Hub Pro with a CAT extender, two Buttons and TAA designation. It fits fixed meeting-room collaboration installations that need this defined Hub Pro package rather than an unspecified ClickShare component. The two included Buttons distinguish the package for rooms needing two user-control devices; assess display, network, control and conferencing requirements separately.
