Barco WhitepaperAbout this Network Integration WhitepaperThis guide helps you to get stared with ClickShare and deploy the ClickShare Base Units eitherdirectly out of the box or by integrating them in your Enterprise network. It contains an overviewof the security modes and offers you recommendations for Wi-Fi configuration and for usingantenna extension cables. Finally the troubleshooting sections provide you with an answer on themost common issues.Note: Typically, all ClickShare network configurations are done only once, before use. The setupshould not require any further modifications after installation.DisclaimerThe Network integration feature is provided “AS IS”, without any liability or obligation on behalfof Barco. Barco cannot guarantee that the integration mode works in your Enterprise network.The reliability, quality and stability when sharing using the network integration modes depends onyour specific network infrastructure.Deciding on and deploying one or more ClickShare Base Units within the network requires theinvolvement of your IT department, especially of the persons responsible for the configuration ofyour network infrastructure and authentication protocols.LimitationsTake into account that the ClickShare Base Unit and Button(s) cannot be used to: Access the internet or as an access point to any wired network Bridge 2 or more networks into one networkShould you have any questions, please let us know via clickshare@barco.com.P 5 / 51

Barco WhitepaperImportant notes on the ClickShare system installationA correct installation of the ClickShare Base Unit is of critical importance to ensure optimalperformance and a robust communication between the Base Unit and ClickShare Buttons, theClickShare App and mobile devices. When installing ClickShare, take into account theserecommendations: The credentials for network integration need to match the settings of the nearest Wi-Fiaccess point. Check whether the Button is connecting to your access point by verifying itspresence in the MAC address table.The Button has a MAC address starting with 00:23:A7 or 88:DA:1A.The Base Units have MAC addresses starting with 00:04:A5 on the LAN ports. To use the auto-update function for ClickShare, ensure that cs-update.barco.com leads tocs-update-prod.elasticbeanstalk.com and whitelist these IP addresses: 52.201.38.187 and52.5.31.207.Specific recommendations for Out-of-the-box use and Out-of-the-box use with Ethernet link: When setting the ClickShare up as out-of-the-box, the most favorable setup is a direct lineof sight between Base Unit and Buttons. Any obstruction will cause the signal to followa longer propagation path, possibly impacting performance. Due to the particular radiation pattern of the dipole antennas used with the ClickShare BaseUnit, the antennas should not be placed above the ClickShare users. In case of a ceilingmounted setup, the advised position for the ClickShare Base Unit antennas is at theside of the meeting room. Do not use the ClickShare Base Unit without the shipped antennas. Removing theantennas will cause severe degradation of the signal quality and may result in connectionissues between the ClickShare Base Unit and clients. Note however that CS-100 and CSE200 models have internal antennas. Place the Base Unit in an open emplacement and avoid installing in a metallicshell. A metallic shell (or even shelf) could act as a Faraday cage and block the RF signal.In case this setup cannot be avoided, please use a ClickShare rack-mounting kit or externalantennas as explained in the ClickShare application note "Recommendations for usingantenna extension cables with ClickShare Base Units". When the ClickShare Base Unit is installed, control the signal strength at the potentialClickShare Button location. For correct performance, a signal strength of at least-70dBm is necessary.For more information on the ClickShare setup, see: Troubleshooting the ClickShare setup.For more information on the wireless setup, see: Troubleshooting the wireless setup.P 6 / 51

Barco WhitepaperClickShare : secure and easy enterprise-wide deploymentClickShare (CS) is Barco's wireless presentation and collaboration system. It allows anymeeting participant to share content on the central meeting room screen at the click of abutton. Connecting ClickShare does not alter the screen size or aspect ratio: what you see onyour laptop or mobile device screen is replicated on the meeting room screen.The ClickShare CSE-range has a specific set of features to facilitate an enterprise-widedeployment, including full support for 'bring your own device' (BYOD)-users via the ClickShareApp, AirPlay and Google Cast, Touch Back support for interactivity and multi-user onscreen. The CS-100 (Huddle) Base Units support the ClickShare App, but lack the other features.The ClickShare Base Units come with enterprise-strength security that is configurable up tothree levels for the CS100 (Huddle) and CSE-range. It can be controlled via the on-premise webconfigurator or via a central asset management system (CMGS or XMS) and be fullyintegrated into your corporate network. The Base Units also offer a comprehensive API forintegration with other applications.More ClickShare support documentation at https://www.barco.com/en/supportP 7 / 51
