5 SERVICE AirMedia Deployment Guide Introduction The AirMedia (AM-100) Presentation Gateway allows users to present their content via projectors and displays using the existing IT infrastructure without connecting wires. It is a small network device with a single 10/100 mbps Ethernet port. Windows and OS X users can share their desktop by running a small application (no installation required). ios and Android TM users can share Excel, Word, PowerPoint, PDF files, photos, and other content by using the free application available from the App Store and in Google Play TM. Because of its reliance on Ethernet, AirMedia has been designed with the IT professional in mind and includes many features to ease deployment. This document provides information on AirMedia operation, user access, security, and control systems. For more information, refer to the AirMedia Quickstart Guide (Doc 7464) and AirMedia Operations Guide (Doc 7463) at Simple AirMedia Deployment Example OPTIONAL CONTROL SYSTEM WIRELESS ACCESS POINT L A N LAN LAN OR HDMI 5V 2.5A L A N HDMI Color Key HDMI LAN Doc. 7693D crestron.com 1

6 User Experience On-Screen Display AirMedia uses an on-screen display to convey the basic connection instructions for guest access. The display can be personalized to allow custom login instructions and branding. It provides the hostname, IP address (optional), and login code for the specific AirMedia device. Login Code A login code is provided to help prevent users from accidentally connecting to an unintended device. The user begins the connection process and is prompted to enter a code in the Login window. The code is only four digits, so it is easy for the user to enter while still preventing unwanted presentations. Login Window There are three modes of operation: 1. Disabled: A login code is not required. 2. Random: A login code is generated after the last user disconnects. 3. Fixed: A login code is set using the web administration pages (static) or using a control system to update programmatically. Connecting to AirMedia Crestron provides two ways to connect to the AirMedia device using a PC: 1. Guest Application: Connect to AirMedia using either the Windows or the OS X guest application. The guest application is downloadable from the AirMedia device. 2. Deployable Application: Access the deployable stand-alone application at The guest and installed applications are compatible with the operating systems shown below. Operating System Windows OS X Versions Supported Windows XP, Windows Vista, Windows 7, and Windows 8 operating systems 10.5 and newer 2 Doc. 7693D crestron.com

7 Guest Application The guest application is a small downloadable application that runs with standard user permissions. The IP address of the AirMedia device is encoded in the filename of the application. The user may save the application locally, which allows for direct connection to the device the next time the application is accessed. Accessing the Guest Application To access the guest application from the AirMedia Welcome window, complete the steps below: AirMedia Welcome Window 1. Open a web browser and enter the user's IP address or hostname into the browser. The AirMedia Guest Download window opens. AirMedia Guest Download Window 2. Click Download for Client for Windows or Client for Mac. A small application is downloaded; the user runs the application. If prompted, enter the login code. The session begins. The user s desktop is shown on the on-screen display. Doc. 7693D crestron.com 3

8 Guest Application Executable The guest application can be downloaded and saved for custom deployments, such as to websites or other media. The connection parameters for the guest application are embedded in the file name. The format is as follows: <any_text>_.<ip_address>.exe. NOTE: The underscore and dot must precede the IP address. Refer to the following example: executive_conference_room_ exe. Deployable (Installed) Application A deployable stand-alone application can be deployed to users computers across the enterprise. This application allows other types of connections to the AirMedia device and has no registry requirements. The application can be silently deployed as a group of files to a folder on the users' computers. The enterprise application can be downloaded at Managing the rooms in which AirMedia is installed can be a significant task. There may be multiple campuses or rooms that only certain employees can access. To address the various deployment scenarios, AirMedia has four methods to access the connection parameters of a room. 1. Room Lists: The AirMedia client application reads the XML file containing a list of rooms and presents them in a searchable list as shown in the Available Remote Box List window. Available Remote Box List Window 2. File Association: The AirMedia client application is associated with.present files. These files can be embedded in meeting invites or hosted on a corporate website. 3. Discovery: If the AirMedia devices and the user s computer are on the same subnet, the AirMedia client application locates these devices and presents them to the user. This method is recommended if a room list or.present file is not used. 4. Manual Entry: AirMedia allows the user to enter the hostname or IP address of the device. 4 Doc. 7693D crestron.com

9 Room Lists The application reads a list of devices and populates the connection dialog. A search box is provided to locate devices in long room lists. To connect using a room list, complete the steps below: 1. Launch AirMedia. 2. From the Available Remote Box List window, select the room from the list of devices. Available Remote Box List Window 3. Click Connect. If prompted, enter the login code. If a Crestron Connected display is used, the display turns on automatically. The session begins. 4. Create two files: config.ini and XML. The config.ini file provides the location of the list of rooms (XML file) to the AirMedia application. This file must be in a fixed location. For more information, refer to "Configuration File (config.ini)" below. The XML file should contain the list of AirMedia devices. For more information, refer to the "Device List File (XML file)" on page 6. Configuration File (config.ini) Crestron uses the common repository for user specific data on Windows and OS X to store its config.ini file. Windows refers to this as the application data folder, and it can be accessed by the environmental variable %APPDATA%. For OS X, the preferences are stored in the user s home directory under Application Support. For both operating systems, the configuration file must be located within Crestron\AirMedia in the common repository. Examples of typical user directory locations (which vary) for Windows 8 and OS X are shown below: User Name: TestUser Windows 8: C:\Users\TestUser\AppData\Roaming\Crestron\AirMedia OS X : /Users/TestUser/Library/Application Support/Crestron/AirMedia/Configure After the folder is created, the configuration file must be created. The config.ini file contains the location of the room list file. The file contains two items: the section Crestron and the key XMLPath. An example of a config.ini file is shown below. [Crestron] XMLPath=M:\config\airmedia\room_list.xml When the AirMedia application starts, it attempts to read the file at the location specified by the XMLPath. Local and network paths are allowed. Do not enclose the path in quotes. Environmental variables are not supported. Doc. 7693D crestron.com 5

10 Device List File (XML file) The room list file is an XML file that defines the devices and their connection parameters. The specifics of the file are defined below. Tag Description Example devices device name address code This is the main container for the device list file. Each file must contain only one set of tags. This is the container for each device to be displayed. The file may contain one more set of tags. This is the display name for the AirMedia device that is shown in the Device Name column of the application. This is the IP address of the AirMedia device. This field is currently limited to IPv4 addresses only. This tag is used to limit access to AirMedia and can be disabled, randomly generated, or fixed to a specific value. In fixed mode, the code tag may be used to specify the access code. <?xml version="1.0"?> <devices> <device> <name>room 239</name> <address> </address> <code>5885</code> </device> <device> <name>room 240</name> <address> </address> </device> <device> <name>room 241</name> <address> </address> </device> </devices> File Association The.present files contain the connection parameters and start a connection. These files can be hosted by a web server or deployed to folders within the user s computer. The association is made by the installer. To connect using file association, complete the steps below: 1. Double-click a.present file. The application launches. 2. If prompted, enter the login code in the Login window and click Connect. The session starts. Login Window NOTE: If a Crestron Connected display is used, the display turns on automatically. A.present file is a set of connection parameters to a single AirMedia device. It uses the same format as the device section of the room list file. An example of the.present file is shown below. <?xml version="1.0"?> <device> <name>room 239</name> <address> </address> <code>5885</code> </device> 6 Doc. 7693D crestron.com

11 Discovery If a room list file is not found when AirMedia is started, the application scans the local subnet for connection devices. If only one device is found, the application tries to connect to that device. If multiple devices are found, the application displays a list of connection devices. From the Available Remote Box List window, select the Device Name and IP address and click Connect. Available Remote Box List Window Manual Entry If the application is unable to find any devices, the Login window (for manual connection) opens. Enter the IP address or hostname of the device, User Name, and Code, and click Connect. Login Window Doc. 7693D crestron.com 7

12 Device Considerations Device Naming The use of IP addresses can cause confusion; therefore, Crestron recommends that each AirMedia device be given a hostname that is easy for the user to remember. The IP address can be hidden from the on-screen display, which limits the amount of information presented to the user. Crestron has implemented the following automated ways of resolving the device by hostname: NetBIOS resolution DHCP options 12 and 81 NSUPDATE for dynamic DNS servers Crestron recommends configuring a static IP and DNS entry for the AirMedia device. Once the hostname is configured, the IP address display can be turned off in the Device Setup section of the AirMedia web pages. NOTE: NetBIOS is used only if the hostname is 15 characters or fewer. NetBIOS is disabled if the hostname is longer than 15 characters. NOTE: NSUPDATE is sent under the following conditions: If the device is using a static address and the DNS field is populated If the device is using DHCP to obtain an IP address, and the Domain Name field in the Network Setup screen is not blank If the domain name field is blank, NSUPDATE is not sent. Device Administration AirMedia is configured through the built-in web pages of the device. Parameters such as the device IP address, remote view settings, connections to control systems, and Crestron Connected devices are set in the Device Administration window. The default password is admin, which can be changed. Device Administration Window with Network Setup Selected 8 Doc. 7693D crestron.com

13 Firewall Rules The AirMedia application requires firewall rules to allow it to communicate with the AM-100 device. Crestron recommends creating a rule for the application that allows all traffic to pass to the device. If the rule does not exist, the operating system prompts the user to add a rule. This may require administrator privileges. Refer to the Port Map 1: Ports Used by the Client table for the set of ports that allow the client to communicate with the device. Port Map 1: Ports Used by the Client Port Type Direction Function Open Notes 80 TCP Both Projector Control TCP Both Control Channel Optional Required This port is used to turn on a Crestron Connected projector. If this port is blocked, the device functions normally, but the "automatic projector power on" feature does not work. For best performance, Crestron recommends that ports 389, 443, and 445 are open. At a minimum, one port needs to be open for the device to function properly. If only one port is open and that port is used by another application, AirMedia will not function properly. 515 TCP Both Video Required This port is for the video data channel TCP Outbound Control Channel Required If this port is not open, AirMedia does not function properly. UDP Inbound Discovery Optional These ports are used for device discovery. If the port is closed, AirMedia may not be able to find devices automatically TCP Both Audio Recommended This port is for the audio data channel TCP Both Control Channel Required This port is used as part of the screen sharing process TCP Both Video Required This port is for the video data channel. If the port is not open, AirMedia does not function properly TCP Both Future Optional This port is reserved for future use TCP Both Discovery Optional This port is used for device discovery. If this port is closed, AirMedia may not be able to find devices automatically. Doc. 7693D crestron.com 9

14 Refer to the Port Map 2: Ports Used by the Device (AM-100) table below for the ports that the AM-100 uses only for management functions. Port Map 2: Ports Used by the Device (AM-100) Port Type Direction Function Open Notes 21 TCP Both Update Utility Optional This port is used to transfer the firmware to the device and is used only with the batch update application.

15 Mobile Applications Connecting Crestron offers applications for both ios and Android to allow users to give presentations using their mobile devices. Applications are available at no cost from the itunes App Store and on Google Play (search for AirMedia). The application connects to AirMedia devices by discovering them or when the IP address or hostname of the device is entered. Connected devices are saved to allow for easier future connection. A search function is provided to quickly navigate long lists. AirMedia devices can be marked as favorites for quick connections to frequently used rooms. The Crestron AirMedia for ios window is shown. Crestron AirMedia for ios Window Future Development The user support of room lists and.present files is planned and will be released through a free update. Doc. 7693D crestron.com 11

16 AirMedia Security AirMedia has been designed to leverage existing IT policies. AirMedia contains a single-wired network interface with no wireless interfaces or bridges in the device. It becomes a wireless solution by utilizing the existing wireless network. All policies, encryptions, and other security measures implemented carry over to AirMedia because it creates standard Ethernet traffic. Once AirMedia is on the corporate network, the traffic generated by AirMedia is treated like any other network traffic. All existing policies that apply to physical network devices (switches, routers, etc.) also apply to AirMedia. AirMedia can be treated as a standard network appliance (like a printer) and is as secure as the supporting network. AirMedia employs a proprietary protocol to transport the screen data to the device. Deployment Options for Guest Network Access In meeting rooms, guests may want to present to corporate users. Keeping the guest networks and corporate networks separate while allowing the users to share a display presents a challenge. As a standard network device, AirMedia solves this problem by using standard networking practices. There are two suggested methods: VLAN based method and physical air gap method. VLAN Based AirMedia devices are placed in their own VLAN. This VLAN is configured to allow only incoming connections. Outbound traffic is not allowed. The guest and corporate networks exist in separate VLANs. Since outbound connections are not allowed, the guest VLAN cannot access the corporate VLAN through the AirMedia VLAN. AirMedia VLAN Based Method Example WIRELESS CONNECTION SECURED USING ENTERPRISE POLICIES WIRELESS CORPORATE USER WIRELESS ACCESS POINT WIRELESS CORPORATE USER WIRELESS ACCESS POINT WIRELESS GUEST USER CORPORATE SERVER Corporate VLAN Guest VLAN WIRELESS GUEST USER AIRMEDIA VLAN ACCEPTS ONLY INCOMING CONNECTIONS AirMedia VLAN WIRED CORPORATE USER Color Key HDMI Ethernet Room 1 TV AirMedia AirMedia Room 2 TV 12 Doc. 7693D crestron.com

17 1 2 SETUP NET AirMedia Deployment Guide Physical Air Gap The corporate and guest networks are separated by a physical air gap, and two AirMedia devices are used: one for corporate users and one for guest users. Switching presentations is done in the HDMI domain using a 2 x 1 matrix switch. While extremely secure, this approach requires more hardware.

18 Data Transport AirMedia employs a proprietary protocol to transport the screen data to the AirMedia device. The data is encrypted based on the four-digit code displayed on the on-screen device (OSD).

19 Network Infrastructure AirMedia s bandwidth requirements are low, falling well below 1 mbps. However, if a user is showing a video or other application with motion, the bandwidth required could be as much as 35 mbps. For the best performance, the latency between the user s computer and AirMedia should be minimized. The best performance is seen with less than 50 ms round-trip time. PowerPoint, Word, Windowed Video, and Full Screen Video use cases are presented in this section. PowerPoint Presentation Use Case The most common use case for AirMedia is using a productivity application such as Microsoft Office. In this case, small bursts of data are sent during connection and for large screen changes, such as changing from the desktop to the full screen Start menu in Windows 8. The illustration below shows the bandwidth consumption associated with launching the PowerPoint application and delivering a presentation. The PowerPoint presentation consists of mostly white slides with text. The exceptions are slide 1 (full screen graphic) and slide 6 (one-third of the screen graphic). Data are in bits per second. PowerPoint Bandwidth Example Doc. 7693D crestron.com 15

20 Word Document Use Case The illustration below shows the network usage when working with a large text document in Word. A "Find and Replace" was performed, and the user scrolled through the window, producing a moderate amount of motion. Data are in bits per second. Word Bandwidth Example 16 Doc. 7693D crestron.com

21 Windowed Video Use Case The illustration below shows how AirMedia's network requirements increase significantly when there is video displayed. The constantly changing images require a significant amount of data to be transferred. The video below is in a 702 x 422 window. The average bandwidth used when the video was playing was 9.7 mgb per second. Data are in bits per second. Windowed Video Bandwidth Example Doc. 7693D crestron.com 17

22 Full Screen Video Use Case The illustration below shows a full screen video. The video (waves breaking on a rock) is difficult to compress. This represents the worst-case scenario for an AirMedia device. In this case, the device consumes 32 mgb per second. Data are in bits per second. Full Screen Video Bandwidth Example 18 Doc. 7693D crestron.com

23 Device Upgrades Single Device (Web Interface) The AirMedia device supports firmware upgrades via the web interface. Upgrades are deployed as a single file, which is uploaded and programmed by the device. Upgrades take from 15 to 30 minutes to load. Multiple Devices Crestron provides an application to upgrade multiple AirMedia devices. The application reads room list files to simplify management. Devices can be upgraded one at a time or in a batch operation. To upgrade the AirMedia devices, the user needs to connect to an FTP server. The application provides an FTP server for convenience, or AirMedia can also be configured to use an external FTP server. The application is available on the Crestron website at Control Crestron Connected AirMedia can control any Crestron Connected display. When the application is launched, a "power on" command is sent to the display. This means no more searching for remote control devices or pressing the power button. The user provides the AirMedia device with the display's IP address, and AirMedia begins controlling the display. During connection to AirMedia, a command is issued to turn on the display. After the last user disconnects, AirMedia automatically turns off the display. For more information on Crestron Connected devices, refer to the Crestron website. Control System AirMedia can integrate with Crestron control systems for complete room control. When a control system is used, the complete room can be controlled to include lights, display, HVAC, shading, and anything else in the room. In addition, the control system can implement Simple Network Management Protocol (SNMP) to integrate with existing IT management tools. The device parameters can be set and monitored using a Crestron control system, shown in the "Device Parameters" on page 20. Doc. 7693D crestron.com 19
