4.1 4.2 4.3 WiJET.Video Technical Manual Page iii of 29 Chapter 1:

INTRODUCTION The OTC Wireless Projector and Monitor Adapter with Motion Video, WiJET.Video is an IEEE 802.11g compliant product designed specifically for wirelessly connecting projectors and monitors to computers. It connects to the existing VGA connector of the projector/monitor and offers 802.11g connectivity up to 54 Mbps. The advantages of the WiJET.Video become obvious in any conference room where the ideal location of the projector or display screen makes it difficult for a laptop or desktop to connect to it while allowing the speaker to maintain audience interest. All too frequently, projectors placed in the middle of the room force the speaker to present from the middle of the room, because of the VGA cable that exists between the projector and the presenters laptop. The WiJET.Video solves this problem by allowing any laptop or desktop with an 802.11g Wi-Fi adapter to give the presentation from anywhere in the conference room that the presenter desires. Wherever the presenter feels would garner the most amount of interest from the audience. Truly freedom from wires allows for more flexibility in meetings. Another application of the WiJET.Video is in a situation where multiple presenters must give presentations in rapid succession. The WiJET.Video allows for fast handover of the projector or monitor without the hassle of removing and reattaching the VGA cable. Using the easy-to-use Presentation Session Manager, the presenters can effortlessly connect to the WiJET.Video, give a presentation, and disconnect from the WiJET.Video to allow another user to connect to it without touching a single cable. A third application that showcases the advantages of the WiJET.Video is where there are multiple conference rooms with multiple projectors. A WiJET.Video in every conference room will substantially save setup time when the presenter comes into the room. The presenter only simply selects the WiJET.Video number displayed on the projector/monitor screen and he is instantly connected to the projector and able to start his presentation. This removes a lot of setup time associated with presenters moving from room to room to give their presentations, ultimately saving IT costs. In summary, the WiJET.Video is a tool that will change how people come to view conferences and meeting rooms. Instead of a static meeting place, the conference rooms can now become a dynamic meeting place where new thoughts and ideas are exchanged and created.

Warning: use only the power supply adapter provided with this product or the manufacturers authorized replacement power supply. 2.2.2 VGA Connection This is a standard 15 pin female VGA connector where you will connect the WiJET.Video to either a monitor or a projector via a straight-thru monitor cable (either purchased separately or with the one that comes with the projector or monitor). 2.2.3 Video Output Signal Connections WiJET.Video provides an S-Video connection. Regular S-Video cable can be used to connect with an S-Video input on a TV or projector. Special cables may be ordered to connect to composite video or component video inputs. 2.2.4 Status LEDs There are two status LEDs on the WiJET.Video. From the front of the unit, the LED on the left is the power indicator while the LED on the right is the link status and video out indicator. During boot-up, the link status LED will initially remain unlit. When the link LED blinks red, it means the WiJET-G is ready for connection to a PC. Upon connection from a computer, the LED will turn solid green. Upon disconnection, the LED will revert to blinking red again. 2.2.5 Reset to Factory Default WiJET.Video provides a pin-push button to the side of the unit. Press this button for a second to reset the WiJET.Video back to the factory default setting. The unit will reboot. Normally, this should only be done when you forget the Web password or when the WEP keys have become incompatible with the wireless card on your PC. WiJET.Video Technical Manual Page 3 of 29 Caution: Please note that resetting the product to its factory default means losing all configurations and encryption information you may have set through the web interface!

2.3 User Software Installation The following details the steps involved in installing the software needed to control the WiJET.Video. 2.3.1 System Requirements for User Software To use the WiJET.Video user software, your computer must meet the following requirements. Wi-Fi or IEEE 802.11g enabled computer (either built-in or add-on NIC);

Windows 98/NT4/ME/2000/XP; and Minimum equivalent processing power of Pentium 3 at 750 MHz and 64MB of RAM. Installation for the WiJET.Video Presentation Session Manager (PSM) 2.3.1.1 This step is optional and can be skipped for those who simply want to run WiJET.Video Presentation Session Manager (PSM) without the administration capability. PSM can be executed on CD-ROM without being installed to the local hard drive. To install the WiJET.Video software on your local hard drive, insert the Installation CD in your computers CD-ROM drive. A Selection window would automatically start and the user can choose to run the PSM from CD-ROM or to install the PSM onto the local hard drive. If the program does not automatically start, go to My Computer and double click on the Installation Disc icon. Click on WiJET.Video.exe once you can see the CDs contents. Simply follow the instructions from the installation process to install the PSM software once the installation program starts running. 2.3.1.2 Installation for the WiJET.Video Administration Manager To install Administration Manager, explore the WiJET.Video CD in the CD-ROM drive and enter the admin folder. Click on setup.exe in the admin folder and follow the instructions for installation of Administration Manager. For instructions on using the Administration Manager, please see Chapter 4: Using the Web-served Administration Application. 2.4 System Requirements for Web-served Administration Application WiJET.Video has a Web-served Administration Application that can be used to configure the settings of the product. The Web-based Administration Application can be accessed through WiJET.Video Administration Manager. To use the Web-served Administration Application, the computer must meet the following requirements:

(1) A Web browser must be installed on the computer. The supported Web browsers include Internet Explorer 5.0 and above, Netscape 6.0 and above, Mozilla 1.0 or above and Opera 6.05 or above. JavaScript for the browser must be enabled. WiJET.Video Technical Manual Page 4 of 29

(2) IEEE 802.11g or Wi-Fi enabled computer (either built-in or add-on NIC). See Chapter 4: for detailed information on how to configure the WiJET.Video using Web-served application. WiJET.Video Technical Manual Page 5 of 29 Chapter 3: USING WiJET.Video 3.1 Using the WiJET.Video in a Meeting In addition to the obvious convenience with wireless connection, the most important benefit of eliminating the VGA cable in using presentation projectors or monitors is to enable fast handover of the projector or monitor control among multiple meeting participants. The Presentation Session Manager (PSM) provides a simple user interface allowing quick rotation of presentation among multiple presenters. The following simple steps sketch out how a successful Wireless Presentation Meeting unfolds:

1. Copies of the WiJET.Video installation CD are kept with the product in the meeting room. The meeting host, before the presentations start, identifies the meeting participants who do not yet have the Presentation Session Manger installed on their computers and hands them the installation CDs. The participants can either run PSM from the CDs or install the PSM onto their system. The installation is automatic and does not require rebooting the computer. 2. The meeting host asks all meeting participants to establish a wireless connection to the product before the meeting starts. Most participants can accomplish this by clicking just one button. This wireless connection is kept alive throughout the meeting even if only one presenter can use the projector or monitor at a given time. Confirming wireless connections before the meeting starts assures a smooth presentation session. 3. At any given time, by clicking just one button in the PSM, one designated presenter can start the presentation and exclude other presenters from using the projector/monitor. 4. At the click of one button in the PSM, the incumbent presenter yields the floor

(the projector/monitor) to another presenter while still maintaining a live wireless link to the WiJET.Video. 5. At the click of one button in the PSM, a waiting presenter, owing to the already established wireless link, can instantaneously take over the projector/monitor. The normal meeting etiquettes have to be followed to determine how the control of the projector/monitor should be rotated among presenters. The WiJET.Video and its PSM make the rotation easy and quick and thereby make the meeting dynamic. WiJET.Video Technical Manual Page 6 of 29 3.2 Starting the WiJET.Video When the product is first turned on, a boot up sequence will follow. After about 30 seconds, the unit will display the following graphic (Figure 3.1) with a few informative messages. Figure 3.1 WiJET.Video Banner Page The messages will be displayed on the top of this image and consist of two lines. The top line displays the SSID and the channel number of the unit while the second line reports on the channels currently in use by other 802.11g equipment around the unit. An example of the messages is given below:

SSID=WiJET.Video0001 Channel=6 RF activities detected on other channels (none). There are several variations to the message on the second line. The variations and what they mean are as follows:

RF activities detected on other channels (none). No other 802.11g/b channels detected in use other than the WiJET.Video at all. Your connection to the unit should be smooth and error free. WiJET.Video Technical Manual Page 7 of 29 RF activities detected on other channels (8, 9). Existing 802.11g/b channels detected in use, but there is no interference. Your connection to the unit should be smooth and error free. RF activities detected on other channels (1, 5, 8, 11). WARNING:

Interference. Existing channels detected and interference found. The unit is in a RF noisy environment, you may have trouble connecting and maintaining connections to the unit even if a connection can be made. Note:

WiJET.Video updates this information whenever the banner page appears. In a noisy environment, channel information might get outdated quickly since the product does not monitor channels continuously. Once you have turned the WiJET.Video on and noted the above information, you can now configure your computer to connect to the unit. 3.3 Configuring Computer to Control WiJET.Video Before starting the Presentation Session Manager, the network interface of the computer must have a valid IP address. For computers running DHCP client mode while DHCP server is unavailable, it may take a few moments for the computers to obtain a system IP address. If users cannot obtain a valid IP address for the network interface, please refer to any network administration references for how to assign IP address to a network interface/connection. NOTE:

The computers network interface must have a valid IP address before PSM starts. 3.4 Starting Presentation Session Manager You have to start the Presentation Session Manager (PSM) to control the WiJET.Video unit. There are two ways to run the PSM. One is to run the PSM directly from the utility CD while the other is to run a locally installed PSM from a hard-drive. To run the PSM directly from the utility CD, insert the utility CD into CD-Drive and click the Run from CD button in an auto-start window. If the auto-run window does not show up automatically, open My Computer and explore on the CD-Drive where the utility CD is inserted and execute WiJET.Video.exe. To run the locally installed PSM from a hard-drive, start PSM program located under the Programs Folder in the Windows Start menu, WiJET.Video Utility as shown in Figure 3.2. You can also double-click on the WiJET.Video shortcut on Windows desktop to start PSM. WiJET.Video Technical Manual Page 8 of 29 Figure 3.2 Location of installed WiJET.Video When the PSM starts, it displays the note below about configuring your wireless NIC to link with the WiJET.Video unit:

Figure 3.3 Radio Linking Message Once you have acknowledged the above message, the main PSM dialog displays as below, as well as start out a WiJET.Video tray icon. Figure 3.4 WiJET.Video PSM There are several action buttons in the PSM. The functions of these action buttons will be described in detail in the following sections. Establish a Session:

o Play Video o Launch PowerPoint Release the Session WiJET.Video Technical Manual Page 9 of 29 Exit. Clicking Exit will quit the PSM program. 3.5 Configuring the Wireless Adapter to Connect with WiJET.Video 3.5.1 Configure the Wireless Network Adapter Look at the banner page on the projector/monitor screen in your meeting room to determine the SSID and the channel that the WiJET.Video is currently set on. The channel number ranges from 1 11 for the US or 1 13 for Europe. WiJET.Video operates as an Access Point, or, AP. It therefore must be set an SSID. When the product starts up, its SSID will be displayed on the upper left corner of the monitor/projector. Once you have learned the SSID of the unit, you should use your wireless adapter cards facility to connect it to that SSID. Of course your wireless card should be set to work in the infrastructure mode. There are many ways the wireless adapter cards get configured. The following is an example sequence. Open the Wireless Configuration Utility program (which may be called a different name) provided by the manufacturer of the wireless network adapter and modify the settings as the following:

Change the network type to the Infrastructure mode. Change the SSID of the wireless network adapter to that of the unit that appears on the upper-left corner of the projector/monitor screen. Observe the indications on the wireless configuration program to assure that it is connected to the WiJET.Video unit. 3.5.2 Configure the Wireless Adapter for Windows XP To configure your Wireless Network Adapter for Windows XP, you must first know if your Wireless Adapter is natively supported under Windows XP. The easiest way to know this is to see if an icon is in your system tray as in Figure 3.9. Figure 3.9 Network Adapter with native support under Windows XP If your system tray looks like the figure shown in Figure 3.9, your wireless card is natively supported under Windows XP and you should read the rest of this section. It will instruct you on how to connect your wireless adapter to the unit under Windows XP. If you do not have the addition Wireless Network Connection icon in your system tray as shown in Figure 3.9, you should check if you have any Wireless configuration utility in your system tray instead, as in Figure 3.10. WiJET.Video Technical Manual Page 10 of 29 Figure 3.10 Network Adapter utility provided by 3rd party If your system tray looks like the figure shown in Figure 3.10, your wireless card is not natively supported by Windows XP and you should go to the section above labeled Manually Configuring the Wireless Adapter. To configure the natively supported network adapter, double-click the wireless network connection icon in the system tray. You should get a figure much like Figure 3.11. Click the Properties button. A new window much like Figure 3.12 should appear. Figure 3.11 Wireless Network Connection Properties Click on the Wireless Networks tab and you should see a figure like Figure 3.13.

WiJET.Video Technical Manual Page 12 of 29 Figure 3.15 Preferred networks changed to Ad Hoc networks only If there is more than one network, you must use the Move up and Move down buttons to move the WiJET.Video you wish to have connected to the top. When you are done, press the OK button. At that time, you should be able to connect to the unit and your system tray should display an image much like Figure 3.16. Figure 3.16 Connected to WiJET.Video 3.6 Start or Resume Your Presentation Session Once you have successfully configured the wireless card to connect to the WiJET.Video and when it is your turn to make a presentation, click Establish a Session and you should find yourself connected to the unit. There will be a confirmation window alerting you that your session is on, and your projector or monitor should now display your Desktop. Various abnormal conditions, such as RF interference or network time-out, however rare in occurrence, can cause the communication between the unit and the PSM to be interrupted. If an interruption of session is detected, the product will automatically try to WiJET.Video Technical Manual Page 13 of 29 reconnect and keep the user in session. In case of failing to keep the use in session, WiJET.Video will return to the banner page and be available for a new session. Certain abnormal conditions that cause interruption of the link may be localized on the current presenters computer and/or its wireless card. If the anomaly persists but can be localized on the current presenters computer system, another presenter can still make use of the projector/monitor by clicking the Establish a Session button on his/her PSM. 3.6.1 WiJET.Video is Occupied Message Another presenter may already have an active session with the same unit you are trying to connect. In this case, the following message box will be displayed for your information. 3.7 Play Video Click this button to play a motion video via the WiJET.Video. Another dialog will show up for choosing the video file to be played. WiJET.Video supports the playing of a single video file or all the contents on a drive, like a DVD. To preserve the communications capacity for better video transmission and playing, other screen contents will not be duplicated over the WiJET.Video. 3.8 Launch PowerPoint PowerPoint files with embedded motion video must be played with this function. Clink this button and a dialog will be shown for choosing a PowerPoint file to be rendered via the WiJET.Video. 3.9 Release Your Presentation Session If at any time you wish to release your computer from the unit, simply bring up the PSM and click on the Release a Session button. The wireless link to the unit stays alive after clicking the Release a Session button so a presenter can quickly get back to another turn of presentation. 3.10 Exit the Presentation Session Manager Either clicking the Exit button in the PSM, or right-click the WiJET.Video Tray Icon and then click Exit will terminate the PSM program. The Tray Icon will disappear from your Windows start menu. WiJET.Video Technical Manual Page 14 of 29 Chapter 4: WEB-SERVED ADMINISTRATION APPLICATION 4.1 Introduction to the Web-served Administration Application Along with the software-based PSM available on the install CD, the WiJET.Video also has a Web-served application that allows you to configure other aspects of the product. This includes change of the banner page, the wireless security and encryption settings of the WiJET.Video, and upgrade of its firmware. Warning: Do not power off or disconnect WiJET.Video unit while modifying its settings. Doing so may damage the equipment. The web-based utility will automatically reboot the unit as appropriate. 4.2 Accessing the Web-Served Administration Application To access the web-based administration utility, the user needs to install the WiJET.Video Administration Manager as described in Chapter 2 Installation for the WiJET.Video Administration Manager. To use its Administration Manager, the users must have an IEEE 802.11g wireless network adapter and the WiJET.Video Utility installed on their PCs. The users can start the Administration Manager by going through START, Programs, WiJET.Video Utility, and then Administration. Once Administration manager has started, the user will see a window as the figure 4.1.

WiJET.Video Technical Manual Page 20 of 29 Chapter 5: TROUBLESHOOTING 5.1 Unable to Connect or Establish a Session with Unit If you see the screen as in Figure 5.1 while trying to establish a session with WiJET.Video, the possible causes are listed below. Figure 5.1: Target Not Found 1) The SSID of the PC wireless adapter is not set up to be the same as the unit. 2) The computers Wi-Fi Adapter is not set to Infrastructure mode. 3) The computers Wi-Fi Adapter is not set to use the same encryption settings as WiJET.Video once the units default encryption settings were changed. 4) The unit is somehow not receiving the wireless signal, power-cycle the WiJET.Video. 5) Some DHCP-enabled wireless network connection client may take a while to obtain a valid OS-assigned IP address. You can use ipconfig command to see whether a valid IP address has been assigned or not to the corresponding network connection. 6) With certain brands of PCMCIA 802.11g Wi-Fi cards, it might take a bit longer to link up with the WiJET.Video than with other brands of PCMCIA cards. The reason for this is that the drivers and features set of each brand might cause the link up time between the WiJET.Video and the computer to take longer. Simply click Retry as you see on Figure 27 and let the Connect Status screen show up again. If the Target Not Found window appears again, there probably is no link established between the WiJET.Video and the computer. 5.2 The Presentation screen appears frozen during a presentation This indicates that WiJET.Video unit has detected a link-loss. WiJET.Video and PSM have an intelligent built-in mechanism to detect the link-loss and can automatically restore the connection by coordination. When a link-loss has been detected, The PSM displays a message box and trying to automatically restore the connection. If the auto-

reconnection attempt is successful, user does not need to do anything. In this case, the auto-reconnection is user transparent. However, if the cause to the link-loss is due to physical disconnection, for instance, the PCMCIA card was pulled out, user needs to restore the physical connection so that the auto-reconnection attempt can succeed. WiJET.Video Technical Manual Page 21 of 29 The presentation screen wont be updated once the link is lost, unless a reconnection is re-established. However, if link-loss stays for an extended period, the product will terminate the reconnection waiting state and display the banner page indicating that a fresh presentation session is ready for being established. The default duration for a link-loss is 8 seconds. WiJET.Video will retry 3 periods of this duration. If no re-connection is established before the reconnection time running out, the product returns itself to the banner page. 5.3 The WiJET.Video Session is Interrupted During a Presentation This signals that the unit has detected a link-loss for an extended period of time or severe communication error. Since the product is designed to support one presentation at a time, the product cleans up the communication error and returns itself to the initial state (where displaying the banner page is a part) of being available for connection in order to prevent the unit from being locked up with one possibly malfunctioning user computer. With the auto-reconnection feature, this rarely occurs. When this condition occurs, follow the steps below:

1) The current presenter should click Establish a Session to try to resume the presentation. If the presentation is successfully resumed, the abnormal condition is just temporary and no further action is required. 2) If the current presenter failed to resume presentation by clicking Establish a Session, another presenter should try to Establish a Session. If this new presenter can successfully start a presentation, the problem was localized on the previous presenters computer and/or its wireless card. Address that problem after the meeting. 3) If a second presenter also fails to Establish a Session to the unit, a persistent abnormal condition has to be identified. Follow other trouble-shooting tips in this chapter to identify the persistent abnormal condition. 5.4 Radio Interference You may be able to eliminate RF interference by trying the following:

Find the channel used by the source of the interference and coordinate your network and the interference source to be on channels that are at least 20MHz, but preferably 30MHz, apart. All neighboring networks should be 4 channels apart. Move the unit to a location where the interference is minimized; in general, increase the distance between the wireless computers and the device causing radio interference. Avoid using 2.4GHz cordless phone in the vicinity of the radio. Keep the computer and the WiJET.Video unit away from the microwave oven and large metal objects. Consult the dealer or an experienced radio technician for help. WiJET.Video Technical Manual Page 22 of 29 5.5 Technical Support Visit http://www.otcwireless.com/.
