Confidential and Proprietary Version DRAFT 2004APR29 4 of 11 Novra A75 Receiver 2.0 INTRODUCTION 2.1 Principles of Operation Somewhere in the world is a location that transmits your signal, along with many others, to your location and others. Your A75 sifts through all the signals for your signal, a DVB data stream. The A75 then de-encapsulates the IP information from the DVB stream and forwards it onto its final destination via a 100 Base-T Ethernet link. The A75 also transmits status packets to your computer where the A75 Management Console is located. The A75 Management Console is used to configure addresses, specify tuning parameters and select DVB information streams (PIDS). Once configured, the A75 will retain its settings and continue to forward data transmitted to you by your service provider even after restarting the A75 or your computer. The A75 Receiver is meant to run in the background. In most cases, once the options have been set, you will have no need to change them.

CAUTION: There are grounding requirements and other safety considerations associated with your outdoor antenna. Be sure to follow all local electrical standards and codes when installing and using an antenna.

(Or the A75 can be connected to the computer via a Hub with regular Ethernet cables.) 4) On your computer, create a file folder called "A75." The file folder can be under "Program Files" or in any other location. Note: The system will create additional files containing various configuration aspects as they are created. The system will locate these additional files in the same directory as the A75 Management Console.exe program. 5) Copy the file A75 Management Console.exe from the CD ROM to the "A75" file folder. 6) Shortcuts can be created if desired through the normal Windows procedures. 7) Open (run) the A75 Management Console.exe and proceed to section 4.0.
Confidential and Proprietary Version DRAFT 2004APR29 7 of 11 Novra A75 Receiver 4.0 MANAGEMENT CONSOLE SYSTEM CONFIGURATIONS 4.1 Configuring the A75 Data Receiver The data receiver configuration is very straightforward and can be shown in four basic steps: 1. Open (run) the A75 Management Console application 2. Configure the receiver IP addresses. 3. Set the receive channel. 4. Set the PID. Each of these three basic steps is presented below. Step 2: In figure 2, the A75 receiver IP addresses are configured according to the LAN at the receive site. Figure 2: Receiver IP Addresses Step 3: In figure 3, the receiver is tuned to channel 14, to match the broadcast modulator.

Confidential and Proprietary Version DRAFT 2004APR29 10 of 11 Novra A75 Receiver APPENDIX Miscellaneous Terms and Definitions Crossover Cable A crossover cable is a cable that is used to connect two computers by reversing, or crossing over, the cable pin contacts. This eliminates the need to use a hub when connecting two computers. It is also referred to as a "Null Modem" cable. DVB Digital Video Broadcasting (DVB) is a set of standards that define digital broadcasting using satellite, cable, and terrestrial infrastructures. FEC Forward Error Correction. A system of error control for data transmission where the receiving device can detect and correct certain errors. IP Internet Protocol. The network communication protocol used on Ethernet networks and the Internet. IP Address The 32-bit computer address defined by the Internet Protocol. It is usually represented in dotted decimal notation. Example: 192.168.111.112 MAC Address The Media Access Control (MAC) address is the unique hardware address for any piece of electronic equipment attached to a network. The MAC Address for your Novra A75 Receiver is displayed on a sticker on the bottom of the receiver. Mbps Mega bits per second. (Million bits per second) MBps Mega Bytes per second. One "Byte" in computer terms is the same as 8 bits. It is often referred to as a word. 1 MBps = 8 Mbps = 1 million Bytes (Words) per second = 8 million bits per second. Packet A packet is the unit of data that is routed between an origin and a destination. When any file is sent from one place to another (the Internet as an example) it is divided into "chunks" of an efficient size for routing. Each of these packets is separately numbered and includes the Internet address of the destination. PID Packet Identification Code. This code is used by the receiver to sift through the different packets of the transport stream. The transport stream contains data representing many different signals. The A75 software running on your computer, uses the PID number to find only those packets of data that contain the information you have requested. RAM Random access memory. Used for short term storage of information requiring quick access on a computer. Information stored in RAM can be accessed by the computer much faster than information on the Hard Drive can be accessed. Subnet A portion of a network, which may be a physically independent network segment, and which shares a network address with other portions of the network.
