CHAPTER 1 Basic Network Configuration Basic Network Configuration This section covers basic network configuration set-up and testing. Also covered are basic concepts and operations, including the difference between LAN and WAN networks and how IP Addressing is used. In a networked environment, such as a company, typically there are many computers connected together using a router or a switch.

Basic Network Configuration “node”), has its own processing unit and executes its own programs; however, it can also access data and devices anywhere on the LAN. This means many users can access and share the same information and devices. A good example of a LAN device is a network printer.
A wide area network (WAN) connects two or more LANs and can span a relatively large geographical area. For example, Telex Headquarters in Burnsville, MN is connected to several branch offices in Nebraska and Arkansas over a WAN. The largest WAN in existence is the Internet.
For example, port 80 is used for HTTP traffic. When you type an address into the address bar of a web browser, your computer goes to find an IP Address for the url you are requesting (http://www.telex.com). To obtain this address, the computer contacts a DNS server (Domain Name Server). Once the IP Address is found, it tries to connect to the http port of the network device (port 80).

Basic Network Configuration Packet Translation TABLE 2. Packet before Translation Source Port IP Address Number 10.2.100.1 1031 Internet From 192.156.136.22 Internet Amazingly, all the address translation that occurs takes place automatically in order to make web browsing and other functions easier. This is also a way for large web hosting services to speed up the network by having different devices perform different functions.

Basic Network Configuration IP ADDRESSES If you do not know your IP Address, you can open a DOS screen in a Windows up the ipconfig screen. To find your IP Address using ipconfig, do the following: From the Start Menu, open a Command Prompt screen. At the prompt, type ipconfig, then press Enter.

Basic Network Configuration Ping a Computer Pinging a computer on the network makes sure it is able to be “seen” and receive messages on the network. NOTE: You can also ping your RVON-8 card to verify that it is responding over the network by putting the cards IP Address in place of the computer IP Address.
Basic Network Configuration NOTE: If the computer you are pinging is not responding to the ping, you will receive a time-out message in the command prompt screen. POSSIBLE PITFALL WITH ROUTERS, GATEWAYS, AND SWITCHES Anytime computers communicate through routers, gateways, and switches, they may be allowed or denied the connection.
Network Terminology Figure X is an example of a router configuration screen. Not all routers are configured the same way and may not look exactly like this screen. NOTE: Linksys™ supports up to 253 nodes on a router. This is why it is called a Router/Switch because there are WAN functions like a router as well as having a 4-port LAN switch.

A DNS Server is an Internet service that translates domain names (for example, in the URL http://www.telex.com, the domain name is the telex.com) into IP Addresses. The Internet is based on IP Addresses which are numeric and since domain names are alphabetic, they are easier to remember.
Page 15
Network Terminology The four numbers in and IP Address are used in different was to identify a particular network and host on that network. There are three classes of Internet Addresses. CLASS A - supports 16 million hosts on each of 127 networks. CLASS B - supports 65,000 hosts on each of 16,000 networks.

RVON Serial and Telnet Commands RVON card programming can be done via direct serial or telnet connection. There are several physical connections to an RVON board: • Direct serial through custom debug cable (J20 6-pin bottom front) The customer debug cable always functions as the general-purpose debug tool. Backcard DB-9 J2 •...
