A LocalTalk adapter with DIN-8 connectors doesn't require an external terminator. (For more information on terminators, see the instructions that came with the Apple LocalTalk RJ-11 Connector Kit. ) See "Configuring Your Network Connection" on page 50 for information on configuring your LocalTalk connection. Using Your PowerBook and Connecting to a Network 49 Connecting to a 10Base-T Ethernet Network The built-in Ethernet capabilities of your Macintosh PowerBook allow you to connect to a standard (10 Mbit) Ethernet network. If a network administrator is responsible for network maintenance and upkeep at your location, ask for help connecting your computer to the network. To connect your Macintosh PowerBook to an Ethernet network, use the Ethernet cable that came with your computer. (The connector on the cable looks like a standard telephone connector, but it is wider. ) To connect your PowerBook to an Ethernet network: 1 Open the cover on the computer's back panel to access your Ethernet connector (labeled with a G icon). - ¯ V ´ G g Æ TM G Ethernet port 2 3 Locate a modular Ethernet cable and connect one end of the cable to the network. Connect the free end of the Ethernet cable to the Ethernet port. - ¯ V ´ G g Æ TM 4 Set up your PowerBook software to use Ethernet communication. Configuring Your Network Connection After you physically connect your computer to a network, you need to configure the software for your network connection using AppleTalk and/or TCP/IP. You can find more information in the online help, available in the Help menu. 50 Chapter 2 Using Your PowerBook's Optional Internal Modem Some models of the Macintosh PowerBook come with an internal modem card installed in the communications slot inside your computer. To see if a modem is installed, open the modem panel on the left side of the computer. If you see a connector for a phone line, then the modem is installed. Modem panel Phone line connector Setting Up Your Modem's Connections To use the internal modem, you need the following: m the single-line telephone cord supplied with your PowerBook, which has a standard RJ-11 phone connector at each end m an analog telephone line (the type found in most homes) with a modular jack You can find more information on setting up your modem communication software to work with your PowerBook internal modem in the online help, available in the Help menu. Connecting the Telephone Line to the Modem Follow these steps to connect the telephone line to the modem. 1 2 Open the cover on the left side of the computer to expose the modem telephone line connector. Locate the telephone cord that came with your PowerBook. Use the telephone cord that came with your computer or an equivalent single-line telephone cord. Other types of telephone cords may not work correctly with the modem. Important Using Your PowerBook and Connecting to a Network 51 3 Plug one end of the telephone cord into the internal modem port on your PowerBook. 4 Plug the other end of the telephone cord into your telephone wall socket. Warning The telephone line must be an analog line--the type used in residences. Do not connect a digital telephone line to the modem, because the wrong type of line could damage the modem. Once the telephone line is connected, you are ready to begin using the modem. When you have established a modem connection with another computer or an online service, do not put the computer to sleep. Doing so will disconnect the modem. Important 52 Chapter 2 What Modems Do A modem allows your computer to communicate over telephone lines by converting information from the digital format used by the computer to the analog format used by most telephone systems. It dials the telephone number, establishes a connection with another modem, and controls the flow of data so that communication takes place with optimal speed and accuracy. The actual speed of data transmission can vary with line conditions. Because Federal Communications Commission (FCC) rules restrict the power output of modems used by service providers, transmission speeds are limited to 53 Kbps (53, 000 bits per second) in the United States. You can obtain speeds of 53 Kbps on downloads from an Internet service provider (ISP) that uses K56flex modems. Important To exchange data over a telephone line, your modem and the remote modem must establish a connection and agree on how data will be transmitted in these ways: m Connection speed: Initially, your modem tries to connect at its fastest speed. [. . . ] To avoid problems, place the Macintosh PowerBook close to the entrance of the machine and remove it as soon as possible. At most airports you can also have the computer hand-inspected by security personnel. Security officials may require you to turn the Macintosh PowerBook on. Make sure you have a charged battery on hand. [. . . ]
