4. Using the Notebook PC
Modem and Network Connections (optional)
The built-in modem and network model will come with an RJ-45 port which can accept either an RJ-45
network cable or an RJ-11 telephone wire. RJ-11 telephone wires are the standard wires used to connect
telephones to telephone outlets found in the walls of residential homes and some commercial buildings
(most commercial buildings have telephone wiring designed for phone systems). RJ-45 network cables
are found connecting network computers to network hubs or switches usually found in businesses.
NOTE: The built-in modem and network can also be installed by a certified Notebook
PC technician if you choose to upgrade your non-modem/network model after pur-
chase. Modem and/or network can also be installed as a PC card (PCMCIA).
WARNING! Only use analog telephone outlets. The built-in modem does not support
the voltage used in digital phone systems. Do not connect the RJ-11 to digital phone
systems found in many commercial buildings or else damage will occur!
Modem Connection
The telephone wire used to connect the Notebook PC’s internal modem should have either two or four
wires (only two wires (line 1) is used by the modem) and should have an RJ-11 connector on both ends.
Connect one end to the modem/network port and the other end to an analog telephone wall socket (the
ones found in residential buildings). Once the driver is setup, the modem is ready to use.
NOTE: When you are connected to an online service, do not place the Notebook PC in
suspend (or sleep mode) or else you will disconnect the modem connection.
Modem Protocols
The Notebook PC with internal modem complies with JATE (Japan), FCC (US, Canada, Korea, Taiwan,
and others), and CTR21 (see Appendix for supported countries) for almost worldwide protocol support.
Network Connection
Connect a network cable, with RJ-45 connectors on each end, to the modem/network
port on the Notebook PC and the other end to a hub or switch. For 100BASE-TX
speeds, your network cable must be category 5 (not category 3) with twisted-pair
wiring. If you plan on running the interface at 100Mbps, it must be connected to a
100BASE-TX hub (not a 100BASE-T4 hub). For 10Base-T, use category 3, 4, or 5
twisted-pair wiring. Duplex transfers (up to 200Mbps) is supported on this Notebook
PC but requires connection to a switch with “duplex” enabled. The software default is to use the fastest
setting so no user-intervention is required.
Twisted-Pair Cable
The cable used to connect the Ethernet card to a host (generally a Hub) is called a straight-through
Twisted Pair Ethernet (TPE). The end connectors are called RJ-45 connectors, which are not compat-
ible with the standard RJ-11 telephone connectors. If connecting two computers together without a hub
in between, a crossover twisted-pair is required.
