Welcome
This document describes how to install and use your Expedience
outdoor subscriber unit (OSU) to obtain wireless high-speed Internet
access. You can connect your OSU to a computer or to a small office/
home office (SOHO) local area network (LAN) through a hub,
switch, or router.
BEFORE YOU BEGIN
• Make sure your computer is equipped with an Ethernet network
interface card (NIC).
• The Ethernet cable that is supplied with your OSU plugs into
any standard Ethernet NIC. The NIC is not provided with
the OSU, but you can purchase a NIC at most computer and
electronics stores.
• Make sure you have purchased an RJ-45 cable. The length of this
cable depends on where you plan to install the OSU on your
house.
• Make sure you have purchased grounding wire of sufficient
length to run between the OSU and a grounding pole. Also, you
need to purchase grounding wire to run between the NIM box
and the grounding rod.
• The grounding wire you purchase should be an 8 gauge, solid
aluminum wire.
• It is recommended that the grounding rod you use be 8 foot
copper. Note that every house has a grounding rod outside.
If desired, you can install a rod into the ground outside the
house.
• Find an appropriate location on the outside of the house to
mount OSU.
• To provide Internet service, your OSU communicates with a
device on your service provider’s communications tower.
Your service provider must provide you with information
about the nearest communications tower. For example, if the
tower nearest to your home is north of your home, you will
install the OSU on the north side of your house.
• Mount the OSU in a high location on your home, such as un-
der the eaves of your house.
• Find an appropriate location on the outside of your house to
mount the NIM box.

• Locate the components shipped with your OSU device:
•OSUdevice
• Network interface manager (NIM) box
•SoftwareCD-ROM
• Power cable and power supply box
• Power/Ethernet cable
•Lagbolt(6)
•Hexscrews(2)

Connecting your OSU to a computer
This section describes how to connect your OSU to a computer.
If you want to connect your OSU to a network device (such as a
router or switch), refer to the section “Connecting the OSU to a
network” on page 24, in this guide.
INSTALLATION OVERVIEW
The installation consists of the following major tasks, each of which
is explained in greater detail in the sections that follow:
1 After ensuring your Ethernet NIC is installed properly, make sure
your computer is set up to automatically obtain an IP address.
2 Attach the OSU mounting bracket to the outside of the house,
then snap the OSU into the bracket.
3 Mount the NIM box to the outside of the house.
4 Run the power cable, the Power/Ethernet cable, and RJ-45 cable
through a hole drilled through house’s wall.
5 Plug the cables into the NIM box.
6 Connect the grounding wires.
7 Back inside the house, plug in the power cord to standard
household power.
8 Scan for the strongest service provider signal.
9 Connect to the Internet.
1SETTING UP THE COMPUTER TO DYNAMICALLY
RECEIVE AN IP ADDRESS
You must set up your computer so it can dynamically receive an IP
address. Your service provider assigns your computer an IP address
so that the Internet information you request can reach your computer.
• If you are running Windows 95, Windows NT, Windows 98 or
Windows ME, go to “Windows 95, Windows NT, Windows 98,
Windows ME: Setting up the network connection” on page 7.
• If you are running Windows 2000, go to “Windows 2000: Setting
up the network connection” on page 7.
• If you don’t see your operating system listed here, check the sys-
tem’s help file. Most explain how to set up a system to dynami-
cally receive an IP address.

2INSTALLING THE OSU
To install the OSU:
1 Attach the mounting bracket to the outside of the house.
2 Set the OSU inside the mounting bracket.
3 Tighten the lower mounting bolt to hold the OSU in place.
The following sections describe these steps in greater detail.
Attach the mounting bracket to the outside of the
house
1 Make sure you install the OSU on the side of the house that has
the greatest exposure to the communications tower of your ser-
vice provider.
When you purchase your OSU, the service provider can provide
you with information about tower locations that can provide the
OSU with greatest signal exposure. This information will help
you understand the best side of the house on which to mount
the OSU.
2 Install the mounting bracket to the house. The bracket (like the
OSU) must be installed vertically.
• Drill the two top holes 1.25 inches apart. Drill the bottom
hole 7 inches below the top hole.
• If possible, drill one upper hole and its corresponding lower
hole into a stud.
• After the holes are drilled into the house, drive the screws
through the holes on the mounting bracket and into the
house.

bracket to the house.

Setting the OSU inside the mounting bracket
The OSU must be installed vertically. The OSU has a peg on top, and
a peg on bottom. The upper and lower pegs snap into the mounting
bracket’s peg holes.
After you search for the strongest signal from the service provider,
you insert a screw through the adjustment arch into the adjustment
screw opening on the OSU.
Tighten this screw fully only after you have performed the tasks in
step 8 “Finding the strongest service provider signal” on page 19.

You must install the OSU vertically. To install the OSU in the
mounting bracket:
1 Make sure the bottom of the OSU faces the earth. This is the side
of the OSU labelled with a sticker “MOUNT THIS SIDE
DOWN”.
2 On the bottom arm of the mounting bracket, snap the OSU’s peg
into the peg hole.
To accommodate the height of the peg, you may need to bend
the mounting bracket’s edge down slightly.
3 On the top arm of the mounting bracket, snap the OSU’s upper
peg into the adjustment arch.
To accommodate the height of the peg, you may need to lift the
mounting bracket’s edge up slightly.

Partially tightening adjustment screws to hold OSU
in place
To make sure the OSU doesn’t slip out of the mounting bracket,
partially tighten the screws in the adjustment arch.
Because you still need to pivot the OSU along the adjustment arch—
in order to find the strongest signal from the service provider—do
not fully tighten the screws yet.
You will fully tighten the screws after completely. When the screws
are fully tightened, the OSU will no longer move along he adjustment
arch.
Figure 8 illustrates how the screw, split lock, flat washer and double-
tab washer are put together.
1 Assemble the screw, split lock washer, flat washer and double-tab
washer as shown in Figure 8.
2 On the upper arm of the mounting bracket, insert the screw
through the adjustment arch on the mounting bracket.
3 Partially tighten the screw on the OSU in hold it in place.
4 Because you still need to ground the OSU, do NOT fully tighten
the bolt on the bottom of the OSU yet. You will tighten this bolt
in step 6.
3ATTACHING THE NIM BOX TO THE OUTSIDE OF
HOUSE
To attach the NIM to the outside of your house:
Figure 8: Mounting screw assembly

14
1 Make sure the bottom of the NIM is facing the ground. A rub-
ber grommet is installed on the bottom of the NIM.
2 The screws provided with the NIM are self-drilling.
• Drive the upper screw through the opening in the upper
bracket and into the side of the house.
• Drive the lower screw through the opening in the lower
bracket and into the side of the house.
