Preparing Installation

Before installing your Outdoor Wireless LAN system for your outdoor
application in a hard-to-reach location, we recommend that you configure
and test all the devices first.

For configuring the Outdoor Router/Bridge, you need follow the quick steps
below to power up your Router/Bridge:

Step 1:

antenna connector and then connect the antenna to the other end of the RF
cable as shown in Figure 1.3.

With the unit powered off, attach one end of the RF cable to the

information. After configuration is completed, this cable will be removed, and
then you should run an Ethernet cable from Data Input Port (on the front of
the Inline Power Injector) to the LAN connection (such as to a hub, bridge or
directly into a patch panel).

Plug the MIL-C-5015 style Ethernet connector into the Special

Step 4

Ethernet port on the back of the Router/Bridge.

Plug the RJ-45 Ethernet connector (the other end of the Special

Step 5

Ethernet cable) into the Power & Data Output Port on the front of the Inline
Power Injector.

When the Router/Bridge receives power over the Ethernet cable, the
Router/Bridge will start its boot sequence and the Active LED on the front of
the Inline Power Injector will light up.

You can configure the Router/Bridge using the HTML browser, such as
Internet Explorer or Netscape Navigator from a remote host or PC.
(Please consult the “Quick Setup” section).

Plug the female end of the power cord into the Inline Power Injector,

Step 2

and then plug the male end of the power cord into a power outlet or power
strip. The Power LED on the front of the Inline Power Injector will light up.

Run the cross over Ethernet cable (included in your package) from

Step 3

Data Input Port (on the front of the Inline Power Injector) to the Ethernet Port
on a PC.

NOTE: This connection is required for setting up initial configuration

Outdoor Installation

Outdoor Router/Bridge device can be mounted on the side of a
building or mounted to an antenna mast as shown in Figure 1.5 and
Figure 1.6.

A wall (side) mount
allows for mounting an
antenna (mast) on the
side of a building or on
the side of an elevator
penthouse. This will
provide a convenient
mounting location
when the roof
overhang is not
excessive and/or the
location is high
enough to provide a
clear line of sight.

In most situations
mounting an antenna
directly to the wall will
not allow you to
properly align the
antenna with the
corresponding antenna
at the opposite end of
your wireless link. As

poor alignment will
typically result in poor performance, we advise you to always mount
the Outdoor Router/Bridge and antenna to a mast.

Antenna Mast Requirements

To accommodate the outdoor antennas, the antenna mast must satisfy
the following requirements:

a. The construction of the mast must be of a sturdy, weatherproof and
no corrosive material like for example galvanized or stainless steel
construction pipe.

1 - 5

b. Typical diameter of the mast should be between 35 mm (1.4 in.) and
41 mm (1.625 in.). Subject to the type of antenna that you intend to
install other diameters may be possible as well.

c. The height of the antenna mast must be sufficient to allow the
antenna to be installed at least 1.5 m (5 ft.) above the peak of roof. If the
roof is metal, then the height of the antenna should be a minimum of 3
m (10 ft) above the roof.

d. The mast or wall-bracket must be free from any substance that may
prevent
a good electrical connection with the antenna; for example, paint.

Grounding

A safety grounding
system is necessary to
protect your outdoor
installation from
lightning strikes and
the build-up of static
electricity.
So direct grounding of
the antenna mast,
Outdoor Router/Bridge
and
Surge Arrester is very
important. The
Outdoor Router/Bridge
has built in Surge
Arrester. So Mounting
the Outdoor
Router/Bridge on the
antenna mast, you
have to connect the
Outdoor Router/Bridge
to the same grounding
system with the AC

wall outlet.

The grounding system must comply with the National Electrical Code
and safety standards that apply in your country. Always check with a

1 - 6

qualified electrician if you are in doubt as to whether your outdoor
installation is properly grounded.

Antenna Alignment

For optimal performance of your wireless link, make sure that the
antennas are properly aligned (facing one another “eye-to-eye”). To
align the antennas:

_ Use a pair of binoculars and/or a map of the area and compass to
point the antennas to one another.

_ Use the Utility- “Wireless Link Info” in the Web Configure as
described in the "Utility " section to analyze the radio link quality.
The “Wireless Link Info” will enable you to display the levels of signal
strength and link quality.
Looking at the Wireless Link Info screen, you can interactively
optimize antenna alignment if required, by making small modifications
in the antenna orientation.

_ Alternatively, consult a professional Antenna Installation Service to
optimize the antenna alignment.
Omni-directional antennas are characterized by a wide radiation
pattern. Therefore alignment of this type of antennas is less critical
than for directional antennas.

Chapter 2 Quick Setup

This chapter describes how to easy setup and configure the Outdoor
Wireless Router/Bridge System (RB). The RB can be configured into two
roles: Root Access Point (Root AP) and Remote Extension Bridge (Remote
RB) to accomplish the broadband wireless point-to-point and multipoint
systems (as shown in Figure 2-1.). Users can use a LAN-attached (wired or
wireless) computer to configure the RB through a web browser or a telnet
session on a LAN computer.

3. Connect a computer to the same network with this RB

4. Start your Microsoft Internet Explorer web browser program from a
LAN-attached computer. To access the web interface of the RB, you
have to disable Access the Internet using a proxy server function in
View / Internet Options / Connection as shown in Figure 2-2 or add
the IP address of the AP (default IP address is 192.168.2.1) to Bypass
proxy server for local addresses as shown in Figure 2-3.

5. Type the IP address and HTTP port of the RB (default IP address is

192.168.2.1) in the address field (http://192.168.2.1:2000/) and press
Enter. Make sure that the IP addresses of RB and your computer are in

the same subnet.

6. After the connection is established, you will see the User Identification
Window as shown in Figure 2-4 Enter the proper User Name and
Password to see the web user interface of the RB. The default user
name and password is root and root, respectively.

Figure 2-1

In this chapter, we only describe how to quickly configure the RB with a web
browser. For detailed descriptions of the many configuration parameters and
network configuration, refer to Chapter 3.

Configure Requirements

Before setup, we must install RB first

1. Connect power adaptor and power on the RB

2. Connect the Ethernet cable for connecting the RB to the network

Configure the RB

The RB can be configured into two operation roles:
Root Access Point ( Root AP ) and Remote Extension Bridge ( Remote RB ),
the Root AP can performed in four operation modes

1. Wireless Access bridge

2. Wireless Access router with PPPoE Ethernet connection

3. Wireless Access router with dynamic IP address Ethernet

4. Wireless Access router with static IP address Ethernet
The RB is shipped with default configuration is as a bridge between an

Ethernet and wireless network. Users simply need to attach the RB to your
wired LAN. If users would like to configure the RB, please refer to the
following procedures.

The web user interface can be grouped into Quick setup, Basic

Configuration, Advanced Configuration and Utility as shown in Figure
