Getting Started
It is recommended that you setup the EZ-Bridge™system in a
single room to get acquainted with the operation of the units before in-
stalling outdoors. Connect 1 EZ-Bridge™ to your router, switch or com-
puter and just power up the other EZ-Bridge™. Make sure the anten-
nas are pointing away from each other for best results. After powering
up each unit, you should be able to communicate with each unit by typ-
ing it’s IP address into a standard browser.
DANGER! Avoid Powerlines!
You Can Be Killed!
When following the instructions in this guide to install the EZ-Bridge™,
take extreme care to avoid contact with overhead power lines, lights
and power circuits. Contact with power lines, lights or power circuits
may be fatal. We recommend to install EZ-Bridge™ no closer than 20
feet to any power lines.
Safety: For your own protection, follow these safety rules.
▫Perform as many functions as possible on the ground
▫Do not attempt to install the antenna on a rainy, windy or
snowy day or if there is ice or snow accumulation at the install
site or if the site is wet.
▫Make sure there are no people, pets, etc. below when you are
working on a roof or ladder.
▫Watch out for any power lines which may be overhead, under-
ground or behind walls., keeping safely clear of them with the
antenna, ladders or any tools.
▫See appendix for FCC RF exposure guidelines
Recommended Tools: Pliers, Adjustable Wrench, Screws for
mounting Wall Mount Bracket, Drill or Screwdriver for installing
wall mount bracket, sealant for sealing any holes. NOTE: You
should be familiar with using tools such as these before attempting in-
stallation of EZ-Bridge™. You should also be comfortable with working
on a ladder.
GROUNDING: Local building and electrical codes require that
the antenna be properly grounded. Improper installation may
seriously damage the equipment or building, as well as cause in-
jury or death to you. Run a ground wire 10AWG or bigger from
back of antenna to a good earth ground (Cold water pipe or metal
stake in ground).

Qwik Install
STEP 1: Decide if install will be
VERTICAL polarity or HORIZON-
TAL polarity. We recommend hori-
zontal polarity because there is
usually less interference. Both
units MUST be installed using
same polarity.
STEP 2: Decide if UPTILT or
DOWNTILT is going to be re-
quired for the particular installa-
tion. Bracket will be attached to
back of antenna to provide uptilt
or downtilt by rotating the
bracket install orientation 180°.
STEP 3: Choose a mounting location with good line of sight to the re-
mote location. The antenna can be mounted to an existing pole up to 2”
diameter or by using the provided wall mount bracket. If only short dis-
tances are needed, the antennas can be mounted inside the building.
Install the antennas.
TECH TIP: Microwaves travel in straight lines and they lose
strength quickly when going thru buildings and trees. If there are
objects in the microwave path, then useable distance will be reduced. If
the target unit is less than 1 mile away then you won’t have to worry too
much about a couple obstructions but if over 1 mile and there are some
obstructions in the microwave path, then the performance will be re-
duced.
STEP 4: Install the CAT5 outdoor cable by
inserting the RJ45 connector thru the
feedthru and into the connector on the back
of the antenna. Screw the feedthru into the an-
tenna connector and tighten against the gasket.
While pushing the cable towards the connector,
tighten down on the feedthru cable clamp.
STEP 5: Route the CAT5 cable into the building. Always create a drip
loop near the antenna so the cable is not pulling on the antenna and
any water running down the cable isn’t going directly into the unit. Do
this by creating slack in the cable and tie wrapping the cable to the pole
or mount. Always seal any holes in walls or roofs properly to prevent

4
water ingress. The CAT5 cable can be extended indoors using a stan-
dard RJ45 coupler. The Ethernet spec allows for a maximum cable
length of 100 meters or about 328 feet.
STEP 6: Aim the antennas and tighten the brackets securely.
TECH TIP: Because of the specially designed wide beamwidth an-
tenna, pointing is not critical and simply pointing in the general di-
rection of the receiving antenna will yield great results.
STEP 7: Install the RJ45 connector
on the POE Inserter to the router,
switch or computer. Attach the CAT5
cable from the antenna to the RJ45
output port of the POE Inserter. Insert
poer supply DC plug to the POE In-
serter DC Jack. Plug in the power
supply to an surge protected AC
power source to power up the EZ-Bridge™.
Software Settings
We strongly recommend that you create a work-
ing plug and play link before making ANY
changes to the software settings
1. There is an HTML management system built into every EZ-Bridge™
unit which is accessed thru a standard browser. The unit can communi-
cate thru the CAT5 ethernet cable connection or thru the wireless con-
nection, so you can manage both sides of a link from a single location.
2. IP ADDRESS: Default IP addresses for the EZ-Bridge™ are
192.168.1.139 and 192.168.1.239. To access the EZ-Bridge™ your
computer IP address must be on the same subnet ie;
192.168.1.xxx.
TECH TIP: Download the EZ-Bridge™ Discovery Tool from http://
www.e-zy.net/outdoor/EZ-Bridge. This tool will assist you in finding the
EZ-Bridge™ on the network and allow you to change the EZ-Bridge IP
address or set it as a DHCP client. Just select the unit, click on IP DE-
TAILS, make selections and enter default user name and password to
save changes to the device.

3. SECURITY: Security is pre-configured with system passwords,
WPA2 encryption and Mac Address verification pre-set. This is so that
you can setup a plug and play link and have confidence that the link is
secure and that your data and network are safe. Once you feel comfort-
able with the system and its operation, we would recommend the fol-
lowing security changes :
a. PASSWORD: Change the user name and password on
each side of the link by going to ADMIN | Web Access and re-
setting the first user name and password. The default is user
name = EZTEAM and password = link4me
b. ENCRYPTION: Change the WPA2 encryption key by going
to SECURITY SETTINGS .
TECH TIP: When setting encryption you must setup both sides of the
link to have identical encryption keys. You can setup the remote unit
first and then the local unit last in order to be able to configure both
units from one location across the wireless link. HEX Encryption keys
can use the letters A to F, a to f and numbers 0 to 9. Passphrase keys
can use any ASCII characters. The more random the key, the more se-
cure the code.
4. CHANNELS: The default channel is set to channel 11. The only rea-
son you might want to change the channel is if you experience interfer-
ence from local wireless systems which are operating on the same
channel. To change the channel go to WIRELESS and change the
channel. Both sides of the link must be on the same channel and if set-
ting both units from one location, always set the remote unit first and
the local unit last.
5. TRANSMIT POWER (Tx Power): Normally there wouldn’t be any
reason to change the power setting. The factory default setting is
250mW which should be good for most applications. If you have a very
short link you will actually get better performance if you turn down the
Tx Power to ~100mW. This is because at close range there is too much
power and it has a tendency to overload the input stage of the units
and performance degrades.
TECH TIP: You may want to play around with different settings to see
what works best for your particular link. The measurement you would
use to compare settings would be to measure the actual thruput by tim-
ing the transfer of data across the link. One program that we have
found useful for determining thruput is DISKBENCH. (http://
nodesoft.com/DiskBench/).

6
6. SITE SURVEY: The site survey is a very useful tool to determine
what wireless devices are within range of your EZ-Bridge™ and could
be a source of interference that could cause degraded performance. Go
to WIRELESS and then click on SITE SURVEY then REFRESH. The
list will show all wireless devices including channel #, MAC Address
and relative signal strength of all the devices within the range of the EZ-
Bridge™ .
NOTE: Because SSID broadcast is disabled for security reasons, the
EZ-Bridge™ won’t show up in any site survey.
7. FACTORY DEFAULTS: If at any time the system stops working be-
cause of changes made to the settings, you can get back to the original
settings by resetting to factory defaults. Go to ADMIN | Reset Settings
to Defaults. You will need to reset both sides of the link in this way. Al-
ways reset the remote unit first and the local unit second. Any custom-
ized settings will be lost once this process is initiated.
8. UPGRADE FIRMWARE: Go to www.e-zy.net/outdoor/EZ-Bridge for
the latest firmware updates for EZ-Bridge™. Download the latest firm-
ware to your PC. Select UPGRADE from the menu and then browse for
the new file.
Advanced Features
The EZ-Bridge has many advanced features if more functionality is de-
sired than a simple point to point bridge application. To access the ad-
vanced features, click on Advanced Web at the top of the menu tree.
This will activate the advanced menu options.
In addition to point to point secure bridging the EZ-Bridge can also be
configured as an advanced access point router or an access point cli-
ent. Multiple units can also be configured as a mini mesh network using
WDS features available in the software.

Additional Information you may find useful
1. DHCP – DHCP is used to automatically assign IP addresses to com-
puters on the network. The DHCP server that is responsible for assign-
ing the IP addresses is usually the Router that connects your network to
the internet but it could be your computer if you are using Microsoft
Internet Sharing. Because of the seamless and transparent nature of
the EZ-Bridge™ connection, DHCP requests and responses will be
passed across the wireless link. We normally recommend that only 1
DHCP server exists on a given network to avoid IP confusion. IP confu-
sion would occur if two machines on the same network were given the
same IP address. The machines would report an IP conflict error if this
were the case. Keep in mind that with the EZ-Bridge™ link the two con-
nected networks will appear as one network because they are being
bridged seamlessly thru the wireless connection. If desired, the EZ-
Bridge™ can also be configured as a DHCP server on the NETWORK
page.
2.RAIN, SNOW, ICE – The 2.4GHz frequency being used by the EZ-
Bridge™ will not be affected by heavy rain or falling snow. You should
not see any performance degradation due to inclement weather. If snow
or ice collects on the front of the antenna, you may see some reduced
performance assuming you are shooting a long distance ( >3miles) and
the ice or snow buildup is greater than 1” thick on the surface of the
antenna. For this reason, we suggest mounting under an eave of a
house if feasible for your particular situation.
3.SUN AND HEAT– The EZ-Bridge™ is constructed of all UV pro-
tected materials so it will survive for many years in the most extreme of
solar environments (ie; an Arizona rooftop during the summer). The unit
has been tested and qualified for constant operation at over 122 deg F
ambient temperature. Even though the EZ-Bridge™ is designed for long
term survivability in extreme environments, we would still recommend
that the unit be mounted in a more protected location, like under a roof
eve, if possible. Of course if line of sight is better with the antenna
mounted in a non-protected environment then we would recommend
the better line of sight mounting location.
4.LIGHTNING – Lightning is the single worst enemy of outdoor elec-
tronics equipment. No electronics will survive a direct strike but there
are close proximity strikes that can cause huge electrical fields to be
generated which can damage electronic equipment. We have taken
special care in the design of the EZ-Bridge™ unit to ensure proper

9
grounding of the electronics inside the enclosure to prevent damage
from electrical storms. We use only the more expensive shielded
CAT5e cable to prevent electrical surges being generated within the
cable. Make sure that the POE Power Supply is plugged into a surge
protected outlet such as a surge protected power strip or UPS inside
the house.
GROUNDING: Local building and electrical codes require that the
antenna be properly grounded. Improper installation may seri-
ously damage the equipment or building, as well as cause injury
or death to you. In order to comply with codes, the mounting bracket
or pole needs to be grounded. These can be grounded by attaching a
wire to the metal and running the wire to a good earth ground (cold wa-
ter pipe, copper stake driven in the ground). If there are metal rain gut-
ters on the house, the wire can be run from the wall mount bracket to
the metal gutter and then another wire can be run from one of the
downspouts to an earth ground. Because of the random nature of light-
ning, we cannot warrant the EZ-Bridge™ against damage from light-
ning.
5.INTERNET ACCESS SHARING – The EZ-Bridge™ is the perfect
equipment to share your internet access with a friend or family member
up to 4 miles away. Using the EZ-Bridge™ provides a seamless con-
nection between networks and you can share the internet access avail-
able on the main network with the remote network. Please take note
that certain internet service providers may not approve of this and in
some cases, they may consider this to be illegal. It’s best before shar-
ing your internet connection that you check with your internet service
provider to make sure you aren’t in violation of your service contract.
6.PAINTING – The EZ-Bridge™ unit can be painted to match a particu-
lar house color. Only non metallic enamel or latex paints should be
used. If a paint with metal content is used, it will block the microwaves
and cause reduced performance.
7.COMMON MICROWAVE BARRIERS – Tinted windows are made by
applying a metallized film to the window. If a window has tinting, it will
usually block the microwaves and cause reduced performance of the
EZ-Bridge™ . Concrete walls are also a significant barrier to microwave
signals. Aluminum siding on houses is also a barrier to microwave sig-
nals. Wood frame houses covered with brick or stucco are pretty trans-
parent to microwave signals and they will reduce the signal strength but
the signal will still pass thru the structure. We are bringing this up to you
so you can better understand possible causes of performance issues
8.VOICE OVER IP (VOIP) – The EZ-Bridge™ supports all VOIP stan-

10
dards making it possible to use VOIP phones across any EZ-Bridge™
link.
9.TYPICAL APPLICATIONS:
a. Internet access sharing – share internet access with a friend or
family member
b. Link your Home Office to your Main Office - you can access
shared files and folders as well as print to the main office printers
and use other shared network devices remotely
c. Link networks in multiple buildings together – A company with
multiple buildings will find the EZ-Bridge™ an inexpensive way to
link their buildings together. Up to 4 buildings can be linked seam-
lessly using EZ-Bridge™ wireless bridges.
d. Add a high speed link between your home network and a PC in
your remote studio or office which is located in an outbuilding on
your property.
e. Create an online gaming link with a friend up to 4 miles away.
Reduce or eliminate extra fees you might be paying for online
access for gaming purposes. And have more bandwidth for the
increased complexity of future games including Voice and Video.
f. Create a secure link for remote video and network based security
cameras. The EZ-Bridge™ works with all network based security
cameras.
g. Create a streaming video conference link between buildings. Be-
cause of the high 15Mb/sec bandwidth available with the EZ-
Bridge™ , it easily supports streaming video technologies used
for remote conferencing, like church meetings, business meet-
ings, etc.
