Chapter 1: Introduction
The Telex Wireless CPE/Outdoor Bridge
Perfect for the home or small office connection to the network, the Telex Wireless CPE
(Customer Premise Equipment) extends wireless connectivity from an access point to any
Ethernet-ready network device, such as a switch, router, desktop or notebook PC. The Wireless
CPE simply and efficiently transmits data between 10Base-T and your wireless LAN or wireless
ISP access point.
The Telex Wireless CPE gives you the freedom to place any standard networked computer
anywhere within range of an access point. A built-in 18 dBi antenna and 50 mW radio means
that you can easily cover distances of up to 8 miles at 1 Mbps and up to 3 miles at 11 Mbps.
Based on signal strength, it dynamically shifts between 11, 5.5, 2 and 1 Mbps network speeds for
maximum reliability of connection. So you’ve got the flexibility and performance you need
from your wireless LAN or wireless ISP.
Wireless data or VoIP is transmitted and received from the CPE to the network access point (AP)
on the 2.4 GHz ISM band. The radio signal path must be line-of-sight (LOS) between the 2
antennas.

Chapter 2: Getting to Know the Wireless CPE
Inside the Wireless CPE
Before you can either test or install the Telex Wireless CPE, you must attach a length of outdoor-
rated (external) CAT-5 Ethernet cable to the unit. Remove the access panel from the rear panel
of the CPE using a 5/16” nut driver or wrench. Loosen the plastic nut on the outside of the
waterproof cable entry grommet, then insert the unterminated end of a length of exterior CAT-5
8-conductor Ethernet cable through this grommet.
Attach a standard RJ45 connector to the end of this cable using standard wiring for a straight
(non-crossover) connection. Plug this connector into the RJ45 socket on the PCB (printed circuit
board) that is attached to the access panel. Tighten down the cable strain relief clamp on the
cable. Do NOT unplug the small antenna cable from the radio card unless absolutely necessary.
WARNING: Before touching the PCB, make sure that you are grounded and have dissipated
any static charge to ground.

You will see a small 2-position slide switch near the RJ45 socket. If you are connecting the
wireless CPE directly to a computer network card or other Ethernet device, then slide this switch
toward the RJ45 socket. If you are connecting the wireless CPE to a hub or switch, then slide
this switch away from the RJ45 socket. Later, when you apply power to the unit, the second
green LED will indicate if this switch position was properly selected.
There are two small pushbutton switches on the PCB. These are only used if you wish to reset
the wireless CPE to factory default settings. (e.g. you forgot or lost the user name and/or
password)
Allow approximately 6 inches of CAT-5 cable between the grommet and the PCB, then tighten
the outside nut of the weatherproof grommet. Also ensure that the inside nut is secure. Make
sure that both the small antenna cable and the CAT-5 cable are secure, then re-attach the access
panel to the CPE rear panel before proceeding.
The Power-over-Ethernet (PoE) injector
The Telex Wireless CPE uses a PoE injector to supply DC power to the device. To test the
wireless CPE, install another RJ45 plug to the other end of your exterior CAT-5 cable and
connect this end to the PoE box in the socket marked ANTENNA. Also connect one end of the
supplied 7 foot CAT5 patch cable in the socket marked COMPUTER. The other end of this 7
foot cable will plug into the Ethernet port of your computer or into a hub or switch port. Plug the
supplied 12 volt 1 amp supply into a standard 110VAC outlet or power strip. Plug the other end
of this DC supply into the PoE box in the socket marked DC.
WARNING: Make sure that the antenna is pointed away from any humans or animals while
power is applied! A safe distance is approximately 10 inches or more.
The PoE injector box may be placed on the floor or mounted anywhere near the computer, hub,
switch or router.

The Rear Panel LED’s (v 1.2.5 firmware)
There are 4 LED’s visible from the rear side of the wireless CPE. These can be seen through the
small window in the access panel. When powered-up, the first green LED will be lit ONLY if the
PoE box is connected to an active Ethernet port. If it does not light, then check that all cables are
plugged into the PoE box and the power strip is turned on (if used). If power is supplied and the
cable is plugged into an active Ethernet card, hub, switch or router and the first green LED is not
lit, then move the switch on the PCB inside the CPE to the other position. If this LED is still not
lit, then check the wiring of the RJ45 plugs on the exterior CAT-5 cable. Also check to make
sure that the computer, hub, switch or router is turned on. This green LED will fast blink when
passing Ethernet traffic. The second green LED will light when a connection or association has
been established to a wireless access point and will blink when passing wireless traffic.
The first red LED (3rd LED in line) indicates an Ethernet collision. The second red LED (4th
LED in line) indicates a WLAN error. This LED will light if an access point goes down or is
unavailable after a connection has been made with the CPE. This LED will NOT light if the
SSID is left blank (to use any SSID) and no access points are available. In general, the GREEN
LED’s indicate normal operating conditions and the RED LED’s indicate errors.
The window that covers these LED’s should be securely attached to the access panel at all times.
This helps to keep dust and moisture out of the CPE.
WARNING: Unplug the power supply from the PoE box before installing or handling the
wireless CPE.
11
Chapter 3: Installing the Wireless CPE
Selecting a Mounting Location
It is very important to position the CPE to ensure the highest possible data transfer speed in all
kinds of weather and in all seasons. The wireless CPE operates on a radio frequency of 2.4 GHz
and must be line-of-sight (LOS) with the access point (AP) or other CPE if in Ad-Hoc mode.
Hills, buildings, trees and large vehicles must not block the signal path. Trees are especially
troublesome as they may allow the signal to pass easily in winter when leaves are off, but may
block the signal in the other seasons. Check the FAQ’s under “Pre-Installation and Site
Preparation” or “Radio Propagation” or “Troubleshooting” on the Telex Wireless web pages for
helpful hints. (http://www.telex.com/Wireless/faq.nsf/c)
Determine the exact location of the nearest Access Points (AP’s) in your system. Choose a
location on the roof, mast, wall or fascia for your wireless CPE so that the CPE has a clear shot
to your AP. The closest AP may not necessarily have the best path if it is blocked by hills,
buildings or trees.
Ensure that the chosen signal path has sufficient Fresnel zone clearance with respect to the
ground or other obstacles near the path. Check the Telex FAQ’s under “Radio Propagation” for
more information on Fresnel zone clearance.
Ensure that your mounting location is less than 100 meters from the computer, hub, switch or
router location. (Maximum length of CAT-5 cable is 100 meters) Determine the building entry
point ahead of time to prevent problems later.
Limit the exposure of the CPE to wind if possible. Mounting the CPE on the fascia (under the
eaves) is best if the signal path is not blocked in this location.
Attaching the Mounting Bracket and Aiming
First, determine the polarization of the wireless CPE. If the Access Point uses vertical
polarization (V-pol), then the CPE must be installed vertically polarized. If the AP is H-pol, then
the CPE must be installed horizontally polarized. The arrow on the CPE label points vertically
when it is V-pol, and horizontally when H-pol. The arrow direction also corresponds with the
long dimension of the CPE radome.
12
If attaching the wireless CPE to a mast, pipe or DSS dish-mount, then attach the angle bracket to
the mast as shown, using the U-bolts, nuts, washers and serrated clamps from the parts bag. If
possible, sight along the top of the angle bracket to aim the wireless CPE in the correct direction.
If you are using a vertical mast and require upward or downward beam tilt to the AP, then use
the optional holes in the angle bracket to obtain a 10 degree tilt, either up or down. If you
require more than 10 degrees, then use a standard DSS dish-mount instead. After aiming the
bracket, attach the CPE unit to the angle bracket using the remaining washers and nuts. Tighten
securely after checking the signal strength.
If attaching the wireless CPE to the fascia (under eaves), then secure the angle bracket to the
fascia with a single wood screw, attach the CPE to the bracket, aim for maximum signal and
finally secure the bracket with the 3 remaining wood screws. Make sure that the fascia is strong
enough to support the weight and wind load of the CPE!
13
Routing the CAT-5 cable
When you have completed aiming and securing the CPE to the mount, attach and secure the
CAT-5 cable to the mounting pipe or other support using tie wraps or black electrical tape.
Secure the CAT-5 cable to the outside wall of the building using cable clamps and wood screws
or other suitable hardware. It is advisable to place a CAT-5 Surge Arrestor in series with the
cable before it enters the building. Also, create a “drip loop” before the cable enters through the
wall of the building. This prevents water from following the cable into the building.
Pull any excess cable into the building, then weather-seal the hole around the CAT-5 cable with
quality exterior grade sealant. Route the cable to the PoE location inside the building.
Connecting the Wireless CPE
Install an RJ45 plug to the end of your exterior CAT-5 cable and connect this end to the PoE box
in the socket marked ANTENNA. Also connect one end of the supplied 7 foot CAT-5 patch
cable in the socket marked COMPUTER. The other end of this 7 foot cable will plug into the
Ethernet port of your computer or into a hub or switch port. Plug the supplied 12 volt 1 amp
supply into a standard 110VAC outlet or power strip. Plug the other end of this DC supply into
the PoE box in the socket marked DC.
14
WARNING: Make sure that the front of the antenna is pointed away from any humans or
animals while power is applied! A safe distance is approximately 10 inches or more. The rear
side of the CPE is always safe.
The PoE injector box may be placed on the floor or mounted anywhere near the computer, hub,
switch or router.
There are 4 LED’s visible from the rear side of the wireless CPE. These can be seen through the
small window in the access panel. When powered-up, the first green LED will be lit ONLY if the
PoE box is connected to an active Ethernet port. If it does not light, then check that all cables are
plugged into the PoE box and the power strip is turned on (if used). If power is supplied and the
cable is plugged into an active Ethernet card, hub, switch or router and the first green LED is not
lit, then move the switch on the PCB inside the CPE to the other position. If this LED is still not
lit, then check the wiring of the RJ45 plugs on the exterior CAT-5 cable. Also check to make
sure that the computer, hub, switch or router is turned on. This green LED will fast blink when
passing Ethernet traffic. The second green LED will light when a connection or association has
been established to a wireless access point and will blink when passing wireless traffic.
The first red LED (3rd LED in line) indicates an Ethernet collision. The second red LED (4th
LED in line) indicates a WLAN error. This LED will light if an access point goes down or is
unavailable after a connection has been made with the CPE. This LED will NOT light if the
SSID is left blank (to use any SSID) and no access points are available. In general, the GREEN
LED’s indicate normal operating conditions and the RED LED’s indicate errors.

Chapter 4: Configuring the Wireless CPE
Overview
The Telex wireless CPE is shipped with default (factory-set) values for certain network settings.
You will need to change these settings at the client location to match those provided by your ISP
or IS Department.
To do this requires 3 main steps:
1. Change your computer network settings to match the default network settings in the CPE so
your computer can communicate with the CPE.
2. Using a standard web browser (Internet Explorer 5.5 or later, Netscape 7.0 or later), change
the CPE wireless network settings from the default values to the values provided by your ISP
or IS Dept. so that your CPE can communicate with the Access Point or another CPE.
3. If necessary, change the network settings on the CPE and computer to match other devices on
a wired network connected to the computer.
If you do not know how to enable and change network setting on your PC, contact your
network service provider (ISP or IS Dept.) support desk or a qualified PC technician for
assistance.
If your network service provider has not already provided you with specific network settings to
use, contact them now and ask for the following:
1. The IP Address assigned to your CPE:
2. The corresponding Subnet Mask:
3. The corresponding Default Gateway:
4. The corresponding SSID and radio channel:
If your network uses DHCP to assign IP addresses automatically, you may not need the IP
address, Subnet Mask or Default Gateway.
16
Step 1: Change your computer network settings
a. Enable TCP/IP networking on your PC if you have not already done so, then right-click (use
the right mouse button) on the Network (My Network Places) icon on your computer’s
desktop and select Properties from the pop-up menu.
b. Right-click on Local Area Connections and select Properties from the pop-up menu.

When all changes have been made and saved at the client CPE location, close the browser.
Subsequent changes may now be made from either the client location or anywhere on the
network as long as you are in the same subnet.
IMPORTANT: If you disassociate the CPE from the AP, either by changing a setting or by
resetting the CPE, you must reassociate the CPE from the client location.
24
Step 3: Reset Your Computer Network Settings
The last step in the CPE configuration is to reset your computer network settings so they match
the settings used by your CPE and your ISP’s or LAN’s access point. This step may be skipped
if no changes were made to the CPE IP address during Step 2.
a. Right-click on the Network icon (My Network Places) on your computer’s desktop and
select Properties from the pop-up menu.
b. Right-click on “Local Area Connection” and select Properties from the pop-up menu.
c. Select the installed TCP/IP protocol, then click the Properties button.
d. If using static IP addresses: Enter an IP Address for your computer that is different than
the CPE’s IP address. Usually, you can use an IP number that is one higher than the CPE
IP address. For example, if the CPE’s IP address is 192.168.1.99 then assign
192.168.1.100 to the computer. If you have many computers and CPE’s in your network,
then make sure that each uses a different IP address within the same subnet.
e. If using static IP addresses: Change your computer’s Subnet Mask and Default
Gateway settings to match the values you received from your ISP or IS Dept.
f. If you selected “Obtain an IP address automatically” in your computer, then the CPE
should transparently pass internet traffic to your computer. You will not be able to
change the CPE settings until you reset the computer to a static IP. Set the DNS Server
information if necessary.
g. Click on OK in each window to accept the changes.
h. Restart your computer if prompted.
i. If using a static IP on the CPE, open your web browser to the CPE’s IP address to ensure
that the computer can still talk to it.
25
Chapter 5: Managing the Wireless CPE
The initial association of the CPE with an access point must be performed at the client location.
However, once connected to the network, the CPE’s settings may be monitored and changed
from any computer on the same subnet.
From this remote computer, open the web browser and enter the CPE’s IP address as the URL.
You must know the User Name and Password for this CPE in order to log in and change the
settings.
Once logged-in, you may change anything except those items that affect the association of the
CPE with the rest of the network. If the association is lost, then you may only communicate with
the CPE from the local client computer.
These items may be easily changed:
Wireless Configuration:
Transmission Rate (to a lower value)
Access Point Density
Fragmentation Threshold
RTS Threshold if the packet size is larger than this value, it will initiate the RTS/CTS function
Bandwidth Management:
Upstream Limit
Downstream Limit
Events Logging:
Device Name
Syslog Server IP Address
Syslog Mark Interval
Changes to all other items must be evaluated with respect to their effect upon device association.
After you have changed the item setting, press Save then Reboot.
