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.

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.

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.

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!

Routing the CAT-5cable

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.

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 onthe floor or mounted anywhere near the computer, hub,
