1.0 GENERAL INFORMATION

1.1 Functional Overview

The WaveCom TR2126SE is an MDS/MMDS Transceiver for use in wireless systems. The TR2126SE

integrates an LNA, downconverter, upconverter, power amplifier, RF and IF diplexers to provide a one-box

solution for two-way wireless RF communications. The TR2126SE and antenna are situated outdoors and

connected to a cable modem indoors by standard RG-59 cable. A single RF connector on the weatherproofed

enclosure provides the interface to the transmit/receive antenna for rapid setup. The Transceiver is

configured to work with standard cable modem frequency plans and levels, permitting direct connection. The

Transceiver also includes an RF mute function to reduce power consumption and broadband noise emissions.

1.2 Module Features

• +27 dBm output for high reverse channel system gain

• Microprocessor controlled gain compensation over temperature

• Low Phase Noise

• Automatic transmit RF mute (transmits only when an IF signal is present)

• Fully weatherized unit, suitable for outdoor mounting

• Audible self install indicator (optional feature)

2.4 Connection to the Power Inserter and Cable Modem

Connect the TR2126SE F-Connector to the power inserter, located indoors with the cable modem. Connect

the power inserter to the Cable Modem. If the TR2126SE is equipped with the optional self install feature,

insure that the power inserter is connected to the Cable Modem, only after the antenna is aligned.

The power inserter has three connections:

DC POWER Connect to wall adapter with RG-59 cable with F connectors

TO MODEM Connect to cable modem (install modem only after the antenna is aligned)

TO TRANSCEIVER Connect to TR2126SE

WARNING!

If the power inserter is not connected correctly, the TR2126SE will not

operate, and there is the potential to damage the cable modem.

Ensure that all wires and cables are hooked up before plugging into the

AC adapter/power supply (i.e. hook up to the power supply last).

2.5 Waterproofing Connections

Many transceiver problems can be attributed to environmental conditions (including vibration), which can

loosen cables and permit moisture to penetrate the connectors. It is highly recommended to seal the

connectors using a technique similar to the one described below. This will provide moisture protection and

keep the connections tight. For your convenience, WaveCom has provided two 6 inch lengths of rubber self-

amalgamating sealing tape to use on the two connections of the TR2126SE. The diagrams below show the N

connector, but the F connector also should be sealed using the same technique.

STEP 1

Use one 6” section of rubber sealing tape. Starting at the TR2126SE end, stretch the tape and wrap it around

the connector as close as possible to the wall of the TR2126SE. Overlap the tape by approximately one-half

of it’s width so that it can form a seal with itself. Extend the wrapping to approximately one inch past the end

of the connector.

3.0 TUNING THE ANTENNA

Note: This section applies only to TR2126SE transceivers fitted with the optional self-install

feature.

3.1 Preparation for Tuning

Before tuning the antenna insure that the Cable Modem is not connected to the power inserter. The Cable

Modem signal will prevent the signal strength indicator from responding to very weak receive signals.

3.2 Signal Strength and Alignment

The TR2126SE is equipped with an audible alignment aid that simplifies the setup process. It permits the

antenna to be aligned to the hub site without the use of the cable modem or any test equipment.

The aid consists of a level detector for the full receive band, and a beeper sealed into the unit that sounds at a

rate that increases with increasing level. The beeper is activated only for about 3 to 10 minutes each time

power is applied to the TR2126SE.

To use the aid, first mount the TR2126SE and the antenna with the antenna mounts left loose to permit

alignment. Connect the antenna to the TR2126SE ANTENNA port, and apply DC power to the TR2126SE

through the MODEM port when you are ready to begin. The beeper will start sounding. Point the antenna in

the general direction of the hub site, then move the antenna to maximize the rate of the beeper. The highest

rate heard represents the highest receive signal level and the best alignment. Tighten the antenna mounts.

The beeper will automatically mute between 3 and 10 minutes after the unit was powered up, turning off faster

with higher received signal level.

The detector operates over a wide level range. Installations that are closer to the hub site and consequently

receive a larger signal will have a higher beep rate than an installation further out. In each case, finding the

alignment with the highest beep rate indicates the best alignment.

Note that the TR2126SE alignment aid does not discriminate between signals in the receive band. If signals

other than those from the hub are present, this could result in a misalignment. In this case, a conventional

alignment technique would need to be employed.

3.3 Resetting the Beeper

To reset the timer for alignment, simply unplug the power supply from its AC connection. Wait 5 seconds, then

plug the power supply back into its AC connection. The beeper will begin beeping as soon as power is

available.
