Basic Installation 2. BASIC INSTALLATION 2.1 Packing List The SU-I units are shipped with the following units and accessories. The exact packing list varies depending on system configuration and ordered equipment. • • • • SU-I unit A 5 VDC universal power supply transformer Mounting bracket for wall or ceiling installation A torque key for antenna connectors 2.
Basic Installation 2.3 Installation Overview Standard installation involves the following steps: 1. Verify that all components of the packing list, described in Section 2.1, are intact and verify availability of the required items listed in Section 2.2. 2. Install the unit and antenna(s) in optimal locations as described in Section 2.4. 3. Connect the antenna(s) to the unit as described in Section 2.6. 4. Connect the power supply to the unit as described in Section 2.7. 5.
Basic Installation 2.4 Installation Guidelines This section describes the installation guidelines and the various considerations that must be taken into account when planning the installation. 2.4.1 Location of the Unit and Antenna(s) • The unit can be placed on a shelf, or can be attached to the ceiling or a wall using a mounting bracket. The unit should be installed as near to the antenna(s) as possible to minimize loss of RF power in the cable(s).
Basic Installation 2.4.3 Antenna Diversity In applications where no multipath propagation is expected, a single antenna is sufficient to ensure good performance levels. However, in cases where multipath propagation exists, BreezeCOM recommends that two antennas be used. This takes advantage of space diversity capabilities. By using two antennas per unit, the system can select the best antenna on a per-packet basis (every several milliseconds).
Basic Installation building is more forgiving than protection of electronic devices. A building can withstand up to 100,000 volts, but electronic equipment may be damaged by just a few volts. Lightning protection entails connecting an antenna discharge unit (also called an arrestor) to each cable as close as possible to the point where it enters the building. It also entails proper grounding of the arrestors and of the antenna mast (if the antenna is connected to one).
Basic Installation 2.5 Wall Mounting the Unit Use the supplied brackets for wall mounting to install the unit on a wall or a ceiling. 1. Turn the unit so the rear panel is facing you. 2. Unscrew the two screws located at the antennas end of the unit (the top screws). 3. Align the Unit Mounting Slots (see Figure 2-2) with the slots you have just unscrewed. 4. Using the longer screws supplied with the wall mounts, screw the wall mount to the unit. 5.

Aligning the Antenna 4. ALIGNING THE ANTENNA Omni and low gain antennas do not require alignment due to their wide radiation pattern. High gain antennas have a narrow beamwidth, necessitating an alignment procedure in order to optimize the link. For Subscriber Units with directional antenna(s), you can either use the LED indicators on the front panel of the unit or view the Received Signal Strength Indication (RSSI) on the monitor. In most installations, alignment using the LEDs is sufficient.
Aligning the Antenna 4.2 Aligning the Antenna Using the Site Survey Menu 1. Start the Monitor program as described in Section 3.1. 2. From the main menu, type 4 to access the Site Survey menu. Type 4 to start the Continuous RSSI Display. Each line in the display includes the number of frames that were received since the last measurement (total Rx) and the average RSSI for these frames. 3. Rotate the antenna left and/or right until you reach the point of maximum RSSI reading.
Maximum Data Rate Configuration 5. MAXIMUM DATA RATE CONFIGURATION 1. If the average RSSI reading using the Average RSSI Continuous Display is lower than 76, the default data rate of 3 Mbps is too high and the data rate of the unit should be configured accordingly: 2. From the main menu, type 3 to access the Basic Configuration menu. Type 5 to access the Maximum Data Rate menu. i) Type 3 (3Mbps) if the RSSI reading is higher than 76 units. ii) Type 2 (2Mbps) if the RSSI reading is between 66 to 76 units.

Appendix A APPENDIX A. OPTIONAL RF ACCESSORIES This appendix introduces some of the accessories available for specific installations, and describes how to install them. A.1 TPA 24 Transmit Power Amplifier (Booster) The TPA 24 Transmit Power Amplifier is used to amplify the transmit power to a fixed output of 24 dBm (250 mW). The TPA 24 is especially useful when long RF cable runs are required. In addition, the TPA 24 simplifies antenna alignment by enabling the use of wider dispersion transmit antennas.
Appendix A A.1.1 Installing the TPA 24 1. Choose one of the TPA 24 models according to the power level at the input of the booster. In general the NH model is used. For installations with long cables (high attenuation), the NL model should be used. 2. Choose one of the antenna connectors to be used for transmission. 3. Use the terminal to set the unit’s transmit diversity option to the selected antenna. Figure A-1. TPA 24 Installation 4. Connect the TPA 24 RF output directly to the transmit antenna. 5.
Appendix A 7. Plug the power cable leading from the Power Inserter into any available 110/220V outlet. The power supply must be installed indoors. 8. For reception, use a separate antenna connected to the other antenna connector of the BreezeACCESS unit. Note: Installations exceeding regulations set by local authorities expose the installer and the user to potential legal and financial liabilities. A.1.
Appendix A A.2 LNA 10 Low Noise Receive Amplifier The LNA 10 is a high-performance, low-noise preamplifier designed to enhance fringe area reception and provide additional gain on the receive antenna. Its exceptionally small size and light weight enables it to be directly mounted on the antenna by means of the female RF IN connector. Power is obtained through an RG-59 coaxial cable connected to the power supply. The LNA 10 is internally protected against lightning and voltage surge protection.
