Tsunami Multipoint Version 1.3 Installation Guide Mounting the BSU to a Pole To mount the BSU to a pole using the attached mounting components: 1. Lash the unit to the pole or use a hoisting rope to keep the unit in place while you mount it. Slide the two strap clamps over the two sets of 1/2-13x7 1/2 screws and secure the strap clamps using four #1/2 split lock washers and four 1/2-13 hex nuts (see the following photo). Figure 13. Strap Clamps Attached and Mounted BSU 2. To adjust the up/down tilt (-10 to +5 degrees), move the top or bottom of the BSU (depending on how you installed the downtilt/notched bracket assemblies) until the unit is roughly positioned at the correct angle. 3. Connect the supplied Cat 5 cable to the BSU’s Power and Ethernet port as described in the following notes. Then screw on the outer ring to secure the cable in place. Figure 14. BSU’s Power and Ethernet Connector Chapter 2. Pre-Installation Tasks 21 CPN 63179 Issue Date: 01/24/03
Tsunami Multipoint Version 1.3 Installation Guide The Base Station Unit (BSU) is shipped with a dust cover over the large 18-pin connector. Keep this cover on until ready to mate with cable connector to avoid getting the connector wet. To ensure proper weatherproofing, follow these procedures to connect the supplied Cat 5 cable to the BSU’s Power and Ethernet port. A. Check the BSU connector. The only moving part should be the plastic nut (“B”), which screws onto the BSU housing. B. If there is any movement or play between parts A and C, you must tighten these parts before proceeding; otherwise you could cause connector pins to disconnect or break when you apply the weatherproofing tape. To tighten, first loosen (but do not remove) the connector’s screws (indicated with arrows in the previous figure). C. Then, while holding the pin connection portion (1), turn the bottom portion (2) clockwise until there is no more movement, making sure you do not over-tighten. D. Re-tighten the screws. E. When mating the BSU to the cable connector, first apply a bead of silicone grease or RTV to the 3mm-wide outward-most flange on the BSU connector (or in the outer ring of the cable-end mating connector). F. Then tighten the plastic nut on the cable end to 16 inch-lbs (1.81 N-m). The cable connector must be tightened onto the BSU sufficiently to compress a small O-ring that resides inside the male BSU connector. If the O-ring is missing or insufficiently compressed, moisture can get through into the connector pins. Chapter 2. Pre-Installation Tasks 22 CPN 63179 Issue Date: 01/24/03
Tsunami Multipoint Version 1.3 Installation Guide Once mated, over-wrap the connectors (as demonstrated in the following table) with stretchy black self amalgamating tape (such as CTB-15 CATV TAPE-X5-BK-UN part #22150000 from DSG – CANUSA 173, Commerce Boulevard, Loveland, Ohio 45140, Tel. 1-800-422-6872) to ensure a better water seal. 1) 2) 3) 4) 5) 6) 4. Connect the other end of the Cat 5 cable to the BSU’s power supply. (The BSU’s power supply is ordered and shipped separately. The power supply’s CPN number is 58526.) 5. Plug the power supply into an electrical outlet. Note: To ensure proper grounding, use the hole on the back of the BSU and the provided grounding screw to attach a ground wire to the BSU. Use wire grounding techniques in accordance with your local electrical codes. Chapter 2. Pre-Installation Tasks 23 CPN 63179 Issue Date: 01/24/03
Tsunami Multipoint Version 1.3 Installation Guide Installing the GPS Antenna If you do not plan to install multiple BSU in the same geographical area skip this section If you plan to install multiple BSUs in the same geographical area (for example, one BSU might interfere with another), you must install the supplied GPS antenna (a small metal plate with a black 2"x 2" antenna and thin cable) on each BSU. Each BSU uses a global positioning system (GPS) to synchronize its clock with other BSUs. You also must set each BSU to Multi Sector mode (see “Configuring the System for Multi-Sector Mode” on page 29). Mounting the GPS Antenna To install the GPS antenna: 1. Position the GPS antenna in a location where the antenna plate is parallel to the earth/horizon and the black antenna bump-up can be attached to the BSU (as shown in the following figure). The GPS antenna should be exposed to as much of the sky as possible so it can acquire at least four GPS satellites to extract timing signals for the BSU transmission synchronization. Figure 15. GPS Antenna Mounted on BSU 2. Insert the band clamp through the slots in the GPS antenna-unit mounting bracket and around the mounting pole. Tighten the clamp around the mounting pole and then tighten the screw in the clamp to secure the GPS antenna mounting bracket to the mounting pole. 3. Attach the GPS antenna to the GPS antenna mounting bracket using the #10-32x3/8 SEM screws (the screws with attached washers). Chapter 2. Pre-Installation Tasks 24 CPN 63179 Issue Date: 01/24/03
Tsunami Multipoint Version 1.3 Installation Guide 4. Remove the water-protection cap from the top of the BSU and screw on the cable from the GPS antenna to the connector on the top of the BSU. Installing BSU Configuration Software The next step is to configure the BSU. The BSU is configured from a PC running the BSU Configuration Software (Versions 1.4 or 1.5). This PC communicates with the BSU through its Ethernet port. If you have a PC with the BSU Configuration Software already installed, skip to “Configuring the Base Station” on page 26; otherwise, install the BSU Configuration software as described in “Appendix B. Installing the Software and Upgrading Firmware” on page 51. Operating in a Test Environment Prior to installation outdoors, you may want to operate the equipment indoors in a test environment to become familiar with the operating configurations and performance. Furthermore, in situations in which it is extremely difficult (very low temperature) or costly (on a mountain top) to install or replace the equipment, you may want to verify operation in an indoor test environment prior to actual installation in the field. All of the configuration and testing information described in the previous chapters, with the exception of the actual mounting of the units, apply to an indoor test deployment. The following sections describe a procedure to set up a pre-installation testing environment for this purpose. Warnings and Considerations for an Indoor Deployment Review the following important warnings and considerations before turning on any Tsunami Multipoint equipment indoors in your test environment. WARNING! All persons should be at least 5 feet (1.5 meters) away from any antenna when any products are operational. Place the antennas at least 30 feet apart, facing each other. ▪ To minimize the multi-path phenomenon, the BSU should be configured to use the lowest transmit power level (6 dBm) and the most reliable modulation technique (20 Mbps mode). In addition, the BSU must have GPS and Range Security disabled. Also, make sure the BSU is facing toward the SU. ▪ Do not set up your laptop between the antennas or stand between the antennas. ▪ Try to minimize the movement of objects within the test environment to prevent changes in radio propagation patterns. Radio signals behave differently indoors than outdoors; using the devices indoors may have an unintended, negative effect on the performance of the Tsunami Multipoint system. ▪ For best results, connect at least one computer to the BSU and to each SU.
