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.
