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.

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.

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.

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.
Chapter 2. Pre-Installation Tasks 25
CPN 63179 Issue Date: 01/24/03
Tsunami Multipoint Version 1.3 Installation Guide
▪ Install the BSU first before installing any SUs.
▪ Once a link has been established, check the RSL at the SU, and if too high, miss-point the antenna
slightly to reduce the receive power.
Configuring the Base Station
Keep in mind the following when configuring a BSU:
▪ The configuration commands are NOT case-sensitive.
▪ Refer to the Operator Commands section of the software’s Help menu (or the Reference manual)
for additional information on command syntax.
▪ The BSU does not provide an on-screen response to many of the available commands.
▪ The BSU saves the configuration settings periodically (approximately every two minutes). Therefore,
after issuing the last configuration change, wait two minutes before recycling power or turning off the
unit to ensure that all of your changes take effect.
To configure the Base Station:
1. On the computer that has the Base Station Configuration Software installed, change the IP address
for its Ethernet card to 192.168.20.xx with a 255.255.255.0 subnet mask (xx can be any number
between 1 and 255 with the exception of 254). The computer and BSU must be members of the same
IP subnet to communicate. When using the Multi-BSU software, the BSU and SU can be on different
subnets (see “Using the Multi-BSU Configuration Software” in the Tsunami Multipoint Version 1.3
Reference Manual for information).
Note: The BSU’s default IP address is 192.168.20.253 with a subnet mask of 255.255.255.0.
2. Run the Base Station Configuration Software on the computer. To do this, from the Windows Start
menu, select Programs Æ Base Station Configuration Software.
Note: The menu bar reads “Base Station Configuration Software” when the computer and BSU are connected to
the same physical network. If the menu bar reads “Configuration Software” only, the two devices are not
on the same physical network; confirm that they are connected to the same Ethernet network, check the
Ethernet cables, and confirm that the BSU is powered on before continuing.
º Type dspconf and press the Enter key to view the BSU’s current configuration settings. If you do
not get a response to this command, confirm that the computer and BSU are on the same IP
subnet.
Chapter 2. Pre-Installation Tasks 26
CPN 63179 Issue Date: 01/24/03
Tsunami Multipoint Version 1.3 Installation Guide
3. Configure the BSU’s IP settings:
Type setIP <IP address> and press Enter, where <IP address> is the new IP address you want to
assign to the unit. For example, type setIP 192.168.20.20 to assign this IP address to the BSU.
A. Close the Base Station Configuration Software and change the IP address of the computer’s
Ethernet card so that it is in the same IP network as the BSU’s new IP address; restart the
computer if necessary.
B. Open the Base Station Configuration Software and use the dspconf command to verify that the
BSU and computer can communicate.
C. Enter setSubnet <subnet mask> where <subnet mask> designates a subnet mask. Proxim
does not recommend using a subnet mask wider than 255.255.248.0.
D. If desired enter gateway <gateway address> where <gateway address> designates the IP
address of the network’s gateway.
4. To set the BSU’s Terminal ID, enter setID <Terminal ID> where <Terminal ID> is a number
between 1 and 2048). For example, setID 1 sets the unit’s Terminal ID to 1.
Note: Each BSU and Subscriber Unit (SU) in a cell must have a unique Terminal ID.
5. Use the setFrameSync command to set the proper GPS operating mode.
º When performing indoor tests, Frame Sync must be set to Independent mode (setFrameSync
1). A BSU’s transmitter does not turn on if Frame Sync is set to Multi Sector while indoors.
Frame Sync should be set to one of the Multi Sector modes only when multiple BSUs are installed
in the field; these modes enable a BSU’s GPS receiver so it can synchronize its frame timing with
other BSUs. See “Configuring the System for Multi-Sector Mode” on page 29 for details about
configuring and testing multi-sector operation.
6. If Range Security is enabled (set to 1), enter rangeSecurity 0 (zero) to disable this feature. You can
enable it later once the SUs have been installed in the field.
7. Set the desired data rate using the modulation command (modulation <0 (60Mbps) | 1 (40 Mbps) |
2 (30 Mbps) | 3 (20 Mbps)>). This step is not applicable for BSUs that support 20 Mbps operation
only.
º Set the desired frequency plan using the freqPlan command. (freqPlan < 4 (four channel | 5
(channel) | 6 (channel)>). Tsunami Multipoint offers several frequency plans and operating
frequencies to provide a means for overcoming interference. If one part of the 5.8 GHz spectrum
is occupied when you deploy the product, you can select a different frequency plan to bypass the
interfering frequency.
Chapter 2. Pre-Installation Tasks 27
CPN 63179 Issue Date: 01/24/03
Tsunami Multipoint Version 1.3 Installation Guide
8. Set the desired frequency plan using the frequency command. (frequency < a | b | c | d | e| f >;
with e being available for the 5 and 6 channel plans and f being available for the 6 channel plans
only.
9. Set the BSU’s desired transmit power level using the txPowerLevel command.
Note: Typically the power level is set to 17 dBm in the field (maximum setting) and 6 dBm for indoor range
testing (minimum level).
10. Set the desired transmit power auto-enable mode with the txPowerAutoEnable command
(txPowerAutoEnable < 0 (off) | 1 (on)>. When auto-enable is set to on the BSU will automatically
start transmitting after any power cycle.
11. Set the desired routing mode with the routingMode command. (routingMode < 0 (IP routing | 1
(Bridging)>).
Note: After you issue the routingMode command, you may need to clear the PC’s arp table. (restarting the PC
used to configure the BSU will do this).
12. Turn on the BSU using the txPower command (txPower <0 (off) | 1 (on)>).
At this point the BSU is configured and ready to operate. Also, see “Advanced Configuration Options” and
“Command Reference” in the Tsunami Multipoint Version 1.3 Reference Manual for information about the
other commands used to configure the BSU (such as setting proxy, RIP, static IPs, and so on).
Adding Subscribers to the BSU Database
Subscriber units will not be able to enter the network until they are added to the BSU database.
1. Identify the Subscriber Units (SUs) you intend to use with this BSU and write down each device’s
MAC address (which is printed on the product label).
2. Add the first SU to the BSU’s database by entering addSU <MAC address> <Terminal ID>.
º When typing the MAC address, separate each pair of digits with a colon or a blank space.
º The Terminal IDs range from 1 to 1023; assign a unique ID to each BSU and SU in a cell.
For example, if the SU’s MAC address is 00-04-44-12-34-56 and you want to assign Terminal ID
2 to this SU, enter addSU 00:04:44:12:34:56 2.
Note: Add an SU to the BSU’s database before installing or turning on the SU.
Chapter 2. Pre-Installation Tasks 28
CPN 63179 Issue Date: 01/24/03
Tsunami Multipoint Version 1.3 Installation Guide
3. Configure the SU’s IP settings:
º Enter setSUIP <Terminal ID> <IP address> to set the SU’s IP address. Proxim suggests that
you configure each SU with a unique IP address in the same IP subnet as the BSU in Bridging
mode and configure each SU with a specific subnet in IP routing mode.
º Enter setSUSubnet <Terminal ID> <subnet mask> to set the SU’s subnet mask.
4. Repeat Steps 2 and 3 for each SU that you want to add to the Tsunami Multipoint system.
5. Enter dspSU to view the list of SUs that have been added to the BSU’s database.
6. Install the SUs as described in “Chapter 3. Deploying the Subscriber Unit” on page 31.
Configuring the System for Multi Sector Mode
If you are installing the BSU in the same geographical location as other BSUs, i.e., in a location where
one BSU may interfere with another, set the unit to Multi Sector mode; this enables the GPS receiver.
GPS is used to ensure that all BSUs in the same geographical region transmit and receive at the same
time. In additional, the ratio of downlink to uplink slots must be the same for all BSU’s that may
interfere with each other. Together, these eliminate the possibility of a BSU transmitting while a co-
located BSU is receiving. This synchronization is achieved using the timing signal supplied by the GPS
receiver. The GPS receiver needs to see four satellites to obtain an accurate time. Once time has been
initialized, the receiver can keep accurate time even if it sees only a single satellite.
There are two multi-sectors modes; auto-restart and auto-resync. The difference between these modes
has to do with how the BSU synchronizes its timing to gps after an outage. The reader is referred to the
TMP reference manual for more details. To configure the BSU for Multi Sector Mode, use the
setFrameSync command (setFrameSync <0 (Multi-sector with auto-restart | 1 (independent – NOT
multisector) | 2 (multi-sector with auto-resync). Multi-sector mode with auto-resync is the recommended
mod). To turn off Multi Sector Mode, enter setFrameSync 1, indicating Independent (GPS is not used).
Testing the GPS Receiver
The GPS Receiver Test examines the quality of the GPS signal. This test is for use only in the field by
customers who have installed multiple Base Station Units (BSUs) in the same location (with the Frame
Sync parameter set to Multi Sector).
This tool tests the GPS quality for BSUs that receive timing information from GPS satellites.
Note: The BSU must have the GPS antenna connected to receive GPS signals. See “Mounting the GPS Antenna.”
Chapter 2. Pre-Installation Tasks 29
CPN 63179 Issue Date: 01/24/03
Tsunami Multipoint Version 1.3 Installation Guide
Follow these steps to run the test:
1. Open the Base Station Configuration Software.
2. Enter BSUlog 1 1.
3. The second output column is GPS sync, which will read –1 until the GPS can acquire the requisite
number of satellites. When this number reads 0, GPS has acquired at least one satellite; when it
reads 4, at least four satellites have been acquired and GPS is functional.
4. Enter BSUlog 0 to turn off BSU log.
5. Enter pp3d 1 to start the GPS test.
º The Base Station Configuration Software reports the following values (from left to right):
Column 1: Time error in half-chip; this value should be less than 80
Column 2: Frequency error
Column 3: Synchronize filter; this value must equal 20
Column 4: Not applicable
Column 5: GPS message; this value must be 4
Column 6: Visible sat; this value must be 4
Column 7: Time of week in 10 ms
Columns 8 & 9: Not applicable
º Column 1 provides information concerning the level of frame synchronization and Column 6
provide information about the number of visible satellites.
6. Enter pp3d 0 (zero) to end the GPS test.

Attempt to ping from a computer connected to:
▪ An SU to the BS (BSU and SU must have different IP addresses to do this. If the BSU and SU are
configured with the same IP address, the local unit responds to the ping (that is, if the BSU and SU
have the same IP address and you ping the BSU from a host connected to the SU, the SU responds to
the ping).
▪ The BSU to the SU. (BSU and SU must have different IP addresses to do this. If the BSU and SU are
configured with the same IP address, the local unit responds to the ping (that is, if the BSU and SU

If the ping tests are unsuccessful, attempt the following:
▪ Check all IP and computer configurations (for example, if you attempt to ping the BSU from the SU
configuration computer and the BSU and SU’s are in separate networks you must have the
configurations computers gateway set to the SU for the ping to work.)
▪ Adjust the network’s IP settings, if necessary, to achieve IP connectivity.
If the above fails refer to “System Diagnostics” to help debug possible link problems.
Note: See “Chapter 4. System Diagnostics and Operating Tips” on page 40 for information about running system
