SAFETY WARNINGS
Throughout this manual, important safety warnings are included to warn of possible
hazards to persons or equipment. A safety warning identifies a possible hazard and
then describes what may happen if the hazard is not avoided. The safety warnings
in the form of Dangers, Warnings and Cautions must be followed at all times. These
warnings are flagged by the use of a warning icon, usually the triangular alert icon
seen below. The exclamation point within the triangular alert icon i s intended to warn
the operator or service personnel of operation and maintenance from factors related
to the product and its operating environment, which could pose a safety hazard.
GENERAL SAFETY WARNINGS CONCERNING USE OF THIS SYSTEM
Always observe standard safety precautions during installation, operation and
maintenance of this product. Only a qualified and authorized personnel should carry

1 INTRODUCTION
Deko4078SD Digital Multi-Channel Signal Booster provides cost effective indoor and
outdoor communications coverage for the complete 700/800MHz Public Safety
spectrum assigned to the wireless networks.
Deko4078SD meets public safety infrastructure design requirements that include
higher base station site elevation, higher power output per channel, transmission
only on traffic channels that are in use and single receiver omni-directional site.
The system supports advanced Digital Signal Processing (DSP) technology,
programmable digital filters - where each filter supports up to 24 channels, and
programmable bandwidth of up to 12 MHz. These capabilities enable the user to
quickly and simply customize the Booster according to changing site requirements.
A SmartALC power control algorithm automatically optimizes the gain setting by
learning the actual range of RSSI levels over a user-specified period of time. The
SmartALC algorithm prevents oscillations, reduces the amount of isolation required
by the system and optimizes the system to minimize noise rise at the donor c ell site.
An intuitive GUI based Management Tool (RMT) provided with the Booster is used to
configure, monitor and manage the Booster through an Ethernet connection to the
system.

PRODUCT MANUAL DEKO4078SD MULTI-CHANNEL SIGNAL BOOSTER DEKOLINK WIRELESS LTD.
3.3 CONNECTING THE DONOR AND SERVICE ANTENNAS
CAUTION
DO NOT CONNECT THE ANTENNA CABLES TO THE BOOSTER BEFORE VERIFYING THE INSTALLATION
PARAMETERS - SPECIFICALLY THE ISOLATION BETWEEN THE ANTENNAS.
DO NOT POWER-ON THE BOOSTER (USING THE INTERNAL SWITCH) WITHOUT EITHER THE
ANTENNAS BEING CONNECTED OR THE ANTENNA CONNECTIONS TERMINATED WITH DUMMY LOADS.
Note: If the coaxial cables are NOT weather-resistant type, wrap the exterior coaxial
cables with insulation and holding tape (Type 3M Rubber splicing tape) for
environmental protection and to ensure longer lifetime.
To connect the antennas to the Power Amplifier
1. Install the antenna cables along their path to the Power Amplifier unit, and
connect them to the Antennas.
Note: Be sure to use low loss cables.
2. Connect the Donor antenna to the BASE port.
3. Connect the Service antenna to the MOBILE port.
4. Verify all RF connectors are tightened and the cables and antennas are secured

P/N 300SC30031 Rev. 1.2 Proprietary Data Page 19
PRODUCT MANUAL DEKO4078SD MULTI-CHANNEL SIGNAL BOOSTER DEKOLINK WIRELESS LTD.
3.4 VERIFYING GROUND CONNECTIONS
All of the units’ grounding lugs are located on the left side of their rear panels. The
Deko4078SD units’ ground connections are interconnected and the final grounding
connection is performed to the cabinet rack grounding lug located on the left side of
the bottom shelf (accessed from the rear). See below.
Figure 9. Final Grounding Connection
In addition, it is required to connect the rack ground to the building ground.
3.5 POWER UP
Be sure that grounding is performed properly and
that all required RF connections (Donor and Service
antennas in case of a supplied cabinet installation)
1. Connect the power connector on the Power Supply rear panel to a 220/110 VAC
power source.
2. Maintain the Main unit in idle state (after power up) for approximately one or
two minutes. This time lapse is required for the CPU boot up. After the boot-up
process is complete, the SYSTEM READY GREEN LED will light.
3. Verify that the PWR ON LED on the Main unit front panel is GREEN.

4 COMMISSIONING THE SYSTEM
This section provides the initialization and setup procedures for the Deko4078SD
signal booster. The procedures are performed through an Ethernet connection
between the Deko4078SD signal booster and a computer.
Note. This chapter only describes the parameters required to provision the Deko4078SD
signal booster. The application window options are fully described in Chapter- 5 .
4.1 OPENING A SESSION
4.1.1 CONNECTING THE SIGNAL BOOSTER TO THE COMPUTER
To open connect the Signal Booster to the Computer
Connect the Ethernet cable (supplied) between the Main units’ front panel Ethernet
port (see figure below) and the computer Ethernet port.
Figure 10. Connection to Computer

4. In the Items list, select “Internet Protocol (TCP*IP)” and click the
Properties button. The “Internet Protocol (TCP/IP) Properties” dialog appears.
Note: The Booster is supplied with the default IP address 192.168.1.253.
5. Assign your computer an IP address in the same subnet, in order to
communicate with the unit.
• In the IP address area:
• Enter the IP address 192.168.1.x, where ‘x’ can be any number between 2 and
250 inclusive. For example, (192.168.1.9)
• Define the subnet mask as shown (255.255.255.0)
• Click OK.
The computer communication parameters are now defined and you can open a
session to the Booster.
4.1.3 LOGIN TO THE SIGNAL BOOSTER
NOTE: The booster is factory assigned the address 192.168.1.253. You will login for the
first time using this address and make the necessary modifications according to
information provided by your network administrator.
To login to the booster
1. Open one of the Flash-enabled browsers listed in the system requirements.
2. In the address line, enter the provided IP address of the Booster. A session will
be established with the Booster an the login dialog appears.

3. Type the default User Name admin and the default Password admin
Note: Both User name and Password are case sensitive and must be entered with
lower case letters.
4. Click Login. The application main window appears.
4.2 COMMISSIONING THE SYSTEM
The commissioning procedure consists of the following steps
1. Configuring the Booster parameters
2. Verifying that there are no alarms in the alarms area of the management
application and configuring the signal booster general parameters.
3. Configuring the required filters
4. Configuring the Modem parameters (if installed)

Note: The number of filters that can be defined depends on the selected DL Routing
configuration (see 4.2.1 step 4). For example, if the 12 filters for 700MHz, 12 Filters for
800MHz option was selected then the maximum number of filters that can be added for
each band is 12.
