OVERVIEW

Signal boosters extend radio coverage into areas

where abrupt propagation losses prevent reliable

communication. The system receives an RF signal,

raises its power level, and couples it to an antenna

so that it can be re-radiated. The TXRX model

6138X family of channelized signal boosters is

designed to operate in either the 700 or 800 MHz

range. Dual band models are available that include

both 700 and 800 MHz systems in the same enclo-

sure box. The system is based on a module design

with each module capable of handling 14 or 30 car-

riers in the uplink and downlink direction. The sig-

nal booster is available in a variety of

configurations as shown in Table 1. The product

model number is used to describe each configura-

tion available. Model number nomenclature is

described in table 1.

The size of the system can be tailored to the cus-

tomers needs by increasing or decreasing the

number of carriers used. Each module is bi-direc-

tional with one downlink and one uplink signal

branch. Each of the two branches in a module are

independently tunable to their required pass fre-

quencies via software interface. System specifica-

Down / Up Conversion

A channelized signal booster has much in common

with a superheterodyne (superhet) receiver. The

incoming signal is converted to a lower frequency

so that single channel selectivity can be obtained.

It is then filtered. Unlike the superhet receiver how-

ever, the signal is not demodulated. Instead, it is

up-converted back to its original frequency where it

is further amplified to reach a useful power level.

Figure 1 shows a simplified block diagram that

illustrates the down/up conversion principle. An

incoming signal at (Freq IN) is amplified and

applied to the first mixer along with a signal from a

local oscillator (Freq LO). A third signal at an inter-

mediate frequency (Freq IF) is produced as a result

of the mixing. The intermediate frequency is given

by the following relationship:

(1) Freq IF = Freq IN - Freq LO

The IF signal from the mixer then passes through

digital filtering with single channel bandwidth

before being amplified and passed on to the sec-

ond mixer. The second mixer also receives the

same local oscillator signal (Freq LO). The result is

a mixing product frequency at the output of mixer 2.

The output frequency (Freq OUT) is given by the

following relationship:

(2) Freq OUT = Freq IF + Freq LO

Substituting equation (1) for the “Freq IF” term in

equation (2) allows the “Freq LO” terms to be can-

celed yielding:

(3) Freq Out = Freq IN

The implication of equation (3) is that the frequency

stability of the signal that is processed by this type

of signal booster is not affected by the frequency

stability of the signal booster itself. Frequency sta-

bility depends only on the stability of the signal

source producing the signal to be boosted. A shift

in the LO frequency will cause the center of the fil-

ter bandwidth to move with respect to the signal.

For very narrow filter widths, the channel modules

LO may be locked to a high stability 10 MHz refer-

ence.

UNPACKING

It is important to report any visible damage to the

shipping company immediately. It is the customers

responsibility to file damage claims with the ship-

ping company within a short period of time (1 to 5

days). Care should be taken when removing the

unit from the packing box to avoid damage to the

unit.

INSTALLATION

The following sub-sections of the manual discuss

general considerations for installing the booster. All

work should be performed by qualified personnel

and in accordance with local codes.

Location

The layout of the signal distribution system will be

the prime factor in determining the mounting loca-

tion of this unit. However, safety and serviceability

are also key considerations. The unit should be

located where it can not be tampered with by the

general public, yet is easily accessible to service

personnel. Also, consider the weight of the unit and

the possibility for injury if it should become

detached from its mounting for any reason.

The booster needs to be installed such that there

can be unobstructed air flow around the equip-

ment. Insure that the heat sink fins are unob-

structed. The various subassemblies within the

equipment cabinet will stay warm during normal

operation so in the interest of equipment longevity,

avoid installation locations that carry hot exhaust

air or are continually hot.

Mounting

Figure 2 shows the mounting hole dimensions and

layout for the cabinet. Mount the cabinet using 3/8”

(10 MM) diameter steel bolts (not supplied). We

recommend flat washers on both ends and a lock

washer under the nut. Nut and bolt mounting is

preferred to the use of lag bolts. Use backer blocks

where necessary to spread the force over a larger

area. In areas of known seismic activity, additional

devices such as tether lines may be necessary.

Because Bird Technologies cannot anticipate all of

the possible mounting locations and the structure

types where these devices will be located, we rec-

ommend consulting local building inspectors, engi-

neering consultants or architects for advice on how

to properly mount objects of this type, size and

weight in your particular situation. It is the custom-

ers responsibility to make sure that these devices

are mounted safely and in compliance with building

codes.

Connections

All RF cabling connections to the booster should

be made and checked for correctness prior to pow-

ering up the system. N(f) bulkhead connectors are

available at the top of the booster enclosure box for

connection to the system antennas. Make sure the

correct branch of the antenna system is connected

to its corresponding uplink/downlink connector or

the system will not work properly. Using high qual-

ity connectors with gold center pins is advised.

Flexible jumper cables made of high quality coax

are also acceptable for connecting to rigid cable

sections.

Caution: The ERP (effective radi-

ated power) from the booster sys-

tem must not exceed +37 dBm (5

Watts) in order to remain compliant

with FCC regulations.

Caution: The maximum continu-

ous input power level for this

booster is -20 dBm. Stronger input

signals will cause the unit to exceed

it’s IM specifications. Static input

signals greater than -10 dBm may

damage the unit.

Models of the booster are available for either AC or

DC operation. Based on the model number (see

table 1) the booster is designed to be plugged into

either a single phase AC line (110 VAC at 50/60

Hz) or a - 48 Volt DC source. A connector is avail-

able at the top of the equipment box for connecting

the AC or DC source voltage.

Antenna Isolation

Antenna isolation between uplink and downlink

should be measured before connecting the signal

booster to the antenna system. This step is neces-

sary to insure that no conditions exist that could

possibly damage the signal booster and should not

be skipped for even the most thoroughly designed

system.

Just like the feedback squeal that can occur when

the microphone and speaker get too close together

in a public address system, a signal booster can

start to self oscillate. This can occur when the iso-

lation between the Uplink and Downlink antennas

does not exceed the signal boosters gain by at

least 15 dB. Oscillation will reduce the effective-

ness of the system and may possibly damage

amplifier stages. Isolation values are relatively

easy to measure with a spectrum analyzer and sig-

nal generator.

REQUIRED EQUIPMENT

The following equipment is required in order to per-

form the antenna isolation measurements.

1) Signal generator for the frequencies of interest

capable of a 0 dBm output level. Modulation is

not necessary.

2) Bird Technologies “Signal Hawk” spectrum ana-

lyzer which will cover the frequencies of interest

and is capable of observing signal levels down

to -100 dBm or better.

3) Double shielded coaxial test cables made from

RG142, RG55 or RG223 coaxial cable.

MEASUREMENT PROCEDURE

To measure the antenna isolation perform the fol-

lowing in a step-by-step fashion.

1) Set the signal generator for a 0 dBm output level

at the center frequency of the boosters pass-

band.

2) Set the spectrum analyzer for the same center

frequency and a sweep width equal to or just

slightly greater than the passband chosen ear-

lier in step 1.

3) Temporarily connect the test leads of the signal

generator and spectrum analyzer together

using a female barrel connector, see Figure 3.

Observe the signal on the analyzer and adjust

the input attenuator of the spectrum analyzer for

a signal level that just reaches the 0 dBm level

at the top of the graticule.

4) Referring to figure 3, connect the generator test

lead to one side of the antenna system and the

spectrum analyzer to the other then observe the

signal level. The difference between the

observed level and 0 dBm is the isolation

between the sections. If the signal is too weak

to observe, the spectrum analyzer’s bandwidth

may have to be narrowed and it’s input attenua-

tion reduced. The isolation value measured

should exceed the signal booster’s gain figure

by at least 15 dB.

5) Repeat step 4 again with the signal generator

set at the passband edges in order to see if the

isolation is remaining relatively constant over

the complete width of the passband.

6) Repeat the isolation measurements if neces-

sary at other system passbands to determine

the overall minimum isolation value for the sys-

tem. Physical modification of the antenna sys-

tem maybe required in order to reach an

acceptable minimum value.

RF EXPOSURE

To comply with FCC RF exposure compliance

requirements, a separation distance of at least 69

cm must be maintained between the antennas of

this device and all persons. To comply with IC RF

exposure compliance requirements, a separation

distance of at least 100 cm must be maintained

between the antennas of this device and all per-

sons. This device must not be co-located or operat-

ing in conjunction with any other antenna or

transmitter.

EXPOSITION RF

Pour conformer aux exigences d'exposition de

SIGNAL FLOW BLOCK DIAGRAM

Figure 4 is the signal flow block diagram of the

standard channelized signal booster model 6138X.

Figure 5 shows the front view of the booster cabi-

net. The channel modules are bi-directional with

each module containing one downlink branch and

one uplink branch. The branches are functionally

identical because the same circuit board designs

are used in each branch. The uplink and downlink

branches may be programmed to any frequency in

the appropriate band.

Uplink and Downlink Input Signals

Uplink input signals (794 - 806 and 806 - 824) are

picked up by the DAS antenna and applied to the

triplexer. The uplink input signals pass through the

triplexer and are fed into a directional coupler

where they are distributed to the uplink input port of

both the 700 and 800 MHz channel modules.

Downlink input signals (764 - 776 and 851 - 869)

are picked up by the Donor antenna and applied to

the triplexer. The downlink input signals pass

through the triplexer and exit at either the 700 or

800 MHz output port. The 700 and 800 MHz down-

link inputs signals are then applied to the downlink

inputs of the respective 700 and 800 MHz channel

modules.

Channel Module

The uplink input signals and the downlink input sig-

nals are applied to a down-converter board when

they enter the channel module. Within the channel

module input signals are down converted, digitized,

styles of Channel modules available, a 14 channel

version and a 30 channel version. After DSP filter-

ing the analog signal is recreated and up converted

with an up-converter board to the original fre-

quency before being output from the channel mod-

ule at the downlink and uplink output ports.

Up converter boards are available in two different

styles including low level and high level. If the sig-

nal booster is a high-power model then a low level

up converter board is used in the channel module.

If the booster is a low power model then high level

up converter boards are used. Signal booster mod-

els that have the fiber-optic option installed in them

have enhanced down-converter boards that are

capable of dealing with the low level signals from

the optical conversion.

Uplink and Downlink Output Signals

Uplink and Downlink output signals leave the chan-

nel module at the UL OUT and DL OUT connectors

respectively. The 700 and 800 MHz uplink output

signals are combined with a directional coupler

then passed on to a power amplifier stage. The

output of the power amplifier is passed through a

triplexer then radiated from the donor antenna.

Note: When the booster is operated at the maxi-

mum uplink output power level the gain of the

donor antenna should be limited to +10 dBi.

Downlink output signals leave the channel module

and are applied to a power amplifier stage. The

output of the power amplifier is passed through a

triplexer then radiated from the DAS antenna. Note:

When the booster is operated at the maximum

downlink output power level the gain of the DAS

antenna should be limited to -4 dBi.

OPERATION

Power is applied to the channelized booster by

plugging in the AC or DC power cord (depending

on how the system was configured for input

power).

Subassembly LED’s

LED’s are located on several of the subassemblies

within the Booster cabinet. The function of each of

these indicator LED’s are listed in Table 3.

COMMUNICATING WITH THE BOOSTER

The booster provides Ethernet connectivity that

allows access to a web-based user interface for

communicating with the control board, program-

ming the individual channels, checking system sta-

tus, etc. Communications will require connecting

your laptop computer to the Enet connector on the

control board. Figure 6 shows the connector. A

standard Ethernet crossover cable is used to make

the connection between your laptop computer and

the booster cabinet. Refer to Appendix A at the

back of this manual for detailed instructions on how

to properly connect your laptop computer to the

Enet port of the booster.

System Summary Submenu

Once your laptop computer is properly connected

to the signal booster the web-based user interface

screen will appear as shown in Figure 7. This is

the System Summary page which shows the IP

and MAC address of the control module. On the

left-hand side of the page are a list of the major

submenus available to the user including System

Summary, Control Panel (see note below), Network

Configuration, SNMP Configuration, and User

Administration.

When the web-based user interface

first comes up, the Control Panel sub-

menu choice will not be displayed.

The user needs to go to the User

Administration submenu and type in

the default user name (admin) and

default user password (admin). After

the login function is performed the

Control Panel submenu choice will

appear.

Place your cursor over a particular submenu head-

ing and left click to make a selection. Each major

submenu page contains a group of related func-

tions. Without entering your user password the

user will only be allowed to view the pages how-

ever and will not be able to make changes without

entering a password. After entering a valid pass-

word via the Admin submenu the pages will switch

from read only to fully interactive and the user can

begin making selections and changes if desired.

Control Panel Submenu

The Control Panel submenu gives the user the abil-

ity to interface with and adjust the RF parameters

of the booster. Four tabs are available on the Con-

trol Panel Page including FILTERS, FILTER

DETAIL, LINK, and SYSTEM. When selected each

tab presents a new screen and each screen con-

tains groups of related functions. Selection is made

by placing your cursor over the tab and performing

a left click.

FILTERS TAB

The Filters page gives an overview of all the filters

associated with each branch in the booster system.

Refer to Figure 8. The link drop-down box allows

you to select which branch you want to overview.

Press the down arrow button and highlight the

desired branch. Each filter is accorded one row in

the display. The first row of displayed data is used

to provide a summation of the input and output

power for the branch. The parameters displayed for

each filter include; Center Frequency, Bandwidth,

Channel Enabled, Test Signal, Squelch, the Input

Signal Level as both a numeric value and a bar

graph, Maximum Allowed Output Level, and Output

Signal Level as both a numeric value and a bar

graph. Changes to the filters are made from the Fil-

ter Detail page.

The enable, test signal, and squelch boxes are

interactive on this display. Place a check mark in

the box when you want the function selected. Place

your mouse cursor over the box and left click. A

check mark placed in the box for enable, test sig-

nal, or squelch indicates that function is turned on

while no check mark indicates the function is

turned off. The All Filters area at the top of the

page allows the user to adjust the Maximum Out-

put Level of all the filters in a branch simulta-

NOTE

neously. Use the up or down arrow to set the level

change amount then press the submit button.

On start-up, the booster validates the

widths of programmed filters. If any

are configured wider than 75 KHz and

the booster is set to Class A mode an

error message as shown in Figure 9

will appear. The offending filter or fil-

ters must be corrected or the booster must be

switched to Class B mode. Refer to the System tab

discussion later in this manual for instructions on

switching from Class A to Class B mode of opera-

tion.

FILTER DETAIL TAB

The Filter Detail page is divided into three func-

tional areas. The first area includes a pair of drop

down boxes along with a row of command buttons

running down the left side of the screen. The sec-

ond area is a filter details area in the middle of the

screen. The third is a status area on the right side

of the screen as shown in Figure 10. Once you

have interactive access to the Filter Detail page

you can begin programming the individual filters

that you want the booster to pass in the uplink and

downlink direction.

The Filter Detail page is designed to interact with

one filter at a time. To program individual filters you

must select the branch and the filter of interest

using the Link and Filter boxes on the left side of

the screen. Once the filter has been selected for

interaction a label can be assigned to the filter by

typing into the name box. Three groups of charac-

teristics need to be defined including frequency

band, OLC, and filter specifics. Frequency band is

selected from a drop down list. Center Frequency

and Desired Output Power level must be entered

by the user by clicking in the box and typing in the

desired value. Likewise OLC style is determined

with a drop down box. The two choices are Custom

and APCO 25 Phase 2. OLC Hold time and OLC

Decay time must be entered by the user.

NOTE

Figure 8: The Filter Summary Tab.

Figure 9: Class A limit exceeded warning message.

TX RX Systems Inc. Manual 7-9485-1.9.1 10/26/17 Page 18

Filter specifics are selected from a drop down list

that includes Custom, 12.5 KHz, 25 KHz, 12.5 KHz

Low Delay, and XML File. Four parameters are

customer adjustable including Occupied Band-

width, Adjacent Channel Offset, Passband Ripple,

and Adjacent Channel Rejection. Delay time is cal-

culated by the software. The four adjustable

parameters are setup using the Design Filter tool,

see the following section of this manual for details.

If a filter passband is selected that

exceeds the Class A limit of 75 KHz

and Class B operation is not selected

(see discussion in System tab section

of this manual) then a warning mes-

sage will appear as shown in Figure

11. You must set the booster to the

Class B mode of operation if you have

any filter with a passband greater than

75 KHz.

Design Button

When the Design Filter button is pressed a custom

design template will be displayed as shown in Fig-

ure 12. Boxes for the four required filter parameters

mentioned earlier are shown along with a graphical

representation of the filter’s response curve. Enter

into the four boxes the parameters you want. Click

on the Estimate button at the bottom of the screen

and the software will calculate the Delay time for

you. Press the Design button to design the filter.

The rejection scale of the display can be changed

by making a selection from the “maximum plot

rejection” drop down list. Choices include -10, -50,

and -100 dB scale. When the display is to your sat-

isfaction and does not violate any parameter

ranges press the Save and Close button to exit

back to the filter detail screen then load the design

into the selected filter by pressing the Submit but-

ton on the filter detail page.

Status Area

The status area of the Filter Detail page uses sta-

tus indicators to let the user know whether the

channel is enabled, if the test signal is on, and if

the carrier squelch is on. When the status indicator

NOTE

Figure 10: Filter Detail Tab.

Figure 11: Invalid filter settings warning message.

TX RX Systems Inc. Manual 7-9485-1.9.1 10/26/17 Page 19

is illuminated the feature is on and when it is dark

the feature is off. The Carrier Squelch status indi-

cator will be green if the channel is squelched. The

Carrier Squelch status indicator will stay dark if

there is no squelching even if the Carrier Squelch

radio button is set to enabled. A test signal can be

generated for any channel within the system or

every channel simultaneously.

The output power box displays the output power for

the channel module. This value should be close but

not necessarily exactly the same as the “Desired

Output Level” discussed earlier. The box showing

output power is only displayed if the filter is giving

an output power. If the filter is not enabled or there

is no signal present then there would be no value

to display.

LINK TAB

The link page is divided into three functional areas

including a row of command buttons running down

the left side of the screen, a link and a settings

area in the middle of the screen, and finally a sta-

tus area on the right side of the screen as shown in

Figure 13. The link page is designed to interact

with one branch of a module at a time. The branch

that is selected for interaction is determined by the

Link box on the upper left of the screen. To change

the branch that you are going to interact with click

on the arrow to display the full drop down box.

Scroll down the list until the desired branch is high-

lighted and click on it. The data displayed in the link

area of the display screen will now be for the

selected branch.

Command Buttons

Clicking on a command button (located on the

extreme left-hand side of the page) performs the

associated task immediately. The Submit and

Reload buttons in the bottom left corner allow any

changes you make to the display/interface boxes to

be downloaded to the booster. The Submit and

Reload buttons act like a trigger sending any

changes you made in the interface boxes to the

Figure 12: The design filter interactive display screen.

TX RX Systems Inc. Manual 7-9485-1.9.1 10/26/17 Page 20

channel module as well as updating any displayed

data from the module, but only after the button is

pressed. Individual branches or all branches can

be enabled or disabled using the enable/disable

buttons. After an alarm condition is corrected the

alarm can be cleared by selecting the clear errors

button. Selecting the factory reset button will return

the system to the factory default settings.

Link and Settings Area

The link portion of the area displays status informa-

tion for the branch. The Settings area is a user

interactive area where the field engineer can pro-

gram the operating characteristics of the selected

branch. Each parameter in the settings area can be

changed by clicking in the box and typing in the

new values or by pointing at an arrow to display a

drop down box. Most of the adjustable parameters

have adjustment limitations as applicable.

The parameters include turning on/off the use of an

external 10 MHz reference signal when an external

reference is available. If an external reference is

not available then leave this feature off and the sys-

tem will operate from the internal 10 MHz signal.

The AGC Reference Level should be set to the cal-

ibration value which is -15 dBFS. The ADC refer-

ence level can be adjusted when excessively

strong input signals are present. The Maximum

Output Power is the desired output power level

from the booster for the selected branch. The Max

Gain allows the user to determine the maximum

operating gain of the booster. This can be adjusted

based on your antenna isolation.

The changes you make in the Settings area are

only applicable to the selected branch. After you

have made changes to the various parameters

press the Submit command interface button (lower

left corner of the screen) in order to copy the

changes into the channel module itself.

Status Area

The status area of the link page lets the user know

the status of the channel module and power ampli-

fier if a power amplifier is used in the system

design. The status for seven parameters are con-

veyed by the status indicator next to the parameter

name. When the status indicator is green it indi-

cates that the parameter is on and when it is black

it indicates the parameter is off. In the case of the

Alarm (Summed Alarm), ADC Overflow, and DAC

Overflow, the status indicator will turn red during a

fault condition.

Figure 13: The Link Tab.

TX RX Systems Inc. Manual 7-9485-1.9.1 10/26/17 Page 21

When the Summed Alarm indicator is

red, if the cursor is placed over the

indicator, a message tab will appear

briefly describing the reason for the

alarm condition.

Seven additional parameters are displayed with

numerical values. The first group of parameters

include; Enabled which indicates whether the

branch is on or off, Ext Ref which indicates whether

the system is running on an external or internal 10

MHz clock signal, and Down and Up LO Lock

which indicate if the down converter and up con-

verter local oscillators are synchronized to their

respective RF signals. The second group of param-

eters using a status indicator will be black under

normal conditions and will turn red to indicate a

fault. The Alarm indicator is a summed alarm and

will activate when either the module or power

amplifier temperature/current exceeds their nor-

mal range. Also, the Form-C contacts inside the

cabinet will change states. ADC or DAC Overflow

indicator shows that the input power to the branch

is too high.

If a fault occurs, press the clear errors

button on the left side of the page. If

the error reappears right away then

trouble shooting will need to take

place.

The first four numerical parameters are real-time

indications of the module and power amplifier tem-

perature/current values. AGC Attenuation updates

in real-time and provides an indication of what the

AGC is doing. Input Power is a summation of all the

input signals to the branch. Output power also

updates in real-time and indicates the composite

power output for the branch.

SYSTEM TAB

The system tab lists the control board software ver-

sions. A customer-designated location name can

be recorded and is useful in situations where multi-

ple boosters are used in the overall system design.

There is also a system logbook available on the

bottom of this page for use by field engineers when

working on the system. Refer to Figure 14.

NOTE

Figure 14: The System Tab.

TX RX Systems Inc. Manual 7-9485-1.9.1 10/26/17 Page 22

Oscillation Detection

This feature shuts off the output signals from the

booster for both the uplink and downlink whenever

an oscillation condition is detected. Oscillation

detection occurs whenever port to port isolation

falls down to 25 dB or less. For normal operation

the port to port isolation needs to be at least 10 dB

greater than the gain of the booster. There are four

modes of operation for the Oscillation Detection

feature including Ignore, Alarm, Shutdown, and

Shutdown/Retry.

In the Ignore mode the booster will ignore oscilla-

tion events. In the Alarm mode the booster will gen-

erate an alarm notification by illuminating (RED)

the alarm button on the Link Tab and illuminating

(RED) an LED indicator on the control module. The

Shutdown mode is the same as Alarm mode

except the booster shuts off the output signals in

both the uplink and downlink direction. The shut-

down continues until the filters are re-enabled and

the alarm is reset. The Shutdown/Retry mode is

the same as the Shutdown mode except the

booster will retry operation the number of times

specified by the user. This is called the retry limit

which is entered into the associated box on the

System Page. How long the booster waits between

each retry attempt is determined by the retry inter-

val. After the retry limit is reached, if the booster is

still experiencing an oscillation condition, the

booster will enter the regular shutdown mode. The

Shutdown/ Retry mode is useful in situations where

brief transient overdrive signals are occurring.

Class B Enable

In order to operate the booster with a filter pass-

band greater than 75 KHz the booster MUST be

configured as a Class B booster and the customer

must register the booster online with the FCC.

Class B operation is enabled by checking the box

labeled “Enable Class B Operation”. When the box

is checked a warning message will be displayed as

shown in Figure 15 reminding the user to register

the booster with the FCC.

Network Configuration Submenu

Values for IP Address, Netmask, the Gateway and

MAC Address are displayed on the network config-

uration page. Refer to Figure 16.

The network configuration page allows the user to

enable or disable DCHP. The Dynamic Host Con-

trol Protocol (DHCP) is a standardized networking

protocol used on IP networks for dynamically dis-

Figure 16: Network Configuration Submenu.

Figure 15: Starting Class B operation message.

TX RX Systems Inc. Manual 7-9485-1.9.1 10/26/17 Page 23

tributing network configuration parameters, such as

IP addresses for interfaces and services. With

DHCP, computers request IP addresses and net-

working parameters automatically from a DHCP

server, reducing the need for a network administra-

tor or a user to configure these settings manually.

The DCHP (Dynamic Host Configuration Protocol)

is either active or inactive. When DCHP is active

the values for IP address, netmask, and gateway

are set to zero. When the DCHP is inactive (default

setting from the factory) the IP address, netmask,

and gateway values can be modified by the user by

typing the desired values into the associated box

and pressing the submit button. The customer

should consult with their IT department to deter-

mine whether DCHP should be active or inactive.

User Administration Submenu

The User Administration submenu allows pass-

word protected access to the booster. The boxes

on this page are interactive. To make changes click

inside the box and a cursor will appear. Refer to

Figure 17. The user is queried for a User Name

and User Password. The default user name is

“admin” and the default password is “admin”. It is

recommended that once the booster system is

installed approved users with unique passwords

are loaded into the system and the default admin

user/password is deleted.

Once the correct user name and password are

entered then a menu box for creating a new user

will be presented. To create a new user enter the

new user name and associated password. Confirm

the new password by entering it again and then

press the Create User button. Make sure you write

down the new user name and password for safe

keeping. A menu box for deleting a user is also pre-

sented. To delete a user enter their user name in

the box and click on the Delete User button.

SNMP Configuration Submenu

Simple Network Management Protocol (SNMP) is

an Internet-standard protocol for managing devices

on IP networks. The SNMP feature is designed to

provide reliable internet notification of an alarm

occurrence or a change in operational status in the

booster. In order to configure the booster to send

SNMP messages (called traps) to a destination

device, such as your computer, the following values

need to be entered into the booster; System loca-

tion, the IP address of the destination computer,

Authentication type, User name, Password, and

Encryption type, and the Encryption passphrase.

Figure 18 shows the SNMP Configuration display.

The System location is a user defined string which

will be returned with every trap that is generated

and can assist the user in identifying which unit is

sending the trap message. The three destination IP

addresses that are entered into the table should be

Figure 17: User Administration Submenu.

TX RX Systems Inc. Manual 7-9485-1.9.1 10/26/17 Page 24

the IP addresses of the computers that you want

the traps to be sent to. These destination comput-

ers must have SNMP manager software installed

and running in order to receive the messages.

SNMP manager software installation into the desti-

nation computers is the customers responsibility.

Consult with your IT specialist for assistance.

Authentication type is used to verify that the person

receiving the trap is the person the trap is intended

for. Authentication type choices are NONE, MD5,

or SHA, with SHA being the strongest encryption

type. When using authentication and/or encryption

the User Name is the name of the person to

receive the trap. If not, this is the community name

of the trap receiver. The Password is a string used

to encrypt and authenticate the user. It is only used

when authentication and/or encryption types are

enabled. The Encryption type is used to protect the

contents of the message from unauthorized receiv-

ers. Encryption type choices are NONE, DES, or

AES, with AES being the strongest supported

encryption type.

The Agent ID is a value that uniquely identifies the

agent sending the traps. The agent is software

which runs on the device being monitored and in

this case is the signal booster. The SNMP man-

ager software receives the traps and can be run on

your computer or another server on your network.

For traps that use encryption and/or authentication

the manager needs to be configured to receive

traps from the specified agent ID. This number is

shown on the SNMP submenu page underneath

the table, refer to figure 18.

Whenever values in the SNMP Configuration

screen are changed you must click on the submit

button to save the changes.

INITIAL SNMP SETUP

When the booster is installed the SNMP feature

should be setup for proper communications. There

are several steps required for proper setup of the

SNMP feature as discussed below.

1) Connect a laptop directly to the booster. Refer

to Appendix A for detailed instructions on how

to make a direct connection. The booster is

shipped from the factory setup for static IP

addressing and with a default IP address of

“192.168.1.1”. The factory default subnet mask

is “255.255.255.0”. Change the factory default

IP address of the booster to one provided by

your IT department.

2) Use the Network Configuration to setup the

DHCP as either active or inactive. When DHCP

is inactive the deck will be using a static IP and

the user must enter values for IP address, net-

mask, and gateway. Make sure you consult with

Figure 18: SNMP Configuration Submenu.

TX RX Systems Inc. Manual 7-9485-1.9.1 10/26/17 Page 25

your IT department regarding setting DCHP

active or inactive.

3) Use the SNMP Configuration submenu page to

enter up to three destination device addresses.

These are addresses where the SNMP feature

will send trap messages whenever a qualifying

event takes place. Qualifying events include the

following;

A) Down Converter LO Lock Fail

B) UP Converter LO Lock Fail

C) ADC Overflow

D) DAC Overflow

E) General Alarm - over current, over temp,

and oscillation.

4) Setup the SNMP format using the SNMP Con-

figuration submenu page. Items that need to be

configured include Authentication Type, User

Name, Password, and Encryption Type. Consult

with your IT specialist for assistance.

5) Load the SNMP manager software into the des-

tination computer and configure the manager so

that it will be able to receive the SNMP traps.

6) Download MIB files from the Bird Technologies

website (www.birdrf.com) and load the MIB files

into your SNMP manager software. The MIB

files allow the SNMP manager software to sort

out the trap messages into an understandable

message format.

The signal booster supports several SNMP Config-

uration validation checks which help ensure the

configuration is setup in a logical format. The vali-

dation checks include;

A) If encryption is enabled but authentication is not

enabled a popup window will appear stating that

you must enable authentication when encryp-

tion is enabled.

B) If Authentication and/or Encryption is enabled

and a password is entered which is < 8 charac-

ters long an error message will be displayed.

C) If an IP address is entered but a User Name is

not entered a popup warning will appear but the

changes will be submitted.

D) If a User name is entered but an IP address is

not entered a popup warning will appear but the

changes will be submitted.

SNMP MANAGER EXAMPLE

SNMP manager software is designed to provide a

GUI style interface for the user so that traps sent

from the booster can be received and displayed for

viewing. The SNMP manager software chosen and

used by the customer is up to the customers dis-

cretion and as such may not exactly match the

example shown in this discussion. SNMP manager

software packages will need to be properly config-

ured in order to successfully receive messages

from the booster. Refer to the SNMP configuration

setup discussed earlier in this manual and ask your

IT specialists for assistance.

When a qualifying event occurs in the booster a

trap is formulated and sent to the destination com-

puter. A typical trap is shown in Figure 19. In the

example shown the trap messages are shown at

the top of the screen display. Three trap messages

have been received by this manager from a signal

booster. In this particular SNMP manager software

package if a trap message is selected the details of

that message are displayed in the lower portion of

the screen. The details show the raw message as it

was received by the manager while the upper box

shows the message after it has been interpreted by

the MIB files.

Creating an Alarm for Testing Purposes

In the example shown in figure 19 an alarm condi-

tion was generated in the booster in order to create

the trap messages shown. The booster was told to

generate its oscillator clock signals using an exter-

nal reference source but no external source was

connected to the booster. This is a quick and easy

way to create a temporary alarm for testing pur-

poses. This is accomplished via the Link Page dis-

cussed earlier in the manual. Select the ON radio

button labeled EXT 10 MHz Reference then click

the Submit button. Do not connect a signal source

to the external osc port on the control module. This

will cause the downlink and uplink oscillators in the

channel to shutdown and the booster will enter an

alarm condition. Please note that on-air signals will

be interrupted during this time. To clear the alarm

select the OFF radio button then click the Submit

TX RX Systems Inc. Manual 7-9485-1.9.1 10/26/17 Page 26

button and finally the Clear Errors button. This will

take the booster out of the alarm condition and

return it to normal operation.

IMPORTANT: The SNMP feature may

not send traps when the web page is

operational. It may hold the trap mes-

sages until the web page interface is

closed at which point it will then send

the traps to the destination comput-

ers.

ETHERNET CONNECTIVITY

The front panel User Interface connector on the

booster provides for 10/100 BASE-T Ethernet con-

nection using the TCP-IP protocol. This product

feature allows access to a web-based interface for

programming the individual modules within the

booster. The web based interface requires a JAVA

runtime environment (version 1.6.0 or later) to be

installed on your laptop. The JAVA software can be

downloaded free of charge from the Sun Microsys-

tems website found at “http://java.com/en/down-

load/index.jsp”. The channelized booster is

shipped from the factory with a default IP address

of “192.168.1.1”.

Two connection schemes are discussed including a

direct connection from your laptop computer to the

booster front panel as well as connecting the

booster to a networked environment. A direct con-

nection (at the installation site) should be estab-

lished the first time you interface to the booster

using the fixed IP mentioned above. Once the initial

communications are established the IP address in

the booster can be changed to permit a networked

connection (from a remote site such as your office).

Direct Connection

Your initial connection to the booster system should

be a direct connection to the front panel using an

Ethernet crossover cable. Figure A1 shows the

proper way to interconnect the equipment as well

as the pinout for a CAT-5 crossover cable.

REQUIRED EQUIPMENT

Cat-5 Crossover Cable

Laptop Computer with a network interface card

installed. In addition, the JAVA run-time environ-

ment version 1.6.0 or later, and a web browser

such as Internet Explorer must also be installed on

the laptop.

PROCEDURE

To connect your laptop computer to the front panel

LAN port and access the web page interface, per-

form the following steps;

1) Insure the JAVA runtime environment software is

installed on your laptop.

2) Connect your laptop network port to the LAN

connector on the booster front panel using a

standard CAT-5 Crossover cable.

The front panel LAN connector

has two built-in bi-color status

LED’s which will aid you in estab-

lishing communications. The

meaning of each LED is shown in

Table A1.

3) The left-most (LINK) status LED built-in to the

LAN port connector should illuminate amber or

green indicating that a good physical connec-

tion is established between your computer and

the booster.

4) Insure that your laptop’s IP address is compati-

ble with the default address of the signal

booster system. This may require changes be

made to the Ethernet adaptor address on your

laptop (refer to Appendix B). Your laptop’s IP

address will need to be set to “192.168.1.2”

along with a subnet mask of “255.255.255.0”.

The right-most (ACTIVITY) status LED built-in

to the LAN port connector will turn amber or

green indicating good TCP-IP communications

are established between the laptop and the

booster.

5) Launch your web browser software on the lap-

top.

address of the booster “http://192.168.1.1” and

press the ENTER key. The web page interface

to the booster should appear in your laptop’s

browser window. When you launch the web

page you may notice that the JAVA applet will

load first.

Networked Connection

Before attempting a networked connection to the

signal booster system consult with your IT support

personnel for information concerning the correct IP

address to use and any additional connectivity

issues such as firewalls. Once you have the correct

IP address you will need to direct connect to the

booster system as discussed in the earlier section

of this appendix and reconfigure the booster LAN

port with this new address. You can then connect

the signal booster system using a straight-through

CAT-5 cable to the networked environment and

interface to it from a remote computer. Figure A2

shows the proper way to interconnect the equip-

ment for a networked connection as well as the

pinout for a straight-thru CAT-5 cable.

REQUIRED EQUIPMENT

Cat-5 Straight-thru Cable

Laptop Computer with a network interface card

installed. In addition, the JAVA run-time environ-

ment version 1.6.0 or later, and a web browser

such as Internet Explorer must also be installed on

the laptop.

PROCEDURE

Before a networked connection can be established,

the booster LAN Port must be changed to an IP

address that’s compatible with your network. If you

are unsure how to determine this address check

with your IT support personnel. To connect the

booster LAN port to a networked environment and

access the web page interface, perform the follow-

ing steps;

1) Change the boosters LAN port IP address. To

do this, direct connect your laptop to the

booster as discussed in the earlier section of

this appendix titled “Direct Connection” and fol-

low steps 1 through 4.

2) Launch the configuration Applet in your web

browser.

3) Click the “Admin” tab at the top of the interface

display screen.

4) To be safe, take note of the settings currently

displayed.

5) Select the “User Static IP” radio button.

6) Enter the following settings provided by your

network administrator;

A) IP Address

B) Subnet Mask

C) Gateway Address

7) Click the “Submit” button to apply the changes.

8) Once the changes have been successfully

applied close your web browser.

9) Launch the configuration Applet in your web

browser using the newly entered IP address.

TX RX Systems Inc. Manual 7-9485-1.9.1 10/26/17 Page 31

When you initially direct connect your laptop ser-

vice computer to the booster it will be necessary to

change the computers IP address. The procedure

for doing this varies depending upon your operat-

ing system. As an example, this appendix illus-

trates how to make the change using the Microsoft

XP operating system. The procedure for other

operating systems will vary slightly from this exam-

ple. Consult with your IT support personnel if

needed. To change the IP address (assuming the

Microsoft XP operating system is being used) per-

form the following in a step-by-step fashion;

1) Select “Start” from the status menu.

2) Single click the “Control Panel” choice from the

“Start” pop-up menu as shown in Figure B1.

3) From the “Control Panel” icon selections double

click on the “Network Connections” icon. Refer

to Figure B2.

4) When the “Network Connections” folder opens

double click on the “Local Area Connection”

icon. See Figure B3.

5) The “Local Area Connection Status” box will

open. Single click the “Properties” tab as shown

in Figure B4. Note: If you do not have the cable

connected between the service computer and

the booster front panel the “Local Area Connec-

tion Status” box will not open. Instead proceed

to step 6.

6) The “Local Area Connection Properties” box will

open. Use the arrow buttons to scroll down the

list until the “Internet Protocol (TCP/IP)” choice

is highlighted as shown in Figure B5. Click the

“Properties” tab at the right-center of the box.

7) Select the “Use the following IP address” bub-

ble. Make sure the circle is filled-in. Refer to

Figure B6.

8) Enter the new IP address and subnet mask val-

ues as shown in Figure B7. To interface your

computer to the signal booster use an IP

address of “192.168.1.2” and a subnet mask of

“ 255.255.255.0”.

9) Click on the “OK” tab to initiate the changes.

This completes the procedure. Close any open

boxes.
