1. REGULATORY AND SAFETY INFORMATION
1.1 MAXIMUM PERMISSIBLE EXPOSURE LIMITS
DO NOT TRANSMIT with this base station and antenna when persons are within the MAXIMUM
PERMISSIBLE EXPOSURE (MPE) Radius of the antenna. The MPE Radius is the minimum distance
from the antenna axis that ALL persons should maintain in order to avoid RF exposure higher than the
allowable MPE level set by the FCC.
WARNING
FAILURE TO OBSERVE THESE LIMITS MAY ALLOW ALL PERSONS WITHIN
THE MPE RADIUS TO EXPERIENCE RF RADIATION ABSORPTION, WHICH
EXCEEDS THE FCC MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMIT. IT IS
THE RESPONSIBILITY OF THE BASE STATION OPERATOR TO ENSURE THAT
THE MAXIMUM PERMISSIBLE EXPOSURE LIMITS ARE OBSERVED AT ALL
TIMES DURING BASE STATION TRANSMISSION. THE BASE STATION
OPERATOR IS TO ENSURE THAT NO BYSTANDERS COME WITHIN THE RADIUS
OF THE MAXIMUM PERMISSIBLE EXPOSURE LIMITS SHOWN BELOW.
1.2 DETERMINING MPE RADIUS
THE MAXIMUM PERMISSIBLE EXPOSURE RADIUS HAS BEEN ESTIMATED TO BE A
RADIUS OF 24 feet maximum assuming the highest Effective Radiated Power (ERP) allowable under
FCC rules for base station Antenna installations. This estimate is made assuming maximum allowable
ERP level by the FCC and 100 percent duty cycle. The MPE calculations were made assuming worst
case in each band with respect to frequency, ERP and Limit. The maximum allowable ERP was
determined from the applicable part 90 rules regarding power limitation (90.205, 90.309, 90.635). The
limit used was for uncontrolled exposure. The formula used was derived from OET 65, section 2,
equation 4.
1.3 SAFETY TRAINING INFORMATION
WARNING
YOUR M/A-COM MASTR III BASE STATION GENERATES RF
ELECTROMAGNETIC ENERGY DURING TRANSMIT MODE. THIS BASE
STATION IS DESIGNED FOR AND CLASSIFIED AS “OCCUPATIONAL USE ONLY”
MEANING IT MUST BE USED ONLY IN THE COURSE OF EMPLOYMENT BY
INDIVIDUALS AWARE OF THE HAZARDS AND THE WAYS TO MINIMIZE SUCH
HAZARDS. THIS BASE STATION IS NOT INTENDED FOR USE BY THE
“GENERAL POPULATION” IN AN UNCONTROLLED ENVIRONMENT. IT IS THE
RESPONSIBILITY OF THE BASE STATION OPERATOR TO ENSURE THAT THE
MAXIMUM PERMISSIBLE EXPOSURE LIMITS DETERMINED IN THE PREVIOUS
SECTION ARE OBSERVED AT ALL TIMES DURING TRANSMISSION. THE BASE
STATION OPERATOR IS TO ENSURE THAT NO BYSTANDERS COME WITHIN
THE RADIUS OF THE MAXIMUM PERMISSIBLE EXPOSURE LIMITS.

5. SITE PREPARATION
5.1 INTRODUCTION
Before you install a MASTR III ADC Base Station, you need to prepare your site. Consider the
installation of the antenna system, space requirements, and weight. These issues are addressed in this
chapter.
This chapter is divided into the following sub-sections:
• Facility Preparation
• Power Installation
• Inter-Site Communication
• Protective Grounding
• Antenna System
• Power Up Sequence
5.2 FACILITY PREPARATION
This section provides information for preparing the facility prior to receiving or installing the MASTR III
ADC Base Station equipment.
5.2.1 Floor Plan
When creating the floor plan for cabinet placement, ensure consideration is given to safety, lighting, fire
suppression systems, access to other equipment and storage facilities in the room, etc.
5.2.2 Equipment Cabinet Placement
Direct access (for antenna cables and personnel) between the tower and the equipment room is necessary
for installation purposes).
The equipment cabinet you plan to install should be in an area that is:
• A dedicated equipment room or closet, wired in accordance with local electrical codes
• Large enough to allow easy access for service and maintenance
• Free of dust, smoke, and electrostatic discharge
• Properly ventilated
• Well lighted
NOTE
The recommended aisle spacing is 29.5 in. (750 mm).
MM102554V1 R1A
20
5.2.3 Ceiling Requirements
Consider the following ceiling requirements before you install the equipment cabinet:
• The ceiling should be clear of obstructions such as beams, heating and air conditioning ducts, water
pipes, and lights.
• The ceiling should not have sprinklers; however, appropriate fire protection devices should be
available.
5.2.4 Size and Weight Considerations
Before you install the equipment at your site, make sure that the equipment room can accommodate the
size and weight of the cabinet and the MASTR III ADC Base Station. To determine the total weight, add
the weight of the radio system (about 150 lbs, 68 kg for each radio system), and the weight of the rack.
Typical equipment size and weight is listed in the Specifications section. For the specific weight of
individual units or optional equipment, you should refer to the applicable maintenance manuals or product
Data Sheets.
5.2.5 Operating Environment
The equipment room or area where the MASTR III ADC Base Station is installed must meet the
environmental conditions listed in the Station Specifications section of this manual. In addition, the site
grounding must conform to the requirements of the Standards for Site Grounding and Protection manual
AE/LZT 123 4618/1.
Although the temperature requirements for individual components may be broader, when several units are
assembled together in a cabinet more heat is generated. Because of this condition, the ambient room
temperature outside the cabinet must be lowered to ensure the temperature inside the cabinet does not
exceed the limits for the equipment.
5.3 POWER INSTALLATION
In all cases where the customer provides a single AC supply input to a site, for AC or DC systems, the
input must be protected with a Joselyn AC protector, or equivalent. The AC Protector is installed after
the disconnect switch and must be connected to the external ground system.
If the AC supply is provided from wall outlets, the fuse panel breaker for the room must be sized for the
load of the proposed equipment that is to be installed in the site.
5.3.1 Existing Input Power
If the site already has an existing input power source, then the installers and a certified electrician should
ensure the power meets site requirements and is equipped with the necessary breakers to conform to both
design and local regulatory standards.
If the site input power source does not meet the site requirements or is not equipped with the necessary
breakers to conform to both design and local regulatory standards, refer the matter to the Site Manager.
MM102554V1 R1A
21
5.3.2 AC Distribution
If the site requires an AC distribution system to be installed, ensure it installed by qualified installers in
agreement with the customer. The Applications Engineer will provide the Site Manager with drawings
containing the installation requirements.
Ensure the input supply is isolated and power is not applied until the installation is complete.
5.3.3 Generator System
If the system already has a backup generator system providing backup supply to the site, inspect and test
the generator as defined in the equipment manuals.
Sites equipped with generator systems will use a manual or an automatic transfer switch system. Inspect
the customer system to ensure that it is fitted with the appropriate transfer switch system. This is to be
inspected and tested as defined in the equipment manuals.
If a new generator system is being installed, ensure it is installed by qualified generator installers in
agreement with the customer. When installing generator system remote controls, ensure that the installer
thoroughly understands the application and necessary generator connections. The Applications Engineer
will provide the Site Manager with drawings containing the installation requirements.
5.3.3.1 Manual Transfer Switch
If a Manual Transfer Switch is to be installed, the same team who installed the generator should install the
transfer switch. If this is an additional or new feature, the system is to be modified by qualified engineers
in agreement with the customer. The Applications Engineer will provide the Site Manager with drawings
containing the installation requirements.
5.3.3.2 Automatic Transfer Switch
If an Automatic Transfer Switch is to be installed, the same team who installed the generator should
install the transfer switch. If this is an additional or new feature, the system is to be modified by qualified
engineers in agreement with the customer. The Applications Engineer will provide the Site Manager with
drawings containing the installation requirements.
5.3.4 AC-DC Supply
If the system already has an AC-DC conversion system that meets the system requirements, then inspect
and test the system as defined in the equipment manuals.
If the site requires an AC-DC conversion system to be installed, this is to be performed by qualified
installers in agreement with the customer. The Applications Engineer will provide the Site Manager with
drawings containing the installation requirements.
The system will normally include input circuit breakers, a rectifier stage, converters and individual output
circuit breakers. These components will have their voltage and/or current specified on the site design
drawings. Ensure that input supply is isolated and not re-apply power until installation is complete.
MM102554V1 R1A
22
5.3.5 Battery Backup
A Battery backup system is normally installed to ensure smooth supply voltages during normal operation
or in the event of an input power failure.
If the site already has a battery backup system that meets the system’s requirements, then inspect and test
as defined in the equipment manuals.
The battery backup system will normally be a battery cell system. The backup battery system capacity
should be sufficient to provide the radio system with the desired voltage for a specified time. This should
also include power needed for the inverter equipment, input and output breakers, and either manual or
automatic switches to switch the system into circuit. The installation requirements will be in the site
design drawings agreed to by the customer and Application Engineer.
5.3.6 UPS
An Uninterruptible Power Supply (UPS) system may be an alternative to other backup supply options. It
may comprise some or all of the following components:
• Input supply and protection
• Various DC outputs (additional equipment that is required)
• Output protection
• Battery backup
• Bypass switch
• Automatic switch-over to generator
If the site already has an UPS system that meets the system requirements, then inspect and test the UPS as
defined in the equipment manuals.
If the site requires an UPS system to be installed, ensure the installation is made by a qualified installer in
agreement with the customer. The Applications Engineer will provide the Site Manager with drawings
containing the installation requirements.
5.3.7 Electrical Power
5.3.7.1 AC Power
Each MASTR III cabinet is equipped with its own AC power cord. Each of these power cords should be
connected to a separate circuit breaker. The following circuit breakers are recommended.
• 115 VAC (60 Hz) - a 20-amp circuit breaker for each power cord.
• 230 VAC (50 Hz) - a 15-amp circuit breaker for each power cord.
Receptacles must be installed within reach of the power cords and should be individually fused. They
may be installed on the wall behind the cabinets, in the floor under the cabinets, on the cable ladder above
the cabinets, or in the cabinet top cable ducts. The power cords must not be installed such that they cause
a hazard to persons in the site.
AC Power Installation must conform to local Installation Regulations.
MM102554V1 R1A
23
5.3.7.2 DC Power
When required, DC power options are available, but will be customized for the particular system. The
power supplies will be omitted from the cabinets and replaced by a fused DC panel. In this case, power
must be supplied to the repeaters from an external 13.8 or 24 VDC power source through a separate 30-
amp circuit breaker for each repeater.
The supply system will normally consist of an AC to DC converter, a Circuit Breaker Panel and various
DC-DC Converters sized for the equipment. DC feeds to the equipment that will be direct from the circuit
breaker panel.
5.3.7.3 Generators
Some systems, predominately remote sites, will require emergency generators with automatic switchover
systems. The generators must be connected to the external site grounding system and should be located
external to the equipment room.
Automatic switchover systems must be disabled during installation.
5.3.7.4 Battery Backup
Some systems will require a battery backup connected to the supply system in case of input power failure.
The battery bank should be located either separate from the equipment room or within the room but at a
point furthest from the entrance. It should have a separate fume extraction system or should be located
below the air extraction system for the site.
5.4 INTER-SITE COMMUNICATIONS
There are various types of Inter-Site Communication Systems, which require interfaces to be pre-installed
within the site. These interfaces will be the agreed demarcation points to which the Customer, Sub-
Contractor and system installer will make connections.
There are three types of inter-site connections:
• Hardwire Installation
Direct Connection
• Leased Line
Leased or Dedicated Telephone Line
• T1 or E1
Leased T1 or E1
Microwave
Fiber Optic Cable
5.4.1 Hardwire Installation
When the media specified is to be Hardwire, that is point-to-point wiring on-site, the following
specifications apply:
MM102554V1 R1A
24
• Audio: 2-wire or 4-wire shielded cable; screen connected to site ground system and cable core is to be
solid in order that it may be punched-down.
• Data: Shielded twisted pair, shield connected to site ground system and cable core is to be solid in
order that it may be punched-down.
5.4.2 Leased Telephone Lines
When the media specified is to be Leased-Line via the local telephone company, request a 4-Wire 43202
Type 5 Data-Grade line from the local or regional telephone carrier. If using an equivalent line (old
specification is 3002 Data Grade), it must meet the following specifications:
• Frequency response:
1000 Hz Reference
500 - 2400 Hz -1 to +3 dB
300 - 2700 Hz -2 to +6 dB
• Max Frequency Error = ±5 Hz
• Max Net Loss = 16 dB
• Max Group Delay (800-2400Hz) = 2000µS
• Min S/N Ratio = 24 dB
The Telephone Company or customer will provide a point of interface for the telephone system within the
site known as the Demarcation Point. The installer will make necessary connections between the
Demarcation Point and the equipment
5.4.3 T1 or E1 Links
A T1 or E1 link may be leased from the Local or Regional Telephone Carrier. The physical link may be
via a Microwave System or via Fiber Optic cable. The Microwave or Fiber Optic system may also be
provided by the customer or sub-contracted from an alternate provider.
5.4.3.1 Leased T1/E1
If the link is Leased-Line T1 or E1, the carrier may provide the Multiplex (Mux) equipment and Channel
Service Unit (CSU). If so, they will connect to an agreed Demarcation Point (Punchblock) and collect the
data and modem audio as appropriate. If they do not provide the Mux or CSU, a Mux and CSU will be
provided and the demarcation point will be the appropriate T1/E1 interface on the Mux or CSU.
5.4.3.2 Microwave
The Microwave system may be provided by the Customer, M/A-COM, or a Sub-Contractor. Whichever
is the case, the Inter-Site Communications System should be in place prior to equipment installation and
the system provided will have a Demarcation Point to which the installer will connect the Inter-Site
Communications. This may be Punchblocks or the input connection to the multiplexer and the length of
the cross-connect cabling must be calculated to allow for the agreed location of the interface.
It is normal for the microwave radio to be close to its antenna and, in some installations, this may mean
some distance between radio and multiplexer. If the distance between radio and multiplex equipment is
excessive, consideration must be given to type of cable used for the connection, cable shield/ground,
MM102554V1 R1A
25
grounding through in-building cable routes, etc. This subject is to be discussed with microwave provider
and must conform to local installation regulations.
5.4.3.3 Fiber Optic
It is a requirement that the demarcation point for fiber optic cable is the fiber optic interface on the
multiplexer. If the multiplexer is not equipped with such an interface, a fiber optic line driver will be
provided and will be the point to which the cable is to be connected.
All other considerations are as for Microwave.
5.5 PROTECTIVE GROUNDING
For information on protective grounding outside the equipment room and general information for internal
grounding refer to the Site Grounding and Lightning Protection Standard manual AE/LZT123 4618/1.
However, a general rule for the external grounding system is that the resistance to ground should be five
(5) ohms or less, as measured with a Biddle DET2/2 Megger or equivalent, per IEEE STD 81-1983 or
local equivalent.
All equipment that is within the site must be connected to an internal halo ground of No. 2 AWG copper
wire six (6) inches below the ceiling. This interior halo ground must be connected to the external ground
system at each corner, using separate No. 2 AWG copper wires. The halo may be mounted on the cable
ladder, in the ducting or beneath the false floor.
All metal (electrically conductive) objects within the equipment room must be grounded. These objects
are divided into the following three (3) groups.
• Room Fixtures
• Power Supply
• RF equipment
All metallic fixtures and room parts, such as doorframes, sheet metal, ventilation louvers, air conditioning
units, light fixtures, etc., should be connected to the internal halo ground.
In addition to all other AC power protection, the AC power must be equipped with a Jocelyn AC
protector, or equivalent, placed immediately after the main disconnect switch. This protector must be
connected to the external ground system using a separate No. 2 AWG copper wire.
All equipment cabinets, cable trays, and protectors for cables connecting to this equipment must be
connected to a single grounding plate or bulkhead panel mounted on the wall where the antenna cables
enter the equipment room. This grounding plate must be connected to the external ground system using
two (2), two-inch wide copper strapping, or equivalent. A separate No. 6 AWG copper wire must be used
for each cabinet, each cable tray/ladder, and each group of cable protectors.
A few general rules of thumb are as follows:
• Make ground wires as short as possible and direct as possible - avoid bends if possible - absolutely no
bends with a radius of less than eight (8) inches.
• Surface area of ground wires is more important than cross sectional area.
• All connections must be clean, free of non-conductive coatings, and be coated with an anti-oxidant.
MM102554V1 R1A

5.6 ANTENNA SYSTEM
This section covers installing the antenna system, including RF cables from the antenna to the equipment
room wall feed through connector.
NOTE
Refer to LBI-39185 for Tower Requirements and General Specifications.
Crews trained and equipped for working on antenna towers generally install antenna systems. As a result,
this manual assumes crews with the specialized equipment and skills required for working on towers and
installing the antenna cables will install the Antenna Systems. However, it may be necessary for the
system installer to provide information and directions to the crew installing the antenna system and to
verify proper installation.
5.6.1 Antenna Mounting
The antennas must be installed on the tower in such a way as to ensure that there is at least 25 dB of
separation between the TX and RX antennas. This is necessary to avoid interference in the receivers
caused by the transmitters. An isolation of greater than 25 dB is easily obtained by placing one antenna
directly above the other on the tower (minimum 10-foot separation).
MM102554V1 R1A
27
Figure 5-1: Antenna System Requirements
5.6.2 Transmission Lines
When installing the transmissions lines, refer to the block diagram for UHF and 800 MHz Antenna
Systems contained in LBI- 38983.
5.6.2.1 Length
The length of the main coaxial cable for each antenna should be planned as a continuous run with no
connectors or splices between the antenna and the equipment room. Each cable includes a 50-foot
allowance for the distance from the bottom of the tower to the equipment room. Smaller diameter, more
flexible coaxial cables are used at both ends of the main coaxial cable to facilitate installation.
MM102554V1 R1A
28
5.6.2.2 Minimum Bending Radius
Always adhere to the minimum bending requirements provided by the manufacturer. For Andrew
Products, the values are:
CABLE SIZE BENDING RADIUS
1/4-inch 1-inch (25 mm)
1/2-inch 1.25-inch (32 mm)
7/8-inch 10-inches (250 mm)
1 5/8-inch 20-inches (510 mm)
5.6.2.3 Hoisting Grips
Hoisting grips provide the means to attach a lifting mechanism to the coaxial cable without damaging the
cable. Each hoisting grip is capable of safely lifting 200 feet of cable without causing damage.
Therefore, one hoisting grip is required for every 200-foot section of cable. The grips may be left
attached to the cable after the cable installation is completed.
Some situations may require more hoisting grips, such as:
• When installing cables on a tower mounted on top of another structure.
• When installing a cable whose length is greater than the height of the tower.
In these situations, additional hoisting grips should be ordered.
5.6.2.4 Hangers and Adapters
Coaxial cables on the tower should be secured at intervals of 3-5 feet (maximum).
Securing 7/8-inch and 1-5/8-inch diameter coaxial cables is accomplished by using either hangers or
hanger-adapter combinations. The hangers secure the cables to the tower structure by using prepunched
holes or attachment adapters.
• When the tower structure is prepunched with 3/4-inch holes, snap-in hangers are used (preferred
method).
• When the tower is prepunched with 3/8-inch holes, the hanger is secured by a 3/8-inch bolt.
For towers without prepunched holes, the hangers are attached with adapters. The type of adapter
depends on the type of tower structure. Adapters are available for either angle tower members or round
tower members.
Adapters for each antenna system are selected when ordering the system. If the coaxial cable must be
attached to a structure that is not compatible with any of the above hangers or adapters, then additional
materials or other special considerations may be required
To secure 1/4-inch or 1/2-inch vertical or horizontal coaxial cables of any size, use nylon cable ties.
MM102554V1 R1A
29
5.6.2.5 Weatherproofing
A kit of weatherproof tape is provided to protect coaxial connectors from the outside elements. One roll
of tape is sufficient to weatherproof four exposed outside connector joints.
5.7 QUALITY AUDIT
5.7.1 Antenna System
After the Antenna System is installed, it should be inspected before the installers leave. A checklist of
tasks performed on the antenna system is provided in section 12.3. Be sure to complete this visual
inspection before the installers leave, so any obvious errors can be corrected.
Using field glasses, if necessary, view the Antenna System from various positions on the ground. Using
copies of the Antenna System Installation Checklist 12.3, fill out a checklist for each antenna as you go
through the following inspection procedure. This will provide a record of the inspection, and of some
antenna information for future reference.
• Record the make of antenna.
• Record the type of antenna (omni or directional).
• Record the design gain of the antenna.
• If the antenna is directional, record the bearing of the main lobe. If it is omni, write "Omni" in the
data entry line.
• Record the height of the antenna above ground.
• Confirm that cable-hoisting grips were installed as required to prevent damage to the coaxial cable.
Hoisting grips should have been installed at the antenna end of the cable plus one for each 200 feet of
cable length.
• Confirm the cable is secured to the tower at intervals, which do not exceed 3 feet.
• Confirm the cable is grounded at the top of the tower.
• Confirm the cable is grounded at the point where it leaves the tower.
• Confirm the cable is grounded at the point where it enters the building.
• Confirm the coaxial cable run looks OK. The cable must be tight (nothing to flap in the breeze), have
no kinks, is one continuous run (no connectors or splices), and not exceed the minimum-bending
radius on any bend.
• Confirm the cable feed through is properly installed where the cable enters the building.
• Confirm the coaxial connectors have been properly weather sealed with tape.
• Confirm the cable entrance to the building has been properly weather sealed.
MM102554V1 R1A

5.7.2 Electrical System
If the electrical supply system has been installed by other than the company, it must be inspected to
ensure that it is safe and complies with both local regulations and the requirements of the site. Complete
the Power System Installation Checklist found in section 12.5, as required.
• Confirm that the supply system is rated to handle the full operating load of the equipment.
• Confirm that all outputs to which the site equipment will be connected have suitably rated breakers
installed.
• Confirm that electrical cabling to the equipment is correctly rated, installed and meets local
regulations.
• Confirm that the system is correctly grounded.
• Confirm that cables, bus bars and associated equipment are not a hazard to installers or maintenance
teams.
• Confirm that manuals for the supply system have been provided at the site.

6. EQUIPMENT INSTALLATION
6.1 INTRODUCTION
NOTE
AC power adequate to meet system requirements, environmental control, civil works and
site preparation, and digital or voice grade phone lines must be available at the site prior
to installation.
WARNING
DO NOT apply power at this time!
During installation, all circuit breakers must be left in the OPEN position. Make sure all
equipment circuit breakers are in the OPEN position.
To prevent damage to equipment, ensure power is not accidentally applied at this time.
This chapter is divided into the following sub-sections:
• Unpacking the Equipment
• Equipment Installation
• Interior RF Cabling
• Connecting Electrical Power
• Quality Audit
6.2 UNPACKING EQUIPMENT
Station equipment is generally packed in one of the following ways:
• Bolted vertically to a mini pallet approximately 36” deep x 32” wide, with a corrugated cardboard
cover held down with two plastic straps. This technique is generally used for domestic shipments.
The mini pallet adds approximately three inches to the overall cabinet height. The weight varies
according to the content, but generally runs from 300 pounds to 600 pounds.
• Crated vertically or horizontally. This technique is generally used for open-racked equipment and
overseas shipments of 69-inch and 83-inch cabinets. Crates may contain one or several cabinets or
racks, and the dimensions and weight will vary accordingly. If size and weight limits are required,
contact the factory for special packing instructions.
Cabinets packed on mini pallets can be moved with a hand-truck, crates may need a forklift or pallet jack,
depending on the size. Wrenches will be needed to unbolt the cabinets from the mini pallets, and a
crowbar and hammer will be useful in opening the crates. Do not leave packed or unpacked equipment
exposed to the weather.
Upon receipt of the station equipment, carefully examine each carton. If any packaging damage is
detected, note the damage on the Bill of Lading.
MM102554V1 R1A
32
Move the cartons as close as possible to their mounting location.
Carefully unpack the equipment and examine each item. If there is any damage to the equipment, contact
the carrier immediately and have their representative verify the damage. If you fail to report the shipping
damage immediately, you may forfeit any claim against the carrier.
When unpacking the equipment, check the contents against the packing list. Contact your M/A-COM
representative and the carrier if any discrepancies are noted.
Carefully open each cabinet and inspect the contents to ensure that enclosed equipment has not been
damaged during delivery. If damage has occurred, note details of the damage and, if necessary, contact
the carrier immediately and have their representative verify the damage. Contact your M/A-COM
representative if the damage is such that installation cannot proceed.
6.3 EQUIPMENT INSTALLATION
NOTE
Refer to AE/LZT 123 4618/1 for Site Grounding and Protection Standards.
NOTE
These procedures are for M/A-COM standard installations. If the system is non-
standard, installation procedures may differ. In this event, installers should consult with
M/A-COM.
• This section provides instructions for installing the RF Equipment and for running the necessary RF
cables to the equipment room wall TX and RX feed through connectors.
6.3.1 Mounting Vendor Supplied RF Equipment
RF Equipment used for interfacing the Antenna System to the Repeaters may be pre-racked by M/A-
COM or dropped shipped from the individual vendors directly to the customer. If the RF equipment is
supplied directly from the vendor, it will be necessary to install the equipment into the RF Equipment
Cabinet.
NOTE
The system is designed to use either a Tower Top Amplifier or a Receiver Filter. When a
Tower Top Amplifier is used, the Receiver Filter is not required.

1. Install the vendor supplied RF equipment into the RF Equipment cabinet.
2. Secure each component to the cabinet using standard mounting screws and clips that come as part of
the cabinet hardware kit.
3. Mount the Receive Surge Protector (IS-DC50LNZ-MA), if not previously installed, to the grounded
bulkhead panel, located at the wall feed through where the antenna system enters the building. Other
installers (refer to Surge Protector Diagrams in Figure 6-1 and Figure 6-2) should have already
installed this panel.
MM102554V1 R1A

4. Mount the transmit surge protector (IS-CT50LNZ-MA) to the grounded bulkhead panel, located at
the wall feed through where the antenna system enters the building. Installers should have already
installed this panel. (Refer to Surge Protector Diagrams in Figure 6-1 and Figure 6-2)
5. Install Top Cover (if cabinet).
6.3.2 Mounting Base Station Cabinet (Typical)
The following tools and materials are typically needed to fasten the cabinets to concrete floor (if installing
on wood flooring - do not use lead anchors):
• ½" x 2" Lag screws (4 per rack)
• 1/2" Flat washers (4 per cabinet/rack)
• Lead anchor for 1/2" lag screws (4 per rack)
• Measuring tape
• Heavy-duty marker (suitable for marking coarse concrete)
• Eye protection
• Ear protection
• Drill with masonry bit (see size marked on anchor)
• 1/4" x 24" Flexible plastic tubing (blow debris out of hole)
• Hammer (seat anchor in hole)
• Wrench (screw lag screw into anchor)
The following additional hardware is supplied with each optional open-rack. The hardware enables the
installer to fasten adjacent side rails together at the top and bottom:
• 3/8" x 1 1/2" Hex machine screws (2 per open-rack)
• 3/8" Hex nut (2 per open-rack)
• 3/8" Flat washers (4 per open-rack)
• 3/8" Lock washer (2 per open-rack)
The RF Equipment cabinet(s) should be located at a point nearest the RF Bulkhead, where the antenna
cables enter the building. This allows the antenna cable lengths to be minimized.
Position the cabinet(s) on the floor exactly where they are to be mounted. Allow one (1) meter (3 feet) of
free space in front of and behind each cabinet, to allow the cabinet doors to swing completely open. Also
allow one (1) meter (3 feet) of free space around at least one end of each row of cabinets, to get to the
back of the cabinets.
Mark the position of the mounting bolt holes on the floor using the four holes in the bottom of each
cabinet as a template. Move the cabinets, drill the holes in the floor for the screw anchors, seat the
anchors in the holes, reposition the cabinets, and fasten the cabinets down with lag screws (use a flat
washer under each lag screw head, to prevent damage to the cabinet).
MM102554V1 R1A

6.4 INTERIOR RF CABLING
Some RF coaxial cables may be pre-made and included with the system. However, most cables must be
custom made, on site, to the required length. Table 6-1 lists the cables and associated connectors, which
are typically fabricated at the site.
The coaxial cable and connectors are supplied in bulk. To cut the cable properly for easy connector
attachment, use an Andrew's "EASIAX" coaxial cable cutting tool (or equivalent).
NOTE
When installing the RF or power cables, refer to the Antenna System Block Diagrams in LBI-
38983 and the Application Assembly Diagrams in technical manual MM102556V1 for in
installation instructions.
6.4.1 Cable Routing
If cabinet-top cable ducts are supplied, install per LBI-38875 using the hardware provided. However,
leave the duct covers off until the site wiring is complete. These cable ducts are not available for open-
type equipment racks.
Larger systems should make use of cable ladders for ease of installation and maintenance. It is preferable
that dual ladders be used for large systems such that audio and data may occupy one level of the ladder
and RF and power occupy the other. If dual systems are not available, ensure maximum separation
between Audio/Data runs and RF/Power runs.
Install as shown on the site plans and install all grounding leads across ladder section connections.
6.4.2 Install RF Cables
Assemble and install the RF coaxial cables. Be careful not to exceed minimum bend radius (refer to Site
Preparation - Antenna System for specifications).
Refer to the Antenna Systems Assembly Manual LBI-38983 and applicable vendor manuals for TX and
RX connection points. (For specially engineered systems, refer to the Site Antenna System drawings for
the site.)
Use cable ties to secure the coaxial cables to the back rails of the cabinets. Ensure cables do not impede
access to the internal equipment and the installation appears neat and orderly. Exercise caution and
ensure cables are routed away from the sharp ends of mounting screws (on the backside of the equipment
rails). Allow room for equipment mounting screws to be removed and re-installed without damaging the
cables.
NOTE
If overhead cable ladders are used, ensure the RF cable are of sufficient length to run from
point A to point B via the cable ladder. Do not loosely ‘drape’ cables on the top of cable
ladders or racks.
Begin the cable installation by installing receiver cables first. Then complete the installation by installing
the transmitter cables.

7. DC AND TONE REMOTE CONTROL INSTALLATION
This chapter provides information for connecting a DC or Tone Remote Control system to the base
station.
The DC Current or Tone Signaling Remote controllers available from M/A-COM are full-function
controllers used to operate the base station from a remote location. The DC Current Remote Controller
can control and display up to four channels, and the Tone Remote Controller can control and display up
to eight channels. Parallel controllers can receive indications of transmit and remote selections. In
addition, 10 or more dispatch points (remote controllers) can operate a single base station.
Wiring between a remote controller and the base station is usually made using direct wire lines or leased
telephone lines. This wiring may also be used in conjunction with a Multiplex or Microwave system.
7.1 DC REMOTE INSTALLATION
The MASTR III Conventional ADC Base Station can be remotely controlled by DC control currents. A
DC remote control unit can initiate a transmission, listen to received audio, and select or deselect certain
base station functions. Control current signaling from a DC remote control unit consists of applying
different current levels on a wire pair having DC continuity. The six control current levels used for
controlling the base station are:
• -11 milliamperes • 0 milliamperes
• -6 milliamperes • +6 milliamperes
• -2.5 milliamperes • +11 milliamperes
The following station functions can be controlled by using control currents:
• Repeater Disable
• Channel Guard Monitor
• Transmit Frequency Selection
• Receive Frequency Selection
• Scan
• Receiver Selection (Auxiliary Receiver selection)
Table 7-1 is a list of DC Control Currents and their corresponding functions.
7.1.1 Wiring Methods for DC Remote
DC Remote Control units can be connected to the base station in one of four connection schemes. The
choice of which installation method should be used is based on the cost, availability, and performance as
compared to controller’s operating environment.
Table 7-2 provides a description of the four methods and gives some of the advantages and disadvantages
of each method. After the table, installation procedures are available for each method. The procedures
contain detailed wiring instructions. These instructions assume a M/A-COM DC Remote Control unit is
being connected to the base station.

METHOD DESCRIPTION ADVANTAGES OR
DISADVANTAGES
1 Single metallic pair (the control
currents are simplexed to line, a two
wire cable is required).
This is the most economical method. It is
dependable where earth ground currents may be
large or good earth grounds cannot be obtained.
The keying clicks will be heard on paralleled
remotes.
2 Single metallic pair (the control
currents are simplexed line to earth
ground, a two wire cable is
required).
This method is also economical. It minimizes
keying clicks in paralleled remotes. Large ground
currents may result in interference with control
functions if remotes are located near sub-stations.
3 Two wire pairs needed. One is a
voice grade pair for bidirectional
audio and the other is a metallic pair
used for control current.
Provides excellent performance by eliminating
keying clicks and providing no path for ground
loop current. However, it does require two wire
pairs.
4 Two wire pairs needed. One is a
voice grade pair for receive audio.
The second is a metallic pair for
transmit audio and control Currents.
Provides full duplex operation in which the
remote can receive and transmit at the same time.
However, it does require two wire pairs.

7.2 E & M SIGNALING
E & M lead signaling systems derive their name from certain historical designations of the signaling leads
on circuit drawings. An “M” lead is associated with the transMit function or Mouth, while the “E” lead
is associated with the recEive function or Ear. In some two-way radio systems with remote control, E &
M Signaling may be the only type of control offered by the available carrier circuits.
Generally, both 4-Wire Audio and E & M Signaling options are used to interface between the radio and
carrier systems. However, 2-Wire Audio can be used in the two-way radio portion of the control system
if hybrids are installed to provide transition between the 2-Wire and 4-Wire connections. Usually the E &
M Signaling is separated from the audio (separate line) in both 2-Wire and 4-Wire installations.
7.2.1 Standard (Type II) E & M Signaling
The Standard or Type II E & M (+48 V) signaling method uses four wires for signaling, the “E” pair at
the Remote Control Console and the “M” pair at the base station. This configuration uses four wires for
audio. One voice grade pair is used for TX audio and the other pair is used for RX audio. This is
illustrated in Figure 7-5, which also shows the interface between a two-way radio system and a
multiplex/microwave system.
At the console a regulated -48 VDC output (or -24 VDC with minor modifications) is applied to the "M"
lead when the TRANSMIT switch is pressed. This -48 VDC activates a tone encoder (usually 3825 Hz)
in the multiplex rack. The tone encoder modulates the carrier frequency, which is transmitted over the
microwave link.
At the station end of the microwave link, the signal is demodulated and the 3825 Hz tone operates a tone
decoder in the multiplex rack. The output of the decoder results in a contact closure, which applies +48
VDC (or +24 VDC) to the DC control lines on T/R Shelf. The DC Current Detection Circuit detects the
presence of the +48 V signaling as a +11mA current. The station then executes a “Channel 1 – Remote
PTT” which then keys the transmitter and routes the audio from the Line Input to the transmitter.
7.2.1.1 Installation
1. Connect the E & M control lines to TB101 pins 1 and 6.
2. Connect the remote control transmit pair (which modulates the transmitter) to TB101-2 and -5.
3. Connect the remote control receive pair (which listens to the receiver) to TB101-3 and TB101-4.
4. Remove jumpers from J104 and J105 on the Interface Board

Figure 7-5: Typical E & M Signaling Application
7.2.2 Type 1 E & M Signaling
E & M Type 1 signaling uses two leads, E and M, which share a common ground path. Type 1 E & M
signaling was originally designed for use with electromechanical switching systems and is not
recommended for use in electronic systems due to the noise induced by the ground path.
Type 1 E & M signaling keys the station remotely by using a contact closure to ground. When this option
is selected, control is exercised by applying a ground to P110 pin 1 (Repeater Hot Standby) on the station
Interface Board or by applying a ground to P5 Pin 16 on the station backplane. This causes the station to
execute a “Channel 1 – Remote PTT” which routes the audio from the Line Input to the transmitter.
7.3 TONE REMOTE INSTALLATION
In contrast with DC systems, where audio level setting is not as critical, it is important that levels in tone
applications be set properly. Failure to do so results in the control function not working properly. For
example, after the installation when the user has gained a little experience, the user may find that they are
not always picking up the function selected. A little extra time spent at the installation will save many
problems of this type later.
This equipment is designed so that the tone control sequence consists of two or three parts. The first part
is the “Secur-it” tone (2175 Hz), which is sent at the highest level for approximately 125 milliseconds.
This is followed by the “Function” tone which is sent at a level 10 dB lower for approximately 40 ms. In
the case of a transmit function, the “Function” tone is followed by 2175 Hz “Hold” tone at a level 30 dB
down from the “Secur-it” tone burst (therefore, it is 20 dB down from the “Function” tone burst). This
tone continues for the duration of the transmit function. The average voice (0 VU) is sent at the same
level as the “Function” tone, therefore, the test tone for the voice is sent at the same level as the “Secur-
it” tone.

Figure 7-6: Tone Control Sequence
The “Secur-it” tone must arrive at the base station at no less than -20 dBm. The transmit “Hold” tone
must arrive at the base station at no less than -50 dBm. The test tone for the voice must arrive at the base
station at no less than -20 dBm. Therefore, the limits of system operation are usually established by only
three things:
1. The maximum level at 2175 Hz that the phone company will allow to be sent from the most distant
point in the system. Normally this will not be higher than 0 dBm. In some cases, it can even be less,
or on rare occasions, it can be +5 or +10 dBm.
2. The loss of the circuit at 2175 Hz. Do not forget the long-term variation of up to 4 dB more.
3. The requirement that the “Secur-it” burst must arrive at the base station at no less than -20 dBm.
Normally, most systems will not crowd these limits. However, if the result is a few dB short, consider
adding C-1 conditioning (at an added cost). Resist the natural desire to just turn up the tone sending level
as this will cause improper system operation.
Increasing the level will cause the “Secur-it” tone burst to go into limiting in the phone company
equipment. The limited tone causes the “Secur-it” tone filter in the base station to ring. This will result
in picking up or dropping out functions, which were not selected. NEVER allow the “Secur-it” tone to be
in limiting.
There is an easy way to check and see if the “Secur-it” tone is in limiting. With the phone lines
connected to the equipment at both ends, connect an AC voltmeter across the phone line at the base
station. Arrange to send a burst of “Secur-it” tone long enough to measure the incoming level on the AC
voltmeter. Then arrange to send a burst of 1950 Hz “Function” tone long enough to measure the
incoming level on the AC voltmeter. If the 1950 Hz tone does not arrive 10 dB (1 dB) less than the
“Secur-it” tone, then the “Secur-it” tone is in limiting. It will become necessary to lower the sending
level at the remote controller until it is below limiting.
MM102554V1 R1A
48
If the audio is high enough to cause the telephone equipment to go into limiting, it will cause amplitude
distortion. On a high loss line, the amplitude distortion will cause the “Hold” tone (2175 Hz) to vary and
the transmitter to drop out.
On remote systems using tone control, care must be used when connecting two telephone lines in tandem.
For example, for a base station and two remotes, a phone line is ordered to connect the station to the first
remote, and a second line to connect the second remote to the first remote. The loss of each line is now
added together and the tones from the second remote cannot operate the base station. The installer can
either specify a low loss on each line, or run each line directly to the base station.
A check with the phone company can determine which approach is the least expensive over a period of
time; i.e., an analysis of non-recurring costs versus recurring costs over the expected length of time the
circuit will be used.
7.3.1 Voting System Considerations
A voting system uses a continuous 1950 Hz tone on the telephone line when the receiver is squelched.
This voting tone is normally sent from the station to the voting selector 3 dB lower than the 1000 Hz test
tone level. Most telephone lines have a frequency response, which attenuates the 1950 Hz tone with
respect to a 1000 Hz test tone; therefore, care should be taken to ensure that the correct levels are received
at the voting selector.
If the telephone company will not allow a continuous tone as high as -8 dBm to be sent, then a lower loss
circuit should be requested or C-1 conditioning added.
When ordering phone lines for a voting system, if possible, all lines should be of the same type. Different
telephone line responses will cause the voter to prefer one signal to others.
It is improper system design to have the received signal selection biased by a “poorer” telephone circuit.
Many telephone companies will add pads to build out the lines. If this is considered when the lines are
ordered, it should not be difficult to build all of the lines out to have the same frequency response.
A tone remote control unit can initiate a transmission, listen to received audio, and select or deselect base
station functions. Functions selected by the different available tones can be programmed so that a 1450
Hz “Function” tone, for example, can be used for different functions.
Signaling from a tone remote control unit consists of a high level “Secur-it” tone, followed by the
appropriate medium level “Function” tone (as well as a “Hold” tone if the transmitter is keyed). The
tone control sequence is shown in Figure 7-6.
The “Secur-it” tone is a +10 dB, 2175 Hz tone that is present for 125 milliseconds. The “Secur-it” tone
is followed by a 40 millisecond, 0 dB “Function” tone. The “Function” tone can be followed by a -20
dB, 2175 Hz “Hold” tone if PTT is selected. The “Hold” tone is present as long as the PTT is pressed.
7.3.2 Function Tones
The frequency of the “Function” tone determines the function selected by a tone remote control unit.
“Function” tones range from 1050 Hz to 2050 Hz, and are spaced 100 Hz apart.
The following station functions can be controlled by tone signaling from a remote control unit:
• Repeater Enable (disable)

• Channel Guard Decode Enable (disable)
• Channel Guard Monitor
• Transmit Frequency Selection

METHOD DESCRIPTION ADVANTAGES OR
DISADVANTAGES
1 Standard two-wire configuration.
Single voice grade pair used for both
control and audio frequencies.
This is the most economical method and simplest to
install. The cost varies depending on local service.
2 Standard four-wire configuration.
One voice grade pair is used for TX
audio and the other pair is used for
RX audio.
This method is also economical. It minimizes
keying clicks in paralleled remotes. Large ground
currents may result in interference with control
functions if remotes are located near sub-stations.

7.5 SQUELCH OPERATED RELAY OPTION (SXSU3D)
This section provides additional information for installing the Squelch Operated Relay (SOR) option
SXSU3S. The option kit includes the following items:
• K3, SOR – 19B235003P2
• K1, AUX1 Relay - 19B235003P1
• K2, AUX1 Relay - 19B235003P1
• DB25 Extension Ribbon Cable – 19B802395P1
7.5.1 Installation
To install the kit, insert the relays and the ribbon cable on the Interface Board as shown in Figure 7-11.
Figure 7-11: Squelch Operated Relay Option Installation
7.5.2 Operation
The SOR (K3) contains four form "C" contacts and is rated for 2 amps at 20 VDC. The relay operates
under control of signal RX_1_MUTE, which is derived from CAS, with the coil of K3 being picked up by
transistor switch Q110. (Refer to the SOR diagrams in Figure 7-12.)
AUX1 relay (K1) and AUX2 relay (K2) each contain two form "C" contacts and operate under remote
control. When AUX1 function is started via remote control, the system microprocessor sets signal
RXF3/AUX1 to logic high which turns on transistor switch Q112 picking up the coil of K1. When
AUX2 function is started, the system microprocessor sets bit 4 of output register U106 high, turning on
transistor switch Q111 picking up the coil of K2. When the AUX functions are stopped, the control bits
are toggled, and the relay coil drops out.

7.6 SHARED REPEATER PANEL INSTALLATION
This section provides information for installing and configuring the MASTR III Conventional ADC Base
Station for use with a Shared Repeater Tone Panel.
7.6.1 General
The MASTR III ADC Base Station may be used as a “community” or “shared” repeater. This allows
multiple users to share a common repeater. However, a common or shared repeater allows anyone
transmitting on frequency and in some cases undesirable noise to pass through or unsquelch the system.
This reduces the system availability and is annoying to radio users. To keep the nuisance listening to a
minimum, a sub-audible tone signaling system, the Continuous Tone Coding Squelch System (CTCSS)
and the Continuous Digital Coded Squelch System (CDCSS or DCS) were developed. In the MASTR III
Base Station these squelch systems are referred to as Channel Guard (CG) and Digital Channel Guard
(DCG). When used, an encoded sub-audible tone is sent over the air to the receiving station, which, in
turn, has a decoder. The decoder doesn't let any sound through to the speaker until it hears the specific
tone or code it was programmed to listen for. In the repeater system, decoding a given tone or code by
the receiver results in encoding the tone or code along with the repeated audio on the repeater transmit
frequency.
The MASTR III ADC Base Station can be programmed for multi-channel scanning with different CG
tones (CTCSS) or DCG (CDCSS) codes. Programming the station requires using the MASTR III
Programmer, (TQS3353) or MSEDIT (TQ0619) on site and scanning beyond two channels is impractical
because of the time involved.
One solution to making a MASTR III Base Station into a “community” repeater is to use an external
“shared” repeater panel or multi-tone CTCSS device. The repeater panel allows the system operator to
program the repeater and to remotely add or remove users. Some repeater panels add other features, such
as; audio processing, courtesy beeps, alarms, and timing and billing.
7.6.2 Repeater Panel Interface
The MASTR III ADC Base Station does not have a single connector for interfacing between the base
station and the repeater panel. As a result, it is necessary to fabricate a special cable with three
connectors or to solder wires directly to the backplane. The field engineer or installer should decide
which method is most practical. The most reliable and least expensive method is to solder the interface
wires to the connections on the backplane. However, a specially fabricated cable harness has definite
advantages in time saved when installing or troubleshooting multiple repeaters.
The following tables (Table 7-6 through Table 7-8) can be used to identify the signal lines that interface
with the repeater panel and where they can be found on the MASTR III ADC Base Station backplane (see
Figure 7-13 for Backplane connector locations).
MM102554V1 R1A
56
Table 7-6: Community Repeater Interface Signal Lines
SIGNAL NAME DESCRIPTION
RCVR_VOL/SQ_HI The receiver volume and squelch high line is the non de-emphasized output
from the RX IF board. The level for standard deviation is 1-Vrms. Expect
about 170 mVrms of CTCSS level when modulated at 15% system deviation.
SYS_VOL/SQ_HI The System Volume Squelch High lead is normally the same point as the
RCVR_VOL/SQ_HI. Jumper J11 must be removed from P11 on the backplane
to separate the two leads. The SYS_VOL/SQ_HI is the return path of audio to
the station. Removing the jumper and using this lead is undesirable.
Processing of speech audio will be performed by the system module and any
further external processing will complicate and sometimes cause problems.
Reasons for using this circuit however may include squelch tail elimination,
adding courtesy tones, or muting repeated audio. The overall gain of any audio
processing should be unity and with a flat frequency response.
CAS Carrier Activity Sensor (CAS) indicates the condition of the noise squelch
circuit. A TTL level high (5 Volts) indicates an on channel carrier while a logic
low indicates a lack of carrier.
EXT_LSD External Low Speed Data lead goes to the system module. There the lead is
switched to the high side of the CG electronic potentiometer. The level of the
encode CTCSS or CDCSS should be set to between 0.5 and 1 Vrms. The final
deviation level will be set by the CG electronic potentiometer during station
alignment.
REPEAT_PTT_IN Logic low or ground on this lead will key the transmitter and route audio from
the SYS_VOL/SQ_HI and EXT_LSD leads to the transmitter audio circuits.
A+ Unfiltered power coming from the main station power supply. This point is not
regulated to a specific value. Its voltage may vary with the load of the station,
but usually it makes a good point for providing A nominal 12 VDC to the
station. Do not use the +12 volt circuits to provide power to external devices.
DGND Same as the chassis ground of the station. Can be use for DC return path.
AGND Analog ground. Can be used to ground cable shields. If hum exists, add or
remove the shield from the AGND to eliminate the problem.

8. STATION TEST AND ALIGNMENT PROCEDURES
8.1 INTRODUCTION
This chapter provides instructions for testing and aligning the MASTR III Conventional or P25 Base
Station. The base station is normally pre-aligned at the factory and ready to install. However, after initial
installation and prior to placing the equipment into operation, it should be rechecked to ensure it is
operating properly and meets the required specifications.
These procedures assume the receiver and transmitter modules have been previously tuned and aligned
and should be used whenever a module or system component is repaired or replaced.
8.2 GENERAL
The MASTR III ADC Base Station comes pre-programmed and ready to install, the only adjustments
needed are the required Line Output Level, the Line Input Level necessary to produce Standard
Deviation, and the Line Cancellation for 2-wire Tone Remote Orientation. These adjustments can be
made using the PC Programming option TQS3353, the Utility PC software TQ0619, or with the Utility
Handset SPK9024.
The rated system deviations are as follows:
• 5.0 kHz Standard (25 kHz IF)
• 4.0 kHz NPSPAC
• 2.5 kHz Narrow (12.5 kHz narrowband)
• 2.8 kHz P25

4. Run the TQS3353 software and enter M3 to start the MASTR III program.
5. Initiate a RESET (on the Power Module) before programming starts.
6. The SQUELCH and VOLUME adjustments should be made for proper operation. Unsquelch the
receiver by turning the SQUELCH adjustment counter-clockwise. (If your base station has Channel
Guard, also activate the CG switch.) Verify that unsquelched noise is going to the speaker by
increasing the VOLUME (clockwise). Adjust the SQUELCH pot for critical squelch (squelch just
closes).
7. Verify the current personality or create a new personality as required. Do not change Pot settings.
8. Following the initial setup, the MIC port may be used for one of the following purposes:
a. Connecting the local microphone equipped with a modular connector.
b. Connecting the multi-purpose Utility Handset.
8.5 STATION ALIGNMENT
Alignment of the MASTR III base station was performed prior to shipment. The factory assumed the
following characteristics:
1. There is no loss or gain for repeated audio deviation.
2. If a remote exists, it is connected to the base station through a telephone line with 10 dB of loss.
3. The base station drives the line output at -10 dBm with nominal receive deviation.
The base station should deliver –10 dBm to the line with a signal applied with standard 3 kHz deviation.
A –10 dBm audio signal applied to the Station Line In should result in transmitter deviation of 3 kHz.
These values may be altered by following one of the alignment procedures as provided. For minor
adjustments, you may want to adjust only one or two digital potentiometers or leave the setting as set. In
any case, it is important to carefully examine the Alignment Diagram (Figure 8-3).
MM102554V1 R1A

NOTE
It is a good idea to record the potentiometer settings on paper, until you’re familiar with all
the digital potentiometer setting process.

Figure 8-3: MASTR III Conventional Base Station Alignment Controls
8.5.1 Preparation
Unless otherwise stated, all adjustments and alignments in this section are to be made using the MASTR
III PC Programming Utility Software (TQ0619). Tests may also be made using the Utility Handset
(SPK9024). Refer to the Utility PC Programmer Manual (LBI-38540) or the Utility Handset Manual
(LBI-38599) if necessary.
Perform the following steps before starting the alignment procedure:
1. Perform a controlled power up if station is not on. Check equipment for any abnormal indications
2. On stations that are assembled less MASTR III power supplies, supply adequate DC power to the
station from an external power supply. Adjust the input voltage to the PA to 13.4 ±0.3 VDC
(26.0 ±0.3 VDC for the EA101292 Power Amplifier).
3. Connect the signal generator to the antenna system jack in all but repeater combinations or duplex
stations. In repeater stations, a separate Receive antenna jack is provided.
4. For multi-frequency stations, activate the TX Disable switch on the System Module and select the
desired receive frequency using the PC.
5. Adjust the SQUELCH and VOLUME for proper operation. Unsquelch the receiver by turning the
SQUELCH adjustment counter-clockwise. Verify that unsquelched noise is going to the speaker.
Adjust the volume if needed (clockwise to increase level).
6. Terminate Line Input (TB101-2, 5), and Line Output (TB101-3, 4), with 600 ohms.

4. Measure the transmitter deviation. Verify the transmitted tone is 1 kHz and adjust the Repeater Gain
(RG) pot for the required deviation listed in Table 8-7 ±100 Hz.
5. Unkey the transmitter by releasing the REMOTE PTT.
6. Remove the input signal from the receiver.
7. Repeat this procedure for each channel.
8.5.6 DSP Line Input (DLI) Pot
The DSP Line Input (DLI) pot adjusts the signal level going to the System Module DSP board.
If this is not a remote station, set the DLI pot to zero (0).
For a remote station, perform the following steps to set the DLI pot:
1. Apply a 1000 Hz tone at -10 dBm (245 mVrms) to the line input (TB101-2 and TB101-5).
2. Execute a REMOTE PTT by setting the System Module REM PTT switch to the up position. This
keys the transmitter.
(This level is the function tone level, and is usually -10 dBm across 600 ohms, or 245 mVrms. This
level MUST be 10 dBm below the "maximum system audio level" even if your actual secur-it tone
and function tone are at the same level.)
3. Adjust the DSP Line In DLI Pot for 60% of maximum system deviation if operating with
compression. (Table 8-8).

4. Unkey the transmitter by releasing the REMOTE PTT.
5. Remove the input signal from the line input.
6. Repeat this procedure for each channel.
8.5.7 Compressor Gain (CP) Pot
The DSP Compressor (CP) Pot is used to indicate the setting, which determines the level of line input
voltage that will lead to compression. For remote systems using the DSP Compressor (all tone remote
systems use the DSP Compressor), this field should be set so that nominal line input audio results in
output audio, which is at rated (see Table 8-9).
If not a remote station set the CP pot to zero (0).
For a remote station, perform the following steps to set the CP pot:
1. Apply a 1000 Hz tone at -10 dBm (245 mVrms) to the line input (TB101-2 and TB101-5).
2. Execute a REMOTE PTT by switching the System Module REM PTT switch to the up position. This
keys the transmitter.

9. SYSTEM FUNCTIONAL TESTS
9.1 GENERAL
The chapter describes the methods for functionally testing the MASTR III Conventional Base Station.
Upon completion of these tests, the base station is considered operational.
9.2 SETUP
The following system functional tests may require up to four (4) portable or mobile radios of the type to
be used on this system (conventional analog or P25 digital) - ideally they should be specimens from the
customer’s order. Many of the tests will only require two of these to be used.
Program all test radios with a minimum generic personality. The personalities should closely reflect the
personalities of the customer’s radios where possible.
9.3 CONVENTIONAL RADIO TEST
This test verifies the operation of a conventional analog base station.
1. Set the radios to the desired system or channel.
2. Ensure the channel is not busy and make a series of radio calls.
3. Confirm that the transmission can be heard in the receiving radio.
4. Set the radios for coded transmission (if programmed) and make a series of coded calls.
5. Ensure the receiving radio decodes the call.
9.4 P25 RADIO TEST
This test verifies the operation of a P25 base station.
9.4.1 P25 Individual Calls
1. Ensure the radios and base station are configured for P25 operation.
2. Select the desired P25 system.
3. Select the radio unit to call (callee source ID) from the pre-programmed individual call list or enter
the ID number on the radio keypad.
4. Make the call.
5. Confirm that the called radio unmutes according to the squelch mode defined in the radio personality
(monitor, normal, selective).
9.4.2 P25 Group Calls
1. Ensure the radios and base station are configured for P25 operation.
2. On the transmitting radio, select P25 system and the desired Talk Group/Conventional Channel.
MM102554V1 R1A
75
3. On the receiving radios, select the desired P25 system and Talk Group/Channel or turn scan on and
make sure the desired channel is in the scan list.
4. Make the call.
5. Confirm that the called radios unmute and receive the P25 call. The radio will unmute according to
the squelch mode defined in the radios’ personality (monitor, normal, selective).
9.5 REMOTE STATION OPERATION
This test verifies the remote control of the base station.
1. In multi-frequency stations, check remote frequency control.
2. In channel guard stations, the MONITOR switch on the console should disable channel guard decode.
Momentarily keying the transmitter will re-enable CG decode.
3. For Tone systems with CG ENABLE/DISABLE:
• When the console is switched to CG DISABLE, CG Decode should be disabled. Keying the
transmitter will not enable CG Decode.
• Switching to CG ENABLE will enable CG Decode unless the MONITOR switch has been
depressed. The microphone monitor switch will disable CG Decode even if the CG
DISABLE/ENABLE switch is in the enable position.
4. Place a series of individual and group calls to radios. Ensure radios receive calls.
5. Make a series of calls using conventional and P25 (if applicable) radios and verify Remote Controller
can monitor and respond to calls.

10. MODULE TESTING AND ALIGNMENT
10.1 GENERAL
The chapter describes the methods available for testing and aligning individual modules. If modules are
suspected of being faulty, they should be tested and realigned by using one of the methods described in
Table 10-1.
Table 10-1: Module Test and alignment methods
TEST OR ALIGNMENT METHOD AFFECTED MODULES
Bench Testing
(Removing the modules from the Station and
using the TQ0650 RF Test Fixture)
All RF modules
In-Station Testing
(Using the extender cards)
All modules
WARNING
Before removing or replacing any module, power to the station must be switched off.
The preferred method for testing and aligning individual modules is to perform the Bench Test and
Alignment. This involves removing the module from the base station and using the TQ0650 RF Module
Test Fixture to test and align the module as described in section 10.2. After the module realignment is
complete and it is reinstalled into the base station, it will be necessary to perform a full station alignment
according to the procedures in chapter 8.
Individual modules may also be tested in the base station by using an extender card. Refer to section 10.2
for instructions on using an extender card to test individual modules.
There are two types of extender cards available for use with the MASTR III Base Station T/R Shelf. One
extender card extends the modules installed in the RF section and the other for modules in the control
section. Table 10-2 indicates which modules can be extended by each extender card.

10.2 BENCH TESTING
Bench Testing must be performed in a relatively clean shop environment using the TQ0650 RF Module
Test Fixture. Usually when a module is suspected of being defective or out of alignment, the affected
channel is to be taken out of service and the failed module is to be removed and replaced with a known
good module. If a replacement module is installed, the station should be completely realigned and the
channel returned to service. The module removed is then taken to a Maintenance Facility for bench
testing and alignment.
The TQ0650 RF Module Test Fixtures 344A4235P1 (no longer available) and the TS101285V1 are
capable of testing the modules listed in Table 10-3. Instructions for using the RF Module Test Fixture are
contained in manuals LBI-38805 (344A4235P1) and MM101885V1 (TS101285V1), which are included
in the TQ0650 package. These manuals provide instructions for setting up the test fixture and running the
test software. A personal computer is also required.
The test technician should refer to the applicable technical manual for the module under test for detailed
alignment requirements.
NOTE
There are no bench tests for the System Module. Should this module fail during in-station
alignment, it is to be replaced and the failed module returned for repair.
WARNING
Before removing or replacing a module, power to the station must be switched off.

10.2.1 Procedure
To remove a module for bench testing, the following steps are to be taken:
1. Switch OFF power to the affected channel (T/R Shelf).
2. Remove the module.
3. If possible, replace the module with a known good module and realign the Base Station and return it
to service.
4. Return the defective module to the test facility and connect it to the RF Module Test Fixture.
5. Bench Test the module according to the instructions in LBI-38805 or MM101885V1. Test and
realign the module if possible. If it fails the testing, it should be sent for warranty repair or
replacement.
When testing is complete, replace the module and re-check alignment as follows:
1. Power to the channel must be switched off.
2. Place the module into the correct slot in the station.

1. Remove power to the affected channel (T/R Shelf).
2. Remove the module and place the RF Module Extender Card into the T/R Shelf.
3. Insert the module into the Extender Card.
4. Reapply power to the channel (T/R Shelf).
5. Tests may now be performed. Refer to the applicable module maintenance manual for testing
information.
When testing is complete, replace the module and re-check alignment as follows:
1. Power to the channel must be switched off.
2. The Extender Card is to be removed and the module replaced into the correct slot in the station.
3. Power is to be reapplied to the channel.
4. Alignment must be verified and station realigned if necessary.
5. Return the channel into service.
10.4 CHANGING THE BASE STATION FREQUENCY
NOTE
The following procedures may be used in the field to retune a station if an RF module
has been repaired or replaced or the station frequency has been changed. The
preferred method is to use the RF Test fixture and the module alignment found in
section 10.2 and the specific RF module maintenance manual.
Changing the frequency in a MASTR III ADC Base Station requires frequency planning, examination of
the antenna system specifications, realignment of the RF system, and realignment of the Base Station.
The preferred method for retuning modules is to remove the modules from the Station as described in
section 10.2 and to use the RF Test Fixture to realign the RF modules.
The only modules that require realignment are the TX and RX Synthesizer and RX Front End modules,
but the remaining modules should be checked to ensure that they still operate correctly. When the
module realignment is complete, reinstall the modules and perform a complete station alignment using the
procedures in the Station Alignment section 8.4.
MM102554V1 R1A

If it is necessary to retune the modules in the field and an RF Test Fixture is not available, then use the
following procedures to realign the modules. The TX and RX Synthesizers can be retuned in the field by
using the metering functions available with the Utility handset SPK9024, MASTRUTL (TQ0619), or
MSEDIT (TQ0653). The VCO tune voltage from the RX Synthesizer slot in the T/R shelf is connected to
the external metering jack (EXT_JCK) in the System Module.

10.5 STATION ADJUSTMENTS FOR REMOTE CONTROL OPERATION
Although audio levels should be considered on a system basis, it is appropriate to set the levels of the
remote controller and the control station panel by themselves with reference to the levels required by the
transmission path and then connect the controller(s) and station to the path. The transmission path, if it is
more than just a simple twisted pair, is usually set up with a "test tone". The "average voice" level is
defined as being a certain number of decibels below the test tone. The test tone is normally the maximum
level that can be sent through the path without clipping or being regulated. Although there is no definite
agreement on the difference between the test tone and average voice levels, 10 dB is an appropriate level.
In order to align the Remote Controller and T/R Shelf properly, it will be necessary to have some
information on the transmission path. This will help to determine the levels at each end required by the
system. Specifications needed include:
1. Loss at 1 kHz
2. Test tone or maximum level
3. Average voice level (if defined)
4. Loss at 2175 Hz (if tone remote)
The DSP Board performs tone detection in a tone remote installation. The "Secur-it" tone Decoder on
this board has a dynamic range of approximately 9 dB. The system must be set up such that the "Secur-it"
tones from all remotes in the system arrive at the T/R Shelf within this 9 dB window.
10.5.1 Line Out Level Adjustment
U36-1 is used to set the line out level. Analog switch U14 selects which audio source is routed to the line.
Possible sources are LOCAL MIC, VOL/SQ, auxiliary receiver audio, auxiliary receiver audio summed
with VOL/SQ (simultaneous monitor), DSP LINE/TX AUDIO, MODEM LINE data, OPEN (used for
battery alarm), GROUND (used for no transmission, and LINE IN audio (used for four wire loop around).
A battery alarm tone and/or VG ALERT tone may also be summed in with whichever source is selected
with the exception of GROUND. Typically LOCAL MIC, VOL/SQ, DSP LINE/TX AUDIO, OPEN, or
GROUND will be selected.
The gains in the circuitry are set such that 100 mVrms in on MIC HI or 1 Vrms (3 kHz deviation) in on
VOL/SQ HI (REPEAT AUDIO) will produce the same line output level. The gains for VG ALERT tone
MM102554V1 R1A
83
and battery alarm are also designed to provide the proper levels without adjustments. The LINE output
level should be adjusted with a 100 mVrms, 1 kHz signal in on MIC HI or a 1 Vrms, 1 kHz signal in on
VOL/SQ HI.
10.5.2 DSP Line In Level Adjustment
Typically, the TX AUDIO and LINE OUT levels should be adjusted prior to adjusting the DSP LINE IN
level. DSP TX AUDIO and DSP LINE/TX AUDIO are typically line audio or VOL/SQ HI audio that has
been processed by the DSP Board.
A DSP Board is always present; this DSP processed line in audio will normally be selected by analog
switches U14 (DSP LINE/TX AUDIO to line out) and U15 (DSP TX AUDIO to transmit audio) on the
System Module when line in audio is selected. The level for DSP TX AUDIO and DSP LINE/TX AUDIO
must be adjusted on the DSP Board.
10.5.3 DSP Level Adjustments
The DSP LINE IN level into the DSP must be adjusted using U15-0 (DSP line cancellation level) and
U15-1 (DSP line input level) located on the DSP Board. If two-wire audio is used then both electronic
pots must be adjusted. If four-wire audio is used then only U15-1 needs to be adjusted.
For two wire installations the DSP line cancellation level pot (U15-0) is used to remove what the T/R
Shelf is sending to the line. While the T/R Shelf is sending received audio down the line, the line
cancellation pot should be adjusted to minimize the signal level at TP1 on the DSP Board. This leaves
only what is received from the remote. This signal is then level adjusted using the DSP line input level
adjust pot (U15-1) and input into the DSP.
NOTE
System Modules 19D902590G6 & G7 have TP1 extended to the board edge connector and
may be metered on the MASTR III backplane at J5, Pin 28A.
If four-wire audio is used, the DSP line cancellation pot must be set to zero.
The DSP also performs a compressor function on its DSP line input. The threshold for this compressor
must be adjusted as well. The line level should be adjusted on the DSP Board prior to setting the
compressor threshold.

11. PREVENTATIVE MAINTENANCE
11.1 GENERAL
Preventative Maintenance is a periodic check of the station’s operation. The results of the check may
indicate that the station needs realignment if its performance has drifted from the installation values or the
values documented in the previous inspection.
It allows for:
1. Operational test and re-adjustment of each Base Station’s alignment,
2. Operational test and re-adjustment of RF System equipment,
3. Operational test and re-adjustment of the Power System.
Preventative Maintenance should be performed every 6 months, or sooner if required by the customer.
The tests will follow those defined in this manual and will require the test engineer to refer to the
Installation Checklists or last Preventative Maintenance Checklists to determine any variance in
performance.
The results of these tests are to be recorded on the Preventative Maintenance Checklists in section 12.7
11.2 BASE STATIONS
WARNING
To disconnect the power to the base station for maintenance, unplug the power supply
from the AC outlet.
11.2.1 Test Equipment

same test equipment should be used for every channel at the site. If more than one of a particular type of
Test Equipment is used, ensure that they are calibrated to each other.
NOTE
For checking station frequency, a high accuracy reference is required (better than 1 part in
10-7). The internal oscillator on many counters is not sufficiently precise.
11.2.2 Tests
Refer to the “Station Test and Alignment” Section for detail of the tests. Perform tests to ascertain
current levels and note these on the Checklist. If adjustment is necessary, perform the realignment and
note the new levels and Control Pot settings for each test.
