MTR3000 Overview
The Motorola MTR3000 Base Station/Repeater provides a modular, flexible analog and digital
station design for today's communication systems and for the future. The station is available for
use in Analog Conventional, Digital Conventional (MOTOTRBO), MOTOTRBO Capacity
Plus Trunking and Connect Plus (UHF Only) multi site trunking configurations.
When configured for analog operation, MTR3000 can either be configured as a base station or
as a repeater. As a repeater, it listens on one uplink frequency, and then re-transmits on a
downlink frequency, thus providing the RF interface to the field subscribers. When configured
as a base station, MTR3000 is designed to operate with most existing analog systems.
When configured for digital operation, the base station/repeater offers additional services. The
digital base station/repeater operates in TDMA mode, which essentially divides one channel
into two virtual channels using time slots; therefore the user capacity is doubled. The base
station/repeater utilizes embedded signaling to inform the field radios of the busy/idle status of
each channel (time slot), the type of traffic, and even the source and destination information.
10
Page 12
Note: When configured in Digital Mode, MTR3000 can only be used as a repeater.
At any given time, MTR3000 either operates as a digital repeater or as an analog
repeater.
The MTR3000 base station/repeater is divided into functional modules that separate the
frequency band specific and transmitter power specific circuits from other circuits and has
separate modules for the control interface. These modules are self contained functional blocks
with module-specific alarms. This design facilitates the field replaceable unit (FRU) concept of
field repair to maximize system uptime. The description of the FRUs is as follows:
• The Receiver FRU is a dual heterodyne receiver which receives the RF signal from
the subscriber’s transmitter. It then converts the resulting final intermediate
frequency (IF) from an analog signal to that of a digital word. Finally, the receiver
delivers the digital word, via the data bus, to the SCM for demodulation.
Additionally, the receiver also provides its own metering and diagnostics via
software, as well as a self-contained calibration (no field tuning needed).
• The Exciter FRU converts a two-port base band data signal, sent over the data bus
from the SCM, to an analog signal representation. The analog signal then modulates
a low power RF transmitter carrier that is generated by the exciter. The low power
modulated RF carrier is then amplified and delivered to the PA for further
amplification. The Exciter and PA constitute the transmitter of the MTR3000.
Additionally, the exciter also provides its own metering and diagnostics via
software, as well as a self-contained calibration (no field tuning needed).
• The heart of the SCM FRU is that of two Texas Instruments OMAP series
processors, with each OMAP containing an ARM Host and a C55 DSP processor.
One of the two OMAP processors is dedicated to the receiver DSP operations, while
the other OMAP provides for all other functionality, which includes the transmitter
functions. In general the SCM provides for the entire coordination of the base
station/repeater functions, but more specifically, the SCM provides for the following
functionality:
‐ Contains and runs the preloaded base station/repeater software.
‐ Manages inbound and outbound RF and Audio traffic.
‐ Provides external speaker and microphone ports (analog only)
‐ Provides an on-board USB port for local configuring, alignment and
diagnostics via the following applications:
o Customer Programming Software (CPS),
o Tuner application
o Repeater Diagnostic and Control (RDAC) software.
‐ Provides an Ethernet port for IP site connectivity and remote RDAC.
‐ Provides GPIO connectivity for 3
rd
party controller interfaces.
‐ Provides analog base station audio connectivity.
‐ Data and Control to the receiver
‐ Data and Control to the exciter
‐ Control of the PA’s set power
11
Page 13
‐ Generates the internal station frequency reference.
‐ Provides control of the front panel status indicators.
• The PA FRU amplifies the low level modulated RF signal from the exciter module.
It then delivers the amplified signal to the transmitter antenna port at the rated power
of the base station/repeater, or less if the customer desires, for transmission to the
subscriber’s receiver. In addition to its primary task of amplification, the PA
provides the following hardware functions for the base station/repeater’s:
‐ Harmonic attenuation
‐ Intermodulation attenuation (IMA) suppression
‐ VSWR detection
‐ RF power control (primary means).
‐ Self contained cooling fan and control circuit
‐ Diagnostics
‐ Power rollback for temperature, VSWR, and voltage
‐ Self-Contained calibration (No field alignment for MTR3000 PAs only)
• The PS FRU provides DC power to the receiver, exciter, SCM, PA, and select third
party controllers via one or more of the three DC output taps; 28.6VDC, 14.2VDC,
and 5.1VDC. It can also provide auxiliary power to a number of third party
controllers. Additionally, it can operate in three different input modes:
‐ AC Input Only
‐ DC Input Only
‐ AC with Battery Revert
In addition to providing power to the noted FRU’s and controllers, the PS also
provides for the following:
‐ AC Failure detect signaling to the SCM
‐ Output over-current protection for all three outputs
‐ Self contained cooling fan and control circuit
‐ Thermal shut down if the environmental temperatures exceed the cooling
capacity afforded by the fan.
‐ Further details can be found in the individual “Theory of Operation” sections
of the respective FRUs.
• The Wireline FRU provides the connection to an analog audio source/sink (such as
a console) to the MTR3000 Base Station/Repeater. Specifically, the Wireline board
provides for the following:
Tone Remote Control
DC Remote Control
4-wire balanced audio connection
2-wire balanced audio connection

MTR2000 MOTOTRBO UPGRADE (Non-RTTE countries only)
Overview
The FRU architecture of the MTR30000 Base Station/Repeater allows the ability to upgrade an
existing MTR2000. An upgrade requires that the MTR3000 station core module (exciter,
receiver and station control module) be used to replace the MTR2000 exciter, receiver and
control module. The upgrade allows a customer to move from an analog platform to a digital
platform and increase their call capacity with the MOTOTRBO technology.

MTR2000 MOTOTRBO Upgrade Specs
When the MTR2000 is upgraded to an MTR3000, the specifications of the new components
(exciter, receiver and station control module) are the specs of the MTR3000 modules. (See
component specification tables.)
NOTE: The transmitter dynamic RF output power range will remain the same as it was
prior to the upgrade.

Page 17
MTR2000 MOTOTRBO Upgrade Installation
Upgrading an MTR2000 is a simple procedure. Depending on the proficiency of the technician
the hardware upgrade takes approx 15 minutes to complete per Base Station/Repeater.
Additional time will be required to program the station with the Customer Programming
Software (CPS) to the customer specific configuration. Before beginning the upgrade,
document the current code plug settings of the MTR2000, as they will need to be manually
entered into the MTR3000 CPS.
Note: The codeplug file format of the MTR2000 is not compatible with the codeplug file
format of the MTR3000, so manual entry of the codeplug configurations will be
required.
Compatibility
The following charts identify the system types, stations, and controllers that are compatible
with the MTR3000. Table 5 and Table 6 outline a direct feature comparison between the
MTR3000 and the MTR2000. It is imperative that the differences between the two stations are
understood when an MTR3000 is to be purchased for use in an analog system, as not all analog
features that were offered with the MTR2000 are available with the MTR3000. Furthermore,
the base station audio and control interface on the backplane has changed between the
MTR3000 and MTR2000 stations. These interface differences are noted in the “Adding
MTR3000 and/or Upgraded MTR2000 stations to MTR2000 sites” section of this manual.
Additionally, the MTR3000 platform offers a MTR2000 MOTOTRBO UPGRADE for existing
high-power UHF MTR2000 stations. When a MTR2000 station has employed the
MOTOTRBO Upgrade Digital Kit, the upgraded MTR2000 station will provide all digital
functionality that a factory new MTR3000 provides. Analog features offered in an upgraded
MTR2000 station are identical to that of a factory new MTR3000, however, there are subtle
differences in the analog connectivity at the J7 backplane connection between an upgraded
MTR2000 station and that of a factory new MTR30000 station. These differences are noted in
the “Adding MTR3000 and/or Upgraded MTR2000 stations to MTR2000 sites” section of this
manual.
Note: Since analog features will be lost with respect to the non-upgraded MTR2000, it is not
recommended to purchase a “MOTOTRBO Digital Upgrade Kit” for the MTR2000 if
one expects to operate the upgraded MTR2000 in analog mode. Upgrading the station
and operating in analog mode may be a temporary configuration while migrating the
subscribers. See Table 7 for specific configurations that are upgradeable.
The MOTOTRBO Upgrade Kit consists of the following individual items:
• MTR3000 Exciter FRU
• MTR3000 Receiver FRU
• MTR3000 Station Control Module FRU
• MTR3000 Front Bezel

Considerations before beginning a migration plan
The purpose of an MTR2000 MOTOTRBO upgrade is to allow users to migrate to
MOTOTRBO digital without having to purchase an entirely new station. When upgrading to an
MTR3000, use the following chart to ensure features and/or functionality is supported.

Note: An Upgraded MTR2000 can be used in analog mode. However, since some analog
functionality would be lost in this transition, this application would be best applied
to a customer who intends to migrate to MOTOTRBO at some time in the future.

SPECIFICATIONS
Specification Definitions
Listed alphabetically are the definitions of some of the specifications described above.
Information on whether the preferred specification would be smaller or larger is also given.
1) Adjacent Channel Power Ratio (Decibels/ dB): A measure of the level of undesired
transmit signal that falls within the adjacent frequency channel. Often this is limited
by the modulation type rather than hardware or software. A larger number is better.
2) Adjacent Channel Rejection {Selectivity} (Decibels/ dB)–Ability of the receiver to
detect the desired signal, while rejecting signals on adjacent channels. The benefit is
less interference. The preferred specification is larger. Effective system performance
may be limited by the interfering subscriber units’ transmitter noise or modulation
characteristics
3) Bandwidth: As it applies to T-T or R-R (Megahertz/ MHz)–The maximum
frequency separation from the lowest frequency to the highest frequency without
degradation of specifications. The preferred specification for multi-channel base
stations/repeaters should be wide enough to include all the channels that are used,
depending upon the application.
4) Bandwidth: As it applies to T-R Spacing (Megahertz/ MHz)–The specified
frequency separation between the transmitter and receiver is band dependent. The
preferred specification is generally smaller, although it depends upon the specific
site requirements.
5) Bit Error Rate Floor (%): A measure of the receiver’s ability to detect and decode
strong signals accurately. A small percentage is better.
6) Conducted Spurious Emissions (dBm): Undesired receiver output signals (on the
antenna port). The benefit is reduced interference with other base stations/repeaters
nearby. The preferred specification is a more negative number.
7) Co-Channel Rejection (Decibels/ dB): Ability of the receiver to reject on channel
interference. This specification is usually determined by the modulation type. A
smaller number is better.
8) Electronic Bandwidth: Operating range that can be obtained without any mechanical
adjustments, such as tuning screws. Larger number is better. Full bandwidth is best.
9) Emissions Designator: An FCC designator describing bandwidth and modulation
type.
10) Frequency Stability (+/-% OR parts per million/ppm OR parts per billion/ppb): The
ability to stay on the assigned frequency over a temperature range of -30° to +60°C.
The benefit is increased coverage, less interference and reduced background noise.
The preferred specification is smaller, which implies a greater stability.
11) Harmonic Emissions Attenuation (Decibels/dB): Similar to spurious outputs
(described below); multiples of the frequency of the final power amplifier
(transmitter). The benefit is reduced interference to nearby base stations/repeaters.
The preferred specification is a larger number.
12) Intermodulation Attenuation (Decibels/ dB): Reduces transmitter intermodulation by
preventing undesired signals from entering into the transmitter's PA. This is
26
Page 28
accomplished by using circulators or isolators. The preferred specification is larger.
This specification is especially important at dense sites.
13) FSK Error (%): A measure of the transmitter’s ability to accurately produce a
digitally modulated signal. A smaller percentage is better.
14) Receiver Intermodulation/IMR (Decibels/ dB)–Mixing of undesired signals which
interferes with the desired signal. This is important if the R-R bandwidth is large.
The benefit is less interference. The preferred specification is larger.
15) Sensitivity (Microvolts/µV or dBm)–The ability of the receiver to detect and
amplify weak signals. The benefit is increased coverage. 12 decibels SINAD is the
threshold for intelligible analog voice communications. The preferred specification
is smaller. 5% bit error rate is the threshold for intelligible digital voice
communication.
16) Signal Displacement Bandwidth (Off-Channel Acceptance) (kHz)–The amount the
signal can be off the tuned frequency and still be received. The preferred
specification is larger and must be at least as good as the frequency stability of the
transmitting subscriber units.
17) Spurious Emissions (Decibels/ dB)–Undesired transmitter output signals. The
benefit is reduced interference with other base stations/repeaters nearby. The
preferred specification is a larger number.
18) Spurious (Image) Response (Decibels/ dB)–Ability of the receiver to reject certain
types of undesired or interfering signals related to the operating frequency. The
preferred specification is larger.
For analog FM, TIA603D standards and methods are used unless otherwise noted for analog
specs. Specifications regarding digital modulation use TIA102 methods.

Power and Energy Consumption Curves
The power consumption and current draw curves displayed on the following pages reflect typical
performance. The power consumption and current draws are in reference to the RF output power at the
power amplifier’s output connector
Note, the DC power consumption and current draw curves only go down to a radio input potential of
25.7VDC for UHF and 24.7V for 800/900MHz as that is the lowest potential at which the radio is
specified to deliver the rated transmitter output power of 100W. The “Power Source” section of this
document outlines further considerations when the MTR3000 is operating under DC power.

X265 Base Station/Repeater Preselector (UHF)
The Base Station/Repeater Preselector provides additional rejection of unwanted signals
including the transmitter signals from overloading the receiver. The filter is optional for the
MTR3000 Base Station/Repeater. The base station/repeater preselector is not required when
using a receiver multicoupler system since the preselector in the multicoupler should provide
sufficient rejection. This filter can be retuned in the field.

X676 External Dual Circulator
The external dual circulator option provides 2 additional circulators and a low pass filter in a 2
RU tray. This option provides additional transmitter intermodulation attenuation. It is useful at
sites with other transmitters when the MTR3000 Base Station/Repeater connects directly to a
transmit antenna or duplexer. This option is not needed when a cavity combiner with built in
circulator (isolator) is used on the output of the MTR3000 Base Station/Repeater. The assembly
includes an input cable which connects directly to the output of the MTR3000 Base
Station/Repeater. The output is a panel mount N connector. No field tuning or alignment is
possible or required.
Note: The circulator load temperature monitor function will not be available in the initial
release of the MTR3000.
X676 (UHF)
For UHF, the units ship either as 403-470 or 470-512 MHz. The plots & specifications in the
figures below include the loss of the low pass filter & cables for the 403-470 MHz version.

Minimum Antenna Isolation
For frequencies 403MHz to 470MHz without a RFDS, a minimum of 65dB isolation must be
present between the receiver and transmitter antenna (including 2dB loss for each feed line).
For 10dB gain antennas, this corresponds to a minimum vertical separation of 26ft tip to bottom
with both antennas upright.
For frequencies 470MHz to 524MHz without RFDS, a minimum of 65dB isolation must be
present between the receiver and transmitter antenna (including 2dB loss for each feed line).
For 10dB gain antennas, this corresponds to a minimum vertical separation of 22ft tip to bottom
with both antennas upright.
For the 800MHz band without a RFDS, a minimum of 69dB isolation must be present between
the receiver and transmitter antenna (including 2dB loss for each feed line). For 10dB gain
antennas, this corresponds to a minimum vertical separation of 13ft tip to bottom with both
antennas upright.
Note: It is not recommended to rely on horizontal transmitter and receiver antenna separation
for the needed isolation as the distances required are impractical.
For frequencies in the UHF, 800, and 900 bands with a RFDS, use Table 15 and Figure 10 and
the characteristics of any RFDS (duplexers, etc) to determine the minimum antenna isolation.

MODULES
Power Supply Module
The MTR3000 Power Supply Module accepts an AC or a DC input and generates three output
DC voltages to power the station modules. All three outputs provide over-voltage / over-current
protection to their loads.
The power supply is a high-frequency switched mode design with power factor correction, all
contained in a metal heat-sink and mounted on the left-hand side of the station.
The AC input connection is made at the rear of the station via an IEC-type connector keyed to
accept only high temperature type mating connectors. Also provided is a DC input connection
which can be used as the primary means to power the station or used for battery revert
operation should the AC mains fail.
Power supply cooling is provided by a thermostatically controlled external fan (a field
replaceable part itself) which provides forced air across the power supply heat sink fins.
Power Supply Connections
There are two electrical connection assemblies on the PS:
• Power supply connection and AC fail indication to backplane (rear cable harness)
• Power supply connection to power amplifier (rear cable harness)
60
Page 62
PS Containment
The PS is secured to the station chassis with 6 TORX screws (T20 bit size required).

The Power Amplifier (PA) is a forced convection-cooled continuous wave RF power amplifier.
It accepts a low-level modulated RF signal from the Exciter Module, and amplifies the signal to
the end users selected transmitter output power.
The PA is designed for continuous-duty operation across the specified band for all power
levels. All PA modules contain a multi-stage power amplifier board at the input (RF Board), a
circulator with isolation load termination, a low-pass filter, and directional couplers at the
output (Output Board), and a DC Distribution Board incorporating circuitry for diagnostics and
RF power control.
The PA provides alarms for VSWR, Low Output Power, High Temperature, Low/High DC
voltage and Cooling Fan failures (cooling fan is field replaceable). In the event of these alarms,
with their severity weighed, the PA in conjunction with the station firmware will take measures
such as rolling the power back or de-keying the station to protect the hardware from damage or
improper operation.
The PA and its sub-circuits are broad-band devices and require no manual tuning or alignment
to operate at the site as their calibration parameters are stored in the PA’s EEPROM. As such,
in the event the PA requires replacement, no calibration is needed after its replacement.
Note: If the station is upgraded from MTR2000, refer to MTR2000 Basic Service Manual
(included with the original MTR2000 station) for all PA information.

Power Amplifier Connections
There are three electrical connection assemblies on the PA:
• Power supply (rear cable harness)
• Communications connector (rear ribbon cable).
• RF input connector (BNC female)
• RF output connector (N-Type female).
PA Containment
The PA is secured to the station chassis with 6 TORX screws (T20 bit size required).

Receiver Module
Figure 18. Receiver Module
The receiver provides the hardware portion of the receiver functionality for the station. The
receiver module performs selective band-pass filtering (varactor tuned) and dual downconversion of the desired RF signal. An application specific receiver IC then performs an
analog-to-digital conversion of the desired received signal and outputs a differential data signal
to the Station Control Module (SCM).
The receiver has the capability through CPS (Customer Programming Software) to be
programmed for an analog or digital mode. For analog mode, the receiver is programmed for
12.5 kHz and 25 kHz bandwidths, on a per channel basis. This allows a single station to be
programmed to function in various bandwidths without changing hardware
For UHF stations without the external preselector option, it is not recommended to allow a colocated transmitter frequency which is 36.675MHz above the receiver frequency.
Receiver Connections
There are two electrical connection assemblies on the receiver:
• Communications / Power / Digital signal (edge connector)
• RF input connector (BNC female)

Exciter Module
Figure 19. Exciter Module
The Exciter Module (in conjunction with the Power Amplifier Module) provides the transmitter
functions for the station. Contained within a metal clamshell housing, the Exciter board
generates a low-level modulated Radio Frequency (RF) signal that is delivered to the power
amplifier module for further amplification and output to the transmit antenna. The Exciter
Module interfaces directly with the Station Control Module (SCM), which provides control
signals and monitoring, and routes transmit digitized audio to the Exciter.
The RF carrier is generated by a frequency synthesizer consisting of synthesizer circuitry and
Voltage-Controlled Oscillator (VCO) circuitry. Exciter module control signals, monitoring, and
audio processing are handled by the Station Control Module (SCM).

Station Control Module
Figure 20. Station Control Module
The Station Control Module (SCM) performs station management, digital signal processing,
data formatting and audio routing for the base station/repeater. It provides interfaces to the
Exciter, Receiver and PA as well as the interfaces to external site equipment. The controller
uses two TI OMAP series processors: One for transmit and overall base station/repeater control
functions and one for all receive functions.
The audio interface provides flat and pre-emphasized transmit audio inputs as well as an
independent data/PL/DPL input. Transmit and receive audio signals are accessible on the rear
DB25 connector. A front panel microphone and speaker provide local audio (analog mode
only).
The 10/100BaseT Ethernet port is used to connect to station to a local or wide area network for
IP Site Connect and remote diagnostics & control. The front cover must be removed to access
this connector. Alternatively, a short extension cable can be used to route this connection to the
rear of the station.
A front accessible USB port provides the interface to the local service computer for radio
configuration.
The SCM provides the station frequency reference to the Exciter and Receiver module. A
TCXO (Temperature Compensated Crystal Oscillator) provides the stability required for UHF
and VHF bands and an OCXO (Oven Controlled Crystal Oscillator) provides the stability
required for 800/900MHz bands. An external frequency reference can be connected to a BNC
connector behind the front panel to calibrate the onboard TCXO/OCXO. The front cover must
be removed to access this connector.
If an external reference is to be used with the MTR3000, a short extension cable can be used to
route this connection to the rear of the station. Alternately, the reference cable (and/or Ethernet
cable) can be routed out the front of the station via the slots provided along the edge of the front
bezel.

Wireline Board
The Wireline Board is the interface between the MTR3000 base station/repeater and the customer’s phone lines.
The Wireline Board supports Local PTT, Tone, and DC Remote Control modes, of which the later two allow for
channel selection and PTT signaling from compatible consoles. The Wireline Board can be configured for either
2-wire or 4-wire operation as needed.
The Wireline Board uses Digital Signal Processing (DSP) techniques to implement all required remote control
functions, filtering algorithms, and audio adjustments. Audio enters and leaves the board as analog, but is
converted to digital in the interim for processing.

The Wireline board allows for configurable impedance matching to the greater wireline network. Line impedance
is generally standardized by country or region as shown in the table below. The line impedance setting is
configured using the CPS software configuration tool.
Table:. Selectable Wireline Impedances
Tone Remote Control
A tone sequence must meet specific requirements for timing, amplitude, and frequency to be considered valid.
The timing requirements for a tone sequence are defined in the tables below. All tone sequences must include a
minimum of 120 mS of high level guard tone and 40 mS of function tone. i.e. A function tone is required (even on
single frequency systems). Low Level Guard Tone (LLGT) is not required. This allows the console to change
frequencies or manipulate alternate CPS defined GPIO functions without keying up the base station/repeater.
When Low Level Guard Tone is present (at the end of a tone sequence), the base station/repeater will key up
and remain transmitting for as long as LLGT is present.
The following tables reflect the predefined tone plans the MTR3000 base station/repeater supports (+/- 10Hz):

MTR3000 INSTALLATION
Rack and Cabinet Installation, Placement & Site Design
Site Design
There are certain rules which must be followed when designing a site with base stations/repeaters which
are forced convection cooled. Since base stations/repeaters with forced convection cooling (fans) are
typically smaller than those without fans, the natural tendency of the site designer is install as many
base stations/repeaters in an area as possible. When cooling base stations/repeaters, the environment in
which the base stations/repeaters are installed is just as important as the actual heat sink designs for the
electronics. Some planning must go into the ventilation, and in most cases, air conditioning of the sites.
When an MTR3000 is placed in a cabinet, there must be vent openings on the sides for air to enter, and
vents in the back for air to exit. To make sure the airflow through the cabinet is not restricted there must
be a minimum of six inches of open area between the outlet of the air vent on the rear of the cabinet and
any airflow obstructions. It is also desirable to avoid exhausting heat on cables to avoid shortening
cable life span.
Warning: It is strongly recommended to NOT install batteries in the cabinet with the station.
Hydrogen and oxygen gases produced during electrolysis are colorless and odorless. The
hydrogen gas is of particular concern since it produces a potentially explosive
atmosphere when it reaches a 4% level of concentration in the air. The room containing
the battery must have sufficient natural or forced air ventilation to prevent a build-up of
gas exceeding 2% of the room's occupied volume. In addition, the gas must be vented to
the outside rather than re-circulated. Therefore, installing a battery in the cabinet could
cause serious venting problems.
A convenient location should be chosen with regard to power, control line, and antenna access. Refer to
the Motorola R56 Standards (hardcopy p/n: 68P81089E50-B, CD-ROM p/n: 98R80384V83) for proper
placement and installation of these lines. The base station/repeater should also be readily accessible for
future maintenance and servicing.
Providing adequate lightning protection is critical to a safe and reliable communications site. Telephone
lines, RF transmission cables, and AC and DC power lines must all be protected to prevent lightning
energy from entering the site building. RF transmission lines from the antenna, down the tower, and
into the building must be grounded. All RF transmission lines, including unused spares, must contain a
lighting surge suppresser. Further information can be found in the Motorola Quality Standards Fixed
Network Equipment Installation manual, R56 (Part # 68-81089E50).
Equipment shall be installed in site meeting the requirements of a “restricted access location”, per
UL60950-1, which is defined as follows: “Access can only be gained by service persons or by user who
has been warned about the possible burn hazard on equipment metal housing and hazardous energy
75
Page 77
level. Access to the equipment is through the use of a tool or lock and key, or other means of security,
and is controlled by the authority responsible for the location”.
Installation Considerations
Rear access is required for the MTR3000.
No clearance is required on the sides of the cabinet or racks; however, there must be provisions for
proper ventilation which allows for air intake by the PA and PS fans, which draw air in from the side.
Service access for the MTR3000 Base Station/Repeater requires a minimum of two feet in front and
rear of the rack or cabinet for servicing equipment.
Seismic Reliability
MTR3000 cabinets and open racks that are installed in seismically active areas may require additional
anchoring and support. Refer to your local regulatory agency requirements regarding seismic
considerations for your particular location. For installation guidelines, also refer to the Motorola
Standards and Guidelines for Communications Sites (R56) document (Motorola Part
Number 6881089E50).
Cabinet Stacking
Depending on the floor-to-ceiling height available, the MTR3000 cabinets and racks may be stacked. It
is necessary to securely fasten the bottom cabinet or modular rack to the floor or other rigid surface
capable of supporting the load of the stacked configuration. Order kit number TRN7750 for hardware
between two cabinets or modular racks that are stacked. The maximum number of cabinets or modular
racks that can be stacked is as follows:
The 30” Modular Rack can be stacked a maximum of 3 per stack (2286 mm (90 in.)).
The 45” Modular Rack can be stacked a maximum of 3 per stack (2286 mm (90 in.)).
The 52” Modular Rack can be stacked a maximum of 2 per stack (2640 mm (104 in.)).
The 30” Cabinet can be stacked a maximum of 3 per stack (2286 mm (90 in.)).
The 46” Cabinet can be stacked a maximum of 2 per stack (2337 mm (92 in.)).
The 60” Cabinets cannot be stacked.
Cabinet Mount
The mounting of only ONE STATION PER CABINET is recommended. More than one station per
cabinet will result in degradation of thermal specifications at high ambient temperatures. Appropriate
precautions should be taken to ensure that the station ambient temperature does not exceed +60˚ C
(+140˚ F). These guidelines apply to closed cabinets. For open cabinets (i.e., no doors or side panels),
refer to rack mount guidelines below for thermal impact.
76
Page 78
Rack Mount
Multiple MTR3000 stations can be mounted in an open rack without degradation of specification. To
maintain thermal specifications for equipment including the DLN6718 (Station Control OCXO),
MTR3000 stations require 1 Rack Unit of spacing between stations. For stations with DLN6718 that are
installed with no spacing, the station ambient temperature may not exceed +50˚ C (+122˚ F).
NOTE: The DLN6718 is standard/required in the 800/900MHz bands (T3000A and T2003A)
Adding MTR3000 and/or Upgraded MTR2000 stations to MTR2000 sites
An MTR3000 Base Station/Repeater can be added to existing repeater sites currently populated with
MTR2000 stations. The following physical connections are backwards compatible between that of an
MTR2000 and an Upgraded MTR2000/ MTR3000 station:
• External frequency reference
• RX antenna
• TX antenna
• DC Power
• AC Power
• Microphone (analog mode only)
• Speaker (analog mode only)
The peripherals that are used for the MTR2000 can remain in use for the MTR3000. There is no need to
change out any of the following peripherals if a MTR2000 is upgraded or an MTR3000 is used in place
of an MTR2000:
• Duplexer
• Preselector
• Dual circulator
• External frequency reference (EFR)
• Antenna relay
• Argus Battery Charger (L1884A)
The following connectors have changed between that of an MTR2000 and an Upgraded MTR2000 /
MTR3000. They are as follows:
• Service port -- It is now a type B female USB
• Wireline Connector (Backplane J6) -- It is now a detachable screw terminal block.
Note: This connection is not functionally supported in the initial release of the MTR3000.
77
Page 79
Analog Radio Interface
The analog radio interface at the System (J5) and Aux (J7) backplane connections has extensively
changed between that of an MTR2000 and an Upgraded MTR2000 / MTR3000. All existing cables that
connected to a MTR2000 station’s J5 and J7 connector can not be used with an Upgraded MTR2000 /
MTR3000. In general, all analog radio interfaces will be made at the J7 connector on the MTR3000.
Details of the signals are provided in the “Backplane Connections” section of this manual.
The 3rd party controller cables that will connect to the MTR3000 J7 connector can be fabricated by the
aid of the wiring diagrams provided in the Basic Service Manual (Appendix D). Alternately, the cables
for the following 3rd party controllers can also be obtained directly from the noted manufactures.
• Model 30 World Patch (Motorola, X244AH)
• Model 38 Community Repeater Panel (Motorola, X244AJ)
NOTE: The MTR3000 base station/repeater doesn’t require the use of the Wireline Board to support the
above mentioned 3rd party controllers. This is being noted since the MTR2000 did require the use of its
Wireline Board to support said 3rd party controllers.
Wireline Interface
The Wireline interface to the MTR3000 base station/repeater is provided by a the MTR3000 Wireline
Board. Although the Wireline is installed as a card inside the MTR 3000 Base Station/Repeater, its
operation is similar to an External Tone Remote or a DC Remote Adapter. The Wireline Board drives
the same GPIO signals that an external controller would drive if it were connected to the J7 DB-25
connector on the back of the base station/repeater. Although the Wireline Board’s functionality is
similar with an external controller solution, almost all Wireline options are configured through the CPS
and Tuner software configuration tools, just as the other base station/repeater options are.
The salient differences between the MTR3000 and MTR2000 Wireline functions are as follows:
• The MTR3000 Wireline supports (and the MTR2000 does not) the following:
- DC remote
- 2-Wire, 4-Wire, and multi-national impedance support with one FRU
- CPS configurable impedances
- FCC part 68 compliance
- Preconfigured tone tables
• The MTR2000 Wireline supports (and the MTR3000 does not) the following:
- Dynamic tone tables
- Multiple commands per tone
- 8-Wire
NOTE: The MTR3000 Wireline Board will not function in the MTR2000 base station/repeater
78
Page 80
GPIO and Audio Configuration
The configuration of the MTR3000 GPIO and audio types for the various controllers noted in the
“Analog Radio Interface” and “Wireline Interface” sections can be accomplished with the CPS
application. Details of the specific configuration settings are noted in Appendix G of the Basic Service
Manual.
Incompatible MTR2000 FRUs and Boards
The MTR2000 wireline boards are not compatible with an upgraded MTR2000 / MTR3000 station.
After a MTR2000 has been upgraded, its existing wireline board (if present) should be removed.
Additionally, the Aux I/O board from the MTR2000 will not be supported in the initially releases for
the upgraded MTR2000 / MTR3000. However, the COR and PTT functions (TIA986 E&M compliant)
are planned to be supported in future releases via the MTR2000 Aux I/0 board.
The Main / Standby feature was often employed in the MTR2000 station, which required the Wild Card
Option as well as the Aux I/O card itself. The upgraded MTR2000 / MTR3000 will support a version of
the Main / Standby function as a standard feature. The configuration parameters to invoke this
functionality are noted in the MOTOTRBO System Planner.
Note: With the Upgraded MTR2000 / MTR3000, once the standby station is the active repeater, the
main repeater will be locked out of service even if its fault recovers. To unlock an Upgraded
MTR2000 / MTR3000 station requires a local read / write of the station codeplug after the fault
condition is corrected.
Lastly, MTR2000 receivers, exciters, and control FRUs can not be used in conjunction with any
MTR3000 receiver, exciter, or control FRU.
MTR3000 and Upgraded MTR2000 Analog Radio Interface Differences
Via the components of a MTR2000 MOTOTRBO Digital Upgrade (T2003A), an upgraded MTR2000,
will provide identical functionality to that of a MTR3000 with the exceptions of the following:
• The PA “sticker code calibration coefficients” must be entered into the codeplug for an
Upgrade MTR2000 since the original MTR2000 PA does not have an onboard EEPROM for
their storage.
• The Upgraded MTR2000 J7 backplane connector does not provide the accessory 14.2VDC
(pin 20) or GPIO_10 (pin 5) functionality. For the Upgraded MTR2000, these signals must
be accessed at the J5 System connector.
• The Upgraded MTR2000 will not support the MTR3000 wireline card, which provides
integrated tone and DC remote control.
nd
• NOTE: In regards to the 2
and 3rd bullets above, an Upgraded MTR2000 can support said
J7 backplane connections as well as the MTR3000 Wireline Board if the MTR2000
backplane is replaced/upgraded. The part number of the replacement/upgraded backplane is
DLN6721.

MTR3000 and Upgraded MTR2000 Analog Radio RF Performance Differences
An Upgraded MTR2000 and MTR3000 will provide the same RF receiver and transmitter performance
with the exception that the MTR3000 will allow an extended RF power out range for the high power
models. The power output range of an MTR3000 is 8W-100W (UHF and 800/900), while an Upgraded
MTR2000 or MTR2000 has a power output range of 25W-100W (UHF) and 20W-75W (800 or 900).
Station Grounding
The MTR3000 Base Station/Repeater is designed to accept a grounding cable adjacent to the receiver
antenna connection at the rear of the station. An M8 tapped hole in the Power Supply module is
equipped with a M8 machine screw with external tooth star washer. The grounding cable lug should be
securely fastened to this point, which is marked with the international ground symbol. Refer to the
Motorola R56 Standards (hardcopy p/n: 68P81089E50-B, CD-ROM p/n: 98R80384V83) for grounding
cable specifications and routing guidelines.

POWER SOURCE
Block Diagram of AC & DC Flow
The MTR3000 Base Station/Repeater can operate from either AC or DC power as its primary
power source. The MTR3000 Base Station/Repeater can also provides battery revert
functionality when both an AC and DC source is interfaced to the Base Station/Repeater.
When both AC and DC sources are supplied, the station will operate from the AC power source
unless the AC power source is interrupted, at which time the station will automatically revert to
the DC power source.
Operation returns to the AC source when the AC source is restored. Switchover from AC to DC
and back again is fully automatic. No operator action is required. Figure 50 shows the AC and
DC power distribution in the MTR3000 Base Station/Repeater when an AC with battery revert
system is employed.
Note: When both AC and DC sources are present at the station power supply, AC will always
take precedence.

It is important to note that when the Upgraded MTR2000 or MTR3000 is running from a DC
source, the maximum RF output power is dependent on the station power supply’s DC input
voltage. Figure 24 shows a graphical representation of what the maximum RF output power is as
a function of the DC input voltage of a UHF station and figure 25 shows the maximum RF
output power as a function of the DC input voltage of a 800/900MHz station.
From Figure 24 and 25, the following can be seen:
• The station’s max output power is equal to 0W when; 21.6VDC > DC input voltage
> 32VDC
• The station’s max output power is equal to 65W when; 30.7VDC < DC input
voltage ≤ 32VDC
• For UHF, the station’s max output power is equal to 100W when; 25.7VDC ≤ DC
input voltage ≤ 30.7VDC
• For 800/900MHZ, the station’s max output power is equal to 100W when; 24.7VDC
≤ DC input voltage ≤ 30.7VDC
• The station’s max output power is equal to (DC input voltage – 21.6) * 10 + 60;
when 21.6VDC ≤ DC input voltage < 25.7VDC
Note: 21.6VDC and 32VDC are the specified operating limits of the station. Beyond those
limits, the power supply of the station will power itself (and the Base Station/Repeater)
down for its own protection as well as the batteries.

Number of Battery Cells
When AC power is interrupted in a battery revert configuration, a typical 12 cell lead-acid
battery (two 6 cell battery packs) will yield approximately 25.2VDC. Notice from Figure 24 that
25.2VDC results in a maximum of 95W output power at the initial moment of the battery
bank’s discharge.
If a 13 cell lead-acid battery is used (13 individual cells) instead, the battery bank will yield
approximately 27.3VDC, which would allow the full maximum output power of 100W to be
achieved. All other things being equal, this will also result in a longer run time in battery revert
mode before 21.6VDC is reached. This configuration can be supported by the charging system
noted in the “Battery Charging System and Wire Gauge Determination” section of this
document.
Battery Charging System and Wire Gauge Determination
The MTR3000 station does not provide an integrated battery charging function. If battery
charging is required for battery revert functionality, then the use of an external Motorola
approved battery reverting charger is required. See
Table 31. MTR3000 J5 System Backplane Connections
Table 31.
• L1884 Battery Reverting 24V DC charger requires, in addition, the following cables:
o CDN6226A CHGR LOAD CABLE MTR2000 ( to connect the Battery
charger with the MTR3000 Base Station Power Supply)
o CDN6227A CHGR BAT CABLE MTR2000 (to connect the Battery charger
to the battery)
Consult the Battery Reverting Charger Detailed Technical Specifications for information regarding
charger specifications, battery selection, wiring gauge determinations, and precautions.
AC Breaker Recommendation
Each MTR3000 should have its own AC supply breaker in order to ensure that a fault which
causes the breaker to open does not result in the loss of multiple transmit channels. However,
multiple MTR3000 stations could be supported on a single circuit (see “Power and Energy
Consumption Curves” section).
86
Page 88
For a 120 VAC, 60Hz application, the AC supply breaker should be rated for a continuous
current of no less than 15A, with a recommended rating of 20A.
For a 220 VAC, 50Hz application, the AC supply breaker should be rated for a continuous
current of no less than 15A, with a recommended rating of 20A.
The above breaker current ratings are per R56 guide lines for communications equipment.
DC Breaker Recommendation
For information involving the sizing of cables and DC power distribution, please refer to the
Motorola R56 standard Standards and Guidelines for Communication Sites (68P81089E50).
For each MTR3000 Base Station/Repeater, the DC supply breaker should be rated for a
continuous current of 20A.

STATION MAINTENANCE & ALIGNMENT
Routine Maintenance
The station has been designed with state-of-the-art technology and operates under software
control, thus requiring minimal routine maintenance. Virtually all station operating parameters
are monitored and self-corrected by the Station Control Module (SCM), making adjustments
and tuning virtually unnecessary. Provided that the equipment is installed in an area which
meets the specified environmental requirements, the only routine maintenance task required is
the yearly calibration of the station reference oscillator circuit.
Annual cleaning is recommended for dirty sites.
Alignment
The MTR3000 requires the alignment of up to three parameters. They are as follows:
• Modulation Limit: The alignment is only needed in cases where the station is
interfaced to a 3rd party controller that requires the use of the TX Data port on the J7
backplane connection.
• Power Output Calibration (Upgraded MTR2000 Only): This alignment is to allow
entry of the PA “sticker code calibration coefficients” into the stations codeplug.
• Speaker Volume: This alignment is for the adjustment of the speaker port audio
output level. (analog mode only)
• Station Frequency Reference: Recommend to be verified / aligned once per year to
maintain regulatory compliance.
Customer Programming Software
The Customer Programming Software (CPS) is the tool used to configure and service the base
station/repeater. The CPS runs on a PC laptop or desktop.. The CPS program will be able to
configure and service any device supported by the CPS. Once the configuration information has
been read from a device, the CPS will tailor its menus and service screens to fit the needs of
that device.
The CPS is designed to run the currently supported Microsoft Windows Operating Systems
such as Windows XP Home and Professional, Windows 2000 & Vista.
The PC used to run the CPS requires at least 100 MB of free space to install the CPS. CPS
software comes on a CD thus a CD drive is needed on the PC. Communication with the
MTR3000 Base Station/Repeater requires both a serial port and an Ethernet port.
88
Page 90
The CPS install disk contains three CPS applications; CPS, Repeater Diagnostics and Control
(RDAC), and Tuner. Each of the three applications contains on line help to aid the user in
configuring and aligning the station. In general, the purpose of the three applications is as
follows:
• CPS: Is radio programming software for dealers and service technicians who need to
configure the MTR3000. The CPS allows the user to access and program (e.g. read,
write or clone) the codeplug of the MTR3000 in the available systems.
• Tuner: Is an application that allows for the alignment of the MTR3000 (Modulation
Limit, Speaker Volume, and MTR2000 Upgrade PA sticker code entry). It also
allows testing of the MTR3000 (Bit Error Rate).
• RDAC: Is an application for the system technicians who need to run diagnostics on
the MTR3000. It allows the user to remotely or locally monitor the status of the
radio and gather real-time radio hardware failure reports via alarm messages
reported by the radio. In addition to the diagnostics capability, the application also
allows the user to remotely control some of the parameters of a radio. The
application can be used in a Single-Site (Local mode) or IP Site (IP Site mode)
environment with the main purpose of maintaining all the radios registered within
the system.
The MTR3000 and the MTR2000 MOTOTRBO Upgrade both use model GMVN5141 CPS.
This is the same CPS that is used to program the MOTOTRBO mobiles, portables and DR3000
station. The software is developed to recognize the station it is programming; therefore you
may see different options in the MTR3000 programming software that you have not seen in the
DR3000.
MTR3000 stations use a standard type A to type B USB cable for connection to the CPS
computer.
The cables used to program each MOTOTRBO product may be different. Refer to the
MTR3000 and the DR3000 ordering guide and price pages to determine the cable that is
required.
Base Station Software and Future Software Upgrades
The MOTOTRBO analog and digital software is pre-loaded on the Station Control Module. The
station control module comes standard in the MTR3000 as well as the MTR2000 MOTOTRBO
Upgrade. As software updates become available it can be downloaded for customers who have
purchased either product. Station software releases are available approximately twice a year and
are located on Motorola on line (MOL).
Periodically software features will be released that are available for purchase. Capacity Plus
(HKVN4045A) is a software feature that fits into this category. You can purchase multiple
software feature upgrades to one station unless otherwise noted. If the base station software is
upgraded as described above you will maintain your license for the software features that have
been purchased. For example if you purchase the Capacity Plus license and then download
version 1.6 software from MOL your Capacity Plus software feature remains in the station.
