Supported Repairs
The STRATA TX System, including the TXU, TCU, and optional
ACU, is designed to be compact, rugged and reliable.
The TXU and TCU require specialized test equipment to
calibrate amplitude and frequency characteristics after repair. In
addition, sealing the TXU, TCU, or optional ACU enclosures
after repair requires exacting techniques and special fixtures to
ensure weather resistance of the units.
Therefore, there are NO supported field repairs to either the
TXU, TCU, or ACU.
Return the entire unit for factory repair.

FM Modulator or COFDM/MPEG module, but not both. A High
Power Unit (HPU) is also contained within the TXU housing to
increase RF power output.
Product Description
2-2
TCU The Transmitter Control Unit (TCU) can be equipped with
either an FM Modulator or COFDM/MPEG module, or both.
ACU The optional AC to DC Power Converter (ACU) provides
+28 VDC power from an AC power source to power one or more
units in a system.
Remote Control Panels Optional Remote Control Panels are
available to allow remote control of the STRATA TX System from
an instrument panel during airborne or mobile operations.
2.2.2
Single Unit Systems
The TXU or TCU may be used independently in single-unit
applications as follows:
•
The TXU may be used as a stand-alone transmitter
accepting an IF input.
•
The TXU may be used as a stand-alone transmitter
featuring FMT modulation or MPEG and COFDM.
•
The TCU may be used as a stand-alone unit used for
FMT modulation or MPEG and COFDM, or both FMT
modulation and MPEG and COFDM.
2.2.3
Multi-Unit Systems
The TCU may contain the FMT modulator and MPEG/
COFDM module supplying an IF signal to a TXU
containing only the RF transmitter.
•
The TXU may contain the RF modulator or MPEG/
COFDM module supplying an RF signal directly to the
transmitter antenna.
•
The TCU can be separated from the TXU in applications
STRATA TX Operator’s Guide/Tech Ref Manual
2.2.4
Remote Control Options
For portable mobile or airborne operations, the STRATA TX
System may be controlled by one of two models of Remote
Control Panels. The Remote Control Panels are mounted in
mobile racks or aircraft instrument panels and are connected via
an RS-232 cable between the Remote Control Panel and the
STRATA TX System.

VDC power supply. Do not exceed +36
VDC input power or damage will occur.
2-3
Power Options The STRATA TX System configurations
operate on +28 VDC power, supplied externally. This DC power
can be supplied by the optional STRATA ACU, or from another
DC power source. Contact your Sales Representative for the
latest details.
Note
A TCU and TXU are defined as being “co-located”
when the TXU and TCU are physically separated
by not greater than 6 feet.
If the TXU and TCU are co-located, power must be supplied to
each unit through their individual power connectors from the
same power source. See Figure 2-2. Do not use DC on coax to

DC power superimposed on the coaxial cable between a TCU
and a TXU can be supplied from either the TCU or TXU,
depending upon the location of the DC power supply. Coaxial
cable length/voltage limitations exist when powering from either
the TXU or TCU. These limitations are based on cable size, DC
voltage input, cable resistance, and cable length. A maximum
length of 600 feet (180 meters) between the TXU and TCU is
supported. Contact MRC Technical Support for more information
on cable requirements.
DC power required for a STRATA TX System depends upon the
TX System configuration, i.e., if the TXU or TCU are operated in
a standalone mode, if the TXU and TCU are co-located, or if the
TXU and TCU are mounted in separate locations. See Figure 25 on page 2-6 for the various STRATA TX System configurations
available.
For TX Systems that use DC power sources other than a
STRATA ACU, contact MRC Technical Support for additional
power information.
2.2.6
Mounting and Deployment Options
The STRATA TX offers a number of options for either mobile or
portable applications.
For more details on installation of the STRATA TX in various
applications, see the “Installation” Chapter on page 6-1 (part of
the STRATA TX Technical Reference Manual only).
Mobile Installation For mobile applications such as in a vehicle
or in an aircraft, the STRATA TX System is usually mounted in an
MRC fixed mounting bracket and is installed in a bulkhead or
compartment. The cabling is permanently installed and power
comes from aircraft or vehicle power.
Portable Deployment In portable applications, the STRATA TX
STRATA TX Operator’s Guide/Tech Ref Manual
System will be moved from place to place and set up each time.
The TXU and TCU will usually be mounted in a MRC universal
mounting bracket. The bracket is attached to a tripod using a
mounting plate and quick release.
The cabling between the TXU and TCU is typically left in place
and the power, antenna, and audio/video connections are
removed at the end of each deployment.
2.2.7
System Integration
System Communication When the TXU and TCU are
connected, they automatically communicate via signals
superimposed on the coaxial cable between the two units. This
allows them to share information on installed hardware, preset
configurations, current status, and alarms.
System Operation Once the TXU and TCU are connected and
communicating, the units work seamlessly together. System
settings can be selected and modified from the front panel of
either unit, regardless of which unit holds the hardware being
configured.
System Configuration The STRATA TX System offers two
levels of system configuration, designed to match the needs of
different personnel.
For the field operator, the STRATA TX System has up to 9
Presets that can be selected from the front panel. Each Preset
controls key parameters such as modulation, frequency, and
audio and video settings. Additional settings that are front panelcontrolled include band, channel, offset, and filtering.
For the advanced operator and technical staff, the STRATA TX
Configurator software allows complete control of all parameters
in the STRATA TX System. The STRATA TX Configurator
software runs on a Windows-based PC and connects to either
the TXU or the TCU via an RS-232 serial interface cable.
Product Description
2-5
Interfacing a PC to either the TXU or TCU in a connected system
gives you complete control of both units. You can read the
current settings, program new settings, or return the units to their
factory default settings. The STRATA TX Configurator software
automatically detects what hardware is installed in the system
and assigns the appropriate configuration to the correct
hardware, regardless of which unit holds the hardware being
configured.

This section will provide more details about each the
components of a STRATA TX System:
•
STRATA TXU
•
STRATA TCU
•
STRATA ACU
•
STRATA Remote Control Panels
For details on connections between the STRATA TX System
components, refer to the “Installation” chapter (part of the
STRATA TX Technical Reference Manual only).
2.3.1
STRATA TXU
The TXU (Figure 2-6) always contains an IF/RF module that
accepts either a 70 MHz COFDM, FMT IF, or external 70 MHz
input signal and up-converts these signals to the required RF
band. The RF frequency synthesizer circuit included in the IF/RF
unit, in conjunction with the command and control power supply
module, provides the means to channelize RF video and audio
signals in the TX System RF band.
The TXU, with either an analog (FMT) or digital (MPEG/COFDM)
module, is integrated in the same housing as the HPU
components. This provides the ability to incorporate high RF
power output (12 watts of saturated RF power) into a single
analog or digital transmitter assembly.
Standard U.S. FCC band plans, as well as customer-created
channel plans, may be customized using the STRATA TX
Configurator software.
As noted previously, the TXU may also include either an MPEG/
CODFM or FMT module (but not both), in which case the TXU
serves as a stand-alone digital or analog video microwave
transmission system.
2.3.2
STRATA TCU
The TCU (Figure 2-7 on page 2-8) may contain either analog or
digital or both analog and digital video modulation modules.
Where an application might initially employ only analog video
transmission but expects to migrate to dual, switchable, analog
and digital operation, the TCU may be upgraded to add the
MPEG/COFDM module to add this capability.
STRATA TX Operator’s Guide/Tech Ref Manual
Product Description
2-7
Figure 2-7: STRATA TCU
Figure 2-8: AC to DC Converter
DC
OUTPUT
Where only digital or analog video transmission is desired, the
MPEG/COFDM or FMT modules may be installed in a TXU,
thereby eliminating the need for a TCU. The STRATA TX design
does not permit splitting digital and analog video modulator
modules between a TXU and a TCU.
A TCU may also consist of a stand-alone configuration whereby
either or both MPEG/COFDM and FMT modules may be used
independent of the TXU. This configuration permits use of a TCU
equipped with analog and/or digital video modulation modules
for a variety of signal input and output configurations, including a
digital option using NTSC or PAL composite video input and ASI
(digital) signal output.
2.3.3
STRATA ACU
For fixed or portable deployment applications, the STRATA TX
System may be powered by the optional AC to DC Converter
(ACU). Figure 2-8.
The ACU installs as part of an integrated stack for either tripod or
fixed applications. The ACU may also be used to power the TXU
or TCU only when a TXU and TCU are not co-located. In this
case, the TXU would receive DC power from the TCU or the
TCU would receive DC power from the TXU superimposed on
the coaxial cable connected between the units.
In standalone TXU or TCU operations, the optional ACU may be
used to supply DC power directly to the applicable unit. In the
case where a TXU and a TCU are co-located, it is recommended
that both the TXU and TCU be powered directly from the ACU in
lieu of supplying DC power from the TCU to the TXU or from the
TXU to the TCU via the coaxial cable connected between the
units.
2.3.4
STRATA Remote Control Panels
For mobile or airborne operations, two Remote Control Panel
models are currently available. Contact your Sales
Representative for the latest information.
Both Remote Control Panel models provide simplified transmit

analog or digital pre-configured Presets, Channels, and Offsets,
depending upon the required operating mode.
For additional information, refer to the STRATA Aircraft Remote
Control Panel Operator’s Guide (part no. 400490).
Standard Remote Control Panel The standard STRATA

TXU and TCU Configurations
TXU Different configurations of the TXU are available,
depending upon if your TX System contains a standalone TXU or
if your TX System contains both a TXU and TCU. The different
configurations are described below.
Aircraft Remote Control Panel The STRATA Aircraft Remote
Control Panel (Figure 2-10) is a simplified version of the
standard STRATA Remote Control Panel. This panel provides
instrument panel remote control of the STRATA TX System for
airborne operations. This model features only two Presets for
ease of operation.
If your TXU is equipped with either an analog (FMT) module or a
digital (MPEG/COFDM) module and was ordered to operate in a
standalone mode without a TCU, the front panel will contain an
AUDIO connector. See Figure 2-11 on page 2-10.
The unit is designed to fit a standard aircraft instrument panel
and provides user-friendly controls, combined with well placed
and easy to read LED displays and color indicators.

Each installation or deployment will have its own specific tasks
according to the application and the installed hardware.
3.3.1
Mobile Installation
For mobile applications such as aircraft or vehicle, the STRATA
TX System is usually mounted in a bulkhead or compartment
using an MRC Fixed Mounting Bracket (Figure 3-5). Mounting
brackets are available to mount from one to three units.
Quick Release

3.3.2
Portable Deployment
For situations where you need to mount a STRATA TX System
and its Fixed Mounting Bracket to an MRC tripod, MRC also
offers a Quick Release. See Figure 3-6.
For situations where you are mounting to another type of tripod
that doesn’t directly accept the Quick Release, consult with MRC
or your tripod manufacturer. MRC has Dovetail Adapter Plates
that will convert some types of tripods to accept the Quick
Release.
For portable applications where the STRATA TX System will be
moved from place to place and set up each time, the system will
usually be mounted in an MRC Universal Mounting Bracket. The
Universal Mounting Bracket will then be attached to a Quick
Release for easy mounting on an MRC tripod (See Figure 3-7 on
page 3-11).
Universal Mounting Brackets (See Figure 3-7 on page 3-11) are
required for each unit in the STRATA TX System, i.e., TXU, TCU,
and an optional ACU.
For applications using multiple units such as a TXU, TCU, and
an ACU, a Mounting Plate is also used to provide additional
stiffness. The Mounting Plate (See Figure 3-7 on page 3-11)
typically remains attached between the Universal Mounting
Bracket and the Quick Release.
The cabling between TX System units is also typically left in

Powering the STRATA TX System
The STRATA TX System will be in one of two configurations
which provide different options for controlling application of DC
power between units. Model variations are as follows:
Superimposing DC Power In this configuration, DC power is
superimposed with the IF signals between units and there is no
manual control of DC power from the TCU. The DC power is
superimposed on the coaxial cable between the TCU and the
TXU.
To turn DC power on and off, the operator uses the TCU and
TXU front panel PWR switches and either the TCU or TXU
Control Switch and alphanumeric display menus. The TXU DC
ON COAX switch must be set to ON.

TXU and/or TCU Control
Operations
This section describes how to configure your STRATA TX
System using the front panel Control Switch. Turning the front
panel Control Switch counterclockwise on either the TXU or TCU
controls transmitter functions including changing Presets,
changing RF channel assignments, setting RF attenuation
levels, and activation of DC power from a TCU to a separately
located TXU, or from a TXU to a separately located TCU.
Settings may be changed on a standalone TCU, a standalone
TXU, or a TXU and TCU TX System.
For a summary of settings that can be changed using the front
panel Control Switch and which are made using the STRATA TX
Configurator software, see “Front Panel vs. STRATA TX
Configurator Settings” on page 3-34.

The STRATA TX is designed to enable you to control operating
settings through Presets stored in the transmitter. The STRATA
TCU and TXU are shipped with factory Presets and can be
customized for the user.
Your STRATA TX System can be pre-configured with up to 9
Presets. Each Preset contains most of the operating settings
needed to control the STRATA TX System. System Presets can
only be defined and changed using the STRATA TX Configurator
software. Presets cannot be changed from the TXU or TCU front
panels.
For information on configuring Presets, see the “Configurator
Reference” Appendix on page C-1 (part of the STRATA TX
Technical Reference Manual only).
Notes
When you change a Preset, the new Preset
remains in effect. When the TX System is powered
down, that Preset is active when the TX System is
powered up again.

TCU via the coaxial cable from the TXU.
Note
Apply DC Power on Coax
2.
Figure 3-32: Main Screen
Preset 3
When the TCU and TXU are mounted in separate
locations, it is recommended that DC input power
be connected to the TXU.
Since either unit may be powered from the other
unit via DC power superimposed on the coaxial
cable between the units, DC input power may
therefore be applied to either the TXU or the TCU.
If your TXU and TCU configurations contain DC ON COAX
switches mounted on the units, these switches must be set to
ON in addition to controlling DC power superimposed on the
coaxial cable from the TXU to the TCU or from the TCU to the
TXU.
To apply DC power from the TXU to the TCU superimposed on
the coaxial cable between the two units, perform the following
steps.
Verify the STRATA TX System is connected and
powered up. See ”Powering the STRATA TX System”
on page 3-12.
Observe the Main Screen (Figure 3-32) is displayed.
