STRATA TX Operator’s Guide/Tech Ref Manual
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.

a standalone mode, if the TXU and TCU are co-located, or if the
TXU and TCU are mounted in separate locations.

Mounting and Deployment Options
The STRATA TX offers a number of options for either mobile or
portable applications.
portable applications.
For more details on installation of the STRATA TX in various
applications, see the
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.

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.

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.

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 panel-
controlled 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.
