2.2 System Description
The MRX4000 (Figure 2-1) is a highly reliable, flexible, and
compact video microwave central receiver system with
demodulation and decode functions for fixed installations. The
MRX4000 is mounted in a standard 19-inch (48.3 cm) rack for
fixed site operations.
Figure 2-1: MRX4000
The MRX4000 is used with existing MRC CodeRunner 4 (CR4)
receivers in analog and digital Electronic News Gathering (ENG)
central receive site operations. The unit allows operators to
switch between analog and digital modes where both
applications are used. The MRX4000 also provides separate
video and audio or broadband composite operation.
Key features of the MRX4000 are as follows:
• Analog, Digital, or Analog/Digital switchable
• FMR receiver demodulation technology (analog)
• COFDM demodulation and MPEG decoding technology
(digital)
• Digital demodulation for QPSK, 16QAM, and 64QAM
• IF (70 MHz) signal input and monitoring for demodulation

Product Description 2-2MRX4000 Operator’s Guide/Tech Ref Manual
• ASI signal output connection interfaces
• SDI signal output connection interfaces
• Video and audio outputs for NTSC or PAL video/audio
signal transmission
• Front panel keypad and display operation and control
• Serial communication interface for remote control and
management
• System configuration control and management via the
MRX4000 Configuration Utility software
• Multiple configuration options available
• Lightweight, modular, multi-unit designs
2.2.1 Configuration Options
MRC is constantly working to expand and upgrade the
capabilities of the MRX4000. Consult your Sales Representative
or contact the factory for the latest information.
The MRX4000 is currently available in the following
configurations:
• MPEG/COFDM/FMR NTSC - Digital/Analog
• MPEG/COFDM/FMR PAL - Digital/Analog.
• FMR NTSC - Analog Only
• FMR PAL - Analog Only
• MPEG/COFDM - Digital Only
If the MRX4000 contains the analog FMR module, the module
will be be factory-configured for either NTSC or PAL operation
and cannot be changed by the user. If the MRX4000 contains
the digital MPEG/COFDM modules, no factory or user changes
are required to configure the digital modules for NTSC or PAL
operation.
2.2.2 Configuration Descriptions
General The front panel of all configurations of the MRX4000
(Figure 2-2) contains a POWER LED, an ALERT LED, an
ALARM LED, an alphanumeric display, and six function
switches. The front panel also contains an RS-232 connector,
located behind an access cover, to provide interface connections
to a Windows-based PC.
Figure 2-2: MRX4000 Front Panel View
The rear panels of the various MRX4000 configurations contain
the I/O connectors, the input power connector, the power switch,
and a fuse.
Controls, indicators, and connectors contained on all
configurations of the MRX4000 are identified and described in
the “Routine Operation” Chapter on page 3-1.
Configurations The rear panels of the Digital and Digital/
Analog MRX4000 MPEG, MPEG/COFDM/FMR NTSC, and
MPEG/COFDM/FMR PAL configurations are identical and are
shown in Figure 2-3 on page 2-3.
The rear panels of the Analog MRX4000 FMR NTSC and FMR
PAL configurations are identical and are shown in Figure 2-4 on
page 2-3.

2.2.3 Power Options
The flexible architecture of the MRX4000 allows the various
configurations to operate on the following AC and DC power
sources:
• 120/240 VAC, 50/60 Hz
• +24 or +48 VDC
• -24 or -48 VDC
Fuse ratings for the optional AC and DC power sources are
listed in Table 2-1.
Refer to the “ Installation” Chapter on page 6-1 (part of the
MRX4000 Technical Reference Manual only) for additional
information.
2.2.4 Mounting and Deployment Options
The MRX4000 is mounted in a standard 19-inch (48.3 cm) rack
for fixed site operations.
For more details on installation of the MRX4000 in various
applications, see the “ Installation” Chapter on page 6-1 (part of
the MRX4000 Technical Reference Manual only).

2.2.5 System Integration
System Operation The MRX4000 offers two levels of system
configuration, designed to match the needs of different
personnel.
For the field operator, the MRX4000 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 front panel-controlled settings are dependent
upon the options contained in the MRX4000. See ”Using the
MRX4000 Screens” on page 3-8 for additional information.
For the advanced operator and technical staff, the MRX4000
Configuration Utility software allows complete control of all
parameters in the MRX4000. The MRX4000 Configuration Utility
software runs on a Windows-based PC and connects to the
MRX4000 front panel RS-232 connector via an RS-232 serial
interface cable.
Interfacing a PC to the MRX4000 in a connected system gives
you complete control of the unit. You can read the current
settings, program new settings, or return the unit to its factory
default settings. The MRX4000 Configuration Utility software
automatically detects what hardware is installed in the system
and applies the appropriate configuration, regardless of the
hardware being configured.
