General Safety Information
The following safety requirements, as well as local site
requirements and regulations, must be observed by personnel
operating and maintaining the equipment covered by this manual
to ensure awareness of potential hazards.
Notices
Notices-i
WARNING - RF Power Hazard
Note
High levels of RF power are present in the unit. Exposure to RF
or microwave power can cause burns and may be harmful to
health.
Remove power from the unit before disconnecting any RF cables
and before inspecting damaged cables and/or antennas.
Avoid standing in front of high gain antennas (such as a dish
antenna) and never look into the open end of a waveguide or
cable where RF power may be present.
RF Exposure - Safe Working Distances
MRC provides this warning for safety purposes with the intent to
inform the user of the potential hazard of RF exposure. The
following guidelines for safe operation were derived from OET
bulletin 65, August 1997, as recommended by the Federal
Communications Commission (FCC).
The PTX-PRO 13 GHz Transmitter is a mobile transmitter
system designed to provide services to broadcast ENG users
under CFR 74 subpart F and 74.601 TV pickup stations. This
unit, operated without an antenna, will not create RF energy
exceeding 1.0 mW/cm2, the FCC limit for exposure. Once
connected to an antenna, the potential for harmful exposure will
be greatly enhanced.
In this situation, a certain distance from the radiator is to be
maintained. Calculations need to be performed to understand
what that safe margin for exposure is. This is known as the
Maximum Permissible Exposure (MPE) limit.
Hazardous RF radiation limits and recommended
distances may vary by country. Ensure that all
applicable state and federal regulations are
observed when using this transmitter.
Calculations provided are for common antennas often utilized in
the ENG environment. The following formula used is that
suggested by OET 65.
Calculating MPE
EIRP = P * (10 ^ (G / 10)) = (antilog of G/10) * P
P = RF power delivered to the antenna in mW
G = Power gain of the antenna in the direction of interest relative
to an isotropic radiator
R = distance to the center of radiation of the antenna in
centimeters
S = MPE in mW/cm² (milliwatts per square centimeters)
Conversions
dBi to numeric gain = Antilog (dBi/10)
Feet to centimeters = Feet * 30.48
Centimeters to Feet = cm * .0328
4 π = 12.57
User Input
RF power delivered to the antenna = Watts
Antenna gain (referenced to isotropic antenna) = dBi
Distance from the center of radiation = Feet

PTX-PRO Monitoring Operations
The PTX-PRO Presets are set to five possible modes of
operation. These operating modes are established using the
Configurator software. Operating mode options displayed on the
Monitor screens are indicated below in bold fonts. Operating
mode options available via the Configurator software are as
follows:
•
MPEG/COFDM IF Out (COFDM mode)
•
COFDM Only - ASI In (ASI/SDI In mode)
•
External 70MHz IF In (Ext IF Input mode)
•
LMS-T (Terrestrial) (LMS-T mode)
Once the PTX-PRO is set up and powered up, you will be able to
check its configuration and monitor its operation. When
configuration settings are established for the individual Presets
using the Configurator software, the individual Preset operating
modes should be recorded for quick reference.
The following sections describe how to use the Monitor screens.
Here are the tasks described:

System Rules
CAUTION
Do not make any configuration changes to
your PTX-PRO while the PTX-PRO is
connected to a radio system that is actively
transmitting.
Attempts to program configuration changes
into a PTX-PRO when the radio system is
actively transmitting will interrupt broadcast
operations.
When configuring your PTX-PRO on-line (connected to a PC), the
following system rules must be followed.
•
When the PTX-PRO is properly connected to your PC and
the system is powered up, the Configurator software will
automatically detect your PTX-PRO, your hardware
configuration, and the licensed options contained in your
PTX-PRO.
•
The PTX-PRO must be powered up prior to initializing the
Configurator software.
•
The configuration settings can be saved to the PTX-PRO or
can be saved to a file and can be recalled at a later date.
•
Configuration settings may be loaded into the Configurator
from your PTX-PRO, may be modified, and may be loaded
into your PTX-PRO and/or saved to a file in the on-line
mode.
•
The PTX-PRO must not be placed in the transmit mode
when utilizing the Configurator software.
•
Channel plans may be created in the on-line mode or in the
offline mode. Channel plans created in the offline mode
PTX-PRO User and Technical Manual
•
Channel plans may be loaded into the Configurator from
your PTX-PRO, may be modified, and may be loaded into
your PTX-PRO and/or saved to a file in the on-line mode.
•
PTX-PRO configurations and channel plans may be
created or modified from a file on your PC in the on-line
mode.
•
When selecting options in the on-line mode, if the option
is a licensed option that is not contained in your radio, the
option may not be displayed, e.g., if you do not have the
LMS-T licensed option in your radio, the LMS-T tab will
not be present on the Configurator.
•
In certain instances, licensed options may be displayed
on a Configurator page, but if your radio does not contain
the licensed option, the option will be inactive, you cannot
select the option, and you cannot load the option into your
radio.
The procedures required to create or update configurations and/
or channel plans are provided in the following sections.
5.2.5
Configurations
New configurations can created from scratch, updated from
existing files on your PC, or may be loaded in from a PTX-PRO
and modified. Once a configuration is created or modified and
saved, you can load the configuration into your PTX-PRO. The
steps required to load configuration changes are provided in the
applicable procedures.
Once a configuration is created or modified, it should be saved to
a file on your PC. The steps required to save configuration
settings are provided in the applicable procedures provided in
this Chapter.

Channel Plans
New channel plans can be created from scratch, updated from
existing files on your PC, or may be loaded in from a PTX-PRO
and modified. Once a channel plan is created or modified and
saved, you can load the channel plan into your PTX-PRO. The
steps required to load channel plan changes are provided in the
applicable procedures provided in this Chapter.
Once a channel plan is created or modified, it should be saved to
a file on your PC. The steps required to save channel plan
settings are provided in the applicable procedures.

Create or Update a Configuration
There are various ways to create or modify a configuration online with the PTX-PRO connected to a PC via an RS-232 link.
accessed through the MRC Radio Configurator icon displayed
on your PC desktop.
The settings are grouped into pages according to function. The
pages are accessed using tabs. Pages also contain option
buttons, pull-down menus, text boxes, radio buttons, and check
boxes to select or activate different functions and options.
Procedures contained in this Chapter utilize easy-to-use
flowcharts to navigate through the various procedures. The
procedures allow use of the Configurator in the on-line mode
with the Configurator software connected to the PTX-PRO via an
RS-232 interface.
5.3.2
Determine Licensed Options
•
Create a configuration on-line.
Prior to preparing or modifying any PTX-PRO configuration
settings in the offline mode, you must determine what licensed
options are contained in your PTX-PRO.
•
Load in an existing configuration from a file and modify it
on-line.
If you have not previously recorded your PTX-PRO licensed
options, you must perform this procedure.
•
Load in a configuration from the PTX-PRO and modify it.
•
Load and modify individual configuration pages.
•
Once a configuration is created and saved to a file on
your PC, the configuration file can be loaded into the PTXPRO.
In order to determine the licensed options contained in your
PTX-PRO, you must connect your PTX-PRO to the Configurator
software via an RS-232 link to your PC. When your PTX-PRO is
powered up and is connected to the Configurator in the on-line
mode, the Configurator software automatically detects the
licensed options contained in your PTX-PRO.
Each of these methods is explained in detailed steps in the
following sections.
5.3.1
Using the Configurator Software
The MRC Radio Configurator software has an easy-to-use
Graphical User Interface (GUI) to access Preset configuration
settings and channel plan settings. The Configurator software is
PTX-PRO User and Technical Manual
After determining what licensed options are contained in your
PTX-PRO, you must record the options. You can then
disconnect from the Configurator software and can prepare
configuration settings in the offline mode without having your
PTX-PRO connected to your PC and the Configurator software.
The flowchart required to determine the licensed options
contained in your PTX-PRO is contained in Figure 5-1 on

Multipurpose Data Cable
In order to access both radio and Wayside data, you need to use
a Multipurpose Data Cable. The cable and wiring diagram are
shown in Figure 6-17 on page 6-16. If necessary, the
Multipurpose Data Cable may be ordered from MRC.
The Multipurpose Data Cable contains two DB-9 female
connectors and one DB-9 male connector. The Multipurpose
Data Cable contains band markers indicating connections to
HOST, WAYSIDE, and RS-232 connectors. The Multipurpose
Data Cable DB-9 female RS-232 connector is connected to the
PTX-PRO RS 232 connector.
The HOST DB-9 male connector is configured as a Data
Terminal Equipment (DTE) device connector for connection to a
PC or laptop PC. When connected to a DTE device, a null
modem cable must be connected between the DTE device and
the Multipurpose Data Cable DB-9 HOST male connector. If
connected to a Data Communications Equipment (DCE) device,
a null modem cable cannot be used, but a straight pin-to-pin
extension cable will be required.
The WAYSIDE DB-9 female connector is configured as a DCE
device connector for connection to a modem, GPS, etc. When

connected to a DCE device, a null modem cable must be
connected between the DCE device and the Multipurpose Data
Cable DB-9 female WAYSIDE connector. If connected to a DTE
device, a null modem cable cannot be used, but a straight pin-topin extension cable will be required.
•
This cable is needed to connect to the PTX-PRO data
connector (DB-9) on one end and connect to the device
server on the other (a DB-25 connector in the case of the
UDS-10).
Null modem cables may be obtained from MRC or any computer

Theory of Operation
8-1
All PTX-PRO configurations are available with Standard
Definition (SD) or SD and optional High Definition (HD) video
technologies.
The PTX-PRO can accept a wide variety of signal formats and
includes an RF up-converter for use in transporting signals over
a microwave link. The PTX-PRO also contains an MPEG/
COFDM module.
The PTX-PRO contains a universal power supply and can
operate on 90 to 264 VAC, 50/60 Hz or +11.0 to +36.0 VDC.
8.3
Command and Control Power Supply
The PTX-PRO command and control power supply modules
contain external and internal communications circuitry, as well as
supplying necessary system voltages.
The PTX-PRO power supply accepts a wide range of DC input
voltages (+11.0 to +36.0 VDC) or 90 to 264 VAC, 50/60 Hz. The
supply converts the input voltage to the DC voltages required by
the rest of the PTX-PRO circuits and distributes the appropriate
output voltages to the various circuits.
The on-board microprocessor manages the system configuration
and operation of all modules to which it is connected, e.g.,
MPEG/COFDM, IF/RF modules, etc.
System Theory of Operation
The PTX-PRO is comprised of the following primary
components:
•
Command and control universal power supply module
•
MPEG encoder/COFDM modulator module
See Figure 8-2 on page 8-3 for a block diagram of the 13 GHz
PTX-PRO.
The PTX-PRO also contains the IF/RF module which accepts
either a 70 MHz COFDM or external 70 MHz input signal and upconverts these signals to the 13 GHz RF band. The PTX-PRO
can therefore serve as a standalone digital video microwave
transmission system.
The RF frequency synthesizer circuit included in the IF/RF
module, along with the command and control module, provide
the means to channelize RF video and audio signals in the 13
GHz RF band. Standard U.S. FCC band plans, as well as
custom channel plans, may be accommodated using the MRC
Radio Configurator (Configurator), when the Configurator
software is connected to the PTX-PRO.
PTX-PRO User and Technical Manual
8.3.1
This ensures that the PTX-PRO can permit switching modes of
operation, change system Presets, etc. Therefore, system
control may be accomplished using front panel control or remote
control.
8.3.2
MPEG/COFDM Encoder/Modulator Module
The MPEG/COFDM module is the heart of the PTX-PRO digital
mode circuitry. This circuit may be configured to accept a wide
range of digital or analog video and audio signal inputs and
provide COFDM IF (70 MHz) video signal outputs.
The various signal inputs and outputs are connected through the
PTX-PRO combiner circuit where they are switched under
software control.
