Overview
Avoid Potential Operational Problems
Information contained in the following paragraphs identify potential problems that can be avoided by reading and following the operating procedures provided in this manual.
To avoid potential operational problems, please review the information contained in the “Routine Operation” Chapter on
page 3-1. The Routine Operation Chapter cont ains step-by-step
procedures that, when performed correctly, will eliminate potential problems that could be caused by operator error or by lack of experience with the MTX5000 system.
Radio Unable to Transmit or Gener ally Unstable
If the radio is unable to transmit or is generally unstable, perform “Select Preset” on page 3-24 to select or re- select the proper Preset. Then verify proper transmitter operation by tran smitting and receivin g.
If the radio remains unstable, it may be necessary to cycle power off and on. See ”Powering the MTX5000 System”
on page 3-7 to power down and power up the MTX5000.
Always wait a minimum of 10 seconds between powering the radio down and then powering the radio up again.
After cycling power to off and back to on, perform “Select
Preset” on page 3-24 to sele ct the proper Preset. Then
verify proper transmitter operation by transmitting and receiving.
If the radio is still unable to transmit or remains unstable, contact MRC Technical Support for assistance.
Improper Power Up/Power Down
If the radio is unable to transmit, is unstable, or if the software appears to be corrupted, the Preset may have been selected or changed too soon after power was applied or the wrong Preset was selected.
Always wait a minimum of 5 seconds after the Main screen is displayed following power up before selecting a Preset.
If the wrong Preset is selected, you must wait a minimum of 5 seconds before attempting to select another Pr eset. Failure to wait 5 seconds minimum between Preset selections will cause software hang-ups.
If the radio is unable to transmit, is unstable, or if the software appears to be corrupted, power to the radio may have been removed and reapplied too quickly.
The MTX5000 central processor requires a minimum of 10 seconds to properly shutdown to avoid possible software corruption.
NOTE TO USER iiMTX5000 User and Technical Manual
Software corruption can occur if the external input power to the radio was momentarily lost and was then reapplied without waiting a mini mum o f 10 seconds betw een lo ss of power and reapplication of input power.
The problem may also occur if the power switch was pressed to off and back to on without waiting a minimum of 10 seconds.
To avoid problems, always wait a minimum of 10 seconds between removal or loss of power and reapplication of power to the radio.
The problem may also occur if the progress bar was displayed when power was removed from the radio.
Always ensure the progress bar is not displayed on the color LCD display panel when power is removed from the radio.
If this problem has occurred, press the power switch to off, wait 10 seconds minimum, and press the power switch to on. The internal processor will attempt to perform a self-recovery of the software.
During the software recovery attempt, a progress bar will be displayed on the color LCD display panel indicating the progress of the process. This progress bar will take more time to reach 100% tha n during a normal power up.
Do not become impatient during the software
recovery process due to the time it may take for recovery. Do not remove and reapply power while the progress bar is displayed during the software self­recovery process. Software corruption will occur!
When the power up is complete and the Main screen is displayed on the color LCD display panel, verify proper transmitter operation by transmitting and receiving.
If the software is corrupted and the Main screen is not displayed, contact MRC Technical Support for assistance.
Radio State Incorrect
If the radio state is incorrect, the correc t Preset may not have been selected. Select the proper Preset per “Select Preset” on
page 3-24.
PA Voltage Adjust Setup Software H ang-up
When performing “Perform PA Voltage Adjust Setup” on page 3-
44, ensure the Outdoor Unit (ODU) is properly connected to the
IDU. If the ODU is not connected to the IDU and you attempt to perform this procedure, the software will hang up.
To avoid software hang-up, alway s ensure the ODU is
connected to the IDU when performing the P A V oltage Adjust Setup procedure.
Check the Main screen ODU status indicator. If a major fault exists in the ODU, do not perform the PA Voltage Adjust Setup procedure until the fault has been corrected or until the ODU is connected to the IDU.
If the ODU is not connected to the IDU or if the ODU has suffered a failure, the PA Voltage Adjust Setup Screen will remain displayed on the co lor L CD di splay p anel if th e PA Voltage Adjust Setup screen Start option button is selected.
If the software hangs up due to the ODU not being connected to the IDU or if the ODU has failed, perform the following:
Press the power switch to off.
Connect the ODU to the IDU or go to “Troubleshooting”
on page 4-1 to correct the fault.
NOTE TO USER iiiMTX5000 User and Technical Manual
Press the power switch to on, perform “Select Preset” on
page 3-24 to select the proper Preset.
“Perform PA Voltage Adjust S etup” on p age 3-44 and then verify proper transmitter operation by transmitting and receiving.
RF Levels Too High
If the transmitted RF levels are too high, “Perform RF Level
Adjust” on page 3-49.
Software Recovery
If the software becomes corrupted, the MTX5000 IDU will attempt to self-recover the software. During the software self­recovery, the previously configured parameters may be recovered - not the latest p aram eters. This may ha ppen i f a fau lt occurs when installing software up dates.
If the software becomes corrupted, press the po wer switch to off, wait 10 seconds minimum, and press the power switch to on. The internal processor will attempt to perform a self-recove ry of the software.
During the software recovery attempt, a progress bar will be displayed on the color LCD display panel indicating the progress of the recovery process. This progress bar may take considerably m or e ti me to reach 100% than during a normal power up.
Do not become impatient during the software recovery process due to the time it may take for recovery. Do not remove and re apply power while the progress bar is displayed during the software recovery process. Software corruption will occur!
When the power up is complete and the Main screen is displayed on the color LCD display panel, you may need
to perform “Select Preset” on page 3-24. Then verify proper transmitter operation by transmitting and receiving.
If the software is no longer corrupted, perform “Firmware
Update” on page 5-114 to verify that you have the latest softwar e
installed in your MTX5000 IDU. Update the software, as required.
If the software is corrupt ed o r i f the Ma in sc reen is not displ ayed, contact MRC Technical Support for assistance.
Color Bar Generator Operations
All MTX5000 Indoor Units (IDU) contain a built-in digital Color Bar Generator (CBG) as standa rd equipment. The IDU is also available with an optional analog CBG. Potential operator problems can occur when using the optional analog CBG or the built-in digital CBG.
Potential operator-induced problems may include the following:
Selection of the CBG On operating mode during test, troubleshooting, or CBG setup and failure to select the Off, A Gen, or A Stby operating mode for normal operation when test , troubleshooting , or CBG setup is completed.
Selection of the CBG On, A Gen , or A Stby operating mode when the optional Analog Color Bar Generator is not installed in the MTX5000 IDU.
To avoid potential operator problems that can impact operation of the MTX5000 System, the following information is provided:
The optional analog CBG and the digital CBG both include Off, On, A Gen (Auto Generated), or A Stby (Auto Standby) operating mode options.
The CBG mode should only be set to the On operating mode for test, troubleshooting, or for setup of the
NOTE TO USER ivMTX5000 User and Technical Manual
applicable Color Bar Generator.
During normal operation, the CBG Off, A Gen, or A Stby operating mode must be selected for proper operation and video transmission.
CBG operating modes are not Preset-specific or mode­specific. If your IDU contains the optional analog CBG and you select the Off, A Gen, or A S tby oper atin g mod e for an analog Preset, the selected option is applicable for all analog Presets, as well as for all digital Presets.
If the CBG On operating mode is selected, the output of the MTX5000 IDU will be color bars only, not video, regardless if an analog or a digital Preset is selec ted.
When color bars are set to On (enabled), color bars take priority over all analog and digital Preset settings.
If the IDU output consists of color bars only, please verify that the analog and/or digital CBG operation mode is not set to On before you call customer service. The problem may be nothing more than having selected the On operating mode.
Perform “Select Color Bar G enerato r Mode ” on p age 3-52 to select the Off, A Gen , or A Stby operating mode.
It is possible to select analog CBG options if you do not have the optional CBG installed in your MTX5000 IDU, but the options are not active and will result in transmission problems.
Be careful when setting CBG options if you do not have the optional analog CBG installed.
If you attempt to set the CBG operating mode to On, A Gen, or A Stby and you do not have the optional analog CBG installed in your MTX5000 IDU, you will have a blank
screen displayed for analog Presets. Before calling Customer Service, please verify that the analog CBG operating mode has not been set to On.
Go to “Select Color Bar Generator Mode” on page 3-52 and select the Off, A Gen, or A Stby operation mode.
When utilizing a digital Preset with an ASI video input and the digital CBG option setting is A Gen or A Stb y, loss of the ASI video input will not display color bars or will no t change the MTX5000 IDU operation to standby indicating loss of the ASI signal. This is normal operation for ASI video loss.

General Safety Information
The following safety requirements, as well as local site requirements and regulations, must be observed by personnel operating and maint aining the equi pment covered by t his manual to ensure awareness of potential hazards.
WARNING - RF Power Hazard
High levels of RF power a r e pr e sent in the unit. Exposure to RF or microwave power can cause burns and may be harmful to health.
Remove power from the unit before discon necting 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 presen t.
RF Exposure - Safe Working Distances
MRC provides this warning for safety purposes with the intent to inform the user of the potential hazard to 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 MTX5000 Transmitter System 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 en ergy
exceeding 1.0 mW/cm2, the FCC limit for exposure. On ce connected to an antenna, the potential for harmful exposure will
be greatly enha nced. In this situation, a certain distance from the radi ato r is to be
maintained. Calculations need to be performed to understand what that safe margin for exposure i s. This is known as the Maximum Permissible Exposur e (MPE) limit.
Note
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 t he anten na i n th e dir ectio n of inte rest relati ve 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
Notices Notices-iiiMTX5000 User and Technical Manual
User Input RF power delivered to the antenna = Watts Antenna gain (referenced to isotropic antenna) = dBi Distance from the center of radiation = Feet
Calculation steps:
1. [P] RF power input. Convert watts to milliwatts = Watts * 1000
2. [G] Antenna gain dBi. Conver t to numeric gain = Antilog (dBi/10)
3. [EIRP] Multiply P * G
4. [R] Convert centimeters to feet = Centimeters * .0328
5. Square R
6. Multiply R² * 4π
7. [S] Divide (R² * 4π) into EIRP
S = Power Density in milliwatts per square centimeters. Note: At frequencies above 1500 MHz, S must not be greater than 1.
Reference FCC OET Bulletin 65, August 1997 - Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Fr equency Electromagnetic Fields The examples shown in Figure 1 and Figur e 2 are typical gra phs
for an MRC STRATA Transmitter and show the permissible exposure distance for various antennas. Graphs and data will vary, based on the actual transmitter, output power, frequency, and antenna utilized. One plot provides the permissible ou tput of the transmitter for di gital modulation, and the other plot for analog modulation.
MRC, in accordance with the requ ireme nt s set for th by the FCC , provides this information as a guide to the user. It is assumed that the users of this equipment are licensed and qualified to operate the equipment per the guidelines and recommendations contained within the pr oduct user gu id es and in acco rdan ce with any FCC rules that may apply.

The MTX5000 has two mas t-mounted ODU bands available. Consult your Sales Representative or contact the factory for the latest bands available. These ODUs contain integrated RF up­conversion circuitry and high power RF amplifiers for maximum power and signal quality.
With the new demands for digital modulation, the ODUs have been optimized for improved Modulation Error Ratio/Error Vector Magnitude (MER/EVM) performance with COFDM transmission.
2.2.2 MPEG Encoding and COFDM Transmission
The MTX5000 is capable of encoding both Standard Definition (SD) and HD video, depending upon the options contained in your MTX5000 system. Available inpu ts include SD Serialized Digital video (ASI-SDI), HD-SDI, and composite video.
Audio input formats currently include digital AES/EBU and analog formats. Future enhancements will include AC-3 SMPTE-302. The encoder is also cap ab l e of encod i ng an RS­232 signal as Wayside data. The MTX5000 is capable of generating a fully compliant DVB-T compliant outp ut signal. This provides a robust digital link in any hostile transmission environment.
2.2.3 Analog Video Encoding and FM Modulation
When in the analog FM mode, the MTX5000 will accept a standard composite video input. It will also accept analog audio inputs. The FM analog signal is useful when working with older legacy equipment or when an analog transmission is desired.
The MTX5000 IDU communicates with the ODU to set operating frequencies and power levels. This interface is also used for calibration of the ODU power supply and to monitor error conditions.
2.2.4 RF Control
The MTX5000 IDU (Figure 2-1) is designed to accept a variety of external video and audio signals in different digital format streams and analog signals and to pr o v id e a m od ulated 70 MHz IF output.
Figure 2-1: MTX5000 Indoor Unit
The MTX5000 IDU allow s you to switch between analog and digital modes where b oth applications are used. The MTX5000 also provides separate video and audio or baseband composite operations.
Key features of the MTX5000 IDU are as follows:
Switchable Analog or D i gital modes
SD/HD SDI interfaces with multiplexing
Integrated SD/HD MPEG-2/H.264 encoding technologies
FM transmitter modulation technology (analog)
DVB-T COFDM modulation technology (digital)
IF (70 MHz) signal input and monitoring
Video monitoring output
Video and audio inputs for NTSC or PAL video/audio signal transmission
Product Description 2-3MTX5000 User and Technical Manual
Front panel keypad and touch screen display for operation and cont rol
Multiple configuration options available

The IDU connects to the ODU through the wiring harness between the units. The wiring harness contains DC power, 70 MHz IF, and control for all compon ents mounted on the top of the antenna mast. Functions an d control cont ained in th e wiring harness typically include the following:
70 MHz IF, control, and alarms between the IDU and the
ODU
DC power to the ODU
Power and control for an RF switch to select antennas
Power and control for anten na switching fun ctions (band,
polarization, and power)

Power for mast top lights
Control and power for the Pan and Tilt assembly
RF and control for an off-air antenna
Mast top safety sensors for proximity, high voltage, etc.
Since each installation may be different, the harness must be specified for each installation. The harness can be supplied by MRC, or it is often supplied by the van integrator.
2.6 Configuration Options
MRC is constantly working to expand and upgrade the capabilities of the MTX5000. Consult your Sales Representative or contact the factory for the latest information.
2.6.1 IDU Configurations
Your MTX5000 IDU consists of an MPEG encoder, a COFDM modulator, and an analog FMT modu le.
2.6.2 AC Power
The MTX5000 IDU operat es on the following AC p ower:
120/240 VAC, 50/60 Hz
Fuse ratings for the AC power sources are listed in Table 2-1.
Table 2-1: AC Fuse Ratings
Operating Voltage Fuse Rating
120 VAC, 50/60 Hz 3.0A SB 250V 3AG or 5 x 20 mm 240 VAC, 50/60 Hz 1.5A SB 250V 3AG or 5 x 20 mm
AC power is applied to the MTX5000 IDU, which in turn, provides DC power to the ODU via the wiring harness between them .
Refer to the “ Installation” Chapter on page 6-1 for additional information.
2.6.3 Remote Control Options
For portable mobile operations, the MTX5000 system may be controlled using either a Windows-based laptop PC or by the optional Windows-base d Remote Access S ubnotebook PC . See
Figure 2-8.
Figure 2-8: Remote Access Subnotebook PC
Using either PC eliminates the need for a separate panel­mounted remote control panel to control the MTX5000 system.
Product Description 2-8MTX5000 User and Technical Manual
An RJ-45 crossover cable is required for connect ion to either PC for mobile remote control operations.
The MTX5000 system may also be controlled from a Windows­based PC at a remote location. When controlling the MTX5000 system from a remote location, the remote PC is connected to the MTX5000 system via the Ethernet.
To connect Windows-based PCs to the MTX5000 system, see
”Select Local/Remote Operation Mode” on page 3-20. To
connect the optional Windows-based Remote Access Subnotebook PC to the MTX5000 system, refer to the Remote Access Subnotebook PC Operator’s Guide, part number 400573-1, provided with the optional Remote Access Subnotebook PC.
Information and procedures required to control the MTX5000 system for either portable mobil e applications or for remote location operations are provided in “Using the MTX5000 in
Remote Mode” on p ag e 3-60 and “Remote Location Operations” on page 3-67. Procedures required to control the MTX5000
system using either a Windows-based laptop PC, the optional Windows-based Remote Access Subnotebook PC, or a Windows-based PC at a remote location are identical.
2.6.4 Antenna Options
The MTX5000 system is fully compatible with a variety of antennas, including:
MRC ProStar, models
- 2A20 and 2A20SS (2 GHz)
- 7A30 and 7A30SS (7 GHz)
- 2A20/7A30 (dual band 2 & 7 GHz)
- 2A20/7A30SS (dual band 2 & 7 GHz, solid state switching)
MRC Ellipse 2000
MRC OmniPole Omnidirectional.
Switching functions for band and antenna p olarization are controlled from the front panel of the IDU.
If your installation involves more than one antenna, this can be easily accommodated by using an MRC RF Switch. The RF Switch is also controlled from the front panel of the IDU.
2.6.5 Band and Frequency Options
The MTX5000 system is designed to cover one or more bands. It can be ordered as a single-band unit or as a dual-band configuration to cover the following bands.
2 GHz (17 MHz)
2 GHz (12 MHz)
7 GHz Lower.
Band and frequency information is stored in the RFU, which means switching bands after installation is very simple: just plug in the RFU for the new band and the IDU will automatically configure itself for the new band.
Within these bands, channels can be pre-programmed at the factory to match either the U .S. broadcast ch annel p lan or a pl an specified by the customer.
2.7 System Configurations
The MTX5000 system provides several antenna configuration options to transmit using either an omni antenna or a directional antenna, in either single-band or dual-band operation.
