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-iDXL5000 User and Technical Manual

DXL5000 System Receiver

Communications Commission (FCC).

This equipment has been tested and found to comply with the
limits for a Class A digital Device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is
operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be
required to correct the interference at his own expense.

DXL5000 System Transmitter

Changes or modifications not expressly approved by MRC could
void the user’s authority to operate the equipment.

WARNING - RF Power Hazard

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.

The DXL5000 Transmitter is 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.

Note

Calculations provided are for common antennas often utilized in
the ENG environment. The following formula used is that
suggested by OET 65.

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.

Calculating MPE

EIRP = P * (10 ^ (G / 10)) = (antilog of G/10) * P

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 to RF exposure. The
following guidelines for safe operation were derived from OET
bulletin 65, August 1997, as recommended by the Federal

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)

Notices Notices-iiDXL5000 User and Technical Manual

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

The examples shown in Figure 1 and Figure 2 are typical graphs
showing the permissible exposure distance for various antennas.
The plots provide the maximum permissible output of the
DXL5000 Transmitter System at 1 Watt and 2 Watts of RF power
for all frequency bands with digital modulation outputs.

MRC, in accordance with the requirements set forth 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 product user guides and in accordance with
any FCC rules that may apply.

Calculation steps:

1. [P] RF power input. Convert watts to milliwatts = Watts *
1000

2. [G] Antenna gain dBi. Convert 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.

Troubleshooting

3.1 Chapter Overview

This chapter describes how to troubleshoot your DXL5000
Digital Microwave System (DXL5000) Transmitter and Receiver.

3.2 Errors/Alarms

Errors detected during normal operation of the DXL5000 System
Transmitter or Receiver will cause the front panel MAJOR
ALARM, MINOR ALARM, or SCM STATUS LED indicators to
turn amber or red to alert you to investigate the problem. See

Figure 3-1.

Figure 3-1: Alarm Indicators- Typical

as major SCM alarm is present.

Individual alarms are shown on the Alarms - Information tab
displayed on your PC or laptop when you are connected to the
rear panel MGMT connector, either directly or via the internet.

Note that alarms presented in this chapter reflect the factory
default alarm Severity and Type settings. The alarm Severity
level and Typ e settings may be changed by performing “Review

Transmitter Alarms” on page 2-16 to change the settings for an

alarm. See Figure 3-2 on page 3-2.

In Figure 3-2 on page 3-2, no alarms are present, the status for
each option indicates OK in green font, and the Summary
Alarm option button label indicates OK with a green
background. If major or minor faults are present, the option
status will indicate Fault in either red or amber font and the
Summary Alarm option button label will indicate Major or Minor
with a red or amber background, respectively.

If the Latch - On option is selected, you are alerted to the fact
that an error has occurred, even if the fault has been corrected.
When the On option is selected, the alarm must be
acknowledged using the Summary Alarm option button to clear
the alarm. If the Latch - Off option is selected, the alarm will
automatically reset when the fault is corrected.

When flashing amber, the MAJOR ALARM LED indicates the
PA is off and the summary alarm relay has tripped; when amber,
a major alarm has been detected but no action has been taken.

When green, the MINOR ALARM LED indicates no alerts are
present; when amber, indicates an alert is present; and when
red, an alert is present and the alert relay has tripped.

When green, the SCM STATUS LED indicates no alarms are
present; when amber, a minor alarm is present; and when red,

4.2 Unpacking

Each DXL5000 System Transmitter and Receiver is shipped
assembled, wired, and factory tested. Each unit is packaged in
appropriate shipping containers.

Here are some tips to help you with unpacking your new
equipment:

• Unpack the equipment carefully to avoid accidental
damage.

• Be sure to locate all parts and accessories.

• Verify that the items shipped agree with those listed on
the packing list.

• DO NOT discard the container(s) or packing material until
you have inspected the equipment and are sure there is
no shipping damage. The container(s) and packing must
be available in the event that a damage claim needs to be
filed with the shipping carrier.

Checks Before Power-Up 4-12

After the equipment is unpacked, we recommend you inspect it
using the following checklist:

• Check for any dents or scratches.

• Check that the equipment is clean and dry.

• Check that no cables or connectors are broken, damaged,
or loose.

Installation 4-1DXL5000 User and Technical Manual

• Check that no front panel LCDs are broken, damaged, or
loose.

• Check that the 4-digit LCD display has not been
damaged.

4.4 Damage in Shipment

Should any damage be discovered after unpacking the unit, use
the following procedure:

Equipment Rack The DXL5000 Transmitter and Receiver each
mount into the mounting rails of a standard 19-inch (48.3 cm)
equipment rack. Each unit occupies 1 rack unit (1RU) of height.

• Make certain the rack and mounting rails are strong and
rigid enough to support the DXL5000 Transmitter and
Receiver and the rest of the equipment in the rack.

• The rack should be securely attached to a solid surface
such as a floor or wall to prevent movement or tipping
over.

• Immediately file a claim with the shipping carrier.

• Forward a copy of the damage report to MRC Customer
Service.

• Contact MRC Customer Service to determine the
disposition of the equipment.

4.5 Installing the DXL5000 System

Each installation or deployment will have its own specific tasks
according to the application and the installed hardware. The
following sections describe mounting and cabling the DXL5000
System Transmitter and Receiver.

The DXL5000 System Transmitter and Receiver are typically
mounted in a standard 19-inch (48.3 cm) rack. The cabling is
permanently installed and power comes from the facility or site
power source.

4.5.1 Site Preparation

The following requirements are designed to make initial
installation easier and to allow room for future access and
servicing.

• Position the rack to allow easy access to the front and
rear of the equipment.

• Be sure to allow room behind the equipment rack for the
many cables required. The cables should not be pressed
against the rear of the equipment when closing doors.
This will stress the cables and may shorten their life.

4.5.2 Mounting the DXL5000 Transmitter and Receiver

Mounting the DXL5000 Transmitter or Receiver into an
equipment rack is easier if one person holds the unit while
another person installs the mounting screws.

WARNING

Follow instructions carefully.

Exercise care to avoid equipment damage
or personnel injury.

1. Lift the DXL5000 Transmitter or Receiver into place,

lining up the mounting holes with the holes in the rack
mounting rails. See Figure 4-1 on page 4-3.

Installation 4-2DXL5000 User and Technical Manual

Figure 4-1: Transmitter/Receiver Mounting - Typical

DXL5000 TX

• Installation should allow adequate air flow around the
equipment. Air flow should be circulated and mixed with
room air, not trapped in a closed space.

General 6-1

DXL5000 Transmitter 6-1

DXL5000 Receiver 6-1

Definition Television (STD), High Definition Television (HDTV),
and Analog Television (ATV) video system networks.

The DXL5000 System provides broadcast high quality digital
format video transmission under Single Carrier Modulation
(SCM) scheme. The System can be configured as either a
simplex or duplex system.

The DXL5000 System consists of a digital microwave
Transmitter and a digital microwave Receiver to provide
microwave digital video or data transmissions.

6.2.2 DXL5000 Transmitter

The DXL5000 Transmitter is a digital mode transmitter that
accepts transport data streams or an external modulated IF
signal. The input data streams are combined and are modulated
onto the IF signal using SCM technology. The modulated IF
signal (or bypassed external IF signal) is then up-converted to
the radio frequency (RF) required and is transmitted through the
antenna.

A functional block diagram of the DXL5000 Transmitter is
provided in Figure 6-1 on page 6-2.
