1.6 System Description

The DRS2000HS/DRS6000HS Digital Diversity Receiver (Figure

1-1) is a high performance, cost-effective COFDM receiver suit-

able for public safety, government, and homeland security opera­tions. The receiver is an ideal choice for applications that require
hands-off antenna diversity.

Figure 1-1 DRS2000HS/DRS6000HS Receiver - Typical

The receiver consists of a 2RU high, rack-mountable, digital
microwave receiver that supports either two or six antenna
inputs. All functions can be operated from the front control
panel.
The receiver uses the latest maximal ratio combining (MaxRC)

technology to optimize the quality of the transmitted signal. The
receiver supports Coded Orthogonal Frequency Division
Multiplexing (COFDM) demodulation, and MPEG decoding in
standard definition (SD).

The receiver operates on 100 to 260 VAC at 50 to 60 Hz. An
auto-sensing circuit detects actual line voltage.

You can readily monitor current settings with the front control
panel or change system parameters using the keypad and the
control panel. Frequently used settings can be saved in one of
50 presets. A video monitor offers a display of live video.

Introduction 1-3DRS2000HS/DRS6000HS User and Technical Manual

In a typical system, each antenna is connected to a separate
low-noise block downconverter (BDC) by a short cable or direct
N-Type connector. The converters output a UHF signal through
coaxial cable to UHF input ports at the rear of the receiver. The
receiver and downconverters may be separated by up to 600
feet (183 m), depending on frequency and cable type.

Incoming signals and downconverter power travel on the same
cable using BiasT interfaces in both the converter and the
receiver. The receiver samples the signal-to-noise ratio (SNR)
from all antennas, constructing an optimized signal from one or
more signals. High quality RG-6 or RG-11, 75-ohm coaxial cable
should be used to connect the receiver and downconverters.

The COFDM demodulator and SD MPEG decoder support
standard Digital Video Broadcast-Terrestrial (DVB-T) 2K
operation.

A typical configuration is shown in Figure 1-2 on page 1-4.

1.7 Features

The receiver offers the following features:

• Two antenna inputs (DVB-T, DRS2000HS Receiver only)

• Up to six antenna inputs (DVB-T, DRS6000HS Receiver
only)

• Maximal ratio combining (MaxRC) diversity technology

• Supports DVB-T demodulation technology

• Front panel live video monitor

• Real-time front panel monitoring for Signal-to-Noise
(SNR), Link Quality signal integrity (LQ), Receive Carrier
Level (RCL), and Bit Error Rate (BER)

• Embedded real-time operating system accessible via

front panel control screen

• Up to 50 programmable presets (saved settings) using the
receiver control panel

• Rack Mountable, compact EIA 19-inch rack, 2 RU height

• Supports 6, 7, and 8 MHz COFDM/DVB-T pedestals

• Internal web server for remote management via a
networked computer

• Band plans can be customized

• Compatible with MRC and Link Research low-noise block
downconverters. See “Block Downconverter Options” on

page 1-6 for options.

1.8 Hardware Components

A typical installation consists of a receiver, low-noise block
downconverters, filters, antennas, and cables.

1.8.1 Receiver

The DRS2000HS accepts 2 antenna inputs and the DRS6000HS
accepts 6 antenna inputs. Both receivers incorporate MaxRC
diversity technology, COFDM demodulation, SD MPEG
decoding, and DVB-T demodulation mode. With a front panel
video monitor and control screen, the receiver takes up only 2
RU of space in a 19-inch rack. The receiver can be operated
locally or remotely via a master controller.

The base model includes:

• 2- or 6-input receiver

MRC offers several types of antennas. See “Antenna Options”

on page 1-6 for more information.

1.8.3 Low Noise Block Downconverters

The receiver is compatible with several MRC and Link Research
downconverters (BDCs) that transform the incoming RF signal
into UHF for input to the receiver. See “Block Downconverter

Options” on page 1-6 for more information.

1.9 Firmware Components

The receiver is controlled by software installed on programmable
read-only memory (PROM). You can access this firmware via
the front control screen, and use it to monitor the incoming signal
and control settings such as channel, frequency, and RF band.

The firmware also provides a web server that you can access
from a PC or laptop computer as long as both the receiver and
the computer are connected to the same Local Area Network
(LAN). See “Routine Operation” on page 2-1 for more
information.

1.10 Frequency Bands

The receiver can operate in one of several factory-set frequency
bands: 2, 3, 4, 5, 6, or 7 GHz. The operating frequencies are

provide access to system parameters and settings. See

“Keypad Operation” on page 2-6 for details.

2.2.2 Rear Panel Connectors

The rear panel contains the connectors for power, diversity
inputs and outputs, and audio outputs.

The rear panel provides numerous inputs to and outputs from the
receiver. These inputs and outputs are as follows.

BDC 1 thru BDC 6 Connectors The TNC block
downconverter (BDC) connectors accept UHF signals from the
downconverters and their corresponding antennas. BDC 3 thru
BDC 6 connectors are not contained on the DRS2000HS
Receiver.

To power each downconverter, +18.5 VDC is applied to the
coaxial cable that runs from the BDC connector to the
downconverter.

WAYSIDE DATA Connector The WAYSIDE DATA, 9-pin
female connector is used for transfer of data such as global
positioning satellite (GPS) data or metadata from the MPEG
decoder. By using a standard RS-232 cable, the receiver’s
WAYSI DE DATA connector can be connected to a computer or
an auto-tracking antenna system.

ALARM Connector The ALARM DB-15 female connector
connects to single-pole single throw (SPST) switches for
summary alarm data for common faults and events and for site
management control. One SPST switch is for a minor alarm,
one SPST switch is for a major alarm, and four SPST switches
are for site management.

ASI OUT Connector The ASI OUT, 75 ohm, female BNC
connector provides ASI outputs for digital video and audio
distribution.

CV 1 and CV 2 Connectors The Composite Video CV 1 and
CV 2, 75 ohm, female BNC connectors provide analog video

signals.

AUDIO 1 and AUDIO 2 Connectors The AUDIO 1 and
AUDIO 2 connectors provide analog audio outputs and digital
audio outputs on Audio 2 when digital mode is selected.

is used to remotely control the DRS2000HS/DRS6000HS via a
slave controller.

Routine Operation 2-4DRS2000HS/DRS6000HS User and Technical Manual

POWER Connector The POWER connector provides the AC
input power to the unit. An auto-sense circuit accepts either 110
to 130 VAC or 205 to 240 VAC @ 2 amps.

2.3 Preparing for Operation

The procedures required to operate the DRS2000HS/
DRS6000HS receiver are contained in the following paragraphs.
The color LCD Control menu and the keypad are used to control
all features of the receiver.

2.3.1 Installation

The DRS2000HS/DRS6000HS receiver is typically mounted in a
19-inch (48.3 cm) rack. The unit and cabling are permanently
installed and power comes from facility power.

For additional information, refer to the “Installation” Chapter on

page 4-1.

2.3.2 Powering the Receiver

The following paragraphs provide steps to power up and power
down the receiver. If the receiver is installed at an unattended
central receive site, then it typically stays powered up for
extended periods of time.

When the power switch is set to on ( I ), the video monitor will
initially display a blank screen and the Control menu will display
color bars, a logo screen, and finally the Control menu. The
settings displayed when the Control menu is displayed will be the
settings in effect when the unit was last powered down.

Power Up

To power up the receiver, perform the following steps.

1. Verify that the power cable is connected to the

POWER connector on the rear panel of the receiver
and is connected to an AC power source.

2. Verify that all coaxial cables and cable connectors are

properly connected to the front and rear panel
connectors, as required.

3. Verify that the AC power source is turned on.

Note

When power is set to on in the following step, the
settings displayed will be those in effect when the
receiver was powered down.

If there is no incoming signal, the RCL, SNR, and
Link Qual indicators will display their lowest values or
no values.

For a DRS6000HS Receiver with six incoming
signals, the RCL, SNR, and Link Qual indicators
alternate between the A-B-C-D inputs and the E-F
inputs.

4. Set the power switch on the front panel to on ( I ).

- The video monitor displays a blank screen.

- The Control menu goes through a power-up cycle

consisting of color bars, a product ID screen, and
finally the initial Control menu, as shown in Figure 2-2

on page 2-5.

Figure 2-2: Initial Control Screen - Typical

Powering Down

To power down the receiver, perform the following steps.

1. Verify the Control menu is displayed.

2. Set the power switch on the front panel to off ( O ).

2.4 Control Menu Operations

The Control menu is displayed on the LCD color monitor and
provides access to receiver functions. This menu provides the
graphical user interface (GUI) access to the settings and
functions of the receiver.

When you operate the receiver via the Control menu, you can
monitor Receive Carrier Level (RCL), Signal-to-Noise Ratio
(SNR), and Link Quality for all incoming video signals. You can
also change receiver settings such as channel, frequency, and
RF band, and save them as presets, as needed.
