1. General Information

General Safety Information

To ensure awareness of potential hazards, all personnel concerned with the operation or maintenance of the equipment must study the information that follows, together with local site regulations.

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. Switch off supplies before removing covers or disconnecting any RF cables, and before inspecting damaged cables or antennas.

WARNING: Avoid standing in front of high gain antennas (such as a dish) and never look

into the open end of a waveguide or cable where RF power may be present.

CAUTION: Users are strongly recommended to return any equipment that requires RF

servicing to Vislink.

WARNING- GaAs / BeO Hazard: Certain components inside the equipment contain Gallium

Arsenide and Beryllium Oxide that are toxic substances. Whilst safe to handle under normal circumstances, individual components must not be cut, broken apart, incinerated or chemically processed. In the case of Beryllium Oxide, a white ceramic material, the principal hazard is from the dust or fumes, which are carcinogenic if ingested, inhaled or entering damaged skin.

Please consult your local authority before disposing of these components.

CAUTION: Tantalum Capacitors: When subjected to reverse or excess forward voltage,

ripple current or temperature these components may rupture and could potentially cause personal injury.

CAUTION: This system contains MOS devices. Electro-Static Discharge (ESD) precautions

should be employed to prevent accidental damage.

CAUTION – AC supply connection and protective earth: The MVL-HD3 series control unit is

a Class 1 device and when used with an AC supply must be connected to a protective earth. Failure to provide this earth may result in high voltages on the unit chassis. Installation should always follow local wiring regulations.

The equipment is supplied with an AC supply connector and cord assembly. The wires in

the cord is colored in accordance with the following convention:

Green & Yellow:

Earth (Ground)

Blue

Neutral

Brown

Live

Always ensure that the equipment is correctly connected. Failure to connect the equipment correctly may render protective devices inoperative; if in doubt consult a qualified electrician.

CAUTION: The equipped front panel on/off switch is a standby function only. Some

components remain powered. An AC isolator switch is fitted on the rear panel adjacent to the AC input connector; in normal use, the equipment should be positioned such that this switch remains readily accessible. To be certain that

Page 8

RCD9 Receiver Operators Manual General Information

Issue No: 1 Page: 2

the equipment is isolated from the AC supply; always unplug it from the AC outlet.

Disposal Instructions

WARNING: DO NOT incinerate batteries. Exposing batteries to naked flames or extreme

heat sources can cause them to rupture or explode.

DO NOT dispose of any of the supplied equipment as household waste. The supplied equipment is not biodegradable in landfill sites. For safe disposal of the supplied equipment, take it to your local (council/authority) environmental waste site. For details, contact your local authority/recycling center.

NOTE: In Europe dispose of all equipment in accordance with the European Environmental

directive.

Environmental

CAUTION: The unit is IP0x rated and must be protected from dripping or splashing

water/fluids. When used outdoors, protect the unit using a rain cover.

Health & Safety

Exposure to Non-Ionizing (RF) Radiation/Safe Working Distances

The safe working distance from a transmitting antenna may be calculated from the relationship:

D =

in which D = safe working distance (meters)

PT = transmitter or combiner power output (watts)

GR = antenna gain ratio = anti log (gain dBi ÷10)

w = Maximum allowed power density (watts/square meter)

The RF power density value is determined by reference to safety guidelines for exposure of the human body to non-ionizing radiation. It is important to note that the guidelines adopted differ throughout the world and are from time-to-time re-issued with revised guidelines. For Vislink use, a maximum power density limit (w) of 1w/m² is to be applied when calculating minimum safe working distances. Appendix A refers.

WARNING: Any transmitting equipment, radiating power at frequencies of 100 kHz and

higher, has the potential to produce thermal and athermal effects upon the human body.

To be safe:

a. Operators should not stand or walk in front of any antenna, nor should they

allow anyone else to do so.

b. Operators should not operate any RF transmitter or power amplifier with any of

its covers removed, nor should they allow anyone else to do so.

Maximum RF Power Density Limits

The RF Radiation Power Density limit figure recommended by Vislink is based upon guideline levels published in:

a. IEEE standard C95.1 1999 - IEEE Standard for Safety Levels with respect to

Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.

b. Guidelines for Limiting Exposure to Time-varying Electric, Magnetic &

Electromagnetic Fields (up to 300 GHz) published in 1998 by the Secretariat of the International Commission on Non-Ionizing Radiation Protection (ICNIRP).

Both documents define guideline RF power density limits for "Controlled" and "Uncontrolled" environments. An uncontrolled environment is defined as one in which the person subjected to the RF radiation may be unaware of and has no control over the radiation energy received. The uncontrolled environment conditions can arise, even in the best-regulated operations and for this reason, the limits defined for the uncontrolled environment have been assumed for the Vislink recommended limit.

Documents a) and b) also show the RF power density guidelines to be frequency dependent. Different power density / frequency characteristics are presented in the two documents. To avoid complexity and to avoid areas of uncertainty, Vislink recommends the use of a single power density limit across the frequency range 100 kHz to 300 GHz. The 1w/m² power density limit we recommend satisfies the most stringent of the guidelines published to date.

NOTE: The IICNIRP document is freely available for download from the internet at

www.icnirp.de/emfgdl (PDF file) the IEEE standard is available on loan from Essex County Library on payment of a search fee.

2. Introduction

The Diversity System is an extension to the highly successful MVL-HD series of microwave links. The first truly digital microwave link to meet the requirements of digital television outside broadcasts. The Diversity system is primarily used in conjunction with a mobile Vislink transmitter; for example the D-Cam Clip-On unit wireless camera, “on-board” transmitters, or as a central receiving station to provide 360-degree coverage for citywide reception and helicopter downlinks.

This version of the receiver features both H264/MPEG-4 and MPEG-2 decoding with automatic selection.

The Diversity Control Unit takes the form of a 2U 19” rack mounted unit. The associated RF

Head unit(s) are machined out of solid aluminum to provide exceptional mechanical strength. They are of modular design for easy access and flexibility; the Diversity Control Unit and Head units are connected together via Triax cable; the cable may be up to 600m in length.

The output from the Receiver features a comprehensive range of signal formats for video and audio, including HD and SD SDI video, PAL/NTSC analogue video, AES/EBU digital, Dolby E and Dolby D pass-through, SDI embedded and analogue audio, together with IP encapsulated ASI data and HDMI. In HD mode, a down-converted CVBS monitor output is also provided.

The received video may be monitored on the front panel LCD color screen where security clearance allows.

The menu control and monitoring uses six push buttons for ease of operation, and allows the complete Receiver set-up to be controlled from the front panel. Remote monitoring via Ethernet is also provided.

The Receiver will accept a wide range of AC and DC power options. Powering will automatically switch to DC, with no break, in the event of a failure of the AC supply.

7. Preparing for Operation

Equipment Operation

Before leaving the equipment base to undertake an operation it is recommended that the following equipment checks be made.

MVL HD3 Diversity Receiver

7.2.1. Antennas

The MVL-HD3 Diversity Receiver can be used with a variety of Gigawave antennas

 FBA fan-beam antennas are used for wireless camera and on-board reception, or

when 4 are used in combination for 360 degrees ENG central city receive sites or helicopter downlink reception. Fan beam antennas offer increased gain and 90-degree sector coverage.

 HX series Helix antennas are circularly polarized antennas with increased directivity

and gain.

 CO series Colinear antennas are used for Omni reception.  PA series Low profile antennas are used for up-linking ground to air, or on-board

linking.

 Parabolic antennas offer the highest gain, and longest operation range.

Full details are given in the Gigawave Antennas data sheet.

7.2.2. Checks

We recommend completing the following minimum checks in the workshop, before you leave for the filming site.

 The receiver may be powered from 100/240VAC or DC PSU or by batteries.

 Check that any batteries to be used are fully charged and that an emergency spare

battery is available and fully charged.

 Confirm the correct frequency is selected (see Section 6.7.1).  Confirm that the correct digital outputs are selected, SDI or ASI (see Section 6.7.3.2).  Confirm the correct Analogue Audio level is selected (see Section 6.7.3.1.1).  Check that the Video, audio, DC and RF cables are in good condition.  Ensure that suitable keys are programmed into the unit.

NOTE: If the OSD is displaying a key number then decryption is not possible as the keys

stored in the unit do not allow access, or are missing.

Transmitter/Receiver Tests

Whenever practical, set up the system and trial it before leaving for site to ensure that all components of the system are working. Checking at base, where adjustments and corrective actions can be made, will pay off when setting up at site.
