1 INTRODUCTION

This document provides instructions for installation, operation and maintenance of the Heli-Coder 4 (HC4) COFDM

Transmitter controlled by a DLC50 Downlink Control Panel.

BMS offers a wide selection of airborne products to meet the video and data requirements of today’s real world

applications. The Heli-Coder™ 4 (HC4) together with the DLC50 controller provides a simple, powerful solution

containing everything needed for high-quality, reliable transmission. This includes the video encoder, modulator,

up-converter and high-power amplifier and an intuitive powerful control interface (see Figure 1.).

Standard COFDM modulation offers excellent performance in urban and non-line of sight environments with

significant multipath. The HC4 also provides an integrated GPS data interface that reduces the components

needed to integrate location data into tracking systems. The HC4 provides everything required to achieve 10 W

output power in an ultra-compact case. The DLC50 control panel allows the HC4 unit to be mounted remotely

within the avionics bay while providing full control from the flight deck.

With the flexibility of MPEG-2 and H.264 compression, the HC4 efficiently handles SD or HD video and can be

configured to deliver high speed data as an ethernet radio. The HC4 is also Geo-Point™ capable. Geo-Point™

uses metadata supplied by the equipment serving as the video source and allows the display of bearing and

distance to the location shown on the screen in real time. (Geo-Point™ requires a compatible receiver.)

NOTE: The standard version of the HC 4 is configured to be controlled by a DLC50 Control Panel. Custom

configurations and control schemes may be supported. Contact BMS regarding your operational requirements and

the range of solutions BMS offers.

Broadcast Microwave Services (BMS) is a leader in wireless digital microwave technology providing innovative

products for the television broadcast, video, telemetry and surveillance industries. A wholly owned subsidiary of

Cohu, Inc., BMS designs and manufactures a comprehensive line of microwave communications equipment for

broadcasting sports venues, law enforcement and military applications. BMS also builds and integrates the

command and control centers to provide fully functioning, complex, end to end digital systems.

2 SAFETY

WARNING- RF Hazard: Non-Ionizing RF Emission

Operators of this equipment should be familiar with basic RF equipment operation and safety concepts. Users

must consider many unique factors to maintain RF safety. We offer the following guidelines with the

recommendation that each individual and organization establish an RF Safety and Awareness program based on

their combination of hardware and usage environment.

Radiation Exposure

The frequencies present in BMS equipment produce non-Ionizing radiation. The FCC reference document

regarding RF exposure limits is OET Bulletin 65 and can be viewed by visiting the FCC web site (www.fcc.gov ) or

by clicking here;

http://www.fcc.gov/Bureaus/Engineering_Technology/Documents/bulletins/oet65/oet65.pdf

(Link valid as of 6/25/2012)

We also reference EU Standard EN 50392 (02-2004). BMS references these standards as reasonable guidelines.

The OET 65 document sets maximum permitted exposure (MPE) and is widely cited within the U. S. and Canada.

Exposure is divided into two categories, “controlled” and “uncontrolled” environment. The uncontrolled

environment is the harshest criteria and applies to exposure where you may not be aware and/or cannot control

the exposure. Examples are where a residence is located near a cell site or other radio tower. You live there,

cannot remove yourself from the field and cannot control the RF. Exposure is long term and not in your control.

The “controlled environment” applies to most professional radio users. It is assumed they are trained in RF Safety,

they are aware there is an RF field, exposure is limited by transmission duty cycles, the flight or testing ends, hang

up the cell phone, put up the walkie-talkie, etc.

BMS recommends that operators use the uncontrolled exposure category from OET 65 as it applies to an

uncontrolled environment; a maximum power density limit of 1mW/cm².

The limit table from Bulletin 65 is reproduced below. X axis is frequency and y axis is mW/cm².

Heli-Coder 4 Transmitter Operation Manual | Doc. No. 6051452100 Rev. C

Broadcast Microwave Services, Inc. 3

Use the formula from OET65 to determine the minimum recommended distance according to your individual usage

circumstances.

Your organization should develop an understanding of its unique RF usage and create a plan to train personnel

regarding recommended exposure limits according to the FCC and EU recommendations.

General Safety Rules;

a) Do not operate the transmitter or power amplifier with covers removed.

b) Never walk in front of directional antennas when radiating.

c) Switch off supplies before removing covers or disconnecting any RF cables, and before inspecting damaged

cables or antennas.

d) BMS recommends returning the HC4 to the factory for service or repair.

In addition you can limit your exposure by raising awareness and using some common sense rules.

Default to low power if available using hi-power only as required.

Never stand in front of a transmitting directional antenna.

Limit transmission duty cycles (turn on/off as needed).
