Installation

Introduction

This section deals with installing and connecting your Rayma- rine HD-ACU which is compatible with both 45 and 60STV systems.

HD programming

In order to receive High Definition programming from the DirecTV 110 West satellite, your satellite TV system requires an HD-ACU. The HD-ACU comes as standard when you purchase the following system packs:

•E93013 - 45STV HD System pack.

•E93014 - 60STV HD System pack.

If you already own a Raymarine Satellite TV system, you can upgrade your system by doing the following

•Purchase an HD-ACU - Raymarine Part No. R08255.

•Remove the standard ACU from your system and replace it with the HD-ACU.

•Run cables according to the diagram on Pages 9 or 11 depending on your needs. The RF1 cable will have to be connected to the HD-ACU in either case.

•Set the satellite pairs to those listed below:

Your HD-ACU has the following pre-set satellites pro- grammed into the software:

•Sat A - DTV 101 and Sat A* - DTV 119

•Sat B - DTV 101 and Sat B* - DTV 110#

For full details of how to set up your HD-ACU refer to your Satel- lite TV System Handbook - Document No. 81258_3.

EMC installation guidelines

All Raymarine equipment and accessories are designed to the best industry standards for use in the recreational marine environment.

Their design and manufacture conforms to the appropriate Elec- tromagnetic Compatibility (EMC) standards, but correct installation is required to ensure that performance is not compro- mised. Although every effort has been taken to ensure that they will perform under all conditions, it is important to understand what factors could affect the operation of the product.

The guidelines given here describe the conditions for optimum EMC performance, but it is recognized that it may not be possible to meet all of these conditions in all situations. To ensure the best possible conditions for EMC performance within the constraints imposed by any location, always ensure the maximum separation possible between different items of elec- trical equipment.

For optimum EMC performance, it is recommended that wher- ever possible:

•Raymarine equipment and cables connected to it are:

•At least 3 ft. (1m) from any other equipment transmitting or carrying radio signals. In the case of Single Side Band (SSB) radio, the distance should be increased to 7 ft.

(2m).

•More than 7 ft. (2m) from the path of a radar beam. A radar beam can normally be assumed to spread 20 degrees above and below the radiating element.
