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.
