1.5. General Description of system
The ACU has been designed and manufactured so as to be inherently reliable, easy to maintain, and simple
to operate. Except for start-ups, or when changing to operate with different transponders or satellites, the
equipment essentially permits unattended operation.
This Antenna Control Unit will be connected to an Antenna and other equipment to form a system. The
system consists of two major groups of equipment; an above-decks group and a below-decks group. Each
group is comprised of, but not limited to, the items listed below. All equipment comprising the Above Decks
is incorporated inside the radome assembly and is integrated into a single operational entity. For inputs, this
system requires only an unobstructed line-of-sight view to the satellite, Gyro Compass input and AC
electrical power.
The following text provides a basic functional overview of the system components and component
interconnection as referred to in the System Block Diagram(s) for your model antenna.
Television Receive Only (TVRO) Systems are comprised of two major sections: The Above-Decks
Equipment (ADE) is comprised of the Sea Tel antenna & radome assembly which is mounted outside, on an
upper deck location chosen for best satellite reception. The Below-Decks Equipment (BDE) includes the
Antenna Control Unit and will have satellite receiver(s), TV set(s) and all other ancillary equipment that is
mounted in various locations throughout the interior of the ship.
Transmit/Receive (TXRX) Systems are also comprised of two major sections: The Above-Decks
Equipment (ADE) is comprised of the Sea Tel antenna & radome assembly which is mounted outside, on an
upper deck location chosen for best satellite reception. The Antenna inside the radome has Transmit &
Receive RF equipment mounted on it. The Below-Decks Equipment (BDE) includes the Antenna Control
Unit and will have satellite modem, Multiplexer and all other ancillary communications equipment that is
mounted in various locations throughout the interior of the ship.
For more information refer to the Basic System Information section of this manual, to your Antenna manual
and to the other manuals for equipment which was included in your system.
