System Overview
Your Datron DBS-4500 is the first fully automatic in-motion satellite system specifically designed for
use with the new high-power DBS television satellites. The satellites have revolutionized television in
the United States and have made DBS television receiving systems the fastest selling consumer
electronics product in history.
The DBS-4500 has been designed for simplicity of operation. The DBS-4500 incorporates the latest
solid state satellite tracking technology with advanced computer software to give you, our customer,
true value and years of entertainment enjoyment.
Datron has been designing and manufacturing satellite tracking systems for military and commercial
customers worldwide since 1969
.
This experience has created this revolutionary new satellite
television receiving system.
The DBS-4500 has three main parts, the Antenna/Radome Assembly, the ACU, and the Satellite
Receiver. Since your DBS-4500 was probably installed by a Datron dealer, we will give you some
background on the system.
2.1
Antenna/Radome Assembly
The DBS-4500 uses a specially designed 12” x 24” parabolic reflector (dish) and an LNBF to receive
the DBS satellite’s signals. The antenna and its drive motors are covered by a low-profile protective
cover called a radome. The dish is automatically and continuously pointed at the satellite by the
antenna control unit (ACU) while the vehicle rolls down the road. The radome is specially designed
and molded from a material that is strong and light weight and must
not
be painted with metallic based
paints. The metallic content of many paints will severely impair system performance.
2.2
Antenna Control Unit (ACU)
The ACU is located under the radome. The ACU contains the motion sensing devices that give the
ACU’s computer the information it needs to keep the antenna accurately pointed at the satellite as the
vehicle turns, sways and rolls over bumps. Your only interface with the ACU is “ON” or “OFF”
through the remote switch in your vehicle.
2.3
Satellite Receiver
The final main part of the system, other than your TV, is the satellite receiver. The receiver is the
same type of unit you would use to view DBS television in your home. Appendix A contains a matrix
of compatible receivers.
