INTRODUCTION
INTRODUCTION
This Directional Radar Unit, known as DRU III, is
designed and built for target speed sensing applications.
The DRU III has designed for flexibility, simple
operation, small size and extremely low current
consumption. The DRU III is intended for uses in traffic,
industrial, and sports products. Examples of these
applications are the Kustom Signals’ S.M.A.R.T. series
trailers, Pole Mounted Speed Displays and StealthStat
statistics gathering systems.
The DRU III is designed to be an extremely flexible unit.
Kustom Signals provides PC software to allow the user to
setup the DRU III to operate in many different
configurations.
The radar itself is incredibly simple to operate--just
connect it to a compatible display or PC, and power it up.
The DRU III will output RS232 speed data in the selected
output protocol as long as the unit is powered.
With a size of only 3” x 3” x 1.5” the DRU III is a
complete one-piece unit, that can easily be mount to the
user’s equipment.
The DRU III sets a new standard for low current
consumption. This dramatically improves run times in
battery-operated applications.
The DRU III has Kustom Signals' uncompromising
quality inside to give you years of trouble-free, accurate,
reliable, speed measurements.
