INTRODUCTION
INTRODUCTION
This Directional Radar Unit, known as DRU II, is
designed and built for target speed sensing applications.
The DRU II has been completely redesigned for
flexibility, simple operation, small size and extremely
low current consumption. The DRU II 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 II is designed to be an extremely flexible unit.
Kustom Signals provides PC software to allow the user to
setup the DRU II 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 II will output RS232 speed data in the selected
output protocol as long as the unit is powered.
With a size of only 3.5”x 3”x 2.25” the DRU II is a
complete one-piece unit, that can easily be mount to the
user’s equipment.
The DRU II sets a new standard for low current
consumption. This dramatically improves run times in
battery-operated applications.
Although the DRU has no frills outside, it has Kustom
Signals' uncompromising quality inside to give you years
of trouble-free, accurate, reliable, speed measurements.

SYSTEM OPERATION
CONFIGURATION OPTIONS
The DRU II was designed to give the user a configurable
radar unit that can be setup for their needs. A simple PC
program let the user select:
1. Target Direction: The DRU II can output speeds for
targets traveling in the direction of:
a. Approaching Only
b. Receding Only
c. Approaching and Receding
d. Non Directional (all targets output)
2. Sensitivity (Range): The DRU II can be set for
sensitivity from 5 (most sensitive) to 1 (least
sensitive).
