Page 7: Introduction
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. -

SYSTEM OPERATION RADAR REAR VIEW A. RUBBER WASHER: (2ea.) Rests on mounting screws between mounting bracket and radar unit. B. MOUNTING BRACKET SCREW: (2ea.) Connects bracket to radar unit. C. INDICATOR LED: Strongest target direction indicator. D. OPTIONAL MOUNTING INSERTS: (4ea.) Provides optional mounting for customer’s brackets. -
Page 9: Configuration Options
SYSTEM OPERATION CONFIGURATION OPTIONS The DRU III 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 III can output speeds for targets traveling in the direction of: a. - Page 10 6. Output Protocol: The DRU III can output one of several different protocols. Including outputs in HEX, ASCII, multiple targets, tenth units, and many others. 7. Output Baud Rate: The DRU III can be set to output RS232 data at rates of (19200, 9600, 4800, 2400, or 1200) baud.
- Page 11 If the DRU III is set to the Polled output, data is output when the DRU III receives characters [“*P”] or [“*P”0x0D].

Page 12: Installation
1. Mount the radar in its bracket. 2. Attach the end of the power/data cable to the 6-pin connector on the back of the DRU III. Ensure the plug and socket is aligned properly before tightening the screw ring. Ensure the connection is firm and tighten the connector’s screw ring. -
Page 13: Tuning Fork Test
SYSTEM OPERATION TUNING FORK TEST The DRU III unit can be configured to output speeds of targets that are approaching only, receding only, both approaching and receding, or all targets including non- directional targets. Tuning forks can only be reliably read in the all targets mode. - Page 14 SYSTEM OPERATION 3. Extremely cold or extremely hot tuning forks may give readings slightly above or below those specified, due to the effect of extreme temperature on the metal. If this is the case, warm or cool the forks to normal room temperature before use.

Page 15: General Information
Flash RS232 Serial Port EE Memory The Directional Radar Unit (DRU III) transmits a radio frequency of 24.125 Gigahertz, in accordance with Federal Communications Commission regulations. When the transmitted signal strikes a moving target, it returns at a different frequency because there is relative motion between the two objects (radar unit and target). - Page 16 GENERAL INFORMATION This returning signal is mixed with the transmitted signal in a balanced I/Q demodulator mixer. The difference in frequency (Doppler frequency) is proportional to the speed of the target; the difference in phase is related to the direction of target travel. These returned echo signals are a very low level.

5. Gray -- Ground 6. Pink – Open collector alarm LED INDICATOR The DRU III has a bicolor LED to indicate the status of the current strongest valid target. The statuses the LED can indicate are as follows: 1. Short burst of flashing red = DRU III is running, no valid target present. -
Page 18: Interference
Power transformers, radio transmitters, fans, etc generate electronic noise signals. If the power supply voltage to the DRU III unit drops below the level required for proper operation, power to the microwave transmitter will be turned off. This prevents false readings from occurring during periods of low voltage. -
Page 19: Recommended Care & Maintenance
NEVER wire directly into AC current!! 3. Do not pick up or carry the DRU III by the power / data cable. Do not yank or twist the cable, especially near the base. Broken wires inside the cables are a common cause of intermittent operation. -
Page 20: Ksi Radar Microwave Emission
Standards Institute, which recommends a maximum power density of 10.0 mW/cm for the frequency bands on which Kustom Signals traffic radar systems operate (ANSI C95.1- 1994, "American National Standards Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 300 KHz to 100 GHz"). - Page 21 While traffic radar devices do emit microwave radiation, the levels are so low that there are no possible harmful effects. You may use your Kustom Signals radar unit with complete confidence in its safety, as well as in its accuracy.
