!
CAUTION The unit will exit recall mode after the recall button is NOT
pressed for 2 seconds.
The unit will exit recall mode if the unit begins transmitting.
6. Clocking A Speed Reading
The JUGS Gun™ detects targets moving either toward or away from it. The
radar measures the true release speed with an accuracy of +1 display unit,
approximately 12 inches (30 centimeters), from the pitcher’s hand before
the pitch loses speed. For the most accurate reading, stand to one side
of the catcher and point the gun toward the pitch so the radar beam is
parallel to the direction of the ball. Also, you can stand behind the pitcher
to position the radar. The radar will detect speeds within a 300 feet (91
meters) range. However, when the gun is closer to the release pitch, the
speed reading is more accurate.
The radar gun operates in five modes: Fast, Last, Fast/Last,
Continuous and Auto.

7. Serial Output
The JUGS Gun™ has an RS232 communications port on the bottom of the
handle. Using a custom RS232 communications cable, you can connect
the radar and transmit data to display signs or to a PC for recording and
analyzing speed data. Figure 7 illustrates the location. The port format is:
ASCII, 1200 Baud, One (1) Start bit, Eight (8) Data bits, One (1) Stop bit, No
parity .

Port location as shown on The JUGS Gun™
8. Performance Tips
Understanding potential radar interference and what to do when it occurs
can greatly increase the radar’s performance.
8.1 How Radar Works
Determining a target’s speed begins with the radar gun transmitting a
beam of microwave energy (radio waves) at an approaching or departing
object. When energy from this beam strikes an object, such as a baseball, a
small amount of the beam is reected back to the antenna. The reflected
signal frequency shifts by an amount proportional to the speed of the
object. This is known as the Doppler eect. The radar device then
determines the object’s speed from the dierence in frequency between
the reected and transmitted signal.
19
8.2 Interference Sources
When properly installed and operated, Doppler radar technology is
extremely accurate and reliable. However, variations in the environment
can cause situations and circumstances which can cause spurious (erratic
and unusually low or high) speeds to display. Signs that a speed is spurious
can include the following characteristics:
• A reading appears when no target is in the operational range of the
antenna.
• A target entering the operational range overrides the interference
signal, causing the displayed speed to change suddenly.
• Speeds are irregular and do not provide a valid reading.
8.2.1 Angular Interference (Cosine Error Effect)
The cosine error eect causes the radar device to display a speed, which is
lower than the actual pitch-release speed. This condition exists whenever
the target’s path is not parallel to the gun’s antenna. As the angle between
the beam of the antenna and the target increases, the displayed speed
decreases. An angle of zero (0) is best.
Figure 8.2.1a
An angular error occurs when the target’s path is not parallel to the radar antenna
The following table shows the eect that an increasing angle has on a
displayed speed.
Small angles (less than 10°) have little eect on accuracy. As the angle
increases, the displayed speed decreases. At 90°, the target speed is 0—
grossly incorrect .
8.2.2 Electromagnetic Interference (EMI)
Operating electric motors can produce EMI. To correct the interference,
simply turn o its source.
8.2.3 Feedback Interference
When the radar beam is directed at laptop computer screens, streetlights,
and other electronic devices, it can display spurious speeds. To correct the
interference, relocate the radar gun’s antenna.
8.2.4 Radio Frequency Interference
The system can inadvertently process radio energy as Doppler speeds,
including that from police radios, airport radar, microwave transmission
towers, CB radio transmitters, and AM/FM transmission towers. For this
type of interference to occur, the radar gun must be operating very close
to the radio transmitter.
8.2.5 Scanning
™
The JUGS Gun
is designed to be used while attached to a solid mount or
hand-held in a steady position. Moving or “scanning” the antenna past stationary objects can cause the system to detect motion. Obtaining a speed
reading from scanning will not happen when you properly use the radar
and is considered deliberate misuse of the system.
8.2.6 Environmental Conditions
Fog, rain, snow, and blowing dust can reduce the detection range.
9. Care, Cleaning, and Storage
• Avoid spilling food, beverages and other liquids on the radar device.
• When you are not using or transporting the device, store it in its
original packaging.
• To clean the radar device, dust it with a soft clean cloth, which is free
of cleaning solutions .
