In addition to Fast Speed display, the S targets and same lane targets.

Utilizing a state-of-the-art Digital Signal Processor (DSP), S accuracy previously unavailable. The DSP performs the critical filtering and timing functions required for speed measurement in its software, as opposed to its hardware. This provides less unit-to-unit variation, more reliable performance, and easier maintenance. One of the unique features of the S new software, preventing obsolescence!

S DUAL DSR operates in Ka-band from 33.4 to 36.0 GHz and prov ides a hold mode. Both Ka-band operation and the hold feature reduce the possibility of detection by radar detectors. Target-speed locking with Voice Enunciators, Track-thru-Lock speed, Fast Speed Tracking (both opposite lane and/or same lane), Direction Sensing, and the Doppler audio capability assist the operator in positive target identification and provide operating convenience.

DUAL DSR offers Fast Speed locking in moving mode for both opposite lane

INSTALLATION

S DUAL DSR consists of a dash-mounted display unit; a counting unit that can be mounted with the display unit, or separately using the optional Remote Cabling Kit (P.N. 200-0247-00); one or two antenna units; and a wireless or wired remote control unit. S Each system component should be installed in a location that provides good operator visibility and convenience, but does not obscure the road or interfere with air bag operation. The Ka-band antenna units are fully waterproof and may be installed outside the vehicle, if desired. The display and counting units are not waterproof and must be installed in a location sheltered from the weather. Longer cables are available from the factory for specific installatio ns, if needed.

Display/Counting Unit - To mount the combined display/counting units, connect the Power Cable to the power jack on th e

back of the counting unit. Plug the front and/or r e ar antenna cables into the back of the counting unit. If using only one antenna, plug it into the front combined display/counting unit into the mount and secure with thumbscrews (provided) into the threaded holes located on each side of the counting

Display Unit - To mount the display unit only, separate the counting unit from the display unit by unscrewing the two screws on

the back panel. Connect the 15-pin cable, supplied in the Remote Cabling Kit, to the connector on the back of the display unit. Attach the display unit to the mounting bracket using one thumbscrew on each side or attach directly to the dash. After mounting, make sure the display will not dislodge during high-speed maneuvers.

Counting Unit - To mount the counting unit separately from the display unit, select an out-of-the-way mounting location, such

as under the dash or under the front seat. Connect the Power Cable to the power jack located on the back of the counting unit. Plug the front and/or rear antenna cables into the back of the counting unit. If using only one antenna, plug it into the front Connect the 15-pin cable, supplied in the Remote Cabling Kit, to the connector on the front of the counting unit. Secure the mounting bracket on the counting unit to a suitable mounti ng surface with Velcro or screws. Install the counting unit into the bracket using a star knob on each side.

Antenna Unit - Before proceeding with the final installation, check the intended mounting locations for fan interference on

both antennas. See the section on fan interference, page 20. Find a suitable location and attach the antenna mounting bracket to

the selected mounting surface. Attach the antenna unit to the bracket. Connect the antenna cable to the antenna. Repeat these steps for the second antenna, if desired.

Cordless Ergonomic Remote Control - The only installation required for the ergonomic remote control is to install the 3V

123 battery. Remove the battery compartment cover by pressing down on the battery cover latch and rotating the battery cover away from the case. Install the battery, paying attention to the polarity markings. Replace the battery cover until it snaps in place. Velcro may be applied to the back of the remote control unit to attach it to the dash or other locations. Also, a microphone lug (supplied) can be attached to the back of the ergonomic remote control to allow installation into a microphone holder. An optional lanyard is also available.

Wired Remote Control - The Wired Remote Control requires that the Standard Power Cable (P.N. 155-2058-00) be replaced

with the Power Cable with Serial Port (P.N. 155-2058-01). This provides the connector needed to plug in the Wired Remote.

DUAL DSR is powered from the 12-volt, vehicle power system using a Power Cable from the counting unit.

jack.

THEORY OF OPERATION

Stationary Mode - All traffic radar uses the Doppler frequency shift technique to measure the speed of moving vehicles. This

technique is based on the Doppler Theory, which states that a radar signal reflected from a moving target will experience a frequency shift that is proportional to the speed of the target relative to the radar. Circuitry in the traffic radar then processes the reflected signal to obtain the frequency shift and translate this frequency shift to speed.

In stationary mode, the transmitted signal strikes a moving target and is reflected back to the antenna. The traffic radar then measures the frequency shift to obtain the target speed.

Prior to the introduction of the S

DUAL DSR, traffic radar could not sense the direction of vehicles in the radar beam. In

conventional traffic radar, targets both closing and moving away generate the same Doppler frequency shift, and it is not possible to distinguish between them. Therefore, a stationary radar always reads the speed of all vehicles in its beam (both closing and moving away) and the operator had to rely on visual observation to determine target direction.

DUAL DSR is the first practical radar to use a dual channel antenna design. Each antenna actually has two sets of

microwave circuits and two sets of amplification/digitizing circuits. The two microwave circuits are designed to provide two simultaneous Doppler signals with a 90° phase difference depending on direct i o n.

Both channels of digitized Doppler information are sent to the DSP (Digital Signal Processor) circuit in the counting unit. A highspeed DSP circuit then performs a Complex Fast Fourier Transform

computation simultaneously on each channel to obtain relative

direction for each target.

Opposite Lane Moving Mode - In opposite lane moving mode, two (2) signals must be processed to determine target speed.

The first signal, patrol speed, results from the radar signal reflecting from passing stationary objects. Since the Doppler shift is proportional to the relative velocity between the radar and the passing reflecting objects, the Doppler shift of this signal will be proportional to the speed of the patrol vehicle. The second signal, closing speed, results from the radar signal reflecting from an approaching or retreating opposite lane moving target back to the patrol vehicle. The Doppler shift of this signal will be proportional to the sum of the patrol speed and target speed, or closing speed. To determine the target speed, S

DUAL DSR

subtracts the patrol speed from the closing speed.

Same Lane Moving Mode - In same lane moving mode, two (2) signals must be processed to determine target speed. The

first signal, patrol speed, results from the radar signal reflecting from passing stationary objects. Since the Doppler shift is proportional to the relative velocity between the radar and the passing reflecting objects, the Doppler shift of this signal will be proportional to the speed of the patrol vehicle.

The second signal, difference speed, results from the radar signal reflecting from an approaching or retreating same lane moving target back to the patrol vehicle. The Doppler shift of this signal will be proportional to the difference speed between the patrol and target vehicles. If the target vehicle is moving faster than the patrol vehicle, the difference speed will be added to patrol speed to obtain target speed. If the target vehicle is moving slower than the patrol vehicle, the difference speed will be subtracted from the patrol speed to obtain target speed.

Prior to the introduction of the S “tell the radar” whether to add or subtract lane radar requires the operator to obtain the “correct speed” by the “correct position” of the “Slower” key on the remote control.

The unique Direction Sensing ability of the S DUAL DSR allows the radar to automatically (without the traditional “slower key”) determine the correct speed of all

same lane targets in the radar beam.

Fast Mode - S DUAL DSR offers a feature called Fast Speed Tracking. Fast Mode is a field selectable feature and can be

disabled, if desired. Three options are available: 1) Fast Mode disabled, 2) Fast Mode enabled for opposite lane targets only, and

3) Fast Mode enabled for both opposite lane targets and same lane targets (factory default setting). The addition of the fast mode allows the ability to track small high speed targets that normally could not be tracked because a

stronger target shields the weaker target from normal speed measurement. The classic example is where a speeding sports car passes a slower moving eighteen wheeler. The faster sports car, although clearly speeding, previously could not be measured because the strongest truck target captures the target display window. S of the strongest truck in the target window, while the speed of the faster sports car will appear in the middle fast window. Tracking of both targets may be performed simultaneously.

DUAL DSR, a radar operator had to observe the relative speed of the target vehicle and

the difference speed from the patrol speed as described above. A conventional same

DUAL DSR, in this example, will display the speed

DISPLAY OPERATION

Display Front Panel

Display Unit Functions

PWR: The PWR switch is the main On/Off power switch. S DUAL DSR has a jumper in its

power-supply circuit that selects one of the two following options:

1. When vehicle power is applied, the unit must be turned on by pressing the PWR switch. This is the normal factory setting.

2. When vehicle power is applied, the unit always powers on automatically, but may be turned off by pressing the PWR switch. If this setting is desired, call the factory.

TARGET WINDOW: The left, three-digit LED window is the target window. This window displays the speed of the

strongest target entering the radar beam. While in stationary mode, the target window will show the speed of the strongest target (SA) or the strongest moving mode, the target window will show the speed of the strongest approaching target or the strongest the target window will show the speed of the strongest

MIDDLE WINDOW: The middle, three-digit LED window is a dual purpose

the strongest target shown in the left window. While not containing a “locked” speed, the middle window is used to display the faster target in the radar beam. The LOCK and FAST icons are used to indicate the current status of the window.

The middle window is used to store target speeds that the operator chooses to "lock" using the

LOCK key. The presence of the LOCK icon indicates that the middle window contains a "locked" target speed. Every speed lock will be followed immediately by a 3-word voice enunciator that indicates antenna/radar mode/direction. Examples: FRONT/STATIONARY/CLOSING, FRONT/STATIONARY/AWAY,

REAR/STATIONARY/CLOSING, REAR/STATIONARY/AWAY, FRONT/OPPOSITE/CLOSING, REAR/OPPOSITE/AWAY, FRONT/SAME/CLOSING, FRONT/SAME/AWAY, REAR/SAME/CLOSING, OR REAR/SAME/AWAY.

Targets in either the same lane or opposite lane can be displayed and locked in the middle

window.

When no LOCK target is present, the middle window is used to track the faster target in the

radar beam. This is indicated by the presence of the FAST icon.

PATROL WINDOW: The right, three-digit LED window is the patrol window. In moving mode, the operator should

always verify that the patrol window is tracking the patrol vehicle’s speedometer. After locking a target speed, the patrol window may be "blanked" by pressing the PS BLANK key. Restore the patrol speed by pressing the PS BLANK key a second time.

XMIT: The XMIT icon indicates that S FRONT: The FRONT icon indicates the front antenna is selected for use. The icon will light with a

steady indication if the antenna is operational, or a blinking indication if the antenna is missing or inoperative.

REAR: The REAR icon indicates the rear antenna is selected for use. The icon will light with a steady

indication if the antenna is operational, or a blinking indication if the antenna is missing or inoperative.

FORK: The FORK icon indicates the radar is in tuning fork mode. Immediately following the Internal

Circuit Test (activated with the SELF TEST key), the FORK Icon lights for 60 seconds.

SAME: The SAME icon indicates that the radar is in same lane mode. Conversely, opposite lane

mode is indicated by the absence of the SAME icon.

LOCK: An illuminated LOCK icon indicates that the operator has locked a target speed in the middle

window. Every speed lock will be followed immediately by a 3-word voice enunciator that indicates antenna/radar mode/direction. Illuminated LOCK and FAST icons indicate a locked faster speed target.

RFI: The RFI icon indicates the presence of an interfering signal. Operation is inhibited during an

RFI indication.

Lo V: The Lo V icon illuminates when the input voltage falls below 9.0 volts. Operation is inhibited

while this icon is displayed, but normal operation will resume automatically when the input voltage is restored to a normal voltage.

FAST: An illuminated FAST icon, above the middle window, indicates that the middle window will

display a faster speed target if one is found. Illuminated LOCK and FAST icons indicate a locked faster speed target.

ERGONOMIC REMOTE CONTROL FUNCTIONS

The Remote Control can be operated in wired mode by connecting a standard RJ-11 modular telephone handset cord (P.N. 155-2213-00 or Radio Shack #279-312). The cord is connected to the remote and radar unit, and battery removed for wired operation.

Fig 1

The ergonomic remote control shown above is the standard control supplied with the S

DUAL DSR radar unit. An optional

remote, shown on Page 10, with a different case and key configuration, is also available.

STRONG LOCK/REL or STOPWATCH MODE: This dual-function key controls both the Radar Mode function STRONG LOCK/REL and

STOPWATCH MODE initiation.

STRONG LOCK/REL: In Radar Mode, the STRONG LOCK/REL key alternates between target lock and release

functions. The first time the STRONG LOCK/REL key is pressed, with a speed in the target window, that strong target speed is transferred to the middle window and locked along with the present patrol speed. This state is indicated by the illumination of the LOCK icon. Pressing STRONG LOCK/REL a second time clears the locked contents of both the lock and the patrol windows.

Every speed lock will be followed immediately by a 3-word voice enunciator that indicates

antenna/radar mode/direction . Examples: FRONT/STATIONARY/CLOSING, REAR/OPPOSITE/AWAY, or FRONT/SAME/CLOSING.

During lock, the LOCK icon will light. The target window and Doppler audio remain active

after locking.

The other function of the STRONG LOCK/REL key is turning on and off the faster target

lock feature. When the operator presses the STRONG LOCK/REL key with an empty target window, the unit will acknowledge with a beep and switch between faster target tracking ON and OFF. The presence/absence of the FAST icon on the display represents the enabling/disabling of the faster target window.

STOPWATCH MODE: Hold down the STOPWATCH MODE key for 2 seconds to toggle the radar between Radar

Mode and Stopwatch Mode. The display changes when the key is pressed, indicating the mode of operation.

MOV/STA: The MOV/STA key is used to alternate between moving and stationary modes. It toggles

between the four operating radar modes. They are: 1) moving ([ ]), 2) stationary closing (SC),

3) stationary away (SA), and 4) bi-directional stationary (S_) modes. A speed or a [ ] in the

patrol window indicates moving.

Different audio tones are used to indicate different Radar

Modes. While operating in VSS mode (see section titled “VSS OPTION” on Page 25) the radar uses the presence (or absence) of VSS pulses to automatically switch between moving mode and stationary mode.

SAME/OPP: The SAME/OPP key is used to alternate between same lane and opposite lane modes. The

SAME icon toggles on and off to indicate same lane mode.

ANT: The ANT key is used to switch between the front and rear antennas, unles s the radar was

factory set for only one antenna. The FRONT or REAR icon will light. The display unit can sense the presence or absence of the front or rear antenna. A steady icon indicates an operational antenna and cable, while a blinking icon indicates a missing antenna and/or cable, or a malfunction of the antenna unit.

XMIT/HLD or S/S: XMIT/HLD: The XMIT/HLD key toggles between XMIT (transmit) and HLD (standby). The XMIT icon

will light for transmitting and extinguish for hold.

S/S: When in Stopwatch Mode, the S/S key is used to start and stop the electronic timing of the

target vehicle as it enters and exits the speed measurement zone.

FAST LOCK/REL: In Radar Mode, the FAST LOCK/REL key alternates between faster target lock and release

functions. The first time the FAST LOCK/REL key is pressed, with a fast target in the middle window, that fast speed is locked along with the present patrol speed. This state is indicated by the simultaneous illumination of both the FAST icon and the LOCK icon. Pressing FAST LOCK/REL a second time clears the locked contents of the middle and the patrol windows.

Every speed lock will be followed immediately by a 3-word voice enunciator that indicates

antenna/radar mode/direction . Examples: FRONT/STATIONARY/CLOSING, REAR/OPPOSITE/AWAY, or FRONT/SAME/CLOSING.

During lock, the LOCK icon will light. The target window and Doppler audio remain active

after locking.

SEn or 100: This key has two functions. SEn: The SEn key is used to adjust the range up or down at any time. Maximum range (sensitivity)

is SEn 4, minimum range (sensitivity) is SEn 1. The range (or sensitivity) must be set separately for same lane moving mode and opposite lane moving mode. While in each

mode,

(same lane and opposite lane), indicated by the presence or absence of the SAME icon, set each sensitivity as described above.

100: While in STOPWATCH MODE, the 100 key is used to set the 100s digit (in yards) of the

length of the speed measurement zone.

SQL or 10: This key has two functions. SQL: The SQL key toggles the squelch override on and off. In the normal position, audio will be

heard only when a target is being tracked.

In addition the SQL key is used in conjunction with the

key to adjust the volume of the

voice enunciators – see below.

10: While in STOPWATCH MODE, the 10 key is used to set the 10s digit (in yards) of the

length of the speed measurement zone.

PS 5/20 or 1: This key has two functions. PS 5/20: The PS 5/20 key is used to select one of the two selections for low end patrol speed of either 5

or 20 mph. For example: a patrol window indication of 20 starts tracking patrol speed at 20 mph, while a patrol window indication of 5 starts tracking patrol speed at 5 mph. If the VSS feature is enabled (see section titled “VSS OPTION” on Page 25), the PS 5/20 key will only display SP when pressed.

1: While in STOPWATCH MODE, the 1 key is used to set the 1s digit (in yards) of the length

of the speed measurement zone.

SELF TEST: The SELF TEST key performs a diagnostic check on the display/counting unit and antenna.

The display/counting unit will complete a display segment test, processor check, memory

check, and crystal check, followed by the display of speeds of 10, 35, and 65. A comprehensive test is also performed on the selected antenna by the counting unit to ensure the integrity of the antenna cable and antenna electronics. PASS or FAIL is indicated on the display unit after all tests have been completed.

Immediately following the Internal Circuit Test (activated with the SELF TEST key), the

FORK Icon lights for 60 seconds. During this 60-second interval, direction sense operation is disabled allowing conventional tuning fork calibration. See page 23.

(Target Doppler) The key is used to adjust the volume of the Target Doppler audio up or down. Press the

key to make the display step through: Aud 1, Aud 2, Aud 3, and Aud 4. Aud 1 is lowest and Aud 4 is the loudest.

(Voice Enunciators) The key is used in conjunction with SQL key to adjust the volume of the voice enunciators.

Press the

key followed by the SQL key to make the display step through:

u 0, u 1, u 2, and u 3. u 0 is off and u 3 is loudest.
