INTRODUCTION
The S DSR 2X is a Ka-band Direction Sensing Radar designed to allow the speed enforcement officer maximum flexibility
both in moving and stationary modes. The unique Direction Sensing ability of the S
DSR 2X allows the radar to automatically
(without the traditional “slower key”) determine the correct speed of all
same lane targets. In addition, the S DSR 2X can
simultaneously monitor two of the four Target Zones in moving mode.
In addition to Fast Speed display, the S
DSR 2X offers Fast Speed locking in moving mode for both opposite lane targets and
same lane targets.
The S
DSR 2X offers, for the first time, a new feature called Rear Traffic Alert. The Rear Traffic Alert feature is designed to
warn an accelerating patrol vehicle of approaching rear same lane traffic. See the Rear Traffic Alert section of this manual on page 7.
Utilizing a state-of-the-art Digital Signal Processor (DSP), S
DSR 2X provides a level of performance, convenience, and
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
DSR 2X is that it can be upgraded in the future by simply installing new software,
preventing obsolescence!
S DSR 2X operates in Ka-band from 33.4 to 36.0 GHz and provides 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), Target Direction Arrows, and Target Doppler Audio capability assist the
operator in positive target identification and provide operating convenience.
INSTALLATION IS THE KEY TO PERFORMANCE
S DSR 2X 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
DSR 2X is powered from the 12-volt, vehicle power system using a Power Cable from the counting unit. 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 can 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 installations, if needed.
Display/Counting Unit - To mount the combined display/counting units, connect the Power Cable to the 9-pin connector on the
back of the counting unit. Plug the front and rear antenna cables into their respective connectors on the back of the counting unit.
After attaching the mounting bracket to the selected mounting surface with Velcro or screws, insert the combined display/counting
unit into the mount and secure with thumbscrews (provided) into the threaded holes located on each side of the counting
unit.
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 rear antenna cables into the back of the counting unit. 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 mounting 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 3. 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.
Ergonomic Remote Control - The only installation required for the ergonomic remote control (P.N. 200-0579-00 Fast-Lock
model; 200-0579-01 Instant-On model) 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 Cable - 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.
