GENESIS II

Decatur Electronics, Inc.
CPL Approved.

OPERATION

multi-piece dual antenna system
-- handheld remote
-- front and rear antennas (operator selects front, rear, or both)
-- Computer Processor (32 bit DSP - Digital Signal Processor)
output connector (RS-232) to interface with PCs, display signs, printer
X, K, and Ka models (antennas) available.
Instant On or continuous transmissions
stationary mode -- on-coming traffic (front and/or rear antennas)
moving mode -- on-coming traffic in opposite direction/lane (front antenna)
same-lane (optional) -- traffic traveling same direction/lane as patrol car (front and/or rear antennas)
NOTE: in same-lane mode patrol car speed must be 20 mph (32 kmh) or greater to acquire targets; target speed must be at least 2 mph (2 kmh) or more (slower or faster) than patrol car speed NOTE if both front and rear antennas active (stationary or same-direction/lane mode), target displayed may originate from either the front or rear antenna.
Track / display a faster target (optional)
-- In stationary or moving mode FAST button selects faster target for display
-- In same-lane mode FAST button toggles display between slower (stronger) AND faster targets In stationary or same-lane mode faster target may (or may not) orginate from a different antenna (direction) if both antennas active .
Audio Alert / Audio proportional to target speed
Manual-lock (Target Speed locked in separate display)
Manual Self-Test (also fault detection during use)
Auto Self-Test (optional)
Tuning Forks
Ka band -- (35.2 and 65.6 mph) or (55.2 and 105.6 kmh)
K band -- (32.2 and 50.6 mph) or (60.2 and 90.6 kmh)
communications port (to external devices, speed displays, etc.)
Beamwidth
12 degrees nominal (K and Ka band)
18 degrees (X band)
optional kmh display

CONTROLS (remote)

MODE -- moving / same direction / stationary (press for 2 sec)
LOCK (manual) target speed (hold button for 2 sec to clear)
FAST
-- selects faster target (stationary or moving modes)
-- toggles between slower or faster target (same-lane mode)
Front Antenna -- front antenna ON/OFF
Rear Antenna -- rear antenna ON/OFF
RANGE (5 increments)
VOLUME (8 increments)
SQL -- squelch or unsquelch (audio)
TEST -- Self Test
OPTION -- set parameters (e.g. audio alert)
Selectable audio: proportional to target speed or combined speed (target plus patrol car)
PWR -- ON/OFF (defaults last operating parameters)

DISPLAYS / INDICATORS (LEDs)

Display -- Target Speed STATIONARY MODE
10 or 15 to 210 mph (16 or 24 to 337 kmh) MOVING MODE (on-coming traffic)
10 or 15 to 210 mph (16 or 24 to 337 kmh)
210 mph max closing speed SAME-LANE / DIRECTION target
± 2 mph (± 2 kmh) to 75% of patrol car speed
patrol car speed must be 20 mph (32 kmh) or greater to acquire targets
target speed must be at least 2 mph (2 kmh) slower or faster than patrol car speed
Display -- Locked (target) Speed
Display -- Patrol Car Speed
5 to 100 mph (8 to 144 kmh)
Indicators (messages)
RFI -- Radio Frequency Interference
Low V -- Low Voltage
TEST PASS -- Self Test Passed
Displayed During Self-Test
- ROM PASS -- Read Only Memory checksum ok
- RAM PASS -- DSP Random Access Memory ok
- DSP PASS -- DSP Passed Self Test
SYS -- System Error, remove from service
Ant? -- Antenna NOT connected
Rmt? -- Hand remote NOT connected
