1. BRIEF DESCRIPTION
The LRF Modules use the same electronics and optics as
rangefinder monoculars and binoculars. These modules can add
various range finding capabilities into host systems: distance &
speed measurement, azimuth and elevation measurement.
The modules have a built-in computer interface, which enables
immediate data acquisition by any system with standard serial
interface. Depending on exact model, customer has a choice of
various incorporated features, including, but not limited to gating
capability, fast scan mode, speed measurement, object selection
and more.
Typically a rangefinder module becomes a part of:
- Thermal imagers
- Day/night surveillance systems
- Airborne optical systems.
Both modules can be integrated into a bigger observation system.
The Modules comply with CFR 21, Part 1040.10
4
Principle of work
The Modules send invisible, eye safe laser pulses to the target.
Pulses reflected from the target are captured and processed by the
digital circuitry. The time-of-flight delay between the sent and
received pulses allows calculating the distance to the target.
A built-in digital compass/inclinometer of MOD 4EC measures
target’s azimuth and elevation simultaneously with ranging.
Key Features
Selection of the first, last or the most reflective target
Distance is displayed in meters or yards, speed is displayed
in km/h or MPH, azimuth and elevation are displayed in
degrees or mils
Original digital circuitry allows ranging through most types
of glass, bushes and other obstacles
Two reticle shapes: -¦- or
Built-in digital accurate compass/inclinometer, angles are
displayed in degrees or mils.
On-board memory keeps results of the last 10 measurements,
that can be recalled

5. OPERATION INSTRUCTIONS
Maximum distance
Though maximum measurement distance depends on target
reflectivity, weather conditions and other conditions, for most
targets the unit will provide accurate ranging for up to 3,000
meters. In good conditions a highly reflective target can be
measured up to 4,000 meters.
Target reflectivity depends on its color, surface finish, size,
shape, position in relation to the laser beam, etc. Bright target
colors are more reflective than dark ones. A polished surface is
more reflective than a rough one. Larger targets reflect better
than small ones. Ranging a target perpendicular to the laser beam
provides better results than the one positioned under a sharp
angle to the beam.
Weather conditions that influence air transparency (rain, fog,
snow, mist) reduce maximum range. Bright sunny days will
reduce performance as well, as IR sun radiation may cover
reflected laser pulses.
While the unit will measure through many glass types, measuring
through glass may reduce accuracy and range.
Module controls
Modules can be fully controlled via RS-232 connector and/or
with buttons on remote control. The control procedures are
identical and interchangeable.
11
The correspondence between the pressing of the buttons and the
signals sent via RS-232 is described in Interconnectivity, chapter
7.
The rest of this manual describes measurement procedures and
setting measurement parameters through pressing of the buttons.
Measurement procedure
When the Module is off the LCD is blank. To activate it press
and hold for one second the Action (A) button. At start the
module comes into the Ready to Measure mode indicated by the
word ‘READY’ on the display.
Pressing the Action button in the Ready to Measure mode
initiates measurement. The result of the measurement is
displayed in a form that depends on the measurement parameters
(see Setup Mode).
Note:
If more than one parameter is chosen to measure, e.g.
distance and azimuth, the results will replace each other on
the display every half a second.
If the target is located below the unit the result of vertical
measurement (elevation or height) will be preceded with
minus (“-“) sign.
If results of angular measurements can not be interpreted by
the unit an error codes 444 (for azimuth) or 99 (for
elevation) will be displayed. Repeat the measurement. If
error codes appear again – reboot the unit by switching it off
and on again.
12
Target selection logic
On its way towards the target, laser beam may reflect from
various objects, thus decreasing ranging accuracy. The smaller,
the farther, and the less reflective is the target – the higher is the
possibility of obtaining an incorrect measurement.
To improve accuracy the unit has a built-in target selection logic,
which allows choosing what target to range: the nearest (‘first’),
the farthest (‘last’), or the most reflective (‘auto’).
This mechanism helps selecting the target when ranging from
behind the bushes, wires, through the falling snow, or in similar
conditions. Similarly it enables ranging a target in front of a
bigger object, such as a wire in front of the wall.
Note: Even with target selection logic the unit may not always be
able to range the desired target as its reflectivity may be too low
to produce enough laser beam reflections for statistically reliable
calculation. A warning will be displayed if result is not
statistically reliable. See more about target reflectivity in
Additional display information (0). This information will not be
transferred via RS-232.
Individual Measurement and Scanning regimes
The unit can operate in two regimes: (1) Individual Measurement
and (2) Scanning. In the Individual Measurement regime the unit
performs single measurement when the A button is pressed
shortly, in the Scanning regime the unit repeatedly measures and
displays results every second while the A button is pressed.
13
To activate the Scanning regime press and hold the A button in
Ready mode. The unit will work in the Scanning regime while
the A button is pressed.
Scanning or Individual Measurement regimes are available for
any selected mode of measurement. When two parameters are
measured in the Scanning regime though both will be quickly
displayed, the second one may be difficult to register by eye.
Nevertheless all data is recorded and may be recalled (see Data
Recall mode for details.)
Operation and service modes
The unit has the following modes of operation:
Ready to Measure – to perform measurements
(Quick link to the Standard1 and Standard2 sets of
measurement parameters appears in mode selection
menu for convenience and does not constitute a separate
mode)
Setup – to modify the Ready to Measure mode parameters,
Gating – to set a minimum distance of measurement,
Data Recall – to recall the last 10 measurement results,
Data Clearance – to clear measurement results.
In the Setup mode four parameters of measurement can be set;
these parameters define:
1. What the unit measures: distance or azimuth or elevation or
all measurements at once,
14
2. In what units result of distance measurement is displayed:
meters or yards, degrees or mils, km/h or mph,
3. What reticle shape is visible: rectangular or crosshair, and
4. Which target is selected: first, last or most reflective (see the
Target selection logic (5.4) for more details).
The Setup mode is described in more detail below.
The unit has two standard sets of the Ready to Measure mode
parameters:
Standard1: distance is displayed in meters, azimuth and
elevation are displayed in degrees, crosshair reticle is
visible, auto target selection is used,
Standard2: distance is displayed in meters, azimuth and
elevation are displayed in mils, crosshair reticle is visible,
auto target selection is used,
Code 8 sets the same set of measurement parameters as the
Standard1, except for distance measurement in yards.
At start the unit assumes the Ready to Measure mode with
measurement parameters inherited from the previous setup. At
manufacturing stage the unit is set up into Standard1 set of
measuring parameters.
Mode switching and tuning
Pressing the Mode (M) button in the Ready to Measure mode
switches the unit between modes of operation:
Ready to MeasureReady (9, Fig. 2) is displayed

Gating mode (display name:
GAt),
Data Recall mode (display name:
rEc),
Memory Clearance mode (display name:
cLr),
Interface selection mode (display name:
-PC- or
PLGr).
Flashing display name indicates the mode which can be selected
by pressing the A button.
The Setup, Gating selection, Data Recall and Interface selection
modes have submenus, so when the A button is pressed to select
these modes the unit automatically enters the corresponding
submenu. In the same way as with the mode switching, the M
button switches between the submenu items and A selects the
needed one. When the A button is pressed from the submenu the
unit comes into the Ready to Measure mode with the selected
parameter.
If no button is pressed for 8 seconds the unit leaves the current
mode, in the Ready mode it switches off. Next time the unit is
turned on it assumes the last chosen combination of the four
Ready to Measure mode parameters.
16
Note: On a special request a menu of a particular unit can be
simplified to show only required modes.
Setup mode
To modify the Ready to Measure mode parameters:
Enter the Setup mode.
With word Ready on the display press the M button till
display name
COdE is displayed and press the A button.
Select the desired parameter modification (see table below).
Press the M button till the code name of the desired
parameter is displayed and press A button.
To leave the Setup mode without changing measurement
parameters press and hold the M button for two seconds. This
works like the computer Esc key. The rangefinder will then keep
the last set of parameters and return to the Ready to Measure
mode.
