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.

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 Measure – Ready (9, Fig. 2) is displayed

15

 Quick link to the Standard1 set of measurement parameters

(display name: Std1),

 Quick link to Standard2 set of measurement parameters

(display name: Std2),

 Setup mode (display name: COdE),

 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.

Empty field means the parameter is not measured in this mode, NC

means ‘no change’ to the measurement parameter setting.

Once set, the mode parameter is stored in on-board memory and

will be kept current until reset in the Setup mode.

Choosing Cd 16 in the Setup mode will cause all display

segments and indicators to flash for 8 seconds. Flashing can be

interrupted by pressing either button.

19

Compass calibration

If the Module was exposed to a strong magnetic field or was not

in use for a long time, the compass accuracy may diminish.

To bring the compass into working condition:

 Select Cd 17 in the Setup mode

 Keeping the unit horizontally, perform one full rotation

around vertical axis within half a minute and then one full

rotation around vertical axis with device upside down

during half a minute.

 If one rotation does not restore calibration – perform two

rotations.

The normal compass functioning will be restored.

Depending on the version of the on-board software, during

calibration LCD will show either time countdown in seconds

from 59 to 1 or flashing word CAL.

To ensure azimuth measurement accuracy calibrate compass

after changing the battery.

Interface format

The unit can output measurement data via RS-232 port in either a

proprietary protocol or in the format accepted by PLGF/DALGR.

The selected format will be indicated on the LCD with display

names PLGr or -PC-.

To select the required data transfer format:

 Select PLGr (-PC-) in the Setup mode

20

 Pressing the A button will activate shown on the LCD

communication format.

Gating mode

In this mode the gating function is activated: user can set the

minimal distance to the target; reflection from any object closer

than the gating distance will be ignored.

The Gating feature helps measuring remote targets in adverse

atmospheric and environmental conditions by eliminating

reflections from snowflakes, raindrops, industrial wires,

branches, etc. At the same time, if gating distance is set

incorrectly, you can remove the desirable object from

measurement range.

To enter the gating mode press the A button when GAt is

displayed. Minimal gating distance of 100 m will be initially set,

further pressing the M button will increase gating distance by

100 m up to 7,000 m. When the desired distance is reached –

select it by pressing A button.

The Gating distance can potentially be set longer than the

maximum measuring range. The device will not measure

anything then. To deactivate gating choose one of preset modes

that do not include gating (for example: Standard1, Standard2,

Code1, Code2, etc.).

Note: the Gating distance can only be increased. To exit gating

selection cycle without setting any gating distance press the M

button 70 times or hold the M button for 2 seconds.

21

Data Recall mode

In the Data Recall mode results of the last 10 measurements can

be displayed.

Measurement results are saved in on-board memory in sets

depending on the parameters set for measuring, for instance, if

only distance is measured - the set will consist of one number, if

distance and azimuth are measured – the set will consist of two

numbers.

To enter the Data Recall mode press the M button in the Ready

to Measure mode until rEc is displayed and then press the A

button. First measurement set number (display name: rEc 1)

will start flashing.

Pressing the M button moves the unit along the list of

measurement set numbers and measurement results:

rEc 1, distance 1, azimuth 1, elevation 1,

rEc 2, distance 2, azimuth 2, elevation 1, …,

rEc 0, distance 0, azimuth 0, elevation 0.

Measurement sets are numbered in reverse order: first recalled

set is the result of the last measurement. If any parameter has not

been actually measured it will not be recalled.

Pressing the A button at any moment within the list of recalled

results (or pressing the M button at the end of the list) brings the

unit to the Ready to Measure mode.

Choosing cLr in the Setup mode will erase all measurement

data.

22

Display test mode

Selecting Code 16 in the Setup mode will cause all display

segments and indicators to flash for 8 seconds.

Additional display information

Additional indication is displayed in the Ready to Measure

mode:

Y or M Indicates that distance is measured and

displayed in yards or meters

KMH or

MPH

Indicates that speed is measured and displayed

in km/h or mph

° Indicates that only azimuth is measured

° Indicates height in meters or azimuth is mils

measured

OVER 100M – indicates that gating is active

Laser active indicator (6, Fig.2) flashes, when unit emits laser

radiation. Reliability of ranging depends on the number of pulses

that reflect from the target and reach the unit. Module informs

user about the number of received pulses by a message on LCD:

TARGET REFLECTION LOW – ranging results have low

statistical reliability,

TARGET REFLECTION MED – ranging results have

medium statistical reliability,

TARGET REFLECTION HIGH – ranging results have high

statistical reliability.

23

6. BEST MEASURING TECHNIQUE

Laser range finder module measures distance by catching a laser

beam reflected from the target. Everything that improves

reflection increases the measurement reliability and maximum

range.

1. Aim at a surface on the target that is closest to the

perpendicular to the laser beam. The closer you get – the

stronger will be the reflection.

2. The unit deploys sophisticated software that tries to

understand which target you are aiming at. However, due to

beam divergence several objects may produce a strong

reflection. To help the system recognise the target the Target

Selection Logic may be used. For example, if ranging a wire

in front of a building, selecting the “first” target (Code 12)

will produce a more reliable result. Alternatively, when

aiming at a chimney behind the trees, selecting “last” target

(Code 11) will be better. By default the System assumes

“auto” target selection, that is, the object producing the most

reflections will be considered a target.

3. Another way to improve reliability of measurement is to use

the gating mechanism. When gating is active reflections

from all objects closer than the gating distance will be

ignored. This is especially effective when ranging in

unfavourable atmospheric conditions, that is, in the rain, fog,

haze or bright sun. Gating provides better results than the

“last” target selection, but it requires preliminary rough

24

distance estimation to cut off all objects closer than the

chosen one.

Note: the Gating setting is remembered by the System until

altered. Therefore, if you forget to turn the gating off, the next

time you start measuring it can ignore the desired object, if it is

closer than the gating distance. The unit will display four dashes

instead of the measurement results. “Over 100 meters” display

indicator shows active gating.

25

7. Interconnectivity

The unit supports RS-232 interface. Physical connection is

performed through a connector specific to each order. The

default connectors are described in Specifications.

Connecting to computer

The communication port must be initiated prior to connecting the

unit.

Data is transmitted as a hex string code with fixed baud rate of

9600 bit/sec, 8 bits, one stop bit, and no parity.

If the port is connected and not initiated, the module will be

activated immediately in scan mode.

Data output protocol

This physical interface uses one line to an external UART

(Universal Asynchronous Receiver / Transmitter) port. The data

is transferred in accordance with the serial asynchronous

communications protocol, known as the RS-232.

A typical UART frame is shown below. It comprises a Start bit, 8

data bits, and a Stop bit.

Along with the data transfer line the RS-232 port includes signal

lines, used to control the module.

26

The data string has the following structure (in Hex):

b1 b2 b3 E4h b5 E4h 0Dh 0Ah,

where:

b1 – type of measurement;

b2 – sign of measurement (1 – minus, 2 – plus);

b3 – LSB of result;

b5 – MSB of result

Result of measurement = MSB * 256 + LSB

In both standard modes, when three parameters are measured, the

module will generate three data sequences in one block, where

the first one presents results of distance measurement, the second

– results of azimuth measurement, the third – result of inclination

measurement.

The data string will look like:

b1 b2 b3 E4h b5 E4h

b7 b8 b9 E4h b11 E4h

b13 b14 b15 E4h b17 E4h 0Dh 0Ah

Where bytes contain the following information:

b1, b7, b13 – type of measurement

b2, b8, b14 – sign of measurement (1 – minus, 2 – plus)

b3 – LSB of the result for the first type of measurement

b5 – MSB of the result for the first type of measurement

b9 – LSB of the result for the second type of measurement

27

b11 – MSB of the result for the second type of measurement

b15 – LSB of the result for the third type of measurement

b17 – MSB of the result for the third type of measurement

Marker E4h is used to separate numbers, 0Dh 0Ah – to separate

data sets.

Type of measurement (bytes b1, b7, b13) can have the following

value:

1 – Distance in meters

2 – Distance in yards

3 – Azimuth in degrees

4 – Azimuth in mils

5 – Elevation in degrees

6 – Elevation in mils

7 – Elevation in meters

8 – Speed in km/h

9 – Speed in MPH

Additional communication features, for special

orders only

Module sends its menu status to the interface every time the

“Mode” button is pressed.

The mode state string has the following structure (in Hex):

S1 S2 S3 S4 0Dh 0Ah,

where

28

S1 – first symbol of the status menu

S2 – second symbol of the status menu

S3 – third symbol of the status menu or 21h

Output connector pin layout and cable diagram

By default for the output connector the module uses the

connector as described in Specifications. This connector

withstands high environmental loads and is designed for outdoor

usage.

30

Figure 4. Cable diagram

Connector and cable layout can be modified for specific

customer needs.

GPS interconnectivity

The Modules can transmit the acquired data to a GPS receiver

using the same output connector and the PLGR/DAGR protocol.

31

Another cable is required and can be supplied as an option.

To work with GPS, perform the following steps:

 Switch to PLGr mode;

 Choose either Std1 or Std2 measuring mode;

 Connect the unit to and the GPS unit with the cable.

For each measurement the GPS unit will display the absolute

coordinates of your target.

Note: If the module is not set initially to the Std1or Std2 modes,

GPS connection will not operate properly.

Note: The GPS unit automatically adjusts coordinates to reflect

actual magnetic declination. Therefore, coordinates

displayed on the GPS may differ from those calculated by

the computer.

32

8. STORAGE AND MAINTENANCE

The unit is a sophisticated precision optical instrument equipped

with laser and electronics. Therefore, it should be handled with

due care.

• Keep away from direct sunlight.

• Avoid impacts, jolts, dust, moisture, and sharp changes of

temperature.

• Do not use the device at temperatures higher than 50oC
