WARNING

CLEANING INFORMATION

Before cleaning any external parts of the apparatus, make sure

that all cables have been disconnected, including the power

supply cable. If a damp cloth is used, make sure it is not too wet,

to avoid any damage to the electrical components of the

equipment. Wait until the equipment is totally dry before

reconnecting the cables.

The Opera Duo should be cleaned periodically using a damp

cloth.

Do not use solvents or abrasive detergents.

Do not apply liquid directly to the electrical contacts of the

various connectors. If a specific spray is used to clean the PC

TFT monitor, make sure it is not flammable; in any case, do not

spray it directly on the screen, instead, spray it onto the cleaning

cloth.

compliance could void the user’s authority to operate the equipment.

Operation of this device is restricted to law enforcement, fire and rescue officials, scientific research

institutes, commercial mining companies, and construction companies. Operation by any other party is a

violation of 47 U.S.C. § 301 and could subject the operator to serious legal penalties.

Coordination Requirements.

(a) UWB imaging systems require coordination through the FCC before the equipment may be used. The

operator shall comply with any constraints on equipment usage resulting from this coordination.

(b) The users of UWB imaging devices shall supply detailed operational areas to the FCC Office of

Engineering and Technology who shall coordinate this information with the Federal Government through

the National Telecommunications and Information Administration. The information provided by the UWB

operator shall include the name, address and other pertinent contact information of the user, the desired

geographical area of operation, and the FCC ID number and other nomenclature of the UWB device. This

material shall be submitted to the following address:

3. OPERA DUO HARDWARE DESCRIPTION

The Opera Duo system is composed by the following parts:

 Opera Duo main body

 Laptop (with the Opera Duo software)

 Battery

 Battery charger

 Spray support (optional)

 GPS support (optional)

This chapter contains the description of those parts.

3.1 Opera Duo main body

The main body of the system consists of a trolley, foldable for easy transportation,

available in two forms: 2 or 4 wheeled; it contains the following sub-components:

 Antenna

 Control unit

 Encoders

 Handle

 Wheels

 Laptop support

3.1.1 Antenna

The Opera Duo has a dual-frequency antenna, 250 and 700 MHz.

The 700 MHz antenna permits the user to see small shallow targets, up to a depth 2-3

meters depending on the soil conditions.

The 250 MHz antenna permits the user to see bigger targets situated deeper underground

(up to 4-5 meters).

3.1.2 Control unit

The Control Unit, or DAD, is the central part of the system because it communicates with

the antenna, the laptop and the encoder, making all the systems work together.

The DAD is lodged in the antenna box and has a power button on top of it to turn it on/off

(see Fig. 3.1).

The characteristics of the Control Unit are:

Voltage: 12 V +/- 10%

Environment feature: IP 65

Absorbed power: 8 W

Operating temperature: -10/+40 °C

Fig. 3.1 – DAD power button

3.1.3 Encoders

The Opera Duo employs two encoders for acquisition distance measuring, each one is

positioned inside one of the wheels.

This feature ensures that the distance is correctly registered even in rough terrain when, at

times, only one wheel is touching the ground.

4. ASSEMBLY PROCEDURE

The procedure to assemble the Opera Duo is very simple and can be performed by one

person.

To assemble the system follow these steps:

1. Unfold the radar main body (paragraph 4.1);

2. Connect the laptop (paragraph 4.2);

3. Insert the battery (paragraph 4.3);

4. Mount the Spray support (optional, paragraph 4.4);

5. Mount the GPS support (optional, paragraph 4.5).

4.1 Unfold the radar main body

To unfold the Opera Duo main body place it to on the ground, press the central handle

button and raise the rudder to the desired angle (Fig. 4.1).

The user can also adjust the height of the handle bars and laptop support using the two

vertical buttons in the upper part of the rudder (Fig. 4.2).

Fig. 4.2 – Handle bar and laptop support height regulation buttons

The inclination of the laptop support can be changed opening the two horizontal locks on

its sides (Fig. 4.3).

In the 2 wheeled version, the antenna movement has to be unlocked by putting the front

lever in the left position (Fig. 4.4); if the lever is in the central position the antenna will

have limited mobility, useful for rough terrain; while the right position is used for the

transportation of the folded system.

In the 4 wheeled version, the antenna can be slightly raised from the ground by pulling the

strap shown in Fig. 4.5.

4.2 Connect the laptop

The laptop support on the radar main body is complete with Velcro strips; to attach the

laptop to the support press down until the Velcro strips on the support are securely

attached to the Velcro strips on the laptop (see Fig. 4.6).

Fig. 4.6 – Velcro strips on the Laptop and Laptop support

The CF-H2 laptop provided with the radar already has the Velcro strips attached; if

another laptop is used instead, the user should attach the Velcro strips (provided with the

radar) to this laptop.

Once the laptop is in place the user must connect the Ethernet cable (Fig. 4.7).

4.4 Mount the Spray support

The Spray support is an optional component to hold and command the spray to mark

targets on the ground.

It can be mounted on either side of the antenna, following these steps:

1. Open the locks in the lower part of the spray support (Fig. 4.10);

Fig. 4.10 – Spray support locks

2. Fix the spray support to the radar main body, inserting first the upper part and

then the lower (Fig. 4.11);

4.5 Mount the GPS support

The GPS support is composed of two metallic parts whose purpose is to hold the GPS

pole. This pole is not provided with the radar.

To mount the GPS support follow these steps:

1. Insert the upper part of the support into the two dedicated holes (Fig. 4.14);

Fig. 4.14 – GPS support upper part insertion

2. Screw the lower part to the Opera Duo main body using the two knobs, in this

way the two parts will be fixed together (Fig. 4.15).

4.6 Encoder calibration

The first time the system is used the metric wheels have to be calibrated; this operation

can also be repeated every time a difference between real and measured distance is noted.

First the user should inflate the tires to a pressure of 2 bars, then proceed with the wheel

calibration using the proper software tool (see paragraph Error! Reference source not

found.).
