1. Overview
The manual references embedded software version V1 R1. To see which software version is
installed on your system, see the Swipe Down menu in Section 3.4.
The LMX150™FINDAR®is a complete Ground Penetrating Radar system, offering two modes
for acquiring data: Line Scan and Grid Scan. Once the unit is assembled and powered-up, you
can start conducting a GPR survey in less than a minute.
Features of LMX150™FINDAR® include:
•High visibility, touch screen display
•Display depth slices from collected grids, right in the field
•UWB (ultra-wide band) Antenna producing highest data quality
•Lightweight fibreglass cart frame
•Built-in Wi-Fi capability
•Integrated GPS receiver with optional external GPS for increased positional accuracy for
geo-referencing data
•Ability to mark surface flags and subsurface interpretations directly in the data
•Display your travelled path and targets in Map View
•Seamless export of data to EKKO_Project™software for further data analysis
This manual describes the operation of the LMX150™FINDAR®system and collecting GPR
data. There is also a section that describes the basics of GPR theory and techniques for proper
surveying.

2. Assembly
2.1 Out of the box
You will find the following components in your box. Some of these may already be assembled.
Attach the Cart Handle to Cart Base using the Handle Pins. Ensure the Display Unit Tray is
facing the operator.

Assembly
14
Attach the GPR Sensor to the Cart using the Sensor Support Straps. Ensure the Sensor is
oriented the correct way with the connections toward the back of the Cart. Using the Sensor
Support Straps, adjust the height of the Sensor so it is 1-2 cm (½ –¾ inch) above the ground.
The best way to get a uniform Sensor height is to place a couple of sheets of thick cardboard,
particle board or Styrofoam under the sensor before securing the Sensor Support Straps.
Note that the straps come in two different lengths. The 2 shorter straps attach at the front, and
the 2 longer straps attach at the rear.
Attach the Display Unit onto the Display Unit Tray on the Cart. The Display unit slides down into
the tray, catching on both sides of the mount and is held in place with the pull pin. When a click
is heard, the Display Unit is firmly in place. Adjust the angle of the Display Unit by loosening the
hand-screws underneath the Display Unit Tray, rotating the Display Unit to the desired angle
and tightening the hand-screws. To remove the Display Unit, pull out the pull pin and lift the
Display Unit up.

Assembly
15
Attach the Display Cable to the back of the Display Unit with the jackscrews.
Connect the other end of the cable to the Sensor. Ensure the cable is routed as shown below.

Assembly
16
Set the battery onto the inclined shelf on the back of the cart. Align the Velcro on the battery to
the Velcro on the cart. Secure battery by fastening the plastic buckle and tighten straps if
necessary. Attach the Odometer and Battery Cables. The Odometer Cable connects from the
odometer to the closest receptacle on the Sensor. Attach the Battery Cable to the Sensor and
the other end to battery.

Assembly

2.2 External GPS (optional)
The instructions for connecting the GPS, mount and cable are below:
GPS Mount –The GPS mount attaches to the crossbar frame above the battery, using a quick
release pin. There is a pipe plug that needs to be removed first.
Once that is done, ensure the pole is pointed up, then insert the GPS mount into the opening
where the plug was removed and secure with the quick release pin. This allows the GPS to sit
directly over the middle of the GPR sensor. It comes with 5/8-11 UNC-1A threads at the top of
the pole, which is standard for many GPS receivers.
GPS –If you have purchased the Trimble AG-200 GPS from Sensors & Software, this can be
screwed onto the threads at the top of the GPS mount. Ensure that you use the cable labeled
AG-200 that comes with the Trimble GPS; do not use any other cable, as the internal wiring is

different and could damage the Trimble AG-200 GPS. Connect the 90oend of the GPS cable to
the GPS receiver, and the other end to the serial port on the back of the display unit. This
single cable powers the GPS and receives data from it. Ensure that the Display Unit is powered
down when connecting or disconnecting the GPS cable.
If you choose to connect a 3rd party GPS receiver, you must ensure the following parameters
are set for the GPS to communicate with the Display Unit:
- Baud rate = 19200 bps
- Output string = NMEA
- NEMA string must include $##GGA
- Parity = None
- Stop Bits = 1
- Data Bits = 8
NOTE: Since the serial port of the Display Unit outputs power (current=1A, voltage=12V), be
very careful if connecting other GPS units to the serial port. Verify the pins on the drawing
below.

2.3 Fully Assembled
The fully assembled LMX150™FINDAR®will look like the following. Simply reverse directions
to disassemble for transport.
