1. INTRODUCTION
The DT360Xi is an advanced high-speed, high-resolution multibeam echosounder system (MBES) that has the
capability to scan in a 360° arc with an along-track transducer beamwidth of 0.7°. Its primary use is for
applications that require all-round profile points for example internal bores, pipelines, flooded structures and
caves and caverns.
The system consists of an underwater sonar head connected by an Ethernet cable to a surface personal
computer (PC). A top-side power supply supplies operational power via the same cable.
The effective beamwidth is selectable at 0.75°, 1.5° and 3° and the number of beams are selectable at 360,
720 and 1440 beams. Data is acquired at full resolution every shot but processing the data for screen display
on a PC can slow the system at highest number of beams. 360 Beam mode is therefore recommended for real
time data acquisition and data can then be played back at the high-resolution of 1440 beams.
The general features are:

2. GETTING STARTED
The DT360Xi was designed to be user friendly and simple to set up. The following paragraphs detail the
recommended considerations and set-up:
2.1. HARDWARE INSTALLATION
It is recommended that the 4 X mounting holes be used to secure the sonar to a retaining frame
(highlighted in red below). The transmitter and receiving transducers should be clear of any obstruction
and have a clear view of any targets:
Figure 1 Mounting Arrangement
The sonar is designed to be mounted in the horizontal plane with the sonar scanning vertically, but may
be mounted vertically with horizontal scanning.

Ensure 24 (22 –32) VDC @ 1 A minimum power supply is connected but remains off.
Connect the RJ45 connector to the PC’s network port or USB to Ethernet adapter.
Connect the underwater connector to the sonar.
Power up the DT360Xi.
Configure the IP address in Windows™ see 2.2 Software Setup.
Launch the DT360Xi_vxxxx.exe program.
The minimum requirements for the user supplied PC are:
Intel i5 or equivalent.
Windows™ 7.
8 GB RAM.
Available discreet Gigabit Ethernet port, supported by a Realtek PCIE GBE family chipset (not an FE
family chipset). If an external Ethernet to USB adapter is used, a high specification USB 3.0 Gigabit
Ethernet Adapter is recommended. The TP-LINK Model UE300 appears to work well.
Minimum software screen resolution is 1024 x 768.
1 TB Hard drive.
2.2. SOFTWARE SETUP
The sonar head needs to run with a static IP (Internet Protocol) address for both head and PC. The IP Address
of the PC must be set to 192.168.0.X where X is any number between 3 and 254. The subnet mask is set to
255.255.255.0. These settings can be found in the ‘Network Connections’ item in the ‘Control Panel’.
The IP Address of the sonar head is fixed at 192.168.0.2.
See APPENDIX B Ethernet Setup Guide.
The software runs on a PC via an executable file DT360Xi_vxxxx.exe where xxxx is the version number. The
latest version is available on the Imagenex Technology Corp. website (https://imagenex.com/interior-
page/software-download). Associated with the executable file is an INI file, which is automatically created upon
start-up if not present in the folder used to run the executable. This file holds the settings of the program and
reloads them subsequently.

2.2.2. Controls:
Range (Real-time only). Range is adjustable between 0.5m and 10m and sets the expected maximum range to
target. It should be monitored and adjusted according to the expected target distance from the sonar.
S Gain (Real-time only): Gain can be set between 0dB and 20dB. Sets the gain value of the sonar. It should be
monitored and adjusted according to propagation conditions, range to target, ambient noise and other such
factors. Adjustment should be made when the sonar is in High Mix mode (see section 3.9.1 Profile > Profile
Mode), as this mode displays intensity and gives a better indication of the saturation levels of the internal
receivers.
Recommended value: Start at 5 dB and adjust up or down. Optimum when sufficient returns but not saturated
D Gain: Adjust the display threshold so that sufficient data is displayed and no saturation of the display occurs.
Adjustment of Display Gain does not impact the recorded data nor the sonar return performance. It is only
used to optimise the display saturation.
Recommended value: 50% during data acquisition
Zoom: Zooms the display in and out between 50% (zoomed out) and 300% (zoomed in). This allows the user
to zoom in to features of interest.

2.2.3. Displays
Range and resolution (top left): Displays the range and resolution set.
Date, time and recording status are displayed (top right).
R: Displays the cursor distance in metres from the sonar transmitter.
B: Displays the bearing between the cursor and the zero angle plain. Zero angle is the vertical +Y axis of the
display.
D: Displays the sonar distance along track (sometimes called chainage). Comes from the Cable Counter input
value. (see 3.11.2 Options > Cable Counter Input….). Note that this value may also pertain to Depth if the
sonar is being deployed vertically for example into a borehole.

Connects to the sonar head.
3.1.2. File > File Playback
Data can be replayed from a previously recorded file from the Open File Dialog.
3.1.3. File > Record (.IGX Format)
Records an IGX format file to the path and filename specified in the Save Dialog. A default file name is
generated based on date and time, but this may be changed. It is recommended that during operations, IGX
files are logged throughout. This will be beneficial during support if required.
3.1.4. File > Record (B96 Format)
Not implemented
3.1.5. File > Record (P96 Format)
Not implemented
3.1.6. File > Stop Recording
Stops the recording process.

If enabled, Sets the maximum file size to 1,2,3,4 GBytes.
3.1.8. File > Convert .IGX to .xyz
The user specifies a previously logged .IGX file and a points cloud file is created with each point having an X,
Y and Z coordinate. The X and Y points are derived from a simple polar to rectangular conversion using the
scan angle and range data, and the Z is incremented by the cable counter input.
The generated XYZ file is a (tab delimited text file) with format as follows:
PC Date<tab>PC Time<tab>X<tab>Y<tab>Z.

3.3. COLOUR TABLE
Allows various colour combinations (background and scan) to be selected.
Used to change the sonar data colour palettes for the sonar images. DT360Xi uses a colour table to represent
echo data strength (amplitude). For example, the Normal High intensity colour table maps the echo data
amplitude to 256 colours ranging from black (low strength level) through blue, green, orange, yellow, white,
and red (highest strength level).
The Colour Table menu offers the following options:
Normal High
Standard colour table used for mapping the echo data amplitude to 256 colours ranging from
Black (low level), through blue, green, orange, yellow, white, and red (highest level)
Normal Low
Same colours as Norm Hi, but uses a lower colour intensity
Green
256 shades of green
Grey
256 shades of grey (white on black)
Reverse Grey
256 shades of Grey (black on white)
Brown/Yellow
256 mixed shades of brown and yellow
Green/Blue
256 mixed shades of green and blue
Green/Yellow
256 mixed shades of green and yellow
Blue
256 shades of blue

3.4. MODE
3.4.1. Mode > Polar
Displays a polar plot with targets and return intensities.
3.4.2. Mode > Beam Test
Displays the beam test widow showing return from all channels. Not used in normal operations.

3.5. DATA POINTS
Select 500 or 1000 data points.
3.6. BEAMS
Select 360, 720 or 1440 beams for display. Data is acquired at full resolution every shot but processing the
data for screen display on a PC can slow the system at highest number of beams. 360 beam mode is
therefore recommended for real time data acquisition. The data can then be played back at highest resolution
(1440 beam).
3.7. BEAM WIDTH
Select:
Processed 1 –3°
Processed 2 –1.5°
Processed 3 –0.75°
3.8. AVERAGING
This selection is useful in the elimination of spurious returns. Depending on selection (Off, 3 shots, 5 shots, 7
shots or 9 shots) returns are averaged and the average value plotted. Spurious outliers are thus removed. The
value selected will affect the speed of plotting as the sonar will be required to wait for for example 3, 5, 7 or 9
shots (dependent on selection) to be returned before plotting, which will adversely affect speed.

3.9. PROFILE
3.9.1. Profile > Profile Mode
One of the following can be selected:
High Mix: Image data is displayed at the normal intensity along with the generated profile points.
Med Mix: Image data is displayed at the half intensity along with the generated profile points.
Low Mix: Image data is displayed at the quarter intensity along with the generated profile points.
Points Only: Image data is not displayed. The generated profile points are displayed.
3.9.2. Profile > Profile Point Filter
One of the following filters can be used:
First Return: Displays the first return received. This may include return from items in the water column
and may not represent a true target.
Maximum Return: Displays the target with the maximum intensity received during the receive window.
This is the recommended setting.
Bottom Following: Displayed points are based on neighbouring points in order to generate a smooth
contour. Objects in the water column which generate weaker returns will not generate profile points.
3.9.3. Profile > Profile Min Range …
Allows the user to set a gate where any returns with a range less than the gate set, are not plotted nor logged.
This is useful in eliminating spurious returns if the target’s approximate range is known, but should be used
with caution.
3.10. DATA OUTPUT
It is possible to output point and beam data on a UDP port for use with additional software. The format (P96 -
Point Data or B96 - Beam Data) and the UDP Output IP are selected. Note that if the same PC is used to run
both DT360Xi and the third party software, a loopback IP (127.0.0.1) should be used. Port =4040
3.11. OPTIONS
3.11.1. Options > Sonar IP Address…
Realtime only. The Sonar has a default factory setting of 192.168.0.2. If during the ordering of the sonar, a
different IP address was requested, the non-default address may be set here.

DT360Xi Multibeam System
Doc No: 430-053-00 Page 20 of 37
3.11.2. Options > Cable Counter Input…
Realtime only. A cable counter may be integrated to allow for computation of the distance or depth value. The
cable counter must be interfaced via a COM port and the port and baud rate are set. The expected format of
the cable counter string is $xx.x,meter<CR><LF>, where xx.x is decimal meters.
3.11.3. Options > Diagnostics…
This opens the diagnostics window that displays data from the sonar head. This includes Format, Operations,
Speed and Environmental data.
3.11.4. Options > Sonar Information…
This opens the sonar information window that displays additional data from the sonar head.
3.11.5. Options > Sonar Orientation
Realtime only. This allows the user to specify the orientation of the transducer relative to the direction of travel.
If the transducer array is forward with respect to the direction of travel, ‘Transducer Fwd’ is selected and if aft
with respect to direction of travel, ‘Transducer Aft’ is selected.
A mounting angle can also be set (between -180° and +180°). This is used to the rotate the sonar image by
the mounting angle set in the case that the sonar body is not mounted horizontally.
3.11.6. Options > Sound Velocity…
If sound velocity is known, it can be entered here and the ranges will be adjusted accordingly. If unknown, the
default of 1500m/s should be used.
3.12. HELP
Displays a dialog with the version number which should be quoted during support requests.
