Attach the supplied USB cable to the Odom Digibar-V topside port labeled USB and the other end to any available USB port on the acquisition PC, this supplies power to the SVS and also communication from the SVS to the PC, as COM 5

PC Network SettingsPC Network SettingsThe Benthos C3D sonar connects to Isis via an Ethernet connection. The default IP address of the C3D sonar is 192.168.0.40.

1.You need to configure the network card on the system that is running Isis to be in the same IP range, in the example we have chosen 192.168.0.39 (you must not use 192.168.0.40)

2.Open local area connections and select Properties for TCP/IP as shown below to the left.

3.Enter an address in the same range as the sonar as shown below to the right

SVS Network SettingsSVS Network Settings

SVS Network SettingsSVS Network Settings1. First , turn on the Odom Digibar by pressing the Power button (will light

red when powered)

2. On acquisition PC, open udp-serial-gui.exe

3. Select the Profile button, followed by Load button, to Load SVS.Conf configuration file

4. Navigate to the SVS.Conf file, select it, and press the Open button, to load for configuration of the udp-serial-gui software

5. Select the Connect button to connect the serial SV sensor for UDP output

6. Select the Serial Device button to verify correct com port (COM 5 for first USB serial device), baud rate (19200 for Odom Digibar) and protocol (8, None, 1, Off)

7. Select the Network button to verify the correct input (no choice) /output network IP addresses (192.168.0.39 and 192.168.0.40), UDP ports (4201, 4301), and hex-code line-feed (%OD) and carriage return (%OA) options are applied for output to the C3D

8. Select the Data button, to verify the SVS data are coming through and are correct (in air the digibar may read values below 1350m/s, however the C3D will not accept SV data below 1350m/s and the default value of 1500m/s will be displayed and used by C3D, until valid data are available - when the unit is submerged and reading sound velocity in water)

9. When done, minimize (DO NOT CLOSE) the udp-serial-gui program

10. Verify by opening the C3D Control Panel, under Utility tab select the Edit Server Configuration button, verify that the telemetry device SVS only /UDP/4301 line is enabled (meaning that corresponding line does not start with #) and verify the UDP port 4301 for receiving SV data from Serial to UDP software

9. If the declination angle needed change, select Update Realtime and verify the result in Triton Isis bathymetry display, then select the Save button, near Profile, to save to the default range.cfg profile

10. Adjust the Amplitude threshold (toward 1 to reduce multipath and poor accuracy data in far- and near-field ranges and water column, or toward 0 to increase swath width and allow lower amplitude echoes to be mapped), after each change, select Update Realtime and verify results in Triton Isis bathymetry display

C3D Sonar Settings C3D Sonar Settings (page 2)(page 2)1. Adjust the Unit Circle threshold (toward 0 to reduce mulitpath and poor

accuracy data in far- and near-field ranges and water column, or toward 1 to increase data resolution and allow greater variability in the angle of arrival from echoes to be mapped), after each change, select Update Realtime and verify results in Triton Isis bathymetry display, verify results in triton Isis Bathymetry display

2. Adjust the Bottom Tracking threshold (toward 1 to reduce multipath and poor accuracy data in far- and near-field ranges and water column, or toward 4 to increase data resolution and allow greater tolerance for distance between neighboring echoes to be mapped), after each change, select Update Realtime and verify results in Triton Isis bathymetry display

3. Select the Update Realtime button and verify the result in Triton Isis bathymetry display, then select the Save button to save to the default range.cfg profile

4. Edit the Default Profile name to generate a new profile and save the new threshold settings to the custom profile, after changing the name from default to a name of choice, select the Save button to save the current settings

5. Select drop-down triangle at right of the profile name and change back to default

6. Select the Save button, to save the current settings to the default profile

7. <<Note: If C3D range is changed, repeat steps B.24-35>>

Once the hardware is configured and the data is coming into the acquisition PC, Isis needs to be setup to receive all the different data streams. For this example, the following data streams need to be configured:

1. C3D data – Ethernet port

2. Motion data (roll, pitch, heave, heading) – UDP

3. Epoch Time - UDP

4. Altimeter – RS232

5. GPS – RS232

6. SVS – UDP

C3D System Setup QC C3D System Setup QC (Page 1)(Page 1)Once everything is setup, it is always good practice to verify the data is coming into Isis as expected. Here are a few options:

•Be sure all sensors are connected and powered on

•Be sure the C3D Control Panel is open, the Server.exe and Timeserver.exe programs are running

•Be sure the udp-serial-gui program is running and SVS data are visible

•Open Triton Isis and click on the ‘Record’ button (red circle in the upper left corner of the program) to start the Benthos C3D Controller server application

•In the Benthos C3D Controller “Connected” should be displayed in the upper left, followed by a green circle and a blue flashing circle, and the dialogue area should show MSG_COMMAND Sent: ‘Send Next Ping’ Succeeded, repeating, indicating the C3D is responding to commands from Triton Isis

C3D System Setup QC C3D System Setup QC (Page 2)(Page 2)

• The Voltage window should show a transmit peak centered along the x-axis (if both Channels 1 and 2, port/starboard, are enabled, if not, right-click on the display and enable Chan 1), indicating that the C3D transducers are pinging and receiving data

• Perform rub test, by setting range equal to 200m and gains about 20, 0.02, and 20 and rubbing the port transducer followed by the starboard transducer and confirming dark streaks on the Vertical Waterfall, with the port (channel 1) streak below the starboard (channel2) streak, confirming the C3D transducers are connected correctly

• The Vertical Waterfall window should show SV= (some real value, not 1500.0), as supplied from the Odom Digibar SVS, given the value supplied is not below 1350 or above 1650 m/s

• Verify that sensor data is being read properly by Triton Isis, select the Window menu, then Status and Control, and Sensors to open the ‘Sensor Display’ window

C3D System Setup QC C3D System Setup QC (Page 3)(Page 3)

• The Isis Parameter Display should show:

a. Lat, Long, Speed, and Heading, according to data received from GPS

b. Gyro, Pitch, and Roll, according to data received from CDL MiniRLG

c. Alt, according to Tritech altimeter (if values are bad, altimeter outputs 50.00m)

• Confirm Date and Time are set to UTC and that the PC time matches that of the GPS, to verify in Triton Isis, select the Window menu, then Status and Control, and Clock Times to display the Current Clock Values window and confirm all times are within 1-2 seconds, as displayed.

Note, the C3D DSP Linux-based CPU will provide the time source for all CDL MiniRLG2 and C3D data, whereas navigation data will be referenced to GPS source or PC, as selected in Triton Isis
