8. From your computer’s Control Panel, • Open the Network Connections • Select your LAN Connection • Highlight the “Internet Protocol (TCP/IP)” • Click on the “Properties” button • Enter the IP Address and Subnet Mask below

10. Settings • Network Settings • Connect ALL R2Sonic Cables and “Power ON” the R2Sonic SIM Box • Click on the “Discover” button • If the Network IP Address is set correctly on your computer, the Sonic Controller will automatically find the R2Sonic Sonar and establish communication with it

11. Settings • Sensor Settings • Enable and Configure : • GPS Input settings • Motion (MRU/IMU) Input • Settings for Roll Stabilization • SVP (Sound Velocity Probe) • Input Settings • Match the ‘jumper’ setting • inside your 1PPS Box to • to the correct Edge (Rising • or Falling)

12. 1 PPS Box Jumper Settings This Special Setup allows for the PPS Pulse to come in on Pin 9 from the GPS Serial connection and then Output thru the BNC connection Rising Edge Falling Edge

13. Settings • Ocean Settings • In waters with a large sediment load, the suspended particles will scatter the sound wave, thus leading • to transmission loss. In the scattering process, there is also a degree of energy that it is reflected • (backscatter); this can be a cause for ‘noise’ in the sonar data. Again, the surveyor should be aware of • this condition and, if need be, change the operating parameters of the Sonic 2024/2022. • It is generally a matter of increasing transmit power or pulse length to get more total power into the • water. In some circumstances, increasing the Absorption value will allow the system to rapidly increase • gain to capture the reflected energy that has been dissipated by seafloor absorption or scattering in the • water column. • As noted above many of the effects of absorption, scattering, and bottom absorption are frequency • dependent. With the Sonic 2024/2022, the operator can adjust the sonar frequency to optimise the • system for the survey conditions. This will take some trial and error; however, lower frequencies • tend to do best in areas of absorbent bottom and high sediment load (scatter).

Controller -- Main Display To change a Control Setting value, position the mouse cursor over the button Use the LEFT mouse button to Decreasethe value And the RIGHTmouse button to Increasethe value. System Information: • W: Wedge sector (opening angle) • T: Sector Tilt angle • G: Minimum and maximum depth gates • f: Operating frequency • c: Sound velocity at the sonar head • PR: Ping rate • D: Nadir depth

23. Control Value Ranges Range: 0 – 500 m Power: 0 – 221 dB Pulse Length: 15 – 500μsec Gain: 1 – 45 Depth Gate Min should be set just above the most Minimum depth in the swath Depth Gate Max should be set just below the most Maximum depth in the swath
