All R2Sonic multibeam echosounders communicate via Ethernet, so your network settings must be configured correctly.
Navigate to default network card settings.
Go to your network properties and select IP Version 4 (TCP/IPv4), then Properties.
Ensure all firewalls are off and virus checkers are disabled.
In Sonic Control, go to Settings -> Network settings and select the Discover button.
When configured correctly on your network, the R2Sonic equipment will respond with its serial number.
In a single head installation, the R2Sonic serial number will populate automatically and correspond to the Head or the SIM and their default IP addresses and base UDP ports.
Select Apply, and Sonic Control will send the correct IP address to the Head and the SIM. You should now see dots in the display.
The serial numbers and IP address are now stored in the CurrentSettings.ini file and will be applied automatically when the system is turned on.
