The

button starts communication with the Gemini head. When the
software is started the head will not be running and the
Online
button will
be grey.
Clicking the
Online
button will start the Gemini head; the button and the sonar
cone image next to it will change to green. Clicking the button a second time
will stop communication with the head, and the button and sonar cone will
return to grey.
If the
Online
button is pressed while no heads are visible to the Gemini software, the
following message will be displayed.
Clicking OK will acknowledge the message, and the software will not go online.
If the
Sonar ID
entered in the Sonar box of the configuration settings is not one of the heads
visible to the Gemini software when the Online button is pressed, the software will present
one of two messages.
If only one head is visible, the software will offer the chance to start imaging from that head.
Clicking
Yes
will cause the software to select the head which is visible to it. Clicking
No
will
acknowledge the message, and the software will not change the selected head and will not
go online.
