Page 17: Identifying Seahub Serial Ports
Having completed the driver installation procedure, the PC should have installed six “Virtual Communication Ports” (VCPs) that map to Windows serial communication (COM) ports. These ports will be removed when the SeaHub is disconnected or powered down, and reappear next time the SeaHub is connected. - Page 18 There should be six entries titled “USB Serial Port (COMx)” in this list, each representing a serial port within the SeaHub module. In the example shown here, these are numbered from 9 to 14. Make a note of these numbers, as the Seanet software will need to be configured with them.
