NMEA Needed for 3D Transducer?

[AWC360]

Found a good deal on a New in Box StructureScan 3D Transducer and Module. I currently have a HDS 7 Live with 3-1 Active Imaging. With the parts that come with the 3D, do I need to setup a NMEA now or can I only use what I will have?

Thanks in advance.

Ethernet is what you need for SS3D

Great. Now is there much amp draw to the module?
