Networking two HDS 7 Touch

I have bought two HDS 7 Touch units. One is the bundle with 83/200 and LSS-2 transducer. The other one comes without a transducer. I also bought a Point 1 antenna. Both units will be mounted side by side. I know that I need a NMEA system. I am not sure how to hook these up together. I would like to run one unit with sidescan and 2D and GPS & downscan on the other. Could someone tell me if I have everything listed below that I need?

Have:
2 HDS 7 Touch units
1 83/200 Transducer
1 LSS 2 Transducer
1 Point 1 Antenna

Check list.
Power to both units.
I need one T and Terminator to power the NMEA system.
I need one T for the Point 1 antenna.
I need one T for the first 7 Touch.
I need one T and Terminator for the other 7 Touch.
I need one Ethernet cable.
If I hook the LSS-2 and 83/200 transducers to one unit will it read on both units?
Do I need more cables to get from NMEA Ts to the Point 1 and both units?
I am trying to get everything before my other unit comes in.
Thanks

Everything on the nmea network will need a cable and T, including the power node.

"If I hook the LSS-2 and 83/200 transducers to one unit will it read on both units?

Yes, through Ethernet. You will need to go into the menu's and set up the source.
