Networking Lowrance units with NMEA2000 (Lowrancenet) Below are a couple 
diagrams of a Lowrance NMEA 2000 Network. I found the diagrams online and 
modified them to help you during installation. These include wiring of the power 
cable and a typical red network bus. This power cable diagram does 
not apply to HDS units it is meant for the LCX/LMS units please see your manual 
for proper NMEA2000 powering options for the HDS units. <A

boats come pre-rigged withe NMEA2000 network backbone from the boat manufacturer 
and may use a Power Node to supply power the network. This Power Node is hooked 
directly into a Tee in the network bus. If your boat has one of these on the 
network DO NOT power the NMEA power wires from either graph. It is already done. 
Powering it twice will cause damage to the Module, graph and any sensors. I 
could not find an online picture of the red power node, but the concept is the 
same. <A href="http://www.lureshop.co.kr/nzeo/data/pot/NMEA_PWR_CBL.jpg"

HDS Models would require a Power node to supply power to the Network Bus. This 
diagram below shows the network bus configured for networking 2 LMS or LCX units 
to one GPS module <A

HDS Models with NMEA2000 The Diagram below shows adding an external antenna, 
which is optional. If you are not hooking up an external antenna get rid of the 
extra Tee in the diagram. Please note if you are only interested in waypoint 
sharing all you need to do is connect the two HDS units with an Ethernet cable. 
No NMEA Network is required unless you are using network sensors like 
temperature, fuel, interface cables or an external gps module. The NMEA 
Network is totally expandable, just remove the terminator, add a Tee to plug in 
your new sensor and replace the terminator back on the new end. It's that 
easy! HDS units Networked * if you are still using an older LMS or LCX 
unit which is networked to an HDS unit it can still power the nmea network 
through its power cable. (HDS units can not do this) If you are switching to all 
HDS units you have to buy the NMEA Power node to power the network, shown in the 
diagram below. <A

></A> Parts 
needed to network two HDS Models: 1) NMEA Starter kit: N2K-EXP-RD-2 
(#124-69) kit includes: Includes 2 terminating resistors (TR-120M-RD, 
TR-120F-RD), two T-connectors (N2K-T-RD), one 2 ft extension cable 
(N2KEXT-2RD), and one 15 ft extension cable (N2KEXT-15RD), and a power node 
(N2K-PWR-RD). $51.99* 1) T connector, N2K-T-RD #119-79 $14.99* 
 ------------------------------------------------------------------------------------------ 60 
ohm Termintors and 120 ohm Terminators When to use a 60 ohm and when using 
two 120 ohm is required. I'll try to keep this short as possible, Lowrance 
units work on 60 ohms. The network terminator keeps the data flowing from 
different devices (gps module, temp/fuel sensors) in the correct direction and 
in a mannor that the unit can process. Okay we already know Lowrance units 
require 60 ohms. But two 120 ohm terminators in parallel equals 60 ohms. When 
connecting one unit and a gps module a 60 ohm terminator would work fine. But IF 
you expand this nmea network to include another unit or more it is required to 
use 2- 120ohm terminators, one on each end of the network. 
 ------------------------------------------------------------------------------------------- Waypoint 
sharing between units, clarification Waypoint sharing with LMS or LCX 
units: A NMEA 2000 network must be used to share waypoints between these units. 
Ethernet will not allow waypoint sharing, only HDS models can use Ethernet for 
waypoints. Waypoint sharing with these older models will not automatically 
transfer all of your waypoints from one unit to another unit. This must be done 
manually with a card. Waypoint sharing works "one at a time" as you first create 
the waypoint, it will then transfer that data to the other unit. Both units must 
be powered on for it to transfer. Wapoint sharing with HDS models: 
Ethernet will share waypoints as well as NMEA 2000. But with the Ethernet you 
will have advanced or enhanced waypoint sharing and editing which means the two 
units will auto synch with each other once connected and turned on. No manual 
tranfers needed. This is a great feature. You can edit a waypoint on one unit 
and the changes are made to the other(s) automatically once they are turned on. 
Other units do not have to be on during waypoint creation. Once connected it 
will synchronize the other 
units. ------------------------------------------------------------------------------------
