I picked up a 2nd lowrance unit for my boat and wanted to network them together in order to share sonar and waypoints. Before I start pulling cables and drilling holes, I wanted to know if the setup I have pictured below will work.

Thanks for the help.

In your diagram you have the GPS on the side of the tee. The opposing ends of a tee are to be connected to each other or extension cables between tees. Devices like head units, GPS antenna, external temp. sensors are to be connected into the top of the tee. You will need one male and one female terminator. One terminator goes on each end of the backbone. See the sample network below to see a visual of what I'm talking about.

I'm also working on setting up a network - I have only 1 60 ohm resistor and need one more. I have a 'blue' network but may eventually add a newer (HDS-type) device to it. Should I be using 60 or 120 resistors? Does it matter? Is 60 for one head unit and 120 for two units?

If you have more than one device connected to a NMEA network, then you will need to go to 120 OHM terminators. These can be hard to find for a blue network. Look on leiextras.com and check out the clearance items. If you don't find any, you may have to become current with a red/black network. This is the network that the HDS connects to normally.
