I picked up a used Lowrance lcx 27. I have a cable that connects fine to the puck but it ends in a male connector which won’t connect to the network slot on the unit which is also male. I am having zero luck finding a female to female network connector. Anyone have one? or know where I can get one? The color is maroon on the cable ends.
Have to get a “t” and a 60ohm terminator, at least that how mine is.
U lucked out already had a pic hosted…. course it’s not a 27, but same idea.
Man you are speedy. Can the T hook direct to the back of the unit?
Nope or I would’ve done it.

You cannot connect a T to the back of the unit.
Here are some setup examples >>>> Network Examples
The easiest way to set up a one unit one puck network is
the first example. I’ll try and get you a part #.
If you have an LGC 3000 GPS antenna, Lowrance insists that for long life of the antenna that it is mounted at least 3 feet away from the head unit. The interference from the head unit will burn out the filter in the antenna and it will fail. This is why the short cable on the antenna cannot be conected directly to the head unit.
The antenna will plug into the top of the tee, a 60 ohm terminator will be in one end of the tee and the long cable connects the tee to the head unit, at least 3 feet away from the head unit, on the opposing end of the tee.
If you use one antenna for two head units then you will need to have three tees, one for each head unit and one for the antenna to plug into. For this installation you will need two 120 ohm terminators because you have multiple units. The upright connection on each tee will be connected to each device with a short cable and the horizonal connections, those opposed to each other, will be used for terminators at each end and cables connecting the tees together in between each of the 3 tees.

Is this the way you would set up his network Ken?
You make it seem as it’s the only option for a one
unit network. 
Now I am confused. It is a 3000 puck. It is 3 feet away from the unit on my boat. I have a cable that attaches to the unit. The picture in figure one DD put up sure looks like the setup I need but that references 2000 not 3000. Can I use the cable with the 120 ohm terminator built in or should I go with a T with a 60 terminator on the short puck cable connecting to the extension cable?

It references NMEA 2000 not LGC-2000. They don’t label the
GPS module in the diagrams.
You will need a T and a 60 ohm terminator OR a cable with
the built in 120 ohm terminators (one one each end) to
get your setup working.
If your plan to add a unit later, HDS or LCX, I would
set it up with two T’s, two 120 ohm terminators, and
an extension cable for the puck and an extension cable
to the 27C. When you expand to add a unit you will just
need to purchase one T and another extension cable.
Hope this helps!!

Thanks for that info Ken, my puck sat about 18″ from the unit, at least it was a lot easier to relocate than changing out the console transducer..:)
