linking lowrance units

can you link a 37c and a 27c so that you can use just one ducer? I thought that there was a way but I am not sure now

Yes, with the orange/yellow ethernet cable.

Good luck getting the cable… everyone appears to be backordered.

Try Thorne Brothers they will ship it directly to you

Thanks Guy’s

Actually that is one place I haven’t checked. I will check with them this afternoon but even Wade from Jolly Ann is backordered so I am not going to hold my breath.

Thorne Bros has them in stock!!

Glad I could help. They normally have alot of that stuff on hand or can get it in a short amount of time.

I have connected two 520C units with a 25′ ethernet cable so that both units can read the universal sonar transducer in the Minn Kota V2 at the bow. Both units received software updates today and they are also networked with a 25C via NMEA network which is working fine. However, the objective has not been met.

When the 520c units are operated individually(no ethernet connection)they each display depth and temperature. When the transducer is disconnected from the 520c at the stern and the ethernet connection is made between the two 520c units, the bow unit reads depth but looses temperature and their appears to be no signal to the stern.

So what am I missing or what have I done wrong? Thanks for any and all suggestions or pearls of wisdom?

Why are you disconnecting the stern transducer?
The ethernet will allow you to select which transducer you
want the units to read. You can display the transducer
info from the rear on both or from the bow on both.

Dan. Thanks for the reply. I’ll connect the stern and try again. At which screen/page would the tranducer selection be made?

There is no Navico Expansion Port in line, just the ethernet cable connecting the two units. Is the Expansion port needed to make this work?

JWF

You shouldn’t need the expansion port. I can’t remember where in the menu the transducer selection is as its been a couple years since I switched to HDS and the menus are totally different. You may not get temperature off your bow transducer. My last one didn’t provide temp but my current one does.

From the Sonar page I think you hit;

Menu

Sonar Features

Sonar Source

Then select which source you’d like.

Dan: So this afternoon I walked around the boat twice to the right, once to the left, connected the stern transducer as you suggested, powered up the units and………….they worked as hoped without even having to make any selections on the menu. Thanks for the guidance.
