charplotter antenna gps

[MI3GTO]

Folks in general if I have a chart plotter that uses a external antenna, if I feed any NMEA signal to it should it detect the data? I think I have a broken antenna and would like to test the plotter unit by using another working gps with nmea out. likewise if i connect the suspect antenna to a 12v supply and the nmea wires o a serial on a laptop running nmea monitor software should i see the data? i ask as i am not sure the antenna uses nmea???

Can you post the plotter and GPS antenna make/model numbers?

Yep guess that would help :-)

I will tomorrow as the kit is not here at home. I have found that there was no 12vdc out from the plotter to the antenna. I fed a 12vdc on the cable from an external battery but still no recognition of the antenna by the plotter. So the thinking is along the lines of testing the antenna first to see if it is sending data out. If the antenna is working that leaves the plotter.

I will post make and model tomorrow. Are there service diagrams available for marine kit?

Is it NMEA 2000, if so a seperate 12v feed is required to the backbone!!!

Lowrance does not need external 12V if all you're using is the GPS module. Anything else, and yes, you're right.

Don't know if that's true with other manufacturers.

Sorry But beg to differ, we have installed numerous Lowrance networks

Taken from the Lowrance website
" The NMEA 2000® network 12 Volt Power Source connects to the boat's 12-volt supply to power devices like the EP-10 Fuel Flow Sensor, LMF-400 Multi-Function Gauge, and LGC-2000 GPS Module."

Stand corrected. I recalled what I said from setting up my old unit; incorrectly, apparently, from rereading the manual.

Sorry for the confusion.
