replaced 2 older ray screens with 2 new e125
there was an existing ray 125 gps
and some seatalk
instruments so put in a seatalk
to seatalk hs converter
both screens have gps
from external gps, instruments working. all seatalk 1 / seatalk hs / seatalk ng working fine.
however the problem I have is with the nmea
out feeding 2 icom
vhfs. (502 and 604)
after spending hours of screwing around. (changing which screen
was master and which one was outputting nmea
, only one vhf
at a time, turning off all uneeded output strings etc) I figured out the vhf
would pick up position as the screen
was booting up. but lose it 10 secs later almost like it was only outputting nmea during start up.
so I hooked my laptop
up. and I was getting constant strings. but I was getting "ecgll" and "ecgga" strings which I've never seen before. not the normal gp ones.
so I pulled the seatalk ng cable out. screen changed to internal antenna
. and then the nmea output charged to normal gp strings. and vhf kept pos.
what's up with this? what is the ec strings? and why is the chart plotter putting out nmea strings the vhf can't understand?
is the converter doing somewhere weird with the gps data, or is it the plotter? the plotter was working fine with the ext antenna
I'll probably just leave the gps antenna off. the e125 internal ones are probably better anyways...
