Icom Radio NMEA 0183 Interface
Posted: Wed Mar 30, 2016 6:45 pm
One of my VHF radios is a Icom IC M-504. Here is the manual: Icom IC M-504 manual
Last season I had this set as my DSC distress radio. My Northstar 952 was interfaced with the Icom to provide position and time data.
The radio worked fine and always displayed the Northstar's position and time on the main screen.
This season I replaced the Northstar with a a second HDS Gen3. This was the only change to the the VHF and Chart plotter set-up. Now, I cannot get the radio to display position data. I have tried outputs from both HDS units and both ports. I even went as far as to hook up the Northstar, which still has the NMEA 0183 connections on the data cable from when it was removed, the Northstar' took a while to [get a position fix], but even after an hour I still have no position data.
Is there a way to test data output on a NMEA interface?
Is there a way to check the VHF to see if there is any data coming in to the radio?
Stumped.
