That is all well and good, but according to the documentation in
Raymarines commisioning guide for the graphic instrument:
What NMEA data is supported?
Sea Talk to NMEA 0183
Data from Sea Talk is transmitted to the NMEA OUT connector every 2 seconds. The supported NMEA output data is detailed in the following table:
Depth: DBT
Heading, deviation and variation: HDG
Magnetic Heading: HDM
Water Temperature: MTW
Wind Speed and angle: MWV
Water Speed and heading: VHW
This is transcribed straight out of the
Raymarine book document number 81228-1 dated January 2004.
Again, I can recieve the following data:
$IIDBT,10.5,f,3.2,M,1.8,F*2D
$IIMWV,131.5,R,2.3,N,A*3A
$IIMTW,21.7,C*17
This is a capture from the instrument to my laptop serial input using Hyper terminal. Why can I not get the other datas? I am posting this query to Ray in hopes they can settle this for me one way or another. I appreciate the input from you guys, but if the vendor says it will work, then doggone it, it should work. I will post whatever reply Ray gives me.
