nmea output from Raymarine Graphic

[j34035]

I am trying to get the nmea outputs from my raymarine graphic instrument. It has depth, speed, autopilot and wind connected to it. I can see all the values from all sensors displayed on the graphic repeater. According to the documentation it should output Depth (DBT), Heading, deviation, and variation (HDG), Magnetic Heading (HDM), Water Temperature (MTW), Wind Speed and Angle (MWV), and Water Speed and Heading (VHW) through the nmea output port. I have enabled the nmea output in the calibration mode and I can connect to the nmea output of the instrument to my serial port and see the sentences being transmitted. Following is a capture:

$IIMWV,114.5,R,2.9,N,A*37
$IIMTW,21.7,C*17
$IIDBT,10.5,f,3.2,M,1.8,F*2D
$IIMWV,109.5,R,2.7,N,A*35
$IIMTW,21.7,C*17
$IIDBT,10.4,f,3.2,M,1.7,F*23
$IIMWV,106.0,R,2.5,N,A*3D
$IIMTW,21.7,C*17
$IIDBT,10.4,f,3.2,M,1.7,F*23


How can I get it to transmit the other values (HDG, HDM, and VHW)? BTW, the version is 2.04 and the documentation is from the vendor at purchase. Thanks for any help!!

It may depend on what you have connected to it...

It can't output information it doesn't have. For instance, the HDG, HDM may need to be supplied by a fluxgate compass or GPS. The Autopilot might supply HDG, HDM but will not do so unless it is on IIRC. VHW is probably also a compass related datum.

The instrument displays all the data that is described in the sentences. I have the fluxgate compass on the autohelm and the magnetic heading is displayed on the graphic. Same with speed. It is a multi instrument that has depth and speed and I can see them both on the graphic, but only depth is being transmitted. I do not expect the graphic to transmit data it does not have, and I have confirmed that all data is present in display pages, and is active. hmmmmmmmmmmm!

Just curious, what version of the software is on your Graphic display. The latest, according to the Raymarine site is 1.03.

BTW, I didn't see anywhere in the ST60 Graphic user's guide a list of the NMEA data that is output... I'm curious as to where you found the list you're using.

I just confirmed the version is 2.04. I will send a query to Ray and see if they can give me a response. Thanks for the followup!!

Is the 2.04 the NMEA version or the firmware version on the hardware?

[j34035]

Hardware on the Grapic instrument.

Apparantly there was an "upgrade" to ST60 Plus. Mine must be the older one. I cannot find an output table for what is available for nmea. Any ideas out there?

I'm sort of with SD here - my first reaction was that the graphic basically just displays data supplied by other devices - has it got the ability to generate and put out data? I don't think it does.

Generally, to go from Seatalk, which is everything you've got, to NMEA, which is what you're trying to do, you need to use a Seatalk-to-NMEA bridge. AFAIK, none of the NMEA out ports on any of the other equipment will relay all the information... just bits and pieces of it.
