Rudder Angle over Seatalk NG from Seatalk

[Bill Kneller]

How can I get the rudder angle which is NMEA 2000 PGN 127245 (NMEA 0183 RSA) so it appears on the Seatalk NG bus?

The system in configured as follows (link to my schematics on page 1 & 2).

- Raymarine S1G connected via Seatalk to E22158 Seatalk to Seatalk NG Converter
- Seatalk NG (NMEA 2000) has the following on the bus
-- e97 MFD
-- e125 MFD
-- B&G T41 Triton Display
-- Garmin GND10 (Interfaces with Nexus Instruments)
-- Actisense NGW-1-ISO (Interfaces with AIS/DSC/VHF Radio)
-- Actisense NGW-1-USB (Interfaces with PC)

I am able to see the rudder angle transmitted from the S1G over Seatalk, through the Seatalk NG converter on the e97 and e125 displays. I am able to see other data on almost everything everywhere. I am unable to pickup the rudder angle on either the T41 Triton display, or on the PC through the Actisense converter.

Using the Actisense NMEA Reader tool I am able to see what is on the NMEA 2000 (Seatalk NG) bus. PGN 127245 is not detected, so it appears that is why I don't see rudder angle on the B&G T41 Triton Display or the PC.

Does the converter transmit rudder angle on the NMEA 2000 bus using PGN 127245?

If not, how can I get this information?

It is obviously being transmitted in some format over Seatalk NG because both the e97 and e125 displays show rudder angle.
