I just read the manual of my autopilot. Why, I did not do it sooner!
Obviously, you're right. Unable to send a road or even just waypoint.
So you're right, leave the item as you did.
But I have another question.
In the manual of the autopilot I found the list of NMEA
sentences he uses.
Suppose a boat very well equipped electronic instruments (This is not the case of mine, but that's another story). Using a connection to a port input and / or output, will my OpenCPN to provide autopilot every sentence he may need? And vice versa, will my OpenCPN NMEA
sentences using the autopilot issue.
Below is a list of NMEA sentences. I read this list on the SIMRAD
manual (TP10/TP22/TP32) page 26:
6.3 NMEA sentences received
The NMEA 0183
information required for full functionality of
the TP22 and TP32 whilst in Nav mode is as follows:
– Cross Track Error
– Bearing to destination
– Arrival at waypoint indication
– Magnetic variation
– Boat speed
This information is extracted from the following NMEA 0183
APA Cross Track Error, bearing to/arrival at waypoint
APB Cross Track Error, bearing to/arrival at waypoint
RMA Speed & course over ground & magnetic variation
RMB Cross track error, bearing to/arrival at waypoint (T)
RMC Speed & course over ground & magnetic variation
BWR Bearing to/arrival at waypoint (rhumb line)
BWC Bearing to/arrival at waypoint (great circle)
VHW Boat Speed
XTE Cross Track Error
Note The Cross Track Error (XTE) information has a maximum
value of 1.2 Nautical Miles. If the XTE exceeds this while using
Nav mode, the Tillerpilot will sound an alarm
, exit Nav mode
and return to Compass
The Tillerpilot also extracts the apparent wind
angle from the
following NMEA 0183 sentences:
VWR Apparent Wind
Speed & Angle
MWV Apparent Wind Speed & Angle
Thank you in advance for your answer about this long post. I'll obviously need an answer for me to write with less de'erreur possible, a web page on the website that I provide for OpenCPN. Thank you in advance for your detailed response.
Best regards Gilletarom.
