Re: [gpsd-users] Ideas for Kenwood D700 Radio Support

Alexander,

Well, I was looking at the gpspipe command, which it seems would be  
able to do the job of sending NMEA strings to a serial port. Whilst  
the gpspipe is capable of output at 4800 Baud (and so too can the D700  
accept 4800 Baud data), I'd like to add a 9600 Baud option to gpspipe.

Moreover, I am curious what the D700 would do when it receives things  
like the initial blast of JSON data that gpspipe outputs when it  
initially dumps "-r data". Granted, I could simply add a switch to  
gpspipe to turn that happening off, but, what about other NMEA strings  
or Zodiac strings that get sent to the D700? What does the D700 do  
with them? Just toss them?

The waypoint upload, that is how the D700 sends station information to  
be plotted to something like the AVMAP?

Seems this might be a really good use for a Pi! The Pi could be used  
to run gpsd to get EarthMate data via a USB/Serial dongle and then use  
the serial port on the Pi to output/input to the D700 via a 2.5mm  
cable. Or just add another USB/Serial dongle to it and keep the  
internal serial port for console use.

I am just curious, since I think xastir can accept input from the  
D700, so it might be worth having that pin on my cable (the TX pin  
from the D700 that sends the waypoint data on it).


V/R and 73,
