[pmv-2007]

is it possible to interface a garmin gmr18 radar, that usualy talks to a garmin marine network, to an rs232 port. and does it output sentences like:

RSD - RADAR System Data
14
1 2 3 4 5 6 7 8 9 10 11 12 13|
| | | | | | | | | | | | | |
$--RSD,x.x,x.x,x.x,x.x,x.x,x.x,x.x,x.x,x.x,x.x,x.x,a, a*hh<CR><LF>
Field Number:
9) Cursor Range From Own Ship
10) Cursor Bearing Degrees Clockwise From Zero
11) Range Scale
