The following commands are available on the RS-485 communications link to the PICWND front end. This is a 9600 baud link and the PICWND is NOT addressable. This is NOT like other front ends.
Note: commands sent are indicated in BOLD, responses in normal text. <crlf> represents ASCII carriage return and line feed. The space after the BOLD command in each example is for clarity - it is NOT actually transmitted.
Command Description
C Complete data return
- one return takes 5 seconds
- a single line response consisting of wind speed HEX counts for
5 second interval, 5 readings of vane HEX degrees * 10 at 1 second
intervals, a compass reading in degrees 0 - 359.9, a pitch reading
in degrees +/- 50.0, and a roll reading in degrees. +/- 50.0.
- e.g. C 0125 04B5 04B5 04C2 04C7 04D1 35.6 P0.2 R-1.2<crlf>
H Help
- a single line response indicating the available commands.
- e.g. H CMD: C,H,T[C,T,S,V],V<crlf>
T Test commands
- continuous output until character received
C - compass direction
- e.g. TC 345.2

345.1
.
T - tilt X and Y (pitch and roll)
- e.g. TT P2.1R-2.7
P1.9R-2.6
.
S - speed in HEX counts at 1 second intervals
- e.g. TS 0125
0125

.
NOTE: any character received will abort continuous output.
