14.5 SDI-12 Commands
WindSonic Option 4 complies with SDI-12 Interface Standard V1.3
We advise that you download the full SDI-12 specification from www.sdi-12.org
All other commands not defined below respond with a ‘zero data values ready’ response.
All units of measurement are in metres per second. This cannot be re-scaled.
Wind Measurements are made at 1Hz.
The default operating mode is aXHPM!.
The default unit address is 0 (a or A = unit address).
The unit is set for fixed field operation.
Commands and Returns in High Power Mode (aXHPM!)
When in high power continuous mode, Wind data (Polar or Axis format) will be logged
internally at 1Hz such that a 1-minute rolling average and 1 minute maximum (with
associated direction) can be retrieved at any time.
1 minute averaged outputs are available using aR2!, aR3!, aR4! and AR5! Commands.
NOTE : When powering up the unit wait 9.5 seconds before sending a command.
