Command Responses
Command responses are only issued when in interactive mode.
Configuration Commands
On receipt of a configuration command, the anemometer will respond with a validation
message if the command was successfully actioned, or an appropriate error message if
it was not. If a configuration command is entered with no data parameter, the current
data value is returned.
Interrogation Commands
On receipt of an interrogation command, the anemometer responds with the requested
information if the command was successfully completed, or an appropriate error
message if it was not.
Invalid Combinations of Commands
It is possible through the setting of various parameters to request a configuration where the required
output bit rate exceeds the configured baud rate.
If an issued configuration command requests a parameter change that would cause the above
situation, an appropriate error message is generated.
COMMANDS
The command descriptions use a modified form of the BNF format:-
|
Option, one option from a list separated by the vertical bar must be included in
the command.
() Parenthesis, used to make the possible combinations unambiguous.
[] Option, the symbols within the square braces are optional.
n{}m Repeat, the symbols inside the braces can be repeated n to m times. If n is not
included then 0 is implied, if m is not present then infinity is implied.
<> Non literal symbol, this represents other non literal and literal symbols. A
further definition is required to define this non literal symbol.

WINDREP
Syntax: WINDREP ( UVW | POLAR ) ( CAL | UNCAL ) | AXIS
