Vaisala WINDCAP WMT700 Series - Measurement Mode Commands; WMT700 Profile Commands

• WMT700 checks the status of the internal operational software at each reset by
verifying the CRC checksum of the software. The software check is not made
periodically; it is only made at each reset. If the checksum is incorrect, WMT700 does
not start up. If the checksum is correct, WMT700 continues by calculating the CRC
checksum of the parameter memory. In case the parameter memory is corrupted, the
sensor replies with the text Parameters crc error upon startup. In case the
parameter memory checksum is correct, WMT700 replies with the text ready as
shown in the example below.
>$WMT700 v<version number>
ready.
• To check the status of the wind sensor, include the status code item \er in the data
message. You need to convert the status code to a binary number to verify the status.
An error code does not indicate that the wind data is invalid.
• To check that the wind data is valid, include the \va item in the data message.
• To check other diagnostics-related data, include the required items in the data
message.
