WMT700 data message 25 reports wind
measurement, sonic temperature, and status data. The checksum is included in the message.
WMT700 calculates the checksum by applying 8-bit XOR for all bytes between checksum
calculation start point and end point. The result is printed as a 2-digit hexadecimal value.
The message is in the following format:
\ss$\ws,\wd,\wp,\wm,\Ts,\er,\se\sp\cr\lf
| Name |
Description |
| \ss |
Checksum calculation start point, not shown in the message |
| $ |
