Example
In this example the data message 2 is set to include the following items:
• SOH
• Checksum calculation start point
• Wind speed, average
• Wind direction, average
• Wind gust speed
• Wind lull speed
• Wind direction minimum
• Wind direction maximum
• Wind direction during the peak speed (wp) occurred
• Checksum calculation end point
• EOT
• Print checksum
• CR
• LF
S msg2,\01\ss$\ws,\wd,\gu,\lu,\dm,\dx,\w1\se\04\sp\cr\lf
WMT700 sends the following message that starts with the SOH character which is
excluded from the checksum. The checksum ends before the EOT character. The
checksum (in this case, D8) is printed after the EOT character.
