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.
┌_$02.66,98.21,02.66,02.60,95.68,99.53,99.34_D8<CR><LF>
The non-printable characters are shown above as ┌ ┘and <CR><LF>.

Status Flags
The following list describes the status flags included in the data message when the status
code item \er has been added to the message. Each bit corresponds to a
specific status.
Status flags are coded in decimal number format. To extract each bit from the status code,
the decimal number must be converted to binary format.
Table 43 Status
Bit Description
0 Temperature sensor 1 failure
1 Temperature sensor 2 failure
2 Temperature sensor 3 failure
3 Heater failure. Incorrect heater element resistance
4 Too high (Vh > 40 V or Vi > 40 V) supply voltage
5 Too low (Vh < 20 V or Vi < 10 V) supply voltage
