ROSA - MES12 Data Message

The MES12 Data Message 12 is used in the ROSA Surface

Analyzer for Roads and Runways system. You can use this data

message when WMT700 is connected to the Vaisala ROSA

system.

This message contains sensor identifications (sids), corresponding

data items, and the synchronization characters SOH, STX, and

ETX. The lines are ended by CR and LF characters.

For more information, see Chapter 5, Operation, section Data

Messages, in the Surface Analyzer for Roads and Runways

ROSA, DM32 Version User's Guide (M210242EN).

Missing Readings

If WMT700 is not able to measure the wind, it indicates a missing

reading in the output. Most common reasons for measurement

problems are ice, birds, or other foreign objects on the line of

measurement.

When the WMT700 profile is used, WMT700 indicates missing

readings by showing 999 in the data messages.

Example:

When the WMT700 Data Message 22 is polled, missing readings

are indicated with the following response:

$999.00,999.00<cr><lf>
