is added to the response data strings before <cr><lf>.

where

a = Device address

C = Start concurrent measurement command

x = The desired measurement

1 = Wind

2 = Temperature, humidity and pressure

message in which the user can request data from

several sensors with just one command. See the

examples below.

where

a = Device address

ttt = The measurement completing time in seconds

nn = The number of the measured parameters available

(maximum number is 20)

<cr><lf> = Response terminator

For changing the message parameters, units and other settings, see

Chapter 8, Sensor and Data Message Settings, on page 107.
