Change address - aAb!
The factory setting for the address of the wind speed is "
0
", for the wind direction "
1
".
If there are several sensors connected to one bus, the sensor address can be changed with the command
aAb!
.
The address is always a single ASCII character. Standard for addresses are the ASCII characters "
0"
to "
9
"
(decimal 48 to 57). If there are more than 10 sensors connected to one bus, using the characters "
A
" to "
Z
"
(decimal 65 to 90) and "
a
" to "
z
" (decimal 97 to 122) is allowed. The sensor answers with its new address and
<CR><LF>
.
After the address is changed, one should not send further commands to the sensor for a period of one second
(see also "SDI-12 Standard, Version 1.4, 2017").
