Data polling:
The table below shows the procedure of data polling (bus address 100). To get the specific value the
master first has to send a request: OP100\r. The sensor confirms this with OK\r and responds to the
following GN\r request with the measurement value.
Master

\r
OK

GN

Here, the OP bus address
100
and then the raw measurement value of
009000
is collected through the
command
GN
.
(Example:
bus address
100
→
FRT 3;
measurement channel
2 “temperature”
; value: 009000)
Change bus address;
To change the
bus address
for a specific measurement
channel you have to use the command „SAD”.
For e
xample the command „SAD2 100
\
r“
changes the
bus address
1 of the
measurement channel
2
“
temperature
”
to the
bus address
200.
