Description
aAb!
b<cr><lf>
Change the address of the sensor
where a is the current (old) sensor address (“0
-
9”, “A
-
Z”), A is an upper
-case ASCII character denoting the
instruction for changing the address, b
is the new sensor address to be programmed (“0
-
9”, “A
-
Z”), and ! is the
standard character to execute the command. If the address change is successful, the datalogger will respond with
the new address and a <cr><lf>.
Send Identification Command: aI!
The send identification command responds with sensor vendor, model, and version data. Any measurement data
in the sensor's buffer is not disturbed:

The sensor serial number and other identifying values are
returned
where a is the sensor address (“0
-
9”, “A
-
Z”, “a
-
z”, “*”, “?”), 521 is the sensor model number, vvv is a three
character field specifying the sensor version number, and xx...xx is serial number.
Running Average Command
The running average command can be used to set or query the number of measurements that are averaged
together before returning a value from a M! or MC! command. For example, if a user sends the command
“0XAVG10!” to sensor with address 0, that sensor will average 10 mea
surements before sending the averaged
value to the logger. To turn off averaging, the user should send the command “
a
XAVG1” to the sensor. To query
the sensor to see how many measurements are being averaged, send the command “
a
XAVG!” and the sensor
will
return the number of measurements being averaged (see table below). The default for sensors is to have averaging
turned off.
