Figure 51: Set Commands
When a valid message is recognised by the sensor, the sensor will carry out the command contained in the
message. To verify that the command has been successfully carried out, an associated QUERY command can
be sent after most SET commands (see Section 6.1.2 for the list of parameters which may be queried).
