Set the value 0xFF to the Application Object1 with Instance ID 0x01 and Attribute
ID 0x02. After sending the
“Set Attribute Single”, the slave device will response
0x90 to mean that the setting is OK. Then the DO4, DO5, DO6, and DO7 will be
turned ON and others are turned OFF.
Via changing the Attribute ID of the Application Object, user can set other
parameters of this device.
