The addressing format of the attribute values differ from the normal mode. A con-
nection path attribute that specifies class 4, instance 5, and attribute ID 3 is illus-
trated below:
Class #4 Instance #5 Attribute #3
20 04 24 05 30 03
The instance defines the assembly you want to use. This format has to be used by
the master in the request and is used by the slave in the response.
Set the input assembly 04 for a poll connection (addresses as specified
above)
