The Assembly Instance Selector Object is a vendor-specific
object available in the OPTCQ option board and the OPTE9.
It allows the user to get and set the input and output
instances used.
The OPTE9 option board will automatically change the
current assembly instances by what is requested in the
connection opening. This means that it is not mandatory to
pre-set assembly instances.
