Interoperability Allows...
 Devices from different manufacturers are able
to interact with each other without Host
interaction
– Control in the field works seamlessly
– Devices do not conflict with each other
 Host can read/write the resource and
transducer block parameters
 Device diagnostics may be accessed by the
host
