These listings are updated as assignments are issued.
The 64-bit unique registration number (URN) is the
basis upon which node-addressable, digital communication
takes place, within the multi-drop architecture of
the IEEE 1451.4 mixed-mode interface. The URN contains
an 8-bit family code (FD) to identify the functions
available in the node and the command set to be used
with the node. Each node must contain a 64-bit URN
to control access to the Transducer Electronic Data
Sheets (TEDS). The list of assigned URNs does not
have the 48-bit serial number or 8-bit Cyclic Redundancy
Check code (CRC). The list only contains the assigned
36-bit block number and family code.
