In communications systems having multiple terminals in a loop or similar configuration, the communication is generally facilitated by assigning specific addresses to each terminal so that messages may be routed from the central communication host system to the individual terminals and back. A problem encountered in systems of this type is that each terminal must have a specific unique address. This is generally incorporated as a part of the hardware or is set by switches or programming during installation. As a result, when a terminal becomes defective and is in need of service or replacement, spare terminals must be available with specific hardware addresses that must be different from the one replaced or the installer must initiate a setup procedure for personalization of the terminal utilizing programming or switches.
