INTER-SYSTEM CONNECTION ADAPTER AND TERMINAL

摘要

An inter-system connection adapter, and a terminal, in which a new function developed by a manufacturer on the existing system A side can be handled on an open system B configured according to a different protocol and the function can be extended easily. The inter-system connection adapter adds a command unique to a conventional system A not defined in the open system B and not capable of being correlated to a frame header B by a frame encapsulating/decomposing means and transmits it as it is. The terminal connected to the system B side has a function of extracting a command A from a transmitted frame B and interpreting/processing the command A.
