What selective identification feature (SIF) mode has a limit of 32 codes?

The selective identification feature (SIF) mode that has a limit of 32 codes is the first mode. This mode is designed to accommodate a range of 32 distinct identification codes, allowing for effective tracking and identification of various items or assets within a system. This limitation is significant in contexts where precise identification is necessary, as it establishes a specific framework within which the SIF operates.

The nature and structure of the identification codes in this mode simplify the process of management and oversight, making it easier for users to maintain an organized system. In contrast, the other modes, while capable of supporting more or different functionalities, either expand the number of codes available or change the parameters of how identification occurs.
