Read only transponder system for model rail systems has computer coupled to a number of readers

摘要

The read only system of a transponder system has a central processing facility (1) that can be a personal computer. This is connected to a bidirectional communication bus (2) that connects with up to 128 addressable readers (3). The processor also has a serial unidirectional bus (4) coupled to such as a display (5) or specific controller (6). In addition a RS 232 bus may be used to connect to other equipment.
