Abstract: A configurable I/O arrangement (100) for a controller has a number of internal and external input/output terminals, each of which are field selected as either an input or an output terminal. Logic functions (106) of the controller are configured for a number of output terminals using up to 32 internal logical states and the states of 32 external physical I/O points. The update timing for each logic circuit is selectable to be synchronized in several different ways: synchronous with an internal event within the controller, synchronous with an event external to the controller, and asynchronous. The I/O arrangement includes a combination of a synchronous latchable input state array (102) user configurable means (112) for logically combining the output signals of the reading circuits, and means for actuating external devices as a function of the logical combinations of the output signals of the reading circuits.

Abstract: A compact rf reader apparatus (10) integrated into a single compact package structure. In one embodiment, a rotatably adjustable head (18) is mounted on the compact reader body portion (12) containing read/write electronics (60) and an interface controller (68). The rotatably adjustable head contains an antenna (54) and is adapted to direct the antenna in numerous different directions without moving the compact reader body portion (12) of the rf reader. Additionally, in one embodiment, the rf reader unit (10) includes a switching power supply (62) located within the reader body portion (12). The switching power supply (62) is electrically coupled to the read/write electronics (60) and the interface controller (68), and is synchronized with the transmitting frequency of the antenna to prevent interference.
