Micro-Reader Module - Texas Instruments 2000 Series Reference Manual

General
1.1 General
The Micro-reader is an intelligent module providing RF and Control functions to read and program TIRIS
transponders. It is equipped with a Serial Communications Interface (SCI) which may be directly
connected to commonly used system controllers. The Micro-reader works together with a 47 µH, low-Q
antenna, and therefore the system does not need tuning.
1.2 Product Description
The Micro-reader module is a plug-in module which can be plugged into or soldered onto an application
specific adapter board. It supports serial data communications between a PC and TIRIS transponders.
With its Serial Communications Interface (SCI) the Micro-reader supports TTL data communications,
which with the addition of a communications driver (for example: RS232 or RS422) allows communication
to a standard interface.
The Micro-reader can be controlled remotely by either providing certain inputs with the corresponding
voltage level or sending commands to the SCI. It can be driven either with or without synchronization - the
synchronization can be either wireless or wired to enable reliable operation in multi-reader environments.
Two outputs show the reader status and inform the user about a successful command execution. The
Micro-reader supports all available TIRIS™ LF transponders.
