Page 7: Product Function
25 July 1996 Micro-reader Module Product Function 2.1 Description The Micro-reader module is an intelligent 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. -
Page 8: Synchronization
Micro-reader Module 25 July 1996 2.1.3 Synchronization There are two possible methods of wired synchronization: 1. Connect a pulse waveform to all RDEN- input pins of the Micro-readers to be synchronized. The pulse would normally be at VSL, dropping to GND for 100 µs every 200 ms. 2. -
Page 9: Serial Communication
25 July 1996 Micro-reader Module In the default continuous read mode, only those valid RO, R/W or MPT IDs that differ from the previously read ID; or valid IDs read after a “NO READ”, are transferred via the SCI (Normal Mode) he Micro-reader can be set to transfer all valid IDs that are read (Line Mode) by means of a corresponding serial data command... -

This output is at GND level until the Micro-reader starts its read cycle, at which time it goes to VSL until the complete reading, programming or locking cycle is finished.
- Page 12 Micro-reader Module 25 July 1996 VSL (24) Pin 24 is for connecting the positive supply voltage (5 V) for the logic part. CRDM (26) Supplying pin 26 with a logic high signal causes the Micro-reader to run in a continuous charge-only read mode (see Section 2.1.5 for more information).
