CONFIDENTIAL Page 2of 4 Author: C. E. Daily. Diomed Limited 30 July 2003 AutoID Module Circuit Overview The AutoID circuit is implemented on a four-layer surface mount printed circuit board (PCB 044 issue1). One of the layers is used for +5V, and one as a ground plane. The other two are used for signals. The circuit consists essentially of a RFID base station IC, an integral PCB antenna coil, an AVR microcontroller, and a RS232 driver. See fig 1. Fig. 1 AutoID Block Diagram Connection to D15plus / D30plus Lasers The AutoID module is connected to the Laser via an RS232 port. This connection is made via an IDC connector/ribbon cable assembly. A MAX232A converts the RS232 signals to 5V logic levels for the AVR micro-controller (ATmega 8515L). 16 way IDC connection details.
