and connect to a promotional controller over a serial communication bus using a protocol<br />

such as RS-232. The interface board also includes a real time clock that is used by the<br />

microcontroller on the motherboard of Exhibit D.<br />

14. A copy of a schematic drawing of the interface board of Ex_ru'bitF is<br />

shown in Exhibit G. The schematic was taken from FutureLogic's electronic archives and<br />

has not been modified since it was approved by me on a date before July 10, 2001. Dates<br />

printed on the schematic have been redacted, but are all prior July 10, 2001.<br />

15. As shown on the left side of the schematic, the interface board<br />

includes connector J2 for a 2x4 "Molex" style connector for MDB signal lines M_ILK and<br />

M_TX. Molex connector in the schematic corresponds to the Molex connector of the ma'm<br />

communication port shown in Exhibits C and F. These signal lines are muted through<br />

optoisolators IC3 and IC4 to buffer IC2-B. The signals lines are then routed from the<br />

buffer IC2-B as MDB transmission signal line TXD_MDB and IvlDB received signal line<br />

RXD_MDB to multiplexer IC6 shown in the center of the schematic. In addition, as shown<br />

on the right side of the schematic, connector J4 is provided for a DB9 style connector for<br />

routing RS-232 signals. The DB9 connector corresponds to the DB9 connector for the<br />

auxiliary communication port shown in Exhibit D. Connector J4 is connected to connector<br />

J3 _,ia a r_bon cable and the RS-232 signal lines TXD_DB9 and RXD_DB9 are routed to<br />

RS-232 transceiver IC1. From ICI, RXD and TXD signal lines are routed to the<br />

multiplexer IC6. From the multiplexer IC6, a single set of RX and "IX signal lines are<br />
