3.2 RS232 Program Port<br />

To facilitate configuration of the unit at production time, a separate program port<br />

will be required. The program port is an RS232 serial interface utilizing a 6 pin<br />

RJ-11 style connector with the pin out shown in Table 1. The program port will<br />

allow complete reloading of the controller firmware as well as supporting<br />

features such as downloadable fonts, graphics. Programming and creation of<br />

coupons must also be supported. Signal levels and protocol will conform with<br />

EIA-232 standards listed below.<br />
