LIGHTED CASH CREDIT INTERFACE BOARD

The Lighted cash credit interface board senses all of the inputs from the dispenser func-
tion switches, and the cash/credit and push to start switches. In addition it regulates the
power to the lighted cash/credit and push to start buttons. Any problems with this board,
therefore can cause any or all dispenser switches (with the exception of the handle
switches) to be inoperable. In addition, because the lighted cash credit interface board is
connected in the display circuitry any problems with it can cause problems with the
consolidated display (scrambled display, blenk display, etc.).
The lighted cash credit interface board also contains a four position DIP switch which
must be set correctly in order for the board to operate properly. This DIP switch must be
set as follows:
Switch 1
Switch 2
Switch 3
Switch 4
Figure B-29 shows the lighted cash credit interface board and Figures B-30 through B-32
show the pinouts of its connectors.
