CPU BOARD
The CPU board (Central Process Unit) manages all
intended users for maximum conguration and manages
the incoming signals from a keyboard, payment system
and manages the activations card.
The LEDs, during the operation, give the following indi-
cations:
- the green LED (26) flashes during the normal operation
of the CPU board;
- the yellow LED (28) is on in the presence of 5 Vdc;
- the red LED (27) is on when there is, for any reason, a
reset of the software.
softWare update
The machine is equipped with Flash EPROM which can
be rewritten.
By means of an appropriate programme and a suitable
system (PC or PDA) it is possible to rewrite the man-
agement software of the machine without replacing the
EPROMs.
