with direct connection to the till
The CREDIT-DEBIT system allows coffees to be dis-
pensed from the machine only after the beverages have
been paid for at the till.
The system is structured as follows:
Beverages are ordered
at the till.
Beverages ordered
at the till can be dispensed.
17.1.1 Installation
When installing, proceed as follows:
Turn the machine off;
Position switches 11 and 15 of the SW2 microswitch
battery in the ON position, as shown in the wiring
diagram;
Connect the standard CS serial cable (code: 22556004)
to the other end of the CC cable and to the till;
Turn the machine back on.
The till management software and the standard CS serial cable
is not the responsibility of the manufacturer.
YOU can use a different serial cable than the one supplied by
the manufacturer (code: 22556004) can be used, as long as it
is no longer than 15 metres.

17.1.2 Communication protocol
Description of the operating principle with reference
to the diagram shown below:
1. Order the beverage at the till;
2. Select the ordered dose on the coffee machine;
3. The code that corresponds to the selection is sent
to the till (see the code table);
4. The till replies with ACK=06H, thus enabling the
beverage to be dispensed;
5. The coffee machine dispenses the beverage.
If the till does not identify the code, the machine is
not enabled, the selection is not dispensed and the till
sends the NACK=15H code.
