Refer to the technical specifications for dosing for their correct configuration.<br />
Connection is made by means of an RS232 serial line, with the appropriate cable.<br />
Serial transmission characteristics:<br />
• BAUD RATE 1200 bit/sec<br />
• DATA LENGTH 8 bit<br />

espresso coffee machine - servings count<br />
Operation<br />
A code corresponds to each dosing key. When a serving is requested from a certain key, the dosing device sends the relative code by means<br />
of its serial line. If it receives in reply the same code or a code from 1 to 15 (decimal) the serving is delivered, otherwise it is deleted. The<br />
codes are typical of the traditional interface with the Gicar Stroke Count, which transmits a code that makes it possible to recognize the<br />
staff that is using the machine (1...13 : waiters, 14 : manager, 15 : owner).<br />
List of codes used by dosing:<br />
• 11H Group 1 Key 1<br />
• 12H Group 1 Key 2<br />
• 13H Group 1 Key 3<br />
• 14H Group 1 Key 4<br />
• 15H Group 1 Key Tea 1<br />
• 16H Group 1 Key Tea 2<br />
• 17H Group 1 Stop/Cont/Prog Key (Dosmask series)<br />
• 19H Group 1 Stop/Cont/Prog Key (Dosmask series)<br />
• 21H Group 2 Key 1<br />
• 22H Group 2 Key 2<br />
• 23H Group 2 Key 3<br />
• 24H Group 2 Key 4<br />
• 25H Group 2 Key available<br />
• 26H Group 2 Key available<br />

The system replies code 15 (decimal), thus enabling delivery of the serving (even if the activation key is inserted).<br />
During any data reading or deletion operation, the system does not reply or replies with a code which is not recognized by the dosing. In this<br />
case, delivery is not performed and the serving is not counted.<br />
