    SC-350/360 Computer Communication 12 Computer Communication 12.1 Serial Interface The communication is carried out via an RS232C interface where SC 350/360 is classified as Data Terminal Equipment (DTE). The data format is 9,600 baud, 8 bits, no parity bit and one stop bit. SC 350/360 works as a slave, that is only the computer can take the initiative to perform any data exchange with the machine.

    SC-350/360 Computer Communication 12.4 Logging Off When communication between the computer and the machine has finished, the machine should be “logged off”. This puts the machine into the same state as when it is switched On. This is achieved by sending the following message: Computer (PC) SC-350/360...

    SC-350/360 Computer Communication 12.10 Reading the Number of Counted Coins Revision 1.xx of the protocol: The machine sends the number of counted coins since the last zero reset as a 16-bit number. If batch counting is disabled, zero will be transmitted.

  • Page 93: Reading Batch Quantity Value

    SC-350/360 Computer Communication 12.11 Reading Batch Quantity Value Revision 1.xx of the protocol: The machine sends the current batch quantity value as a 16-bit number. If batch counting is disabled, zero is transmitted. The batch quantity value is the temporary quantity of the machine. The message does not affect any register.

    SC-350/360 Computer Communication 12.12 Setting a New Batch Quantity Revision 1.xx of the protocol: The computer sends the new batch quantity value as a 16-bit number. The machine reads this as a temporary batch quantity. Batch counting is disabled if the batch quantity value is zero. Computer (PC) SC-350/360 –––––––>...
