Page 72: Additional Transmission Parameters
Use and warning instructions NOTE If the archive cannot be completely emptied with the last weighing of the work shift or day, it is possible to do so without carrying out an additional weighing operation. In fact, it is sufficient for the PC to send the ENQ character (05 hexadecimal) to the terminal and the archive will be emptied by temporarily adopting the transmission mode “Archive”.
Page 73: Calculating The Checksum
SEL 700 If the string is received correctly, the PC must send, within a time defined in seconds during installation, a single character: ACK (06Hex). If the “printed data string” was enabled in “single mode”, the ack/nak protocol can also manage the character BEL (07Hex): the PC must send the character BEL, within the time (in seconds) defined during installation, when it received the data string correctly but is not yet capable of authorising the weighing operation.
