Data Transmission And Saving To File
If data transmission is enabled in the menu 'Data Entry/Settings/General', after each weighing cycle data are
transferred to the host system.
When the 'AckNak' protocol is used, receipt of data must be confirmed by the host system with ACK(06H)
within 3 sec. In the case of an error, NAK(15H) can be returned to initiate a repetition of the transmission.
Always the oldest record in the buffer is transmitted and deleted from the buffer after successful
transmission.
The weighing data can also be saved in a file, to this effect the parameter 'Store on USB device' must be
enabled in the menu 'Data Entry/Settings/General'.
Numeric fields are represented in ASCII format with variable position of decimal separator and leading space
characters to fill non-significant places. In the configuration decimal point or comma can be selected as
decimal separator.
The individual data fields are separated from each other by semicolons. The length of the data fields is
variable, control characters -if applicable- are added.
Fields that are not used in the chosen operating mode remain empty in the data string. Depending on the
chosen operating mode, the same data fields are used for different variables.
