FT-107 Weighing Terminal, Technical Manual, Rev. 1.0.0, August 2019 Page 43 of 46
8. SERIAL DATA FORMATS
Continuous data and single line data format are described in this section. FT-107´s serial ports are suitable for
bi-directional communication. If you transmit ASCII codes for P(print), Z(zero), T(tare) or C(clear) to the one
of the serial ports, the indicator will act like the related keys are pressed.
Continuous-1 Data Format
The data format of the Continuous-1 data output:

Status C (STC) is always hex ‘30’.
Note: The weight data is represented with right aligned and the error messages (UNDER, OVER and A.OUT)
are represented with left aligned in indicated data field.
Continuous-2 Data Format
The data format of the Continuous-2 data output is;
[STX][STATUS][SIGN][INDICATED WEIGHT VALUE][UNIT][CR][LF][CHK]
Examples :
S+000123.4kg (weight is stable and 123.4)
D+000123.4kg (weight is dynamic and 123.4)
+ (Over load)
- (Under load)
O (ADC out error)
Checksum Calculation:
CHK (Checksum) = 0 – (STX + STATUS + ..... + LF)
Single Line Data Formats
Single line data output of the instrument is transmitted in the following data structure.
