5.8. Continuous Output Data Structure (for FAD-30 + FAD-30MB
only)
The continuous data output of the instrument will be transmitted in the following data structure at the speed
which is determined by the baud rate and the data length. The definition of the continuous data format is
described below.
In weighing mode and force mode:
Status Indicated Tare
STX STA STB STC D5 D4 D3 D2 D1 D0 D5 D4 D3 D2 D1 D0 CR LF CHK
In count mode:
Status Count Data Not used
STX STB D7 D6 D5 D4 D3 D2 D1 D0 D5 D4 D3 D2 D1 D0 CR LF CHK
The definition of the status bytes STA, STB and STC is described below.

Error Messages: UNDER, OVER, A.OUT, L-VOLT, H-VOLT are annunciated in the Indicated or Count Data
fields.
Note: Weight data is represented with right alignment, error messages with left alignment.
