Scale →Computer: without response,
setting low threshold value:
Computer→ Scale: S L D1...DN CR LF (53h 4Ch D1...DN 0Dh 0Ah)
D1...DN – threshold value, maximum 8 characters („-” – negative value, digits,
dot – decimal separator), number of digits after dot should be the same as on
scale display,
Scale →Computer: without response,
Example:
⋅ in order to set low threshold 1000g in scale B1.5 (d=0.5g) the following order
should be sent:
S L 1 0 0 0 . 0 CR LF (53h 4Ch 31h 30h 30h 30h 2Eh 30h 0Dh 0Ah),
⋅ in order to set low threshold 100kg in scale B150 (d=50g) the following order
should be sent:
S L 1 0 0 . 0 0 CR LF (53h 4Ch 31h 30h 30h 2Eh 30h 30h 0Dh 0Ah),
setting high threshold value:
Computer→ Scale: S H D1...DN CR LF (53h 48h D1...DN 0Dh 0Ah),
D1...DN – threshold value (see )
Scale →Computer: without response.
Note:
Network number different than zero (F..-rS / nr function) changes scale working
mode: communication with a computer is possible after logging the scale in with
02h scale_number command. To log the scale out use 03h command.
The description of data transmission protocol in automatic mode
Every time weighing is done in the moment when indications becomes stable the
scale sends successive three-digit number (counter value) and result of the
weighing. If an indication is zero there is no transmission from the scale.
Weighing counter is cleared after each choosing of automatic mode (see further –
LPt function).
The sequence of sending values is the following:
