Scale answer
<$>(0x24, 36d)
The scale transmits the weight with the
following trace:
<PPP.PPP><CR>
Scale answer:
<PPP.PPP> - Value of the net weight with 7 bytes including the
decimal point and left-justified with zeros (0x30)
<CR> - Character 0x0d.
• Special cases of this protocol:
d.1.-] Net weight zero and stable: Sends '0000000<CR>'
d.2.-] Net weight over or under: Sends 'AAAAAAA<CR>'
d.3.-] Net weight in range and stable: Sends 'PPP.PPP<CR>' (the value of
the weight with 7 bytes including the decimal point and justified with zeros
on the left.
d.4.-] Net weight in range, stable and negative: Sends the string described
in section 'd.2.-]'.
d.5.-] Net weight in range and unstable: The scale retains the weight
request indefinitely until it becomes stable, when the scale operates as
described in section 'd.3.-]'.
• Transmission started by the scale at the beginning
a.-] When the scale is powered on and the initial sequence is completed, it
indicates that it is ready by sending the sequence: '0000000<CR>', described
previously.
