2. Answer from the scale in Basic Protocol and pulsator:
S - Sign: blank space (20h) if the result is zero, and
'minus' (2Dh) if the result is less than 0.
SP - Blank space: 20h.
PP.PPP - Value of the weight (6 bytes) with decimal point,
no sign and justified with blank spaces (0x20d).
CR - Character (0x0d, 13d).
LF - Character (0x0a, 10d).
3. Answer from the scale in Extended Protocol (await request) and pulsator:
ESC - Character 0x1B.
E - Stability: 'S' if the result is stable, and 'U' if the
result is unstable (weight negative, over or under,
always 'U').
S - Sign: blank space (20h) if the result is zero, and
'minus' (2Dh) if the result is less than 0.
PP.PPP - Value of the weight (6 bytes) with decimal point,
no sign and justified with blank spaces (0x20d).
CR - Character (0x0d, 13d).
LF - Character (0x0a, 10d).
TPV 10 (VECTRON Protocol):
The scale continuously sends the weight when the TPV enables (set) the
DTR signal. As the Eco Multifunction scale does not have DSR, the TPV's DTR is
input through RxD of the scale's RS-232 communication connector. This requires a
special cable.
The trace of the message sent by the scale to the TPV is the following:
<ID (2 bytes)><SEPARATOR (2 bytes)><DATA (6 bytes)><Units (2
bytes)><CR><LF>
