NOTE:
-
The
X
can take the values:
o
' ' (0x20): when the weight is valid.
o
'F' (0x46): when the weight is erroneous or invalid.
o
'
–' (0x2D): when the weight is negative (for example: Tare without plate).
-
The
S
can take the values:
o
„S‟ (0x53): when the weight is stable.
o
„U‟ (0x55): when the weight is unstable.
-
If the weight is unstable momentary value is sent in the field
WW.WWW.
For the answer
D
2
, the price
entered on the scale is sent and the amount is sent to 0.
-
If the weight is erroneous (with "--------" on the display) the Scale replaces the X and the weight by
FFFFFFF. In the case of the D2 response frame, the price is the entered on the Scale and the
amount is displayed to zero.
-
If the scale has a tare weight, it sends the net weight in the field WWWWW.
-
If when the frame
D
2
is sent the weight is negative, the scale responds with the price entered on the
scale and the amount to zero.
-
If the scale receives a frame with an incorrect format, the scale responds with
NAK
.
-
The scale takes into account the minimum weight adjustment. If this adjustment has the value 1 the
scale responds with
NAK
if the weight is lower than 20 steps.
-
Between different requests the weight must vary at least 20 steps or pass through zero, otherwise the
scale responds with
NAK.
-
The minimum variation or zero crossing, and adjustment of minimum weight, also affect to request
frame of only weight
