This protocol is not for only weight scales.
-
If there is a parity error, frame number error, base price not valid, negative or zero weight or the scale
is in error status, the scale responds with
NAK
to frames 1, 2, 3 or 4.

When the scale is on any error status, it responds with

E

Q
.
-
If the scale has a tare weight, it sends the net weight.
-
The scale wait until it has stable weight to responds to frames 1, 2, 3, 4 or 5.
-
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
and set the status to 21.
-
When the scale receives the frame 5 it responds with the same price and amount, it only adds the
weight.
