SERIAL DATA FORMATS
Weight-On-Demand
If the Printer Continuous output was not selected,
COnt=0
(0=NO) during setup and calibration
of the indicator, and the 204 is connected to a computer, it will transmit a single set of weight
data each time the computer sends an ENQ (hex 05) or a SMA weight request (W). This is
known as Weight-On-Demand. Eamples and explanation of the data format transmitted are
shown below.
Continuous Output
If the Printer Continuous output was selected
COnt=1
(1=YES) during setup and calibration,
the 204 will transmit weight data continuously. If connected to a remote display, the display
will continuously show weight data. An example and explanation of the data format
transmitted is shown below.
Weight-On-Demand And Continuous Output Data Format
The data format transmitted for
both
Weight-On-Demand and Continuous Output will be
GROSS weight only. The weight data always includes the units of measure. An example of
the data output (with and without a decimal point) is shown below:
Pxxxxx^UU^M^SS^CR
(no decimal point in weight display)
PxxxxxD^UU^M^SS^CR (decimal point in weight display)
where:
P = Polarity (space if positive, - if negative)
xxxxx = Weight (with leading spaces)
^ = Space
D = Decimal Point (embedded where necessary)
UU = Units LB, KG, OZ, ^G
M = Mode G = (gross)
SS = Status CZ = center-of-zero, O = motion,
BZ = below zero and OC = over capacity)
CR = Carriage Return (hex OD)
SMA Weight On Demand Format
The host device (computer) sends:
<lf> W <cr>
The 204 will respond:
<lf><s><r><n><m><xxxxx><uuu><cr>
where:
lf = Line Feed
s = Flags Z= center of Zero, O = Over cap, E = zeroError,
e = weight not currently being displayed
r = Range 1, 2, 3, ...
n = Mode G = Gross
m = Motion M = Motion, " "(
blank
) = no motion
xxxxx = Weight Five digits
uuu = Units lb^, kg^, oz^, g^^ (^ = space)
cr = Carriage Return (hex 0D)
