PRINTER OUTPUT

The Model 6745 Baby Scale has a RS-232 serial port that may be connected to an optional

printer to record weight. The output connector is located on the rear panel (see Figure No. 6).

When the weight display is locked on the baby’s weight and the Weight Lock annunciator is

turned on, the weight data may be transmitted by pressing the PRINT key or on demand with

receipt of a command from a computer). NOTE! If the threshold feature was enabled during

setup and calibration, with a printer attached to the scale, the weight data will automatically

print when the weight display locks on the baby’s weight.

Figure No. 6

The serial port can be configured during the setup and calibration procedure or during the

setup review operation. Using either method, it is possible to select the baud rate, data format

and print ticket format. NOTE! The scale is shipped with the baud rate set to 9600 baud.

SERIAL DATA FORMATS

If the scale 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). Examples and explanation of

the data format transmitted are shown below.

The host device (computer) sends:

ENQ (hex 05) or <lf> W <cr>.

The scale will respond with:

<lf><s><r><n><m><xxxxxxxxxx><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:xx.x =

xxxxxx.xxx =

Weight Ten digits (includes decimal point), lb/oz mode

Ten digits (includes decimal point), kg mode

Weight is right justified.

uuu = Units l/O^ (lb & oz), kg^ (kilograms), (^ = space)

cr = Carriage Return (hex 0D)
