Data Interfaces
Configuring the Data
Interface as a COM Port
(datprot)
Configure the interface as a COM port
in the Setup menu under COM1 or
UniCOM, under the "Data Protocol"
(datprot) menu item.
SBI Communication
This is a simple ASCII interface.
Data output is configured under menu
lines 6.1 and 6.3:
– Manual output of displayed value with
or without stability (menu items 6.1.1
and 6.1.2)
– Automatic output of displayed value
with or without stability (menu items
6.1.4 and 6.1.5) at intervals defined by
display updates. The number of display
updates comprising an output interval
is configured under menu item 6.3.
– Output of a configurable printout.
Output is linked to the Printout
(prtprot) settings.
If you do not activate and configure a
user-definable data record, the print-
out simply contains the current value
displayed on the indicator (weight with
unit, calculated value, alphanumeric
display).
SMA Communication
Standardized communications protocol
of the Scale Manufacturers Association
Data Input Format
(Commands)
You can connect a computer to your
display and control unit to send com-
mands controlling weighing instrument
functions and applications via the inter-
face port.
All commands use the same format
(data input format) starting with the
ESC character (ASCII 27) and ending
with a carriage return (CR; ASCII 13)
and a line feed (LF; ASCII 10). The total
length of a command is anywhere from
4 characters (1 command character
between the start and end described
above) to 7 characters (4 command
characters).
The table below shows the available
command characters; each command
must be flanked by the start and end
characters as described above.
Example: The command character for
output is "P" ("transmit readout value").
The string "ESC P CR LF" triggers this
command.
