Data Interface

Configuring the Data
Interface as a COM Port
(datprot)
You can configure the interface as a
COM port in either COM1 or UniCOM,
“Data Protocol” (datprot) menu item.
SBI communication
This is a simple ASCII interface.
Data output is configured under menu
items 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
intervals is set in menu item 6.3.
– Output of a configurable printout.
Output is linked to the “Printouts”
menu item (prtprot), (see page 81
“Configuring Printouts”)
If you do not activate and configure a
user-definable data record, the printout
simply contains the current value
displayed on the display and control
unit (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 scale
to send commands controlling weighing
instrument functions and applications via
the interface port.
All commands use the same data input
format. They start with the ESC character
(ASCII 27) and end 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 a max. of 7 characters
(4 command characters).
The commands listed in the following table
must each be supplemented with ESC ...
CR LF.
Example: The command character for
output is “P” (“output to Port”).
To trigger this command, send the string:
“ESC P CR LF”.

and a ... a: 1 to 20 characters for header x,
followed by the underline, CR and LF
