Configuring The Data Interface As A Com Port; Data Input Format - Sartorius combics 1 Operating Instructions Manual

Data Interfaces
Configuring the Data
Interface as a COM Port
(datProt)
Configure the interface as a COM
port in the Setup menu as a COM1 or
UniCOM port under the "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 in
display updates. The number of display
updates comprising an output interval
is configured under menu item 6.3.
– Output of a printout as configured in
the Setup program (menu item 6.1.7).
Output is linked to the "Data Protocol"
menu item (datProt) (see page 100,
"Configuring Printouts").
If you do not activate and configure
a user-definable data record, the
printout 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
MP8 Binary
Purpose
With the MP8 interface you can connect
MP8-generation peripheral devices with
separate power supplies to the Combics
indicator.
Features
– The weighing instrument is used only
for determining weight values.
– The data interface transmits only
in MP8 binary protocol
– The application program for MP8
can be selected under menu item 3
– The program index 2 for MP8
can be selected under menu item 4.
– "MP8 interface emulation" is not
permitted in legal metrology.

Data Input Format

You can connect a computer to your
indicator to send commands controlling
weighing instrument functions and
applications via the interface 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" ("output to Port").
The string "ESC P CR LF" triggers this com-
mand.
