Configuring The Data Interface As A Com Port; Data Input Format - Sartorius Signum 1 Operating Instruction

Configuring the Data
Interface as a COM Port
( datProt )
Configure the interface as a COM port
in the operating 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
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
updates comprising an output interval
is configured under menu item 6.3.
– Output of a configurable printout.
Output is linked to the "Printouts"
menu item ( prtprot ) (see page 80,
"Configuring Printouts;" for details
on operating menu settings, see
pages 34–35.
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
MP8 Binary (as of mid-2007)
Purpose
With the MP8 interface you can
connect MP8-generation peripheral
devices with separate power supplies
to the Signum display and control unit.
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

(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, 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 com-
mand can be 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
described above.
Example: The command character for
output is "P" ("output to Port"). The string
"ESC P CR LF" triggers this command.
Command Meaning
K Weighing mode 1
L Weighing mode 2
M Weighing mode 3
N Weighing mode 4
O Block all keys
P Output readout

character is 95.
Format for entering printout header lines:
ESC z x a ... a _ CR LF where x=(header
line) 1 or 2; a ... a: = up to 20 characters
of text, followed by the "underline"
character, carriage return and line feed.
